Agenda Items 4, 4a, 4b, and 4c – RR266 JOU Combined Single Resource Modeling post Settlement Share Allocation IA John Luallen (SPP) presented three Impact Analyses for implementation timing and cost associated with RR266 (JOU Combined Single Resource Modeling post Settlement Share Allocation): Option 1 – Development, testing and implementation concurrent with the Settlement System Replacement Project, Option 2 – Development concurrent with the Settlement System Replacement Project, but testing and implementation after implementation of the new Settlement System, and Option 3 – Development, testing and implementation all occur after the new Settlement System Replacement Project. John proposed an alternative approach to address the settlements portion of the proposed design outlined in RR266, which would involve creating a new JOU adjustment charge type instead of altering the 40+ charges and credits that currently apply to JOU Resources. John explained this approach could be implemented with any of the three Impact Analyses timing options, but noted the cost could change. The group expressed interest and requested SPP provide an additional impact analysis to assess the cost if developed, tested and implemented with the Settlement System Replacement Project (Impact Analysis Option 1). Erin Cathey (SPP) stated SPP will target the April MWG meeting to provide a new Impact Analysis for the alternative settlements approach. Although a number of MWG stakeholders voiced concern with the cost associated with the design overall, the Option 1 Impact Analysis was approved with a High rank. Due to MWG direction to further assess the cost associated with alternative settlements approach, SPP will not begin work to further develop the market design for RR266 until the Impact Analysis for the alternative settlements approach is complete and has been reviewed by the MWG. Motion: Jim Flucke (KCPL) motioned to approve RR266 (JOU Combined Single Resource Modeling post Settlement Share) Option 1 Impact Analysis with a High rank. Cliff Franklin (WR) provided the second. Motioned carried with five oppositions from Kevin Galke (CUS), Valerie Weigel (Basin), Rick Yanovich (OPPD), Shawn McBroom (OGE) and Richard Ross (AEP) and one abstention from Carrie Dixon (Xcel). See Attachment 6 – RR266 Impact Analysis with Settlement System, Attachment 7 – RR266 Impact Analysis Hybrid, Attachment 8 – RR266 Impact Analysis after Settlement System, and Attachment 9 – RR266 Recommendation Report Action Item: Staff will determine if a manual solution can be put in place to allow MPs the ability to utilize the Combined JOU logic proposed in RR266 while the systematic logic is developed, tested and implemented. Staff will target the April MWG meeting for further discussion. Agenda Item 5 – RR273 Market Settlements RNU Rounding John Luallen (SPP) presented RR273 (Market Settlements RNU Rounding). Per SPP’s tariff, SPP must remain revenue neutral and as such must calculate charge/credit amounts at each Settlement Location for each Asset Owner for each hour on a daily basis. This can result in residual amounts remaining due to rounding, which puts SPP in a position of not being revenue neutral for a given Operating Day. The

residual is summed on a yearly basis and uplifted to Asset Owners and Settlement Locations. This is performed manually through SPP’s Miscellaneous Adjustment. John explained the objective of the RR is to eliminate the manual processing of residual amounts through the Miscellaneous adjustment and instead automate the distribution of the residual amounts through the RNU process. John detailed six charge types to be incorporated into the RNU process. The group inquired of the magnitude of dollars involved, to which John stated it is minimal. Although some MWG stakeholders expressed interest in considering an alternative approach, such as allocating the residual amounts to the SPP Administration Charge, the RR was approved. SPP staff plans to research this suggested approach, and if determined feasible, will provide an alternative revision request to the MWG for consideration during the March MWG meeting. See Attachment 10 – RR273 Market Settlements RNU Rounding Motion: Kevin Galke (CUS) motioned to approve RR273 (Market Settlements RNU Rounding). Valerie Weigel (Basin) provided the second. Motion carried unanimously. Agenda Item 6 – 2016-2017 ARR Holders % Hedged Debbie James (SPP) explained incorrect 2016/2017 Congestion Hedging % by Asset Owner data was presented during the August 2017 MWG meeting (related to closed MWG action item 317). Staff discovered the error during later analysis noting that several ARR holders that received Day-Ahead Market congestion payments instead of charges should have been shown as having no exposure instead of a hedged %. Debbie noted that the SPP GFA Carve out ARR holders are included in the corrected data, showing 52 ARR holders rather than 51, and that GFA ARR holders over 100% are also included. In the correct data SPP shows 20 AOs with no exposure which is a large contrast the 6 AOs previously shown with no exposure. Graphs and charts exhibiting the incorrect and correct versions of the data presented are included in MWG materials. See Attachment 11 – 2016 ARR Holders Percent Hedged Correction Agenda Items 7, 7a, 7b, 7c, and 7d – ARR/TCR Process Discussion Richard Ross recommended next steps to move towards completion of MOPC action item 276 - ARR/TCR inability to hedge as expected. He suggested researching potential options to address the issue of TCRs with small impacts consuming a disproportionate share of the awards and crowding out the larger impacting requests, possibly by adjusting the ARR process to align with the Transmission study process such that requests having less than a 3% impact are not included. Stakeholders voiced the need to develop a solution that would reduce uplift. Richard also facilitated a discussion of ARR/TCR process training. The group provided suggestions for additional training. Several stakeholders expressed an interest in more detailed training overall, and would like to see this provided in a workshop forum, possibly in-person prior to a MOPC meeting. Specific training requested included a deeper dive to look into the ARR allocation model and TCR auction model, including examples of a small system impact and a percent change impact and training to help stakeholders better understand the TSR process starting with the study process. Staff will work to provide a schedule and plan to address the training requested at the March MWG meeting. See Attachment 12 – Recommended Congestion Hedging Related Training and Attachment 13 – MOPC AI 276 Detailed Progress Summary

Agenda Item 8a – NDVER to DVER Conversion Analysis and 8b – RR272 NDVER to DVER Conversion Erin Cathey (SPP), Gary Cate (SPP), and Casey Cathey (SPP) facilitated a review and discussion of the Non-Dispatchable Variable Energy Resources (NDVER) to Dispatchable Variable Energy Resource (DVER) Conversion Analysis Report provided to the MWG. Erin highlighted details of the NDVER capacity existing in SPP’s market and explained the individual Resource analysis was based on analysis performed at the request of an MP on one of their specific Resources to eliminate confusion where some questioned why SPP chose the specific Resource. The group discussed the analysis in detail and requested additional analysis be performed to show the impact of converting other NDVERs. Gary and Casey discussed SPP’s reasoning in proposing the NDVER conversion and explained why the effort is important and beneficial to the SPP market, speaking specifically to market inefficiencies and Reliability concerns. Keith Collins (SPP MMU) voiced the SPP MMU’s desire to see this effort completed, stating the MMU believes converting NDVERs to DVERs will create an overall more efficient market. SPP staff reiterated that with RR272 (NDVER to DVER Conversion), an MP would be able to request a waiver from FERC exempting them from conversion. See Attachment 14 – NDVER to DVER Conversion Analysis and Attachment 15 – RR272 NDVER to DVER Conversion Motion: Matt Moore (GSEC) motioned to approve RR272 (NDVER to DVER Conversion), Lee Anderson (LES) provided the second. The motion was tabled. Motion: John Varnell (Tenaska) motioned to table the motion to approve RR272 (NDVER to DVER Conversion), Cliff Franklin (WR) provided the second. Motion carried with three oppositions from Lee Anderson (LES), Richard Ross (AEP), and Matt Moore (GSEC) and three abstentions from Shawn McBroom (OGE), Shawn Geil (KEPCO), and Aaron Rome (Midwest). Motion: Matt Moore (GSEC) motioned to approve RR272 (NDVER to DVER Conversion) as amended via a Friendly Amendment by Carrie Dixon (Xcel). The Friendly Amendment did not receive any opposition from the group. Lee Anderson (LES) provided the second. Motion carried with seven oppositions from Shawn Geil (KEPCO), Cliff Franklin (WR), Ron Thompson (NPPD), John Varnell (Tenaska), Rick Yanovich (OPPD), Michael Massery (AECC) and Jim Flucke (KCPL) and one abstention from Kevin Galke (CUS). Agenda Item 8c – RR272 NPPD Comments 020118 Ron Thompson (NPPD) summarized NPPD’s comments and answered questions from the group. Ron noted concern with the following: cost impacts to conversion not considered and compensated by the market, converting type I and II turbines may result in additional maintenance costs and increased risk with no chance of cost recovery from SPP, impact of non-firm Resources on congestion, and SPP proposing changes to market rules in general which potentially places added cost burden on the SPP member utilities. More detail is provided in the submitted comments posted with materials. See Attachment 16 – RR272 NPPD Comments 020118 Agenda Item 8d – RR272 Westar Comments 020218

Cliff Franklin (Westar) summarized Westar’s comments to RR272 (NDVER to DVER Conversion) and answered questions from the group. Cliff noted Westar agrees with NPPD comments and added additional concerns. Cliff asked staff why an RR had not been pursued to address the price following concerns and asked several questions related to the NDVER Conversion Analysis report provided by SPP. Erin explained SPP did introduce the idea of establishing thresholds which would indicate price following and require reregistration as a DVER but the idea was not accepted by the MWG (late 2014). Erin and Gary answered Westar’s questions related to the NDVER to DVER Conversion Analysis report noting that the report was updated to address the questions and add clarity. Cliff highlighted Westar’s concerns with existing PPA contracts, stating RR272 forces NDVER conversion and abrogates NDVER contracts making RR272 unjust and unreasonable. Finally, Cliff notes the RR puts SPP’s market reputation at risk due to SPP providing the conditions for NDVERs at the beginning of the SPP Integrated Marketplace. See Attachment 17 – RR272 Westar Comments 020218 Agenda Items 8e – RR263 NDVER to DVER Conversion through Incentives and 8f – RR263 Westar Comments 020318 Cliff Franklin (Westar) summarized Westar’s comments to their RR263 (NDVER to DVER Conversion through Incentives) and answered questions from the group. Cliff explained Westar’s comments are intended to address MWG member and SPP staff comments that were discussed during the January MWG meeting. Cliff summarized the comments and grouped responses in four areas; curtailment payment obligation allocation, responsibility for upgrades to convert NDVERs, favorable treatment resulting from providing incentives, and value of incentives if PTC and rate exposure are not considered in formulating negative resource offers. Cliff highlighted language changes to correctly calculate payments to proposed NDVER-DCPL facilities for DA and RT asset energy. See Attachment 18 – RR263 NDVER to DVER Conversion through Incentives and Attachment 19 – RR263 Westar Comments 020318 Agenda Item 8g – RR274 NDVER to DVER Conversion through URD Chandler Brown (SEPC) summarized Sunflower’s RR274 (NDVER to DVER Conversion through URD) and answered questions from the group. Chandler explained the intent and benefits of the proposed design, stating NDVERs would be discouraged from chasing price by means of a penalty which mimics SPP existing URD logic. He explained the proposed design is just a starting point and additional work to fine-tune would be needed. See Attachment 20 – RR274 NDVER to DVER Conversion through URD Agenda Item 8h – RR274 NPPD Comments 013118 Ron Thompson (NPPD) summarized NPPD’s comments to RR274 (NDVER to DVER Conversion through Incentives) and answered questions from the group. See Attachment 21 – RR274 NPPD Comments 020118 Agenda Item 8i – RR274 Olympus Power Comments 013018 John Varnell (Tenaska) summarized Olympus Power’s comments to RR274 (NDVER to DVER Conversion through Incentives) and answered questions from the group. See Attachment 22 – RR274 Olympus Power Comments 013018

Agenda Item 9 – Multi-Day Minimum Run Time Solution Debbie James provided an update on the status of the multi-day minimum run time solution. She refreshed the group on the options provided during the February MWG meeting: Option 1 – No MWP after 24 Hours, Option 2 – Binding Offer at Minimum Energy for the Minimum Run Time, and the OGE Option – MWP to be lesser of the Mitigated Offer or Energy Offer for the balance of the minimum run time after the first 24 hours. Keith Collins (SPP) noted the SPP MMU’s concern that the proposed option from OGE may, although closing one, create a new loophole. The new loophole may present an incentive for MPs to offer in order to be committed and receive MWPs associated with the mitigated offer in subsequent days. Keith proposed a modification to OGE’s option. He recommended that if the “as-committed” energy offer and/or “as-committed” no-load offer is less than the mitigated energy and/or no-load offers, the MP will not be eligible to receive a MWP after the first 24 hours of its resource’s minimum run time. OGE voiced support for this option and offered to work with SPP staff to develop a revision request. See Attachment 23 – Multi-Day Min. Run Time Gaming Issue_Options Agenda Item 10 – RR270 OCRTF Revisions to Operating Criteria Appendices Neil Robertson (SPP) presented RR270 (OCRTF Revisions to Operating Criteria Appendices). Neil explained this RR was initiated by the Operating Criteria Review Task Force (OCRTF) and creates a stand-alone document for outage coordination methodology. Neil walked through the language in the RR and answered questions. The group unanimously approved the Revision Request. See Attachment 24 – RR270 OCRTF Revisions to Operating Criteria Appendices Motion: Shawn McBroom (OGE) motioned to approve RR270 (OCRTF Revisions to Operating Criteria Appendices). Ron Thompson (NPPD) provided the second. Motion carried unanimously. Agenda Items 11 – Modeling Practice Update Drew McGilvray (SPP) provided an education session on future effective load ownership. See Attachment 25 – Modeling Update_Future Effective Load Ownership Agenda Item 12 –RR252 OOME Enhancement Impact Analysis Erin Cathey presented the Impact Analysis for RR252 (OOME Enhancement). She explained the cost estimate was determined based on development and implementation following completion of the Settlement System Replacement project. The RR252 Impact Analysis was unanimously approved with a ranking of Medium priority. See Attachment 26 – RR252 Impact Analysis and Attachment 27 – RR252 Recommendation Report Motion: Kevin Galke (CUS) motioned to approve the Impact Assessment for RR252 (OOME Enhancement IA) with a Medium rank. John Varnell (Tenaska) provided the second. Motioned carried unanimously.

Agenda Items 13 and 13a – MDRA Historical Data Follow-Up Erin Cathey suggested the MWG defer the discussion to the April MWG meeting to allow stakeholders additional time to analyze the data provided. See Attachment 28 – RR196 Providing MDRA Forecasted Commitments Agenda Item 15 – Regulatory Report Patti Kelly (SPP) presented the regulatory report. She made note of the FERC open meeting on Thursday, February 15th, 2018. Erin Cathey provided an update on SPP’s filing for the 206 Order on Quick-Start Resources from FERC, stating SPP is getting close to a final draft. See Attachment 29 – Regulatory Report February 2018 Agenda Item 16 – Stakeholder Prioritization Terry Rhoades (SPP) provided a refresher on the SPP Stakeholder Prioritization Process. He walked through the different aspects of the process and answered questions. Terry requested stakeholders utilize the SPP RMS to submit additional questions or comments. See Attachment 30 – Stakeholder Prioritization 2018 Agenda Item 17a – MWTG Update Erin Cathey provided an update on the Mountain West Transmission Group (MWTG) revision request review schedule. She explained there are multiple RRs related to the MWTG effort that will be brought to the MWG in March. Debbie James stated the tentative goal is for all MWTG RRs to be complete and provided to the MOPC for review at the July 2018 MOPC meeting. Agenda Item 17b – Reference Bus/LMP Calculation Yasser Bahbaz (SPP) facilitated an education session on the Reference Bus/LMP Calculation design for Mountain West. Taking a step back, Yasser provided some foundational level education to explain the basics of what a reference bus is before explaining why SPP is proposing to use two reference buses for the regions and how SPP envisions the approach operating. Yasser provided examples to illustrate the two reference bus approach. More education on this topic and how SPP will manage the DC Ties will be provided in March prior to the group reviewing MWTG revision requests. See Attachment 31 – MWTG Reference Bus Agenda Item 18 – January MMU Marketplace Update Kevin Bates (SPP MMU) presented the MMU Marketplace Update and answered questions from the group. A stakeholder requested the MMU provide additional detail on Virtual participation. See Attachment 32 – 201801 MWG MMU Market Update Agenda Item 19 – Open Discussion/General Questions Richard Ross provided an opportunity for questions and discussion. Valerie Weigel (Basin) proposed the group plan a future MWG meeting in Denver, CO. Valerie noted Tri-State has offered to host the meeting in their facility at no charge for the meeting space. MWG stakeholders recommended the June/July/August timeframe to meet in Denver. Valerie will work with Erin to finalize logistics and provide an update during the March MWG meeting.

will review the data and provide feedback during the February MWG meeting on the next steps for RR196 (Communicating MDRA Forecasted Commitments). See Attachment 8 – MDRA Update Agenda Item 5 – SPP Culture of Compliance Ben Bright (SPP) provided a brief education session focused on SPP’s Culture of Compliance, specifically highlighting the, “What Does the Tariff Say” (WDTTS) and the “Good Catch” programs. Ben explained SPP staff is encouraged to bring forward any potential issues identified in SPP’s governing documents and that stakeholders can expect to see Revision Requests brought forward from these efforts. See Attachment 9 – Culture of Compliance January 2018 Agenda Item 6a – MWTG Schedule Update David Kelley (SPP) provided an update on the MWTG schedule. David explained that the policies are being discussed and finalized at the Strategic Planning Committee (SPC) and stakeholders will not see draft governing document language for review until the policy direction is set by the SPC. David stated it could be as early as January BOD meeting, but it could also be later. David stated SPP staff is focusing on creating a foundation by providing education to the stakeholders at this time. Erin reminded the group that they will have input as policies progress, through the stakeholder process. Agenda Items 6b and 6c – Day-Ahead Market TCR Funding and ARR/LTCR/ILTCR Obligation John Luallen (SPP) provided high-level training on potential MWTG market design. John covered three cost allocation options; 1) Market-Wide, Regional, and Cross-Regional. Other topics included in John’s training were impacts to charge types, a comparison of the TCR hedge value and TCR hedge funding today versus tomorrow with MWTG. In the second portion of John’s training, he covered the ARR/LTCR/ILTCR obligation proposal. John Luallen (SPP), David Kelley and Gary Cate (SPP) facilitated discussion and answered questions. SPP staff will consider the discussion in future MWTG design development. Jim Flucke recommended this training be provided to the Settlements User Group as well. Details on each topic can be reviewed in the MWTG Settlement Training MWG presentation provided in MWG meeting materials. See Attachment 10 – MWTG Settlement Training MWG Agenda Item 6d – LTCR Counterflow Kevin Galke (CUS) discussed an option to change newly awarded LTCRs to a potential hold requirement, similar to MISO’s construct. Kevin presented the pros and cons of SPP’s existing one year LTCR product with rollover rights and posed several questions to the group before moving into a straw proposal. Kevin facilitated a quick discussion and answered questions. Details on this topic can be reviewed in the LTCR Counterflows presentation provided in the MWG meeting materials. See Attachment 11 – LTCR Counterflows MWG Agenda Item 8 – MOPC Update Jim Flucke provided an overview of the MWG MOPC agenda items. He encouraged the group to discuss agenda items with their MOPC representation prior to the MOPC meeting. See Attachment 12 – MWG MOPC Update

Agenda Items 9, 9a, 9b, 9c, and 9d – NDVER to DVER Conversion Erin Cathey introduced SPP’s draft Revision Request to convert Non-Dispatchable Variable Energy Resources to Dispatchable Variable Energy Resources over a two year transition timeframe. Erin noted the RR would be posted to SPP.org on January 16, 2018 and comments may be officially submitted at that time. Erin, Gary Cate, and Jodi Woods (SPP) facilitated discussion with some individual MWG stakeholders regarding the following:
• Concern of impact to MWTG NDVERs • Desire to have an escalated timeframe for type 3 and 4 wind powered VERs of one year rather
than two years • Desire to include an exception for run-of-the-river hydro not to convert • Desire to include an exception for Type 1 and Type 2 wind powered VERs to have a three year
timeframe rather than the proposed two year timeframe • Desire to require VERs without 100% Firm PTP or NITS service to convert before those with
Firm PTP or NITS service Cliff Franklin (WR) presented details to support RR263 NDVER to DVER Conversion through Incentives. Cliff explained that WR’s approach is a voluntary approach that does not abrogate NDVER PPA contracts and provided examples to illustrate how his proposal would work in production. Cliff facilitated discussion regarding WR proposal and answered questions. Kevin Galke provided an overview of TEA’s comments to RR263 stating that although they appreciate the potential efficiency gains of having more assets dispatchable associated with RR263, they have serious equitability and technical implementation concerns that lead them to oppose the design. Kevin noted the proposal may put NDVER-DCPL at a significant and discriminatory advantage to other resource types in the footprint. Chandler Brown (SEPC) provided an overview of Sunflower’s comments to RR263 stating that Sunflower is supportive of the NDVER to DVER conversion, agrees with the need to respect existing contracts, and agrees that MPs should not be unduly harmed as a result of the conversion. However, Sunflower also stated RR263 may create discriminatory market practices and as such Sunflower does not support the proposal. The MWG will take action on the NDVER to DVER conversion during the February MWG meeting. See Attachment 13 – 2018 Jan 8_Incentive for NDVER Conversion_WR Presentation MWG, Attachment 14 – RR263 NDVER to DVER Conversion Through Incentives, Attachment 15 – RR263 SEPC Comments 010318, Attachment 16 – RR263 CUS Comments 010518, and Attachment 17 – DRAFT RR NDVER DVER Conversion Agenda Items 10, 10a, and 10b – RR252 OOME Enhancement Erin Cathey introduced RR252 (OOME Enhancement) and provided background on past and current status to set the focus for discussion. Erin reminded the group that the Revision Request (RR) had been pulled from Secondary Working Group review when AEP, the RR submitter, and SPP determined there were missing settlement components that were necessary to add. Erin explained the intent of the RR is to
Market Working Group Meeting No. 1 January 8 – 9, 2018
Page 5 of 8
allow Resources operating under an OOME cap and/or floor to be economically dispatched up to and including the newly defined OOME limits. Raleigh Mohr (SPP) expanded on the need for the limits in RR252 SPP Comments. He also specifically noted the need for the distinction between the two types of Out-of-Merit Energy (OOME) presented in RR252. Raleigh walked through other minor clarifying modifications submitted in SPP’s comments. John Luallen (SPP) discussed the two new charge types necessary to implement RR252. After some discussion and modification to RR252 SPP Comments, the group approved unanimously. See Attachment 18 – RR252 SPP Comments 010418, Attachment 19 – RR252 NPPD Comments 112717, Attachment 20 – RR252 MWG Comments 111417, Attachment 21 – RR252 Recommendation Report, and Attachment 22 – RR252 MWG Comments 010818 Motion: Ron Thompson (NPPD) motioned to approve RR252 (OOME Enhancement) SPP Comments as modified by the MWG. Rick Yanovich (OPPD) provided the second. Motion passed unanimously. Agenda Item 11 –RR266 JOU Combined Single Resource Modeling post Settlement Share Allocation Impact Analysis Erin Cathey presented the Impact Analysis for RR266 (JOU Combined Single Resource Modeling post Settlement Share Allocation). Erin explained the cost and duration are estimated based on implementation following the completion of the new settlement system replacement project, which is currently set to be in production during the second quarter of 2019. After discussion, the group requested an additional Impact Analysis for RR266 be performed with the cost and duration estimates based on an implementation that would occur with the new settlement system, rather than after. The group will review both options to determine their desired path. SPP staff will provide the requested information during the February MWG Meeting. See Attachment 23 – RR266 Impact Analysis, Attachment 24 – Severities Levels, Attachment 25 – RR266 Recommendation Report, Attachment 26 – RR260 Repair of RR127, Attachment 27 – RR264 Remove Combined JOU, and Attachment 28 – RR264 AEP Comments 120817 Motion: Cliff Franklin (WR) motioned to approve RR266 (JOU Combined Single Resource Modeling post Settlement Share Allocation) Impact Analysis with a High rank. Jack Madden (ETEC and NTEC) provided the second. Motion withdrawn. Action Item: SPP staff to develop an Impact Assessment for implementation of RR266 (JOU Combined Single Resource Modeling post Settlement Share Allocation) with the new Settlements system for MWG review during the February MWG meeting. Agenda Items 12, 12a, 12b, and 12c – ARR/TCR Process Discussion Deferred to the February 6th-7th MWG meeting. Agenda Item 13 – SPP Market Design Initiative Ranking Erin Cathey summarized the results of the MWG Members’ SPP Market Design Initiative priority ranking. Erin noted that overall the members’ top three priorities are: 1) Multi-Day Unit Commitment, 2) De-Commitment, and 3) Ramp Product. Gary Cate spoke to SPP’s priority ranking and why certain initiatives would be prioritized over, or in conjunction with, others. Gary stated Ramp Product is at the
Market Working Group Meeting No. 1 January 8 – 9, 2018
Page 6 of 8
top of SPP’s list. Nick Parker (SPP MMU) and Keith Collins (SPP MMU) noted support of prioritizing the development of a Ramp Product design. The group requested SPP staff provide, for each initiative, the time commitment to design, the cost and complexity to implement, and the benefits to the market. Erin stated this additional data would be provided during the February MWG meeting. See Attachment 29 – Market Design Initiative Ranking 10-4 Action Item: SPP staff will provide a more detailed scope for each MWG Market Design Initiative which will include; 1) time commitment to design, 2) cost and complexity to implement, and 3) benefits to the SPP Market for MWG review during the February MWG meeting. Agenda Item 14 – FERC Fast-Start Direction & Next Steps Erin Cathey introduced the FERC Fast-Start 206 Investigation, Docket No. EL18-35-000, issued December 21st, 2017. Chris Nolen (SPP) explained the process of a 206 investigation and how it differs from a FERC 205 filing. Chris explained that based on the 206 investigation, FERC has made a preliminary finding that SPP’s Quick Start Resource (QSR) practices may be unjust and unreasonable. Chris informed the group that SPP staff will provide an initial brief to FERC by February 12th, 2018. Gary Cate walked through each of the areas identified by FERC as possibly being unjust and unreasonable, highlighting where the inflight QSR Revision Requests are applicable and where gaps exist. Erin explained how SPP may handle the approved QSR Revision Requests, stating each would be placed on hold until a FERC Order is received. Erin also informed the group that the scheduled stakeholder QSR training and member QSR testing has been cancelled. David Kelley informed members that they have an opportunity to intervene by January 11th. The group held significant discussion regarding the investigation and next steps. SPP’s next steps are to respond to FERC by February 12, 2018. Erin noted that SPP will share the draft response as soon as it is complete. See Attachment 30 – QSR Proposed Market Design, Attachment 31 – EL18-35-000 Fast-Start Order, and Attachment 32 – RR256 Recommendation Report Agenda Item 15 – Multi-Day Minimum Run Time Solution Debbie James (SPP) provided background and explained the purpose of her presentation. Debbie explained the presentation will focus on the two options of which MWG stakeholders requested more information during the November MWG meeting; Option 1 – No MWP after 24 Hours and Option 2 – Binding Offer at Minimum Energy for the Minimum Run Time. Debbie walked through each option in detail and facilitated discussion. Shawn McBroom (OGE) proposed an alternate option where the MWP after 24 hours would become the lesser of the Mitigated Offer or Energy Offer for the balance of the minimum run time. The group discussed and voiced support for OGE’s option. SPP staff will work with Shawn and provide an update during the February MWG. See Attachment 33 – Multi-Day Min. Run Time Gaming Issue_Options Agenda Item 17 – December MMU Marketplace Update Jason Bulloch (SPP) presented the MMU Marketplace Update and answered questions from the group. See Attachment 34 – 201712 MWG MMU Market Update Agenda Item 18 – Regulatory Report

Patti Kelly (SPP) presented the Regulatory Report. Patti brought awareness to FERC’s withdrawal of their proceeding in the Department of Energy’s NOPR on Grid Resiliency Pricing. FERC issued a new order requesting information from RTOs/ISOs in relation to the resiliency of the bulk power system. David Kelley informed the group that the new order will be discussed at the upcoming Strategic Planning Committee (SPC) on January 18th, 2018. See Attachment 35 – Regulatory Report January 2018 Agenda Item 19 – Quarterly Review of all Existing Open Action Items Kristen Darden (SPP) reviewed all existing open action items with the group.

Revision Request Impact Analysis Report
RR #: 266 Date: 1/26/2018
RR Title: JOU Combined Single Resource Modeling post Settlement Share Allocation
Estimated Cost: $389,290 ROM based on information available at the time of the estimate
Estimated Duration: 6 – 8 Months ROM based on information available at the time of the estimate
Primary Working Group Score/Priority: High
SUMMARY OF SYSTEM IMPACTS This RR will impact the following systems: POPS, Markets, and Market Settlements. The changes needed will be reflected in changes to database schemas and system logic. Approximately 50% of the Market Settlements Charge Types may be affected depending upon the design for the changes. There may also be additional charge types required for this RR. Training materials will need to be created once the system design changes are complete. NOTE: This analysis assumes the development will occur with the Settlement Replacement project and that implementation will occur with the new settlement system. See risks noted below in the “SPP Comments” section.

OBJECTIVE OF REVISION REQUEST (as stated in Revision Request Form)
2
The goal of this RR is to address the gaming opportunity and market inefficiencies that currently exist with the JOU market design. The overall intent of this option is to treat the combined JOU as one Resource in the Market clearing decisions by modeling as a single Resource in EMS, AGC and reliability models while performing a percent ownership share allocation split of revenues after the fact. A Designated Asset Owner will submit all JOU data as a single Resource. However, other JOU shares will remain and will be used for settlement purposes; each JOU share will exist only in the context of settlements where final results of clearing are split based on the submitted ownership share percentages to the JOU shares.
Benefits that will be realized from this revision: • Eliminates gaming issues stemming from JOU modeling/logic • Streamlines SPP EMS, ICCP and Market Models • Reduces complexity in both the clearing engine and CR deployment • Removes voltage/VAR issues Maintains ability for the participant to have revenues/charges split out to each share
SPP COMMENTS
SPP recommends a ranking of high. The following are the risks to the Settlement Replacement project if the JOU revision is implemented at the same time: The Settlement Replacement project schedule is very aggressive: Scope –
• Replace and consolidate Market and Transmission billing systems into a single consolidated system • Implementation of non-Protocol impacting enhancements requested by the SUG • Migrate all historic data into new format for replacement system
Testing – • Ensure all results are complete and accurate to current effective Protocol and Tariff • Scenario test with members to validate connectivity and accuracy for pre-defined as well as member specific
scenarios • Parallel test with members in new production environment to validate accuracy and completeness
Risks of introducing member-impacting changes to replacement project:
• Increases scope of replacement project o Even with vendor developed code SPP resource will be diverted from the replacement project to work
with and validate vendor code • Increases magnitude of testing effort for SPP and members
o Scenario testing with JOU logic in effect in a member-facing environment will require members to test their updated shadow settlement systems
o Scenario testing with JOU logic in effect in a member-facing environment will require a coordinated effort across Markets and Settlements
o Parallel testing without JOU logic in effect in the new production environment will require members to test with their current shadow settlement systems
o Even with vendor supported member-facing testing of JOU logic, resource will be diverted from the replacement project to work with the vendor and sign-off on testing
• Implementation of settlement replacement project will require a coordinated effort across Markets and Settlements to implement the JOU logic

The following are the risks to the Settlement Replacement project if the JOU revision is developed with the Settlement system:
• Staff would have to oversee and manage development work with the vendor and could jeopardize the Settlement Replacement project timeline.

SUMMARY OF SYSTEM IMPACTS This RR will impact the following systems: POPS, Markets, and Market Settlements. The changes needed will be reflected in changes to database schemas and system logic. Approximately 50% of the Market Settlements Charge Types may be affected depending upon the design for the changes. There may also be additional charge types required for this RR. Training materials will need to be created once the system design changes are complete. NOTE: This analysis assumes development and implementation will not occur until after the implementation of the Settlement Replacement project.

The goal of this RR is to address the gaming opportunity and market inefficiencies that currently exist with the JOU market design. The overall intent of this option is to treat the combined JOU as one Resource in the Market clearing decisions by modeling as a single Resource in EMS, AGC and reliability models while performing a percent ownership share allocation split of revenues after the fact. A Designated Asset Owner will submit all JOU data as a single Resource. However, other JOU shares will remain and will be used for settlement purposes; each JOU share will exist only in the context of settlements where final results of clearing are split based on the submitted ownership share percentages to the JOU shares.

EXECUTIVE SUMMARY AND RECOMMENDATION FOR MOPC AND BOD ACTION
OBJECTIVE OF REVISION
Background:
SPP introduced Joint Operating Unit (JOU) Resource market design in its Integrated Marketplace Filing (ER12-1179), stating MPs with JOUs may register each ownership share as a separate Resource and then allow the Resource to be offered in the markets and committed and dispatched as separate, individual Resources or committed as a combined Resource and dispatched as individual Resources.
On March 30, 2015, the MMU noted to Market Design an unintended consequence of the JOU Resource design – the “free rider” issue. Two unintended consequences were noted regarding the “combined option” of the JOU design: 1) Free Riders – a Resource that would not have been committed “but for” being part of a JOU. The unit may have an economic minimum output that results in an energy make-whole payment, and 2) Economic inefficiency in the make-whole payment for the start-up and no-load costs when not all parts of the JOU are receiving a make-whole payment. The Market Working Group and SPP staff reviewed nine total potential solutions before moving forward with RR127 (JOU Combined Option - Aggregate Energy Offer Curve) and RR205 Correction to RR127 for Regulation Limit Requirements).
RR127 and RR205 resulted in additional market inefficiencies and more complex gaming opportunities than existed with the original combined JOU Resource market design, so the MWG again began work to determine how best to address the issues with the combined JOU Resource market design.
During the October 2017 MWG meeting, the group reviewed eight total potential solutions. Of the eight solutions, SPP recommended the Market Working Group further pursue discussion and analysis of three viable options; Fully remove the JOU Resource market design (RR248 OGE Submission), Remove only the combined JOU Resource market design (RR248 AEP Comments), and a Single Resource Modeling with Post Market Revenue Allocations to Each Share option (SPP). The MWG rejected the option to remove all JOU Resources design from the SPP market, which rejected all associated comments. A motion was made to direct staff to revert back to pre-RR127 JOU market design, but this motion was postponed to December.
Objectives of Revision Request:
The goal of this RR is to address the gaming opportunity and market inefficiencies that currently exist with the JOU market design. The overall intent of this option is to treat the combined JOU as one Resource in the Market clearing decisions by modeling as a single Resource in EMS, AGC and reliability models while performing a percent ownership share allocation split of revenues after the fact. A Designated Asset Owner will submit all JOU data as a single Resource. However, other JOU shares will remain and will be used for settlement purposes; each JOU share will exist only in the context of settlements where final results of clearing are split based on the submitted ownership share percentages to the JOU shares.
Benefits that will be realized from this revision: • Eliminates gaming issues stemming from JOU modeling/logic • Streamlines SPP EMS, ICCP and Market Models • Reduces complexity in both the clearing engine and CR deployment • Removes voltage/VAR issues • Maintains ability for the participant to have revenues/charges split out to each share

Reason for Abstention:
BEPC (Valerie Weigel) - I want to see the impact assessment on RR266 cost prior to approving. I want to be able to compare that amount to completely removing the combined JOU (RR 264). Tenaska (John Varnell) - I abstained because RR266 did not fix anything for those wanting to self commit.
AEP (Richard Ross) - My abstention on the JOU RR was due to concern over the cost of implementation, but the desire to see a full impact analysis of the approach. However, it is unclear why, if such an approach could be used by selected JOU owners, those owners can not utilize a combined registration option. The legal concerns over coordination that have been expressed would appear to be present in either scenario.

(47)(46) Turn-Around Ramp Rate Factor (a value between 0.01 and 1.00). A Resource’s
ramping direction in the next Dispatch Interval is compared against its ramping direction
in the current Dispatch Interval. If these two ramping directions are different, then the
Turn-Around Ramp Rate Factor is applied to the Dispatch Instruction in the next Dispatch
Interval, except in circumstances where the Resource is selected as available to be cleared
for Regulation or the Resource is being sent an OOME instruction.
The ramping direction in the current Dispatch Interval is based on the actual output at the
beginning of the current Dispatch Interval compared to the Dispatch Instruction at the end
of the current Dispatch Interval. The direction of the next Dispatch Interval is determined
by considering the actual output and ramp capability of the Resource at the time of the
solution and comparing it to the next Dispatch Instruction;

Rate will apply. In the RTBM, if the actual measured MW during deployment is
less than the Breakpoint Limit 1, the Regulation Ramp Rate in Block 1 will apply
back to the actual measured MW.
(b) Block 1 Regulation Ramp Rate – Rate at which a Resource on Automatic
Generation Control can change output in the up and down direction in MW/min at
output levels greater than or equal to Breakpoint Limit 1.
(c) Breakpoint Limit n – Resource MW output at which Regulation Ramp Rate
changes from previous segment values to segment n values.

Ramp Rate submittal is through a segmented profile as follows. Each profile will require
at least one (1) segment and may have up to n segments where n will be defined by SPP,
initially set to ten (10);
(a) Breakpoint Limit 1 – Resource MW output at which segment 1 Contingency
Reserve Ramp Rate will apply. In the RTBM, if the actual measured MW during
deployment is less than the Breakpoint Limit 1, the Contingency Reserve Ramp
Rate in Block 1 will apply back to the actual measured MW.
(b) Block 1 Contingency Reserve Ramp Rate – Rate at which a Resource not on
Automatic Generation Control can change output in the up direction in MW/min
when deploying Contingency Reserve at output levels greater than or equal to
Breakpoint Limit 1.
(c) Breakpoint Limit n – Resource MW output at which Contingency Reserve Ramp
Rate changes from previous segment values to segment n values.
(d) Block n Contingency Reserve Ramp Rate – Rate at which Resource not on
Automatic Generation Control can change output in the up direction in MW/min

Resources using either the Individual Resource Option or the Combined Resource Option as
specified during market registration as described under Section 6.1.6. Otherwise, the Resource is
modeled like any other single Resource with an associated single Asset Owner. Resource offers
may be submitted for each Asset Owner’s JOU ownership (“JOU Share Resource”) the same as
any other Resource subject to the following Resource Offer validation rules and exceptions.
(1) As part of market registration, the following offer parameters representing the ownership
and physical characteristics of the entire JOU (“Physical JOU Resource”) must be
submitted either by or on behalf of the Asset Owner identified at registration (“designated
Asset Owner”):
(a) JOU maximum physical capacity operating limit;
2 Only applicable for the designated Asset Owner identified by the Market Participant that has registered a JOU under the Combined Resource Option (see Section 4.2.2.5.4). A value for each Asset Owner must be submitted by or on behalf of the designated Asset Owner and represents each Asset Owners percentage share of the Physical JOU Resource and must add up to 100%. 3 For Market Participants that have registered a JOU under the Combined Resource Option (see Section 6.1.6.2), this value must be submitted by or on behalf of the designated Asset Owner and represents the value for the entire Physical JOU Resource. See Section 4.2.2.5.4).

(b) JOU Minimum Physical Capacity Operating Limit (Default value. May be updated
as part of the DA Market and RTBM offer. Only required if registered under
Combined Resource Option);
(c) JOU Minimum Physical Regulation Capacity Operating Limit (Default value. May

under Combined Resource Option);
(d)(b) JOU maximum physical 10-minute response from an off-line state (if a
Quick-Start Resource); and
(e)(c) JOU Ownership Percent Share by Asset Owner (Default value. May be updated as
part of DA Market and RTBM Offer. Only required if registered under Combined
Resource Option).
(2) The following Offer parameters as submitted by or on behalf of each Asset Owner for its
JOU Share Resource that have registered under the Individual Resource Option must meet
the following criteria in order to be accepted as valid offers, otherwise, all Offers related
to the Physical JOU Resource will revert to the last valid offer;
(a) The sum of the Maximum Emergency Capacity Operating Limits of each JOU
Share Resource associated with the Physical JOU Resource must be less than or
equal to the Physical JOU Resource maximum physical capacity operating limit.
(3) Commitment of individual JOU Share Resources that have registered under the Individual
Resource Option will be evaluated by SCUC based on the individually submitted Offers
for each JOU Share Resource;
(4) Commitment of a JOU Share Resources that have registered under the Combined Resource
option will be evaluated by SCUC based on a combination of the individually submitted
Resource Offers for each JOU Share Resource and the Offer parameters submitted by or
on behalf of the designated Asset Owner that apply to the entire Physical JOU Resource.
(see Section4.2.2.1 for footnoted parameters to be submitted by or on behalf of the
designated Asset Owner and Section 4.2.2.2 regarding Commitment Status) given the
additional constraint that if one of the JOU Resources is committed, all JOU Share
Resources associated with the Physical JOU Resource must be committed. This rule also

applies to clearing of Supplemental Reserve from an Off-line Quick-Start Supplemental
Reserve Resources. Each Asset Owner of a JOU Share Resource under the Combined
Resource Option must submit a zero for Minimum Emergency Capacity Operating Limit,
Minimum Normal Capacity Operating Limit, Minimum Regulation Capacity Operating
Limit, and Minimum Economic Capacity Operating Limit. The JOU Minimum Physical
Capacity Operating Limit, or Minimum Physical Regulation Capacity Operating Limit
while selected for Regulation, can be achieved by any combination of JOU Share
Resources(s) during the commitment period. The designated Asset Owner of that JOU
under the Combined Resource Option will designate for all shares either the slope or block
option when submitting the Energy Offer Curve. A JOU under the Combined Resource
Option will be dispatched using an aggregated Energy Offer Curve. This aggregated
Energy Offer Curve is made up of all price points from each JOU Share Resource’s Energy
Offer Curve associated with that JOU. When committed, each JOU Share Resource is
eligible for recovery of Start-Up Offer and No-Load Offer costs proportional to that Asset
Owner’s JOU Ownership Percent Share whether or not that JOU Share Resource was
dispatched greater than zero MWs as described under Section 4.5.8.12 and 4.5.9.8. Prior
to evaluation by SCUCFor Make Whole Payment calculation purposes, the Resource Offer
for each JOU Share Resource associated with the Physical JOU Resource is set equal to
the JOU’s Resource Offerassigned the following unit commitment parameters as submitted
by or on behalf of the designated Asset Owner.:
( ) The Start-Up Offer of each Asset Owner’s JOU Share Resource associated with
the Physical JOU Resource is calculated by multiplying the Start-Up Offer
submitted for the Physical JOU Resource by that Asset Owner’s JOU Ownership
Percent Share and this value will be used for Make Whole Payment calculation
purposes;
( ) The Mitigated Start-Up Offer of each Asset Owner’s JOU Share Resource
associated with the Physical JOU Resource is calculated by multiplying the

6.1.6 Jointly Owned ResourceUnit
20
In addition to the responsibilities described under Section 6.1.1, Market Participants wishing to model each ownership share as a separate Resource must choose one of the two options described below and provide the specified additional information. A Resource registered as a Combined Cycle Resource may not register as a JOU.
6.1.6.2 Combined Resource Option Under the Combined Resource Option, the JOU is modeled as one market Resourceeach
ownership share is modeled as a separate Resource for the dispatch purposes but commitment
related parameters are submitted representing the entire physical Resource. Under this option, the
commitment decision is made assuming that all Resource shares must be committed or none at
allfor the Physical JOU Resource. Each Asset Owner of a JOU Share Resource under the
Combined Resource Option must submit a zero for Minimum Emergency Capacity Operating
Limit, Minimum Normal Capacity Operating Limit, Minimum Regulation Capacity Operating
Limit, and Minimum Economic Capacity Operating Limit. The JOU Minimum Physical Capacity
Operating Limit, or Minimum Physical Regulation Capacity Operating Limit while selected for
Regulation, can be achieved by any combination of JOU Share Resource(s) during the
commitment period. The designated Asset Owner of that JOU under the Combined Resource
Option will designate for all shares either the slope or block option when submitting the Energy
Offer Curvesubmit the Resource Offer to be used for commitment, dispatch, and Operating
Reserve clearing. A JOU under the Combined Resource Option will be dispatched using an
aggregated Energy Offer Curve. This aggregated Energy Offer Curve is made up of all price points
from each JOU Share Resource’s Energy Offer Curve associated with that JOU. When committed
each JOU Share Resource is eligible for recovery of Start-Up Offer and No-Load Offer costs
proportional to that Asset Owner’s JOU Ownership Percent Share whether or not that JOU Share
Resource was dispatched greater than zero MWs as described under Section 4.5.8.12 and 4.5.9.8.
This option must be selected if the eligibility criteria stated under the Individual Resource Option
cannot be met. The following additional information must also be provided:
(1) Specification of a single Asset Owner (“designated Asset Owner”) that will be responsible
for submittal by or on its behalf of all unit commitment related datathe Resource Offer and
the following operating data representing the physical operating characteristics of entire
JOU Resource for use in data validation as described under Section 4.2.2.5.4;
21
(2) JOU Maximum Physical Capacity Operating Limit;
(3) JOU Minimum Physical Capacity Operating Limit;
(4) JOU Minimum Physical Regulation Capacity Operating Limit; and
(5)(1) Maximum physical 10-minute response from an off-line state.;
(2) Specification of each Asset Owner, JOU Ownership Percent Share and Settlement Location
associated with each individual ownership share JOU Resource.
(a) Submitted JOU Ownership Percent Shares must add up to 100%.
The default presumption is that the operating owner’s Meter Agent will be the Meter Agent for
that JOU Resource unless each individual JOU Resource owner registers a different Meter Agent
for its share of the Resource.

Attachment AE 1.1 Definitions J Jointly Owned Unit
A Resource that is owned by more than one Asset Owner or a Resource for which multiple Asset
Owners have contractual rights or financial obligations.that allow the submittal of a Resource
Offer into the Integrated Marketplace.
2.2 Application and Asset Registration (1) Applications for a Market Participant to provide services in the Integrated
Marketplace must be submitted to the Transmission Provider prior to the expected
date of participation consistent with Section 6.4 of the Market Protocols.
Applications must conform to the procedures specified in the Market Protocols and
may be rejected if not complete. New Market Participants will follow the timeframe
as specified in Section 6.4 of the Market Protocols in addition to the detailed model
update timing requirements in Appendix E of the Market Protocols.
22
(2) As part of the application process, Market Participants must register all Resources
and load, including applicable load associated with Grandfathered Agreements
(“GFAs”), Non-Conforming Load and Demand Response Load with the
Transmission Provider in accordance with the registration process specified in the
Market Protocols. As part of Resource registration, Market Participants must
specify whether settlement meter data will be submitted on a gross basis or net
basis, where gross meter data does not include reductions for auxiliary load and net
meter data is gross meter data reduced by auxiliary load. Both Non-Conforming
Load and Demand Response Load may only be associated with a single Price Node
except that Non-Conforming Load and Demand Response Load may be associated
with an aggregated Price Node that contains multiple electrically equivalent Price
Nodes. Non-participating embedded load and/or generation must either: (i) register
its load and/or generation in the Integrated Marketplace; or (ii) transfer its load
and/or generation to an external Balancing Authority.
(3) Market Participants may elect to define a single Settlement Location that aggregates
multiple Meter Data Submittal Locations associated with their load assets. Market
Participants may not aggregate multiple Resource Meter Data Submittal Locations
into a single Resource Settlement Location unless the Resources are at the same
physical and electrically equivalent injection point to the Transmission System.
(4) In addition to the responsibilities described in Section 4.1.2 of this Attachment AE
and under the Market Protocols, Market Participants wishing to model each
participant’s share of a Jointly Owned Unit as a separate Resource must choose one
of the two options described below and provide the specified additional
information. A Resource registered as a combined cycle Resource may not register
as a Jointly Owned Unit.
(a) Individual Resource Option
Under the individual Resource option, each participant’s share is
modeled as a separate Resource for the purposes of commitment and,
dispatch and Operating Reserve Clearing, and each Resource may be
committed independent of the other Resource shares.
23
The operating owner’s Meter Agent will be the Meter Agent for that
Jointly Owned Unit unless each individual Jointly Owned Unit participant
registers a Meter Agent for its share of the Resource.
Unless otherwise agreed to by the Jointly Owned Unit participants,
the operating owner will be responsible for submitting the following data:
• Jointly Owned Unit maximum physical capacity operating
limit;
• Jointly Owned Unit minimum physical capacity operating
limit;
• Jointly Owned Unit minimum physical regulation capacity
operating limit; and
• Maximum physical ten (10) minute response from an off-
line state.
(b) Combined Resource Option
Under the combined Resource option, the Jointly Owned Unit is
modeled as one market Resource for the purposes of commitment, dispatch
and Operating Reserve clearing. each participant’s share is modeled and
must be registered as a separate Resource. Under this option, the
commitment decision is made for the JOU Resource assuming that all
Resource shares must be committed or none at all. Each Asset Owner of a
Jointly Owned Unit under the combined Resource option must submit a
zero for the Minimum Emergency Capacity Operating Limit, Minimum
Normal Capacity Operating Limit, Minimum Regulation Capacity
Operating Limit, and Minimum Economic Capacity Operating Limit. The
Jointly Owned Unit minimum physical capacity operating limit and
minimum physical regulation capacity operating limit when the Jointly
Owned Unit is selected to Regulate, can be achieved by any combination of
Jointly Owned Unit shares during the commitment period. A Jointly Owned
Unit under the combined Resource option will be dispatched using an
aggregated Energy Offer Curve. Once committed, each Jointly Owned Unit
share is dispatched independently and is eligible for recovery of Start-Up
24
Offer and No-Load offer costs as described under Sections 8.5.9 and 8.6.5
of this Attachment AE. This option must be selected if the eligibility criteria
stated under the individual Resource option cannot be met.
The operating owner’s Meter Agent will be the Meter Agent for that
Jointly Owned Unit unless each individual Jointly Owned Unit participant
registers a Meter Agent for its share of the Resource.
Unless otherwise agreed to by the Jointly Owned Unit participants,
the operating owner will be responsible for submitting the following data:
• Jointly Owned Unit maximum physical capacity operating
limit;
• Jointly Owned Unit minimum physical capacity operating
limit;
• Jointly Owned Unit minimum physical regulation capacity
operating limit;
• Maximum physical ten (10) minute response from an off-
line state; and
• Participant share percentage by Market Participant.
(5) Market Participants may modify their registered assets in accordance with the asset
registration procedures specified in the Market Protocols.
(6) All loads and all Resources, excluding Behind-The-Meter Generation less than 10
Megawatts (“MWs”), must register. Failure or refusal to register a load will result
in the Transmission Provider filing an unexecuted version of the service agreement
as specified in Attachment AH of this Tariff for that load with the Commission under
the name of the load Asset Owner. Failure or refusal to register a Resource will
result in the Transmission Provider filing an unexecuted version of the service
agreement as specified in Attachment AH of this Tariff for that Resource with the
Commission under the name of the generation interconnection customer under an
interconnection agreement with the Transmission Provider or the applicable
Transmission Owner. In the case of a Qualifying Facility exercising its rights under
PURPA to deliver all of its net output to its host utility, such registration will not
require the Qualifying Facility to participate in the Energy and Operating Reserve
25
Markets or subject the Qualifying Facility to any charges or payments related to the
Energy and Operating Reserve Markets. Any Energy and Operating Reserve
Market charges or payments associated with the output of the Qualifying Facility
will be allocated to the Market Participant representing the host utility purchasing
the output of the Qualifying Facility under PURPA, and the Market Participant will
be provided the settlement data required to verify the settlement charges and
payments.
(7) A Market Participant wishing to Offer an External Resource in the Energy and
Operating Reserve Markets will utilize an External Resource Pseudo-Tie in
accordance with Attachment AO. In addition to the responsibilities outlined in
Attachment AO, the Market Participant registering the External Resource will be
responsible for registering and performing all responsibilities that are required of
Resources in the Energy and Operating Reserve Markets.
(8) A Market Participant wishing to offer Demand Response Load as a Demand
Response Resource in the Energy and Operating Reserve Markets must include in
its application and registration a certification that participation in the Energy and
Operating Reserve Markets by its Demand Response Resource is not precluded
under the laws or regulations of the relevant electric retail regulatory authority.
Consistent with Section 2.8.1 of this Attachment, an aggregator of retail customers
wishing to offer Demand Response Load in the form of a Demand Response
Resource on behalf of one or more retail customers must also include in its
application and registration a certification that participation of each retail customer
is either: (1) not precluded by the laws or regulations of the relevant electric retail
regulatory authority if the customer is served by a utility that distributed more than
4 million MWh in the previous fiscal year; or (2) affirmatively permitted by the
laws or regulations of the relevant electric retail regulatory authority if the customer
is served by a utility that distributed 4 million MWh or less in the previous fiscal
year. Demand Response Resources must meet all application, registration and
technical requirements applicable to the Energy and Operating Reserve Markets.
The Transmission Provider is not responsible for interpreting the laws or
regulations of a relevant electric retail regulatory authority and shall be required
26
only to verify that the Market Participant has included such a certification in its
application materials. The Transmission Provider is not liable or responsible for
Market Participants participating in the Energy and Operating Reserve Markets in
violation of any law or regulation of a relevant electric retail regulatory authority
including state-approved retail tariff(s).
(9) An aggregator of retail or wholesale customers offering Demand Response Load of
one or more end-use retail customers or wholesale customers as a Demand
Response Resource in the Energy and Operating Reserve Markets must be a Market
Participant, satisfying all registration and certification requirements applicable to
Market Participants as well as certification consistent with Section 2.8 of this
Attachment, as required.
(10) All Variable Energy Resources must register as a Dispatchable Variable Energy
Resource except for (1) a wind-powered Variable Energy Resource with an
interconnection agreement executed on or prior to May 21, 2011 and that
commenced Commercial Operation before October 15, 2012 or (2) a Qualifying
Facility exercising its rights under PURPA to deliver its net output to its host utility
or (3) a non-wind powered Variable Energy Resource registered on or prior to
January 1, 2017 and with an interconnection agreement executed on or prior to
January 1, 2017. Variable Energy Resources included in (1) and (3) above may
register as Dispatchable Variable Energy Resources if they are capable of being
incrementally dispatched by the Transmission Provider. A Qualifying Facility
exercising its rights under PURPA to deliver its net output to its host utility may
register as a Dispatchable Variable Energy Resource if it is capable of being
incrementally dispatched by the Transmission Provider and will be subject to the
Dispatchable Variable Energy Resource market rules including Uninstructed
Resource Deviation charges. Any Resource that has previously registered as a
Dispatchable Variable Energy Resource shall not subsequently register as a Non-
Dispatchable Variable Energy Resource.
(11) A Market Participant that is selling firm power to the load asset under a bilateral
contract may, with the agreement of the buyer, register all or a portion of the buyer’s
load as its load asset. For purposes of this Section 2.2(11) of this Attachment AE,
27
the sale of firm power shall refer to power sales deliverable with firm transmission
service, with the supplier assuming the obligation to serve the buyer’s load with
both capacity and energy. For the purposes of Section 2.11.1 of this Attachment
AE, such registration of the buyer’s load by the seller shall be accounted for by
including such load in the seller’s Reported Load and not including such load in the
buyer’s Reported Load, as described under Section 2.11.1(A)(1) of this Attachment
AE, and such associated bilateral contracts shall not be included in either the
buyer’s or seller’s net resource capacity described under Section 2.11.1(A)(4) of
this Attachment AE.

(14) Market Participants with assets interconnected to the Transmission System that are
not participating in the Energy and Operating Reserve Markets must pseudo-tie the
Resource or load out of the SPP Balancing Authority Area in accordance with
Attachment AO. Such assets shall continue to be registered in the Integrated
Marketplace for the purposes of accounting for congestion and loss charges
between the Resource Price Node and the applicable External Interface Settlement
Location as described under Sections 8.6.23 and 8.6.24 of this Attachment AE.
(a) To the extent that the SPP Balancing Authority or associated external
Balancing Authority can no longer maintain the Resource pseudo-tie for
28
reliability reasons, the Market Participant representing the pseudo-tied
Resource must immediately reduce the output of the pseudo-tied resource
to the available pseudo-tie capability after receiving notification from the
affected Balancing Authority of the reduced capability. A Market
Participant shall not generate any energy in excess of the available pseudo-
tie capability after receiving such notification and shall not be compensated
in the Energy and Operating Reserve Markets settlement for any energy
generated in excess of the available pseudo-tie capability.
(15) Western-UGP shall provide to the Transmission Provider the information necessary
to administer the FSE. The required information shall include the following:

the Jointly Owned Unit must be less than or equal to the Jointly Owned Unit
maximum physical capacity operating limit.
Commitment of individual Jointly Owned Unit shares that have registered under the
individual Resource option will be evaluated by security constrained unit commitment
(“SCUC”) based on the individually submitted Offers for each Jointly Owned Unit share.
Under the combined Jointly Owned Unit Resource option, the designated Asset Owner of
the JOU will submit the Resource Offer to be used for commitment, dispatch, and
Operating Reserve clearingthe designated Asset Owner as specified in the Market
Protocols. Commitment of a combined Jointly Owned Unit shares that have registered
under the combined Resource option will be evaluated by SCUC based on a combination
of the individually submitted Resource Offers for each Jointly Owned Unit share and the
commitment related Offer parameterst submitted by the designated Market Participant that
appliesy to the entire Jointly Owned Unit. given the additional constraint that if one of the
Jointly Owned Units is committed, all Resource shares for each Jointly Owned Unit must
be committed. This rule also applies to clearing of Supplemental Reserve from off-line
Quick-Start Resources. Each Market Participant of a Jointly Owned Unit share under the
combined Resource option must submit a zero for Minimum Emergency Capacity
Operating Limit, Minimum Normal Capacity Operating Limit, Minimum Regulation
Capacity Operating Limit, and Minimum Economic Capacity Operating Limit. A Jointly
Owned Unit under the combined Resource option will be dispatched using an aggregated
Energy Offer Curve. When committed, each Jointly Owned Unit share is eligible for
recovery of Start-Up Offer and No-Load Offer costs as described under Sections 8.5.9 and
8.6.5 of this Attachment AE. For Make Whole Payment calculation purposes, the Resource
Offer for each JOU Share Resource associated with the JOU Resource is set equal to the
JOU’s Resource Offer as submitted by or on behalf of the designated Asset Owner and

OBJECTIVE OF REVISION
Objectives of Revision Request: Describe the problem/issue this revision request will resolve.
The current Settlement System contains charge types that are currently not part of RNU processing that result in rounding/residual amounts that have to be manually processed and distributed to remain revenue neutral through Miscellaneous charges. The following proposal would be implemented as part of the new Settlement System scheduled to go live May 2019.
Automate the distribution of rounding/residual issues for the following by incorporating them into the RNU process:
• GFA Daily Distributions – Incorporate GFA Daily Distributions per section 4.5.8.26 of the Protocols into 4.5.12 Revenue Neutrality Uplift Distribution Amount calculation to account for any rounding issues.
• GFA Monthly Distributions – Incorporate GFA Monthly Distributions per section 4.5.8.27 of the Protocols into 4.5.12 Revenue Neutrality Uplift Distribution Amount calculation to account for any rounding issues. The precision is being increased in the share factor to reduce the amount of rounding issues.
• GFA Yearly Distributions – Incorporate GFA Yearly Distributions per section 4.5.8.28 of the Protocols into 4.5.12 Revenue Neutrality Uplift Distribution Amount calculation to account for any rounding issues. The precision is being increased in the share factor to reduce the amount of rounding issues.
• TCR Annual Closeout – Incorporate Transmission Congestion Rights Annual Closeout per section 4.5.8.18 of the Protocols into 4.5.12 Revenue Neutrality Uplift Distribution Amount calculation to account for any rounding issues.
• ARR Annual Closeout – Incorporate Auction Revenue Rights Annual Closeout per section 4.5.10.6 into 4.5.12 Revenue Neutrality Uplift Distribution Amount calculation to account for any rounding issues.
• RNU Residual/Rounding – Incorporate logic to automatically apply any RNU residual amount to the Market Participant with the maximum RNU amount. If multiple Market Participants have the maximum RNU amount, the Market Participant with that max will be selected based on alphabetic order.
Describe the benefits that will be realized from this revision.
The automation of processing will replace manual processing and distribution through Miscellaneous charges.

4.5.8.18 Transmission Congestion Rights Annual Closeout Amount
(1) A DA Market annual credit or charge1 will be calculated for each Asset Owner Transmission Customer with an ARR Nomination Caps established under Section 5.1.3 to the extent that there are any funds remaining once all credits are paid under Section 4.5.8.17. The calculation of the Transmission Congestion Rights Annual Closeout Amount for each Asset Owner with an ARR nomination Cap can result in a residual amounts due to rounding as established under Section 4.5.7. The sum of the residual amounts due to rounding across Asset Owners can result in the Transmission Congestion Rights not being revenue neutral for the year, whether a credit or charge, will be included in the Revenue Neutrality Uplift as established under Section 4.5.12 on the last Operating Day of the planning year. The difference, whether a credit or charge, will be uplifted to the Asset Owners on a yearly basis. On Operating Day March 1, of every year, SPP will uplift the annual residual amount with a Miscellaneous Adjustment to the Asset Owners. The Transmission Congestion Rights Annual Closeout amount is calculated as follows:
#TcrCloseoutYrlyAmt a, yr = (-1) * [ ECFYrlyAmt yr + TcrPaybackSppYrlyAmt yr ]
* ArrNominationCapAoYrlyQty a, yr
/ ArrNominationCapSppYrlyQty yr

4.5.8.27 GFA Carve Out Distribution Monthly Amount
(1) A charge or credit will be calculated at each Settlement Location for each Asset Owner in order for SPP to remain revenue neutral on a monthly basis. Contributors to revenue non-neutrality include:
(a) Reversal of credits to GFA Carve-Outs and FSEs through Monthly TCR Payback and
(b) Reversal of credits to GFA Carve-Outs and FSEs through Monthly ARR Payback;
The amount will be determined by multiplying the Asset Owner monthly determinant by the monthly GFA Carve-Out revenue inadequacy amount. The Asset Owner monthly determinant is equal to the Asset Owner’s monthly real-time load ratio share where such real-time load ratio share excludes GFA Carve Out load and FSE load.
The amount to each applicable Asset Owner is calculated as follows.
#DaGFACarveOutDistMnthlyAmt a, s, mn =
(GFARevInadqcSppMnthlyAmt spp, mn *

4.5.8.28 GFA Carve Out Distribution Yearly Amount
(1) A charge or credit will be calculated at each Settlement Location for each Asset Owner in order for SPP to remain revenue neutral on a yearly basis. Contributors to revenue non-neutrality include:
(a) Reversal of credits to GFA Carve-Outs and FSEs through Yearly TCR Payback;
(b) Reversal of credits to GFA Carve-Outs and FSEs through Yearly TCR Closeout;
(c) Reversal of credits to GFA Carve-Outs and FSEs through Yearly ARR Payback and
(d) Reversal of credits to GFA Carve-Outs and FSEs through Yearly ARR Closeout
The amount will be determined by multiplying the Asset Owner yearly determinant by the yearly GFA Carve-Out revenue inadequacy amount. The Asset Owner yearly determinant is equal to the Asset Owner’s yearly load ratio share where such load ratio excludes GFA Carve Out load and FSE load.
The amount to each applicable Asset Owner is calculated as follows.

4.5.12 Revenue Neutrality Uplift Distribution Amount
(1) A charge or credit will be calculated at each Settlement Location for each Asset Owner for each hour in order for SPP to remain revenue neutral. Contributors to revenue non-neutrality include:
(a) Rounding errors (related to the calculation of all Charges/Credits);
(b) Inadvertent Interchange (as calculated as shown in equation b.3 below);
(c) Joint Operating Agreement Charges/Credits;
(d) RTBM congestion (as calculated as shown in equation b.4 below);
(e) RTBM Regulation Deployment Adjustment;
(f) Make Whole Payments for Out-of-Merit Energy; and
(g) Miscellaneous Charges/Credits.
The amount will be determined by multiplying the Asset Owner hourly determinant by a daily Revenue Neutrality Uplift (RNU) rate. The Asset Owner hourly determinant is equal to the sum that Asset Owner’s actual generation MWh, actual load MWh, actual Interchange Transaction MWh, DA Market cleared Virtual Offer MWh and DA Market cleared Virtual Bid MWh for the Hour, where all of these values are assumed to be positive values.
The calculation of the Revenue Neutrality Uplift (RNU) for each Asset Owner and Settlement Location in the SPP footprint region can result in residual amounts due to rounding as established in Section 4.5.7. The sum of the residual amounts due to rounding can result in SPP not being revenue neutral for the an Operating Day will be uplifted to the Market Participant with the Asset Owner who has the largest daily market activity as defined by summing the hourly determinant established in the previous paragraph across all hours of the Operating Day. The residual amounts for each Operating Day will be summed on a yearly basis. The annual residual amount, whether a credit or a charge, will be uplifted to the Asset Owners and Settlement Locations. On Operating Day March 1 of every year, SPP will uplift the annual residual amount with a Miscellaneous Adjustment to the Asset Owners and Settlement Locations.
The amount to each applicable Asset Owner is calculated as follows.

UPDATE: MOPC Action Item 276: ARR/TSR Firm – Inability to Hedge as Expected -
Parties paying for transmission service are not receiving hedge for congestion cost
In February 2017, the Market Working Group (MWG) was tasked by the Strategic Planning
Committee (SPC) with considering options to improve the process of granting hedges for
congestion, taking into consideration the impacts to existing Transmission Service Rights (TSR)
and Transmission Congestion Rights (TCR) processes. MWG and SPP staff discussed a
substantial amount of analysis throughout the year, as evident from the list provided below in
this summary. As a result of these discussions, the MWG has determined the focus moving
forward is best tuned to reviewing and discussing potential improvements to TCR process
clearing methodologies and counterflow practices, in addition to determining any TCR process
training development that may be beneficial to stakeholders. The list of completed analysis and
discussions are itemized below, as well as the path forward for 2018. All MWG action items
taken throughout 2017 related to the below listed analysis and discussion have been closed.
Over the 2017 year, the MWG reviewed and discussed the following:
• Education on “the differences between the TSR and TCR processes” and “Understanding
the Value of Counterflow”
• Congestion hedging percent by Asset Owner for those who requested their individual
data
• Benefits of the implementation of RR91 during the period of October 2016 through May
2017
o Improved funding
• Cumulative TCR percentages for 3 TCR years
• A duration curve of LTCRs and ARRs requested vs. awarded by path for the last 12
months, excluding round 3, from June 2016 to May 2017
• Analytical comparison of ARR/TCR market performance during the 2015/2016 versus
2016/2017 year
• ARR/TCR Feasibility Study to conduct a least cost study to allocate a higher percentage
of Round 1 ARRs to Firm Transmission using two methods to compare cost; 1) Upgrade
Transmission to allocate ARRs in Round 1 and 2) Unfeasibly grant requested ARRs in
Page 2 of 3
Round 1. The study scope covered June on peak and winter on peak of the 2107-2018
Annual ARR Allocation.
o Study Process Part 1:
1. Determine system limitations that prevent Round 1 ARR requests from
being allocated
2. Identify and model future transmission upgrades that have already
received a notification to construct to mitigate limitations identified in step
1
o Study Process Part 2:
1. Calculate the uplift cost associated with awarding all or a high percentage
of the requested ARRs in Round 1
o Study Process Part 3:
1. Identification of additional transmission upgrades needed and associated
costs
• Value of awarding ARRs in Round 1 of the 2016/2017 TCR year at a 100%, 50%, and
75%
• Identification of Resources that would be available/unavailable for nomination in Round
1 of the ARR process based on a capacity factor breakpoint of 40% and 50% and how the
breakpoints apply to the ARR allocation process
• Total MWs of available candidate ARRs considering the MPs’ nomination caps are based
on their individual capacity factors
• Original total MWs of nominations for the 2017-2018 annual round 1 ARR Allocation
The MWG will focus on the following during the February meeting:
• Eliminating Impact of <3% Impacts from ARR Clearing
• Changing Clearing Methodology to Match TSR Assessment (if proration is based on
impacts)
• Requiring Counterflow Nominations
• TCR related training needs beyond what is offered in SPP’s Learning Management

SECTION 1: INTRODUCTION
SUBSECTION A: PURPOSE, BENEFITS AND BACKGROUND
SPP proposes via RR272 (NDVER to DVER Conversion) to require that, after a two year transition
period, all Variable Energy Resources registered as Non-Dispatchable Variable Energy Resources
(NDVERs) be required to register as Dispatchable Variable Energy Resources (DVERs) unless they are a
Qualified Facility (QF) exercising their rights under the Public Utility Regulatory Policies Act of 1978
(PURPA).
NDVERs in Southwest Power Pool’s (SPP’s) market create market inefficiencies and reliability risks that
SPP resources and systems must mitigated.
1) Market Efficiency: Collections of NDVERs are generally located in the same region, however it
is often necessary to redispatch many Resources (DVERs and others with potentially lower shift
factors) around them in order to solve constraints, leading to higher congestion costs for the
market. Additionally, SPP has observed NDVERs reacting to Locational Marginal Price (LMP)
signals - dropping offline when the LMP drops and responding to increased LMPs by generating
at the same prior output; although by definition, NDVERs are not capable of being incrementally
dispatched by the Transmission Provider. When this price-following behavior from NDVERs
occurs, the subsequent market redispatch and pricing are inefficient, due to the assumption that
NDVERs are not capable of dispatching and reacting to price. Additionally, SPP may issue an
Out-of-Merit Energy (OOME) to NDVERs today. However, the issuance of an OOME is less
precise than the systematic redispatch provided by the market when resources are
dispatchable. This imprecision results in either too much or too little redispatch being provided
requiring other market and reliability mechanisms to make up the difference.
2) Reliability: The price-following behavior of NDVERs also present reliability and operational
challenges when NDVERs suddenly drop offline and then return to follow an increase in LMP as
more relief may be realized than was requested by the Security Constrained Economic Dispatch
(SCED) solution; SCED is unable to effectively clear energy and cover regulation when
NDVERs behave in this manner. This behavior results in the SPP Balancing Authority (BA)
having to manually manage the additional lost output with regulation, putting the Reliability
Coordinator in a position to possibly issue an OOME to the NDVERs who are responding to
LMP changes in order to mitigate flowgates becoming unstable from the unexpected oscillations
caused by NDVERs that follow price. Additionally, NDVERs make up a large majority of the
Southwest Power Pool, Inc.

Resources to which OOMEs are issued. The need to issue an OOME inherently represents an
actual reliability issue that has risen to the attention of the Reliability Coordinator (RC) and
requires the RC to take action to maintain reliability. Although these reliability issues are
manageable, converting NDVERs to DVERs would help to alleviate these reliability risks.
In the 2015 ASOM Report, the SPP Market Monitoring Unit (MMU) stated their concern with NDVERs
due to their adverse impact on market prices. The SPP MMU stated that when prices are depressed in
high wind production regions, NDVERs have an adverse impact on prices in two ways. Some resources
chase price, ignoring the system dispatch and self dispatching to a lower level in an attempt to avoid the
cost associated with producing when prices are very low. This behavior at times causes unexpected
volatility on the system and distorts market prices. The alternative behavior is for these NDVER units to
continue to produce as expected even when prices are below what would be an appropriate market
clearing price. Both cases result in sub-optimal market results. The SPP MMU recommended SPP
transition NDVER Resources to DVER status to lessen the negative impact of such resources on the
market. Work to respond the MMU’s recommendation has been tracked via both the Markets and
Operations Policy Committee (MOPC) and the Market Working Group (MWG) action items.
Benefits of NDVERs converting to DVERs include, but are not limited to:
Increased reliability realized through collective dispatchable Resources mitigating multiple
constraints simultaneously
Increases reliability and economic efficiency through reduction of manual Out-of-Merit Energy
(OOME) instructions
Reduction of price volatility (reliability and economic benefit)
Having more VERs be controllable by the market and not subject only to variable fuel and external
control behaviors leads to less pricing uncertainty as a result of:
Reduction of ramp scarcity events by having NDVERs controllable within SCED
Further optimization of quick start Resource needs by having a larger set of Resources that
are under SCED control
Increased pricing convergence between Day-Ahead and Real-Time due to larger set of
controllable Resources in Real-Time
Further potential optimization of Operating Reserves with potentially more VERs
participating in the offering of certain ancillary services. If they convert, they will be
controllable and may qualify for Regulation-Down
Increased reliability by reducing NDVER generation oscillation

Market efficiencies are gained by adding dispatchable generation to resolve congestion in the
load pocket, rather than redispatching less effective generation to protect the NDVER output;
this has the potential to reduce the congestion costs from less effective generation redispatch

SECTION 3: NDVERS PRICE FOLLOWING
Real-time price-following behavior from NDVERs creates economic inefficiencies and contributes to reliability issues.
Reliability Impacts The most notable impacts to reliability are the sharp changes observed on transmission constraints when NDVERs follow pricing after the SCED dispatch has already been determined. These impacts are not just isolated to the local transmission constraints around the NDVER – they can also have an impact on the redispatch needed to resolve transmission constraints further away as the sharp changes in flows require more redispatch in the RTBM. Outside of the transmission impacts, there are also additional needs for regulation to help maintain control of the SPP BA’s ACE when the NDVERs deviate from expected output much more than standard forecast error. Some examples include
1. Impact to local transmission constraints – As shown in the example charts in the following pages, NDVERs near a flowgate can cause large swings on the transmission constraint which can push the constraint loading over its System Operating Limit (SOL). This often requires remedial action to be taken by operators to either manually redispatch resources (via OOME) of lower the effective limit of a constraint in the RTBM to provide an adequate margin to prevent future SOL exceedances.
2. Additional regulating reserves – Regulating reserves may also need to be deployed to maintain proper control of ACE in the SPP BA, due to the large deviation from expected dispatch for price-following NDVERs. These deviations are typically much larger than standard forecast/persistence error for the RTBM dispatch of NDVERs that are not following prices.
3. Impact to redispatch and control of other transmission constraints – Sharp changes in NDVER output can cause the RTBM SCED to redispatch many resources to provide relief on the transmission constraint. These other resources may also be needed to manage other transmission constraints closer to them, and in times of large swings on the constraint near a price-following NDVER, the SCED may have to solve one constraint at the expense of violating the other constraint due to the relief needed to offset the sharp change in impact from the non-dispatchable resource.
Economic inefficiencies The economic impacts of price-following can also be substantial, ranging from inefficient RTBM dispatch and commitments to extreme price separation and divergences from Day Ahead Market results. Many of the issues stem from the NDVER responding to a real-time price after the dispatch/commitment decisions have already been made.
1. Inefficient dispatch – Since NDVERs are not considered dispatchable by the RTBM SCED, when redispatch is required for a constraint the SCED will use other resources to provide this relief. If the NDVER follows price and moves at the same time as the resources being moved by RTBM, there ends up being more relief provided than necessary, where the SCED could have provide a more optimum solution if the NDVER was allowed to be dispatched.
2. Inefficient commitments – NDVERs are treated as fixed (price takers) at the forecast MW in the RUC studies, so any transmission constraints that NDVERs could be contributing to could also require unit commitments to manage since dispatchable relief cannot be received from the

NDVERs. When the NDVER follows the prices in real-time, it can provide relief on the transmission constraint, which lowers the congestion and lowers the LMPs at the committed resource and makes it uneconomic – in some cases so uneconomic that it was not necessary to be committed. This is similar to the redispatch problem, but instead of getting unnecessary relief from a redispatch, in this case there is unnecessary relief acquired from the commitment of another resource when the more efficient solution would have been to drop output on the NDVER if it was dispatchable. This would ultimately turn into a make-whole payment as the commitment was made from the RUC process but real-time LMPs were not high enough to cover the costs of the resources due to the relief suddenly provided by the NDVER in real-time.
3. Extreme price separation – Sharp swings in constraint loading can cause large ramping requirements for RTBM to meet the relief necessary to bring flowgates under control. This would cause heavy price separation as resources from far away are needed to provide the relief. If there are competing constraints for those same dispatchable resources, those other constraints will see higher shadow prices and drive LMPs apart in those locations as well. In addition to the extreme price separate seen in real-time, these events can also cause price separation across markets (RTBM to Day Ahead), where the sharp changes in real-time are not present in the Day Ahead Market.

Price Following Volatility Example
The example below shows a flowgate loading and an NDVER that is following price. This price-following causes large swings on the transmission system and contributes to the flowgate moving from an unloaded to a loaded state. Additionally, a nearby DVER is being dispatched by RTBM at the same time to resolve the constraint. When we get to real-time both the DVER (following its dispatch set by RTBM) and the NDVER (following the RTBM price) move at the same time. This causes the flowgate loading to drop off sharply. The next RTBM solution begins to reload the DVER (with the assumption that the NDVER will not change significantly), but instead the NDVER ramps up at the same time now that prices have increased. This causes overshoot on the flowgate loading and can contribute to SOL exceedances.

Price Following Volatility Example (continued)
With a further illustration of a similar situation, the chart below shows the smooth control of the transmission constraint during the middle portion of the graph when only the DVER is moving due to RTBM dispatch. Once the NDVER begins following price around the 18:00 time, the flowgate loading begins to swing again and the constraint exceeds its SOL on several occasions.

SECTION 4: INDIVIDUAL NDVER RESOURCE CONVERSION – FINANCIAL ANALYSIS
SPP reran market studies to provide and estimated impact of a single NDVER to DVER conversion. While this analysis will almost invariably show some benefit regardless of the NDVER selection, this only shows one side of the equation and this market analysis is not intended to represent all costs to the resource. SPP only has access to its market and operational information and the offer data provided by the market participant and cannot provide an accurate estimate of the costs, as those costs can vary greatly across resources and requires specific knowledge about the resource.
The selected NDVER was based on a request from a member and was not hand-picked to provide the largest benefit assumption. The analysis is provided here because it has already been completed and SPP believes it not to be an extreme case. However, due to the confidential nature of some of the information, not all of the specifics can be shared, such as resource name, offer prices, nearby transmission constraints, etc. It is important to understand when reviewing the results that this analysis does not claim that the specific resource here is exactly representative of all NDVERs nor that it would represent the full impact if multiple NDVERs were to convert to DVER at the same time. Any costs, benefits, prices, or uneconomic intervals in this example are not intended to apply to all other resources. In terms of total uneconomic intervals experienced for the assumed study period (October 2016 – October 2017), this NDVER was actually on the low end (#85 of 133) of NDVERs.
In terms of a percentage of total energy production for the same time period, the resource was positioned in roughly the same spot relative to other NDVERs (#82 of 133 – first chart below). When using pure energy production (second chart below), the resource ranked higher (#33 of 133).
Southwest Power Pool, Inc.

Looking at the entire NDVER fleet shows that 10% of energy is generated uneconomically (LMP lower than marginal offer price), which translates to an average of 311.6 MW at any given time.

The study was performed using historical market cases to
• Evaluate the effect of treating a single NDVER as a DVER in the Market System
• More importantly to estimate the benefit for the resource if it were treated as a DVER
Southwest Power Pool, Inc.
11
This study used historical RTBM data for two time periods (August and October 2017) to show impacts across peak and off-peak times of the year. The studies were run with the assumption that the NDVER would be converted to DVER, and an additional sensitivity was run varying the ramp rate. The selected resource was not participating in Ancillary Service clearing (DVERs can currently only participate in Regulation Down clearing). Ranges for the analysis were
• A period of time (8/1-8/31) when the LMP was greater than the Marginal Cost. This period would be expected to show the least total benefits due to higher LMPs during the summer months.
• A period of time (10/1-10/14) when the LMP was less than the Marginal Cost. . This period would be expected to show the most total benefits due to lower LMPs during the shoulder months.
For the studied time periods, the benefits were quantified as the difference in resource revenue received from Dispatch times LMP (divided by 12 to account for 5-minute interval length of RTBM). While many days and intervals were analyzed, benefits were only calculated for as the difference in revenues for intervals where the resource LMP was less than the resource marginal offer price.
The three scenarios studied during the above time range were
• Baseline – The resource stays as NDVER and the studies are re-run using the simulated dispatch • DVER – The resource is converted to DVER and participates in energy dispatch during the
simulation using a 1 MW/min ramp rate • DVER +8 – The resource is converted to DVER and participates in energy dispatch during the
simulation using an 8 MW/min ramp rate
A baseline scenario was needed (that was a simulation as well) to provide the basis for the calculations and remove the impact of any potential differences between historical results and the simulation. The total number of intervals analyzed were over 10,000 across the two study periods and all scenarios were run through the same intervals.

Savings for the simulations during intervals where the resource LMP was less than the resource marginal offer price were $17.82 per interval in the DVER scenario (relative to the Baseline) and $21.64 per interval in the DVER+8 scenario (relative to the Baseline). This difference between scenarios (higher benefits with higher ramp rates) is expected because the converted DVER would be allowed to be curtailed faster when uneconomic and reloaded faster when economic if the DVER had a higher ramp rate.

SECTION 5: WIND-POWERED DVER TYPE I AND II OPERATIONAL OPTION
SUBSECTION A: TYPE I AND II INTERIM PROPOSAL
Type I and II wind turbines may not be able to follow a five-minute Setpoint instruction without a large capital investment and communication and control overhaul. This subsection helps describe that a wind NDVER with physical Type I or II turbines may reregister as a DVER, and leverage existing market offer optionality as an alternative.
Note: The Southwest Power Pool Reliability Coordinator (RC) recommends that all Resources follow Setpoint Instructions as indicated by the Real-Time Balancing Market (RTBM) Security Constrained Economic Dispatch (SCED) engine. These signals are used to maximize efficiency, while maintaining reliability of the bulk electric system. If there are legitimate reasons any Resource may not follow the Setpoint Instructions, the Resource, inclusive of run-of-river hydroelectric and Type I and II wind turbines, may elect to submit a Control Mode Status 3, which will allow the RTBM study to echo the Resource’s SCADA. It is strongly recommended that Control Mode Status 3 be leveraged only when that Resource does not have the ability to follow the market offer-based SCED instruction.
Proposal:
• Use offer curve of blocked - this means all MWs between the blocks are priced the same.
• Submit a Ramp Rate profile that equals each block of offer curve
• Except in periods where the Resource is marginal, this allows for dispatch down to be based on
logical groupings of turbines that are either on or off
• Note that this option is available to any NDVER today
Pros
• Defacto block dispatch for a VER
• Allows dispatch possibility without hardware/software upgrades
Cons
• If marginal, dispatch could be between the blocks
o Uninstructed Resource Deviation (URD) exposure can be mitigated by block size
• Operationally, if between blocks, SPP is sending signal that the Resource might not meet
Southwest Power Pool, Inc.

o Based on block size, this is better than any current NDVER, where there is no
dispatchability at all

OBJECTIVE OF REVISION
Page 3 of 6
Objectives of Revision Request: Describe the problem/issue this revision request will resolve.
SPP proposes in this revision request to require that, after a two year transition period, all Variable Energy Resources registered as Non-Dispatchable Variable Energy Resources be required to register as Dispatchable Variable Energy Resources unless they are a Qualified Facility exercising their rights under the Public Utility Regulatory Policies Act of 1978 (PURPA).
Non-Dispatchable Variable Energy Resources in SPP’s market create market inefficiencies and reliability risks that SPP resources and systems must mitigated.
1) Market Efficiency: Collections of NDVERs are generally located in the same region, however it is often necessary to redispatch many Resources (DVERs and others with potentially lower shift factors) around them in order to solve constraints, leading to higher congestion costs for the market. Additionally, SPP has observed NDVERs reacting to LMP signals - dropping offline when the LMP drops and responding to increased LMPs by generating at the same prior output; although by definition, NDVERs are not capable of being incrementally dispatched by the Transmission Provider. When this price-following behavior from NDVERs occurs, the subsequent market redispatch and pricing are inefficient, due to the assumption that NDVERs are not capable of dispatching and reacting to price. Additionally, SPP may OOME NDVERs today. However, the issuance of an OOME is less precise than the systematic redispatch provided by the market when resources are dispatchable. This imprecision results in either too much or too little redispatch being provided requiring other market and reliability mechanisms to make up the difference.
2) Reliability: The price-following behavior of NDVERs also present reliability and operational challenges when NDVERs suddenly drop offline and then return to follow an increase in LMP as more relief may be realized than was requested by the SCED solution; SCED is unable to effectively clear energy and cover regulation when NDVERs behave in this manner. This behavior results in the SPP BA having to manually manage the additional lost output with regulation, putting the Reliability Coordinator in a position to possibly issue an OOME to the NDVERs who are responding to LMP changes in order to mitigate flowgates becoming unstable from the unexpected oscillations caused by NDVERs that follow price. Additionally, NDVERs make up a large majority of the Resources to which OOMEs are issued. The need to issue an OOME inherently represents an actual reliability issue that has risen to the attention of the RC and requires the RC to take action to maintain reliability. Although these reliability issues are manageable, converting NDVERs to DVERs would remove the associated reliability risks.
In the 2015 ASOM Report, the SPP MMU stated their concern with Non-Dispatchable Variable Energy Resources due to their adverse impact on market prices. The SPP MMU stated that when prices are depressed in high wind production regions, NDVERs have an adverse impact on prices in two ways. Some resources chase price, ignoring the system dispatch and self dispatching to a lower level in an attempt to avoid the cost associated with producing when prices are very low. This behavior at times causes unexpected volatility on the system and distorts market prices. The alternative behavior is for these NDVER units to continue to produce as expected even when prices are below what would be an appropriate market clearing price. Both cases result in sub-optimal market results. The SPP MMU recommended SPP transition NDVER Resources to DVER status to lessen the negative impact of such resources on the market. Work to respond the MMU’s recommendation has been tracked via both MOPC and MWG action items.
Describe the benefits that will be realized from this revision.
Increased reliability realized through collective dispatchable Resources mitigating multiple constraints simultaneously Increased economic efficiency through reduction of manual Out-of-Merit Energy (OOME) instructions Reduction of price volatility (reliability and economic benefit) Having more VERs be controllable by the market and not subject only to variable fuel and external control behaviors leads to
less pricing uncertainty as a result of: Reduction of ramp scarcity events by having NDVERs controllable within SCED Further optimization of quick start Resource needs by having a larger set of Resources that are under SCED control Increased pricing convergence between Day Ahead and Real-Time due to larger set of controllable Resources in RT Further potential optimization of Operating Reserves with potentially more VERs participating in the offering of
certain ancillary services. If they convert, they will be controllable and may qualify for REG DN Increased reliability by reducing NDVER generation oscillation Market efficiencies are gained by adding dispatchable generation to resolve congestion in the load pocket, rather than
redispatching less effective generation to protect the NDVER output. This has the potential to reduce the congestion costs from less effective generation redispatch

OBJECTIVE OF REVISION
Objectives of Revision Request: Describe the problem/issue this revision request will resolve.
SPP proposes in this revision request to require that, after a two year transition period, all Variable Energy Resources registered as Non-Dispatchable Variable Energy Resources be required to register as Dispatchable Variable Energy Resources unless they are a Qualified Facility exercising their rights under the Public Utility Regulatory Policies Act of 1978 (PURPA).
Non-Dispatchable Variable Energy Resources in SPP’s market create market inefficiencies and reliability risks that SPP resources and systems must mitigated.
1) Market Efficiency: Collections of NDVERs are generally located in the same region, however it is often necessary to redispatch many Resources (DVERs and others with potentially lower shift factors) around them in order to solve constraints, leading to higher congestion costs for the market. Additionally, SPP has observed NDVERs reacting to LMP signals - dropping offline when the LMP drops and responding to increased LMPs by generating at the same prior output; although by definition, NDVERs are not capable of being incrementally dispatched by the Transmission Provider. When this price-following behavior from NDVERs occurs, the subsequent market redispatch and pricing are inefficient, due to the assumption that NDVERs are not capable of dispatching and reacting to price. Additionally, SPP may OOME NDVERs today. However, the issuance of an OOME is less precise than the systematic redispatch provided by the market when resources are dispatchable. This imprecision results in either too much or too little redispatch being provided requiring other market and reliability mechanisms to make up the difference.
2) Reliability: The price-following behavior of NDVERs also present reliability and operational challenges when NDVERs suddenly drop offline and then return to follow an increase in LMP as more relief may be realized than was requested by the SCED solution; SCED is unable to effectively clear energy and cover regulation when NDVERs behave in this manner. This behavior results in the SPP BA having to manually manage the additional lost output with regulation, putting the Reliability Coordinator in a position to possibly issue an OOME to the NDVERs who are responding to LMP changes in order to mitigate flowgates becoming unstable from the unexpected oscillations caused by NDVERs that follow price. Additionally, NDVERs make up a large majority of the Resources to which OOMEs are issued. The need to issue an OOME inherently represents an actual reliability issue that has risen to the attention of the RC and requires the RC to take action to maintain reliability. Although these reliability issues are manageable, converting NDVERs to DVERs would remove the associated reliability risks.
In the 2015 ASOM Report, the SPP MMU stated their concern with Non-Dispatchable Variable Energy Resources due to their adverse impact on market prices. The SPP MMU stated that when prices are depressed in high wind production regions, NDVERs have an adverse impact on prices in two ways. Some resources chase price, ignoring the system dispatch and self dispatching to a lower level in an attempt to avoid the cost associated with producing when prices are very low. This behavior at times causes unexpected volatility on the system and distorts market prices. The alternative behavior is for these NDVER units to continue to produce as expected even when prices are below what would be an appropriate market clearing price. Both cases result in sub-optimal market results. The SPP MMU recommended SPP transition NDVER Resources to DVER status to lessen the negative impact of such resources on the market. Work to respond the MMU’s recommendation has been tracked via both MOPC and MWG action items.
Describe the benefits that will be realized from this revision.
Increased reliability realized through collective dispatchable Resources mitigating multiple constraints simultaneously Increased economic efficiency through reduction of manual Out-of-Merit Energy (OOME) instructions Reduction of price volatility (reliability and economic benefit) Having more VERs be controllable by the market and not subject only to variable fuel and external control behaviors leads to
less pricing uncertainty as a result of: Reduction of ramp scarcity events by having NDVERs controllable within SCED

redispatching less effective generation to protect the NDVER output. This has the potential to reduce the congestion costs from less effective generation redispatch
COMMENTS
NPPD has concerns with RR272
See below for NPPD comments related to RR272:
- SPP has stated that conversion of the NDVER to DVER units would have a positive impact on market efficiencies. With a potential of market benefits, we believe it to be short sighted to not address the cost impacts of such a conversion on the member utilities. This would include a process to determine the level of cost by that Entity and have the market compensate the costs.
- There are some Resources not designed to move every 5 minutes. Example would be Type 1 and Type 2 wind turbines. Converting these types of Wind Turbines would likely result in additional maintenance costs and increased risk of turbine failures. These costs and risks will be borne by the member or developer with potentially no chance of cost recovery from SPP.
- Generally speaking, there is a broader issue that should be addressed. And that is the lack of market systems recognizing that there are a number of generating units that have connected to the SPP system utilizing only a Generator Interconnect Agreement (GIA). The SPP Tariff has historically allowed this type of service, but the market needs to be able to recognize that these units are essentially utilizing non-firm transmission and being dispatched comparatively to units that have requested, and paid for, firm transmission service. Most NDVER’s have requested and paid for upgrades to get firm transmission for delivery to their load. The Firm Transmission Rights allow a hedge however that still is not enough to offset the impacts of resources not having Firm Transmission Rights. Also getting the congestion rights needed, are at times, not possible even if having firm transmission rights. If SPP could differentiate between these types of resources and dispatch those non-firm resources that are impacting the congestion before prices become volatile that would result in a better overall market. At this time there is not much in enhancement of acquiring Firm Transmission by resources. If SPP would curtail resources without firm transmission before those with Firm it could enhance more firm transmission being requested and upgrades that the costs are currently borne by the Load.
- The SPP Market sees many periods of price spikes in the RT Market due to flowgate congestion. At what level of a price spike due to a CME event is a Reliability Signal? NPPD believes that there are times that when flowgates are “Binding” or “Breached” and flows need to change address reliability concerns it should be a Reliability Signal. The reason for the price spikes is due to a current or projected transmission line overload or N-1 condition. That is a reliability concern and that signal should be treated that way. NPPD has asked for a clarification on this subject from SPP and has yet to see a response.
- Additionally, this is an example of SPP changing the market rules which were agreed upon during the SPP IM integration phase. SPP allowed the use of NDVERs and now that agreement is potentially changing with the added cost burden of the changes being placed on the member utilities.

OBJECTIVE OF REVISION
Objectives of Revision Request:
Describe the problem/issue this revision request will resolve.
SPP proposes in this revision request to require that, after a two year transition period, all Variable Energy Resources registered as
Non-Dispatchable Variable Energy Resources be required to register as Dispatchable Variable Energy Resources unless they are a
Qualified Facility exercising their rights under the Public Utility Regulatory Policies Act of 1978 (PURPA).

COMMENTS
Westar has concerns with RR272:
Westar agrees with the NPPD comments listed at the bottom of this document but would add several considerations not addressed
by SPP staff in RR272.
- First and foremost, SPP staff has repeatedly communicated their desire to make NDVER dispatchable, either through
dispatch instruction NDVER clips, RR272, or in MWG discussions on wind. They state that price-following
NDVERs have caused significant reliability issues since the start of Integrated Marketplace (IM) in 2014. If price-
following NDVERs are the real problem, then at a minimum, SPP staff should have submitted an option for MWG
consideration to penalize price-following NDVERs instead of forcing all NDVER conversions as in RR272.
- SPP provides a presentation 8.a.NDVER to DVER Conversion Analysis.pdf claiming there have been reliability issues
associated with price following NDVERs and there exists significant market efficiency benefits to be gained in forcing
NDVER to DVER conversion. There is no study, nor does it include financial impacts forced upon NDVER
owners/buyers in making conversions. The presentation states “78% of NDVERs have Firm PTP/Firm NITS” but fails
to acknowledge that the market dispatch provides no recognition of this fact. In fact, this RR fails to recognize the fact
that it is the interconnection process that has allowed additional generation to be connected to the grid creating existing
generation NDVERs to become congested and now look for the NDVER party to financially remedy this short coming
in market design. In SECTION 4: INDIVIDUAL NDVER RESOURCE CONVERSION – FINANCIAL ANALYSIS,
SPP states, “The annual savings ranged from $94k to $115k” for a single NDVER to DVER conversion. We can
assess nothing from this analysis. Was the unit the most constrained NDVER or was it truly a representation of the
average. Someone once said that you can twist the arm of statistics/modeling until they confess to anything. SPP fails
to provide critical information needed to make their analysis credible;
1. What was the name and location of the NDVER resource?
2. What was the size in MW of the NDVER resource and was it representative of all NDVERs?
3. Is SPP claiming 5000 intervals where NDVER offers fall below LMP representative of all SPP NDVERs and
is it necessary to achieve positive economics and is it representative of all NDVERs?
4. Do NDVERs having less than 5000 intervals where their offer fell below the LMP not benefit from a NDVER
conversion?
5. What transmission constraints were applicable to the study NDVER and was it representative of all NDVERs?
6. How many hours of negative pricing were experienced by this resource and is it representative of all
NDVERs?
7. During high wind and low load intervals, what was the bottom standard deviation LMP pricing and was it
representative of all NDVERs?
8. Did SPP re-price SCED dispatch for both the NDVER, NDVER→DVER conv, DVER, DVER+8 or did SPP
staff just add subtract NDVER/DVER scenarios assuming historical LMPs would not change?
9. What transmission constraints were applicable to the study NDVER and was it representative of all NDVERs?
10. Would conversion of all NDVERs reduce benefits for the study NDVER if SPP completely re-priced all SPP
LMP locations?
11. Is 10/2016 – 10/207 representative of wind and wind/generation mix since market startup or did that time
frame contain higher wind values that historically seen in SPP?

- RR272 effectively abrogates all NDVER PPA contracts, except for qualifying facilities, by undermining the
grandfathered non-dispatchable status over older wind farms upon which their supply contracts were based. RR272
fails to address the financial exposure of owners/buyers of NDVERs by forcing them to become dispatchable which
they may be incapable to perform within URD guides and which their contracts lacked notice to consider. RR272
throws NDVER owners/buyers “under the bus” by financially exposing them “economic dispatch” of which neither
contract accounted for nor the unit was operationally constructed. RR272 forces NDVER conversion and abrogates
NDVER contracts making RR272 unjust and unreasonable.
- RR272 fails to address the issue that many Market Participants (MPs) manage many NDVERs in the market owned by
an Asset Owner which is not an MP. SPP puts the burden of NDVER conversions completely onto MPs which may
not own the NDVER nor have any control over upgrades for the resource. Likewise, in cases where NDVERs
capacity/energy is sold from AO seller to MP buyer, RR272 places all burden of NDVER conversion to the buyer MP
in which RR272 has no regard for their inability or lack of authority to make NDVER→DVER upgrades. This will
leave the buyer MP in a badly disadvantaged position to renegotiate unit upgrades and contract terms, likely resulting
in significant financial loss exposure. RR272 lack of consideration for NDVER financial exposure to make them
dispatchable is clearly unjust and unreasonable. RR272, at minimum, should be changed to make Generation
Interconnection Owners have the burden of upgrading NDVERs.
- Last and perhaps the most import factor not considered by RR272 is SPP’s market reputation. NDVERs were a
condition of several MPs agreeing to transition from EIS to IM. If we go back on our word, will other MPs lose
confidence in the stability of SPP tariff grandfathering and agreements made to prospective Balancing Authorities,
Asset Owners, and Market Participants considering the benefits of join SPP as a stable settlement & market platform?

OBJECTIVE OF REVISION
Objectives of Revision Request: Describe the problem/issue this revision request will resolve.
This RR provides to MWG a true incentive “carrot” for a Non-Dispatchable Variable Energy Wind Resource (NDVER) to have the option to voluntarily upgrade their wind farm dispatch controls so SPP can curtail NDVERs for non-emergency events based upon a follow dispatch flag and a 5-minute dispatch signal. NDVERs could then voluntarily allow SPP to curtail their output for non-emergency events such as;
1. economic dispatch,
2. helping to relieve binding constraints,
3. helping reduce system capacity during Minimum Generation events, or
4. helping relieve SPP regulation up/down ramping deficiencies.
PPA contracts were formed by NDVER owning Market Participants (MPs) assuming the SPP Integrated Marketplace would continue to grandfather older wind farms built prior to 10/15/2012 and not be forced into being economically dispatchable. It was one of the requirements for some to MPs to join SPP EIS and IM markets. FERC agreed with the SPP 10/15/2015 compromise, by approving tariff language and not requiring some older wind farms to be dispatchable.
Some recent proposals by SPP advocate making all NDVERs dispatchable, regardless of upgrade or PPA cost exposure imposed onto NDVER owner/buyers. Thus, SPP proposes abrogating all previously negotiated NDVER PPA contracts, forcing the NDVER sellers/buyers into PPA renegotiation, or the more likely outcome, owners/buyer financial losses.
However, this RR proposes incentives for MP NDVER owners to upgrade their controls, requires the market to pay NDVER wind farms, optionally choosing dispatchable control status, to be paid for their curtailment according to the buyers PPA contract financial exposure by reimbursing wind owners for lost federal government PTC revenues and does not financially abrogate grandfathered NDVER PPA contracts between sellers/buyers.
Describe the benefits that will be realized from this revision.
Contrary to the “stick” approaches previously proposed by SPP staff or stakeholders, the RR offers SPP & MWG a legitimate “carrot” approach to incent NDVERs to voluntarily become dispatchable. This RR proposes that LMPs and MCPs be formulated to compensate NDVERs for the lost PTC and PPA rate (if contractually applicable) into both local LMPs & MCPs, as a type of SPP DRR payment. This type of DRR payment will be known as a Dispatch Curtailment Pseudo Load (NDVER-DCPL). The NDVER-DCPL placed at the renewable resource location (e.g. Non-dispatchable NDVER wind, solar, storage, hydro, etc.) can submit a NDVER-DCPL offer curve which will be settled at the renewable curtailed output at the negative LMP at an electrically equivalent output location to the NDVER output terminals.
For the example above, Windfarm A is an NDVER voluntarily registering a NDVER-DCPL, will be paid according to the curtailed output of the NDVER.

Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load – (NDVER-DCPL)
After a Market Participant (MP) has upgraded a Non-Dipatchable Variable Energy Resource (NDVER) to accept 5-minute economic/reliability dispatch instructions from SPP, the MP may register a Dispatch Curtailment Pseudo Load NDVER-DCPL so the MP can be paid by SPP for NDVER curtailments without SPP having to issue an OOME instruction. The NDVER-DCPL will represent a MP capacity/price offer for SPP to using in clearing curtailment NDVER MWs.. During emergencies or reliability issues which SCED can’t solve, SPP shall continue to issue OOME instructions to NDVERs.
SPP shall clear NDVER-DCPL curtailment MWs for the NDVER using the negated NDVER LMPi.. SPP shall settle the NDVER-DCPL based NDVER curtailed MWs at a negated NDVER LMPi or negated NDVER MCP price based upon the NDVER-DCPL offer curves. Self or curtailment more than SPP dispatch instructions will not be cleared by SPP.

4.5.3.4 GFA Carve Out or FSE Uplift
GFA Carve Out or FSE Schedules result in removal of the energy, congestion, and marginal losses for the transaction from settlement statements. SPP will capture the congestion charges and marginal loss charges related to the GFA Carve Outs or FSEs. These charges will be offset by the ARR/TCR settlement that would have been claimed for the GFA Carve Out or FSE
Page 4 of 27
under the normal ARR/TCR process and the distribution of the Marginal Loss Overcollection funds. Candidate ARRs associated with the GFA Carve Out or FSE service shall not be nominated for a product period if, based upon the twelve preceding months for which congestion data is available, such ARR, had it been converted to a TCR, would have resulted in a TcrFundHrlyAmt net charge to the holder of the TCR over that product period, as defined for the annual ARR allocation process. However, until twelve months of Integrated Marketplace data is available, SPP will use relevant data from both the EIS Market and the Integrated Marketplace to estimate whether the result is a net charge.
(i) For the MW capacity associated with each FSE, the sink for the ARR/TCR shall be the (1) load Settlement Location within the UMZ, (2) interface with an external Balancing Authority, or (3) FSE Transfer Point, as appropriate. For ARR/TCR activity from FSE Transfer Points to load external to the UMZ but internal to the Transmission Provider, the normal ARR/TCR process is available to the applicable Market Participants from the FSE Transfer Point to the load consistent with the transmission service reservation.
4.5.4 Calculation of LMPs, LMP Components and MCPs
SPP uses a co-optimized SCED model to compute Locational Marginal Prices (LMPs) for Energy at PNodes. The LMPs are then mapped to Settlement Locations in the commercial model. The SCED model also computes Market Clearing Prices (MCPs) for Regulation-Up Service, Regulation-Up Mileage, Regulation-Down Service, Regulation-Down Mileage, Spinning Reserve and Supplemental Reserve on a Reserve Zone basis. For the DA Market, LMPs and MCPs are calculated on an hourly basis. For the RTBM, LMPs and MCPs are calculated for each 5-minute Dispatch Interval. Inputs to SCED for the DA Market are as described under Section 4.3.1.1 and inputs to SCED for the RTBM are as described under Section 4.4.2.2. The following subsections further describe how LMPs, LMP Components and MCPs are calculated.
4.5.4.1 LMP Calculations and LMP Components
The LMP at a PNode is the cost of delivering an incremental MW of energy at that specific PNode, while satisfying all operational constraints where such cost will include applicable Demand Curve prices if the incremental MW of energy causes a corresponding increase in shortage conditions where such Demand Curve prices and shortage conditions are as described under Section 4.1.5. The LMP at any PNode is the sum of three components; the marginal costs of Energy (Marginal Energy Component or MEC), the marginal cost of losses (Marginal Loss Component or MLC), and the marginal cost of congestion (Marginal Congestion Component or MCC).
LMP Components at PNode i are calculated based upon the following formulas:
LMPi = MEC + MLCi + MCCi
Where:
(1) MEC is the component of LMPi representing the marginal cost of Energy;
Page 5 of 27
(2) MLCi is the component of LMPi representing the marginal cost of losses at PNode i relative to the Reference Bus;
(3) MCCi is the component of LMPi representing the marginal cost of congestion at ENode i relative to the Reference Bus; and
(4) The Reference Bus represents the network Distributed Load Bus.
(5) NDVER-DCPL curtailment load locations are always linked to a NDVER resource. The NDVER-DCPL LMP shall be the negative of the linked NDVER LMP where,
NDVER-DCPLk LMPi = (NDVERk LMPi ) ( -1 )
4.5.4.1.1 Marginal Losses Component Calculation
The MLCi at each PNode i is defined by the following equations:
MLCi = -MLSFi * MEC
MLSFi = ∂ (SPP Losses) / ∂ Pi
Where:
(1) SPP Losses = SPP transmission system losses;
(2) MLSFi = Marginal Loss Sensitivity Factor at PNode i;
(3) MEC is the component of LMPi representing the marginal cost of Energy;
(4) Pi = Net injection at PNode i.
(4)(5) NDVER-DCPL pseudo load will not be considered within MLCi since it represents a curtailment of NDVER generation and does not represent actual physical load.
The MLSFi is a linearized estimate of the change in SPP transmission losses that will result from a 1 MW injection at PNode i coupled with a corresponding withdrawal at the Reference Bus to maintain global power balance (the withdrawal at the Reference Bus will generally be higher or lower than 1 MW since there will be a change in losses). Marginal loss sensitivity factors are dependent on topology, node injections and node withdrawals, and are only considered constant within a small deviation from a fixed operating point.
4.5.4.1.2 Marginal Congestion Component Calculation
The MCC at each PNode i is defined by the following equations
MCCi = - ( ∑=
K
k 1Sensik * SPk )
Sensik = ∂ Flowk / ∂ Pi
Where:
Page 6 of 27
(1) K is the number of transmission constraints;
(2) Sensik is the linearized estimate of the change in the constraint k flow resulting from an incremental energy injection at PNode i coupled with an incremental energy withdrawal at the Reference Bus;
(3) Flowk = Calculated flow for constraint k;
(4) SPk = is the Shadow Price of constraint k;
(5) Pi = Net injection at PNode i.
4.5.4.1.3 Marginal Energy Component Calculation
The MEC is defined as the computed LMP at the Reference Bus. By definition, MCC and MLC components are zero at the Reference Bus.
4.5.4.2 MCP Calculations
The MCP represents the cost of supplying an increment of operating reserve, taking into account lost opportunity cost and is composed of the marginal Operating Reserve costs and marginal costs associated with Operating Reserve scarcity. The DA Market and RTBM MCPs for Regulation-Up Service, Spinning Reserve and Supplemental Reserve at a Reserve Zone for Resources with cleared Regulation-Up Service, Spinning Reserve and/or Supplemental Reserve at that Reserve Zone are equal to the summation of the applicable Shadow Prices associated with each Operating Reserve constraint. This type of MCP formulation is referred to as “price-cascading”. MCPs applied to Excess Regulation-Up Mileage, Unused Regulation-Up Mileage. Excess Regulation-Down Mileage and Unused Regulation-Down Mileage are calculated for the RTBM only as described in (2) and (3) below.
(1) There are four sets of constraints: (i) an Operating Reserve constraint which is set equal to the sum of the Contingency Reserve requirement and the Regulation-Up requirement; (ii) a Regulation-Up Service plus Spinning Reserve constraint which is set equal to the sum of the Regulation-Up requirement and the Spinning Reserve requirement; and (iii) a Regulation-Up Service constraint which is set equal to the Regulation-Up requirement; and (iv) a Regulation-Down Service constraint which is set equal to the Regulation-Down requirement. These constraints apply on both a system-wide basis and a Reserve Zone basis. MCPs for each Reserve Zone are calculated as follows:
(a) The zonal Regulation-Up Service MCP is equal to sum of the system-wide and zonal Shadow Prices for the Regulation-Up constraint, Regulation-Up Service plus Spinning Reserve constraint and the Operating Reserve constraint;
(b) The zonal Spinning Reserve MCP is equal to the sum of the Shadow Prices for the system-wide and zonal Regulation-Up Service plus Spinning Reserve constraint and the Operating Reserve constraint;
(c) The zonal Supplemental Reserve MCP is equal to the sum of the Shadow Price of the system-wide and zonal Operating Reserve constraint and
(d) The zonal Regulation-Down Service MCP is equal to sum of the system-wide and zonal Shadow Prices for the Regulation-Down constraint.
Page 7 of 27
(2) RTBM MCPs for Expected Regulation-Up Mileage are set equal to the highest Regulation-Up Mileage Offer of all Resource’s economically cleared to provide Regulation-Up Service in a particular Dispatch Interval. For Resource’s submitting a Regulation-Up Service Dispatch Status of “Fixed”, the cleared amount of Regulation-Up Service MW must be greater than the submitted “Fixed” MW in order to be considered economically cleared;
(3) RTBM MCPs for Expected Regulation-Down Mileage are set equal to the highest Regulation-Down Mileage Offer of all Resource’s economically cleared to provide Regulation-Down Service in a particular Dispatch Interval. For Resource’s submitting a Regulation-Down Service Dispatch Status of “Fixed”, the cleared amount of Regulation-Up Service MW must be greater than the submitted “Fixed” MW in order to be considered economically cleared;
(4) During times of Operating Reserve scarcity, MCPs will be impacted by Scarcity Prices as described under Section 4.1.5;
(5) The MCP formulations allow for the substitution of higher quality reserve products for lower quality reserve products to meet the Operating Reserve requirements to the extent that there is excess higher quality Operating Reserve available and these excess amounts provide a more economical solution. In the case of allowing Regulation-Up Service to substitute for Contingency Reserve, only the Regulation-Up Offers will be used in the evaluation. Allowing for this substitution in combination with the “price-cascading” rules described in (1) above ensures that the clearing for Operating Reserve produces Regulation-Up Service MCPs that are greater than or equal to Spinning Reserve MCPs and Spinning Reserve MCPs that are greater than or equal to Supplemental Reserve MCPs;
(a) Regulation-Down is not eligible to substitute for Spinning Reserve and Supplemental Reserve. Therefore, Resource Regulation-Down Service MCPs can be less than Spinning Reserve and/or Supplemental Reserve MCPs.
(6) The MCPs for the various Operating Reserve products as determined by the market clearing process will be sufficient to cover the Offer costs of each Resource as well as the opportunity costs incurred to allocate a portion of the Resource capacity to the supply of the corresponding Operating Reserve product in lieu of another product. The recovery of both offered cost and opportunity costs via Market Clearing Prices is inherent in the co-optimized SCED formulations, thus the separate calculation of opportunity costs is unnecessary.
(7) NDVER-DCPL curtailment load locations are always linked to a NDVER resource. The NDVER-DCPL MCP shall be the negative of the linked NDVER MCP where,
NDVER-DCPLk MCP = (NDVERk MCP ) ( -1 )
4.5.5 Settlement Location LMPs and LMP Components
For Settlement Locations that are associated with more than one PNode, the following calculations are performed to calculate the Settlement Location LMPs and the associated LMP Components. The LMPs for Settlement Locations associated with a single PNode are those LMPs directly calculated by the DA Market software as
Page 8 of 27
described under Section 4.3.1.3 and the RTBM software as described under Section 4.4.2.3.4. All nodal LMPs are subject to the price correction procedures described under Section 6.6.1. Resource Hub LMPs and the associated LMP Components will be calculated using the same methodology as Trading Hubs as described in Section 4.5.5.1.
6.1.8 Dispatchable Variable Energy Resource
All Variable Energy Resources must register as a Dispatchable Variable Energy Resource except for (i) Wind powered Variable Energy Resources with an interconnection agreement executed on or prior to May 21, 2011 and that commenced Commercial Operation before October 15, 2012 or (ii) a Qualifying Facility exercising its rights under PURPA to deliver its net output to its host utility, or (iii) Non-wind Variable Energy Resources registered on or prior to January 1, 2017 and with an interconnection agreement executed on or prior to January 1, 2017. VERs included in (i) and (iii) above may register as Dispatchable Variable Energy Resources if they are capable of being incrementally dispatched by the Transmission Provider. A Qualifying Facility exercising its rights under PURPA to deliver its net output to its host utility may register as a Dispatchable Variable Energy Resource if it is capable of being incrementally dispatched by the Transmission Provider and will be subject to the DVER market rules including Uninstructed Resource Deviation Charges. Any Resource that has previously registered as a Dispatchable Variable Energy Resource shall not subsequently register as a Non-Dispatchable Variable Energy Resources.
(1) A Dispatchable Variable Energy Resource is eligible to submit Offers for Regulation-Down if that Resource qualifies to provide Regulation-Down by passing the test described under Section 6.1.11.3.
(2) A Dispatchable Variable Energy Resource is not eligible to submit Offers for Regulation-Up, Spinning Reserve or Supplemental Reserve;
(3) Dispatchable Variable Energy Resources are committed and dispatched the same as any other Resource in the Day-Ahead Market.
(4) For the RUC and RTBM, special commitment and dispatch rules apply as defined under Section 4.2.2.5.5.
(5) Dispatchable Variable Energy Resource data submittal requirements are defined in the SPP Criteria.
6.1.9 Non-Dispatchable Variable Energy Resource
Variable Energy Resources that qualify may register as a Non-Dispatchable Variable Energy Resource. The Market Participant registering a Non-Dispatchable Variable Energy Resource must provide documentation to SPP verifying that it meets one or more of the exceptions in Section 6.1.7.1. Otherwise, the Resource must be registered as a Dispatchable Variable Energy Resource. NDVERs are committed and dispatched the same as any other Resource in the Day-Ahead Market. For the RUC and RTBM, special commitment and dispatch rules apply as defined under Section 4.2.2.5.6. Non-Dispatchable Variable Energy Resource data submittal requirements are defined in the SPP Criteria.

6.1.10 Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load (NDVER-DCPL)
Market Participants managing Non-Dispatchable Variable Energy Resource (NDVER) resources may also register as a type Demand Response Resource called a NDVER-DCPL.. The NDVER-DCPL will be registered as a type of DRR, at a separate but electrically equivalent “common bus” settlement location, connected to a NDVER resource settlement location. The NDVER-DCPL represents curtailable NDVER output for SPP economic/reliability dispatch. For the network model, the NDVER-DCPL which represents generation curtailment from an NDVER somewhat like a DRR represents curtail of load at a load settlement location.
The NDVER must first be upgraded by the owner and Market Participant (MP) in order to have the capability to accept 5-minute SPP economic/reliability dispatch instructions. The MP is required to set up and send to SPP a 5-minute NDVER Available MW capability input variable “NDVERDCPL_AMW”. Once the upgrade is completed, the MP can register a NDVER-DCPL settlement location which will indicate to SPP the NDVER is ready for SPP dispatch. The MP will then submit offer curves for both the
1) NDVER-DCPLk curtailment settlement location is linked by a Common Bus to its host
2) NDVERk
The NDVER-DCPL clearing price is formulated simply by negating the NDVER LMP or MCP price. The negating of the NDVER LMP MCP prices can at times reasonably reflect to LMP MCP price of load on constrained side of binding constraints for which the NDVER contributes to congestion.
SPP can then dispatch this type of NDVER registration by sending the resource an economic/reliability Actual dispatch instruction level through “NDVERDCPL_EMW” and will pay the MP registered NDVER-DCPL for economic/reliability curtailments based on the following calculation.
The following provides an simple example how the NDVER-DCPL A and NDVER A works together to
represent a NDVER curtailment and SPP payment when there is NDVER curtailment.
Page 10 of 27
Exhibit 6.1.10a Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load (NDVER-DCPL) Simple Example
SPP SCED will treat the NDVER- DCPLs and host NDVER resources will be treated separately, each connected by a Common Bus to the NDVER output terminals having separate settlement locations with the pseudo load having a negated price from the NDVER resource
NDVER-DCPLk curtailment loads are always linked with a host NDVERk representing the curtailment from
the actual NDVERk MW capability.
The cleared NDVER-DCPL MW quantity is calculated as follows.
NDVER-DCPLki = NDVERki MW capability – actual NDVERki MW output , where
i….dispatch interval, and
k…NDVER unit numbering
Page 11 of 27

In addition to the responsibilities described in Section 4.1.2 of this Attachment AE and under the Market
Protocols, Market Participants optionally registering a Non-Dispatachable Variable Energy Resource - Disaptch
Curtailment Pseudo Load (NDVER-DCPL) must:
(1) Identify an associated Disaptch Curtailment Pseudo Load Calculation Data Submittal Location;
(2) Identify an associated Disaptch Curtailment Pseudo Load Calculation Settlement Location;
(3) Set up for the NDVER-DCPL pseudo load electrically equivalent settlement location to NDVER
output terminals
Page 12 of 27
Exhibit 6.1.10c Simple Example for SPP Dispatch
NDVER-DCPL The NDVER must also submit 5-minute NDVER output MW capabilities. SPP will then be able to dispatch the NDVER on 5-minute intervals, resulting in SPP NDVER-DCPL 5-minute interval settlement payment when cleared by SPP for curtailment/deployment and $ 0.0 when not curtailed/deployed. Registering a NDVER-DCPL is strictly voluntary on the part of a NDVER owner who must upgrade to dispatchable controls like DVER registration requirements.
SPP SCED will treat the NDVER and associated DCPLs as mutually exclusive dispatch generation and load, each located at applicable NDVER output terminal settlement locations. The DCPL is dispatched against negation of the NDVER LMP. During periods in which SPP SCED deploys NDVER-DCPL, SPP will
1st) send a follow dispatch flag set to the NDVER and then
2nd) send an NDVER dispatch signal equal to the NDVER 5-minute curtailed output instruction (e.g. net of NDVER actual capability minus DCPL curtailed output).
SPP can curtail this type of NDVER economically in SCED through DCPL deployment without having to issue NDVER OOME instruction. SPP shall not clear any NDVER-DCPL if self-curtailed or clear amounts beyond/below the SPP dispatch instruction. The following special modeling rules apply to a DCPL Resource.
Page 13 of 27
(1) A NDVER-DCPL is a special type of Resource created to model registered curtailment settlement location linked with a host upgraded/dispatchable NDVER;
(2) A NDVER-DCPL is modeled in the Commercial Model with a separately defined Settlement Location from a NDVER that has been upgraded to be dispatchable. Thus, the NDVER-DCPL will have separate PNode or APNodes at an electrically equivalent location to the associated NDVER PNode or APNode location;
(3) A NDVER-DCPL is also included in the SPP Network Model as a load addition representing offered price of curtailment of the associate NDVER generation output;
(4) A NDVER-DCPL must have a corresponding NDVER at an electrically equivalent location;
(5) The NDVER must have telemetering installed as with DVER registration in which curtailment MW volumes can be measured by SPP settlement;
(6) The Market Participant must submit the real-time actual base NDVER output capability to SPP via SCADA on a 10-second basis
(7) The Market Participant must submit the real-time achieved curtailment of the SPP deployed NDVER-DCPL value to SPP via SCADA on a 10-second basis.
(8) SPP will issue a follow dispatch flag to all NDVERs that have deployed NDVER-DCPL curtailments. The SPP NDVER dispatch instruction will consist of the actual NDVER cleared curtailed output target during for the interval or the actual NDVER output capability during intervals in which the resource is not curtailed.
(9) For each interval, SPP will settle deployed NDVER-DCPL cleared curtailment load resulting from the SCED economic curtailment of an NDVER, if any, and will clear 0.0 MW for the NDVER-DCPL if not curtailed.
(10) The NDVER-DCPL is settled at a common bus electrically equivalent settlement locations with the NDVER LMP and MCP negated. NDVER-DCPLs can be deployed during emergency events or to avoid Regulation scarcity pricing.

Appendix G Mitigated Offer Development Guidelines … G.8 Demand Response Guidelines A Demand Response Resource is a special type of Resource created to model demand reduction associated with controllable load and/or a behind the meter Resource that is dispatchable either on a 5-minute basis or an hourly basis;
G.8.1 Demand Response Resource (DRR) Cost for Behind the Meter Generation
Market Participants using behind the meter Resource as a DDR Resource should refer to the appropriate unit type defined in this manual to develop incremental cost,
G.8.2 DRR Cost for Demand Reduction
Demand Reduction is the actual reduction of load at the direction of SPP through the commitment and dispatch of as associated DRR. This could include the cycling of air conditioners or the shutdown of an industrial production process in order to reduce the load at a site. Incremental costs can include quantifiable opportunity costs associated with the reduction, net of related offsetting increases in usage. Typically, demand reduction would be registered as a Block Demand Response Resource but an industrial site that can control its load consumption on a real-time basis could register as a Dispatchable Demand Response Resource.
G.8.3 DRR Start-Up Cost
DRR Start-Up cost is the cost to shut down or curtail a load for a given period, which does not vary with output, or the start cost of a behind the meter Resource. Start costs for DRRs represented by behind the meter Resources are defined by unit type in this manual. Start-Up costs for DRRs representing load curtailment are not specifically defined but will be evaluated on a case by case basis when submitted as part of a Market Participants fuel cost policy for reasonableness.
G.8.4 DRR Cost to Provide Spinning and/or Supplemental Reserves
Spinning Reserves from Demand Response Resources must be provided by equipment electrically synchronized to the system, and able to be fully deployed for the cleared amount within ten minutes upon request by SPP. The costs of spinning reserves from a DRR are the quantifiable incremental costs to reduce load by the offered amount within ten minutes. Incremental costs include shut down costs and opportunity costs.
G.8.5 DRR Cost to Provide Regulation
Regulation-Up and/or Regulation-Down from Dispatchable Demand Response Resources must be provided by equipment electrically synchronized to the system and able qualify for provision of
Page 15 of 27
regulation services. The costs of regulation from DDR Resources are the quantifiable incremental costs to reduce load by the offered amount within five minutes. Incremental costs include shut down costs and opportunity costs.
G.9 Non-Dispatchable Variable Energy Resource – Dispatch Curtailment Pseudo Load (NDVER-DCPL) NDVER-DCPL- NDVER curtailment load amount which is settled at the negated NDVER LMP or MCP price and is offered at a price at which the NDVER Market Participant is willing to accept economic curtailment of their NDVER.
G.9.1 NDVER-DCPL: SPP NDVER dispatch Curtailment Energy Cost Exposure
NDVER with unexpired Federal Government Production Tax Credits (PTCs) or unexpired Purchase Power Agreement (PPA) purchase contracts may include lost PTC revenue exposure or PPA buyer cost obligations associated with NDVERs within a registered NDVER-DCPL pseudo curtailment load mitigated energy or reserve offer. Lost revenues can include, but is not necessarily limited to, PTC lost revenue exposure or contractual PPA buyer cost obligations triggered by economic/reliability SPP dispatch.
NDVER Conversions to Dispatchable and Market Benefits:
The SPP MMU has made frequent claims there are significant benefits from NDVERs becoming dispatchable. Thus, for NDVERs that both register and offer NDVER-DCPL curtailments for the at least 95% of NDVER capacity, the MMU shall allow reasonable PTC revenue and contractual PPA seller/buyer cost obligations for any SPP economic/reliability dispatch.
Market Participant Release from Burden of Proof:
If the parties to NDVER PPA contract dispute the contractual terms for cost obligations when SPP economically/reliability dispatches an NDVER-DCPL, within reason, the MMU will allow such cost exposure into mitigated offers so that nether the owners/sellers/buyers placed with burden of proof for disputed contractual terms.
G.9.2 Mitigated Start-Up Offer
NDVER-DCPLs do not have start costs.
G.9.3 Mitigated No-Load Offer
NDVER-DCPLs do not have No-Load costs.
G.9.4 VOM
NDVER-DCPLs should reflect their short-run incremental VOM costs for incrementing or decrementing of NDVER output by using the most current data available. This could include the previous actual short-run incremental cost where available. For wind units, VOM dollars from the previous years should be divided by MWh generated in the same period.

4.1.2.6 Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load (NDVER-DCPL)
Page 19 of 27
Market Participants managing Non-Dispatchable Variable Energy Resource (NDVER) resources may
also register a type of Demand Response Resource (DRR) called a Dispatch Curtailment Pseudo Load –
(NDVER-DCPL) so the MP can be paid by SPP for NDVER curtailments without SPP having to issue
an OOME instruction to the NDVER. The NDVER-DCPL will be modeled on a Common Bus to the
NDVER at a separate settlement location. The NDVER-DCPL represents SPP economic/reliability
curtailment of NDVER output referred here as 5-minute dispatchable. SPP will clear the NDVER-
DCPL based on MP submitted curtailment dispatch curves and a negated NDVER LMPi. If there is no
curtailment of the NDVER the NDVER-DCPL will have 0.0 cleared MWs based on the following
formula.
NDVER-DCPLk LMPi = (NDVERk LMPi ) ( -1 )
Additionally, MCP will be cleared by SPP in the same manner.
.NDVER-DCPLk MCP = (NDVERk MCP ) ( -1 )
NDVER-DCPLk curtailment loads are always linked with a host NDVERk representing the curtailment
Registering a NDVER-DCPL is strictly a voluntary for NDVER owners and MPs. However, the
NDVER must upgraded to dispatchable controls so the NDVER can accept a 5-minute dispatch
instruction from SPP, prior to registering the NDVER-DCPL. The following provides a simple example
how the NDVER-DCPL A and NDVER A works together to represent a NDVER curtailment and SPP
payment when there is NDVER curtailment.

Mitigated Energy Offer Curves shall be submitted on a daily basis by the Market Participant in
accordance with the mitigated offer development guidelines in the Market Protocols. For Multi-
Configuration Resources (“MCR”), as defined in Attachment AE, for which a single configuration
allows physical units to be swapped (e.g., Combustion Turbine 2 for Combustion Turbine 1), the
costs used in the mitigated offer development for that configuration shall be those of the least cost
physical unit that is available and can be swapped in such configuration. The mitigated Energy
Offer Curve may be updated up to the close of the Day-Ahead Market as defined in Section 5.1 of
Attachment AE of this Tariff for use in the Day-Ahead Market. In the case a Resource is not
committed by the Day-Ahead Market, the mitigated Energy Offer Curve may be updated until the
Day-Ahead RUC begins. For Resources committed by the Day-Ahead Market, the mitigated
Energy Offer Curve submitted as of the close of the Day-Ahead Market will apply to the Day-

Ahead Market on the day before the Operating Day and the RTBM on the Operating Day; for all
other Resources the mitigated Energy Offer Curve submitted at the time the Day-Ahead RUC
begins will apply to the Day-Ahead RUC on the day before the Operating Day, and the Intra-Day
RUC processes and the RTBM on the Operating Day.
A. The Energy Offer Curve conduct thresholds are as follows:
(1) For Resources committed to address a Local Reliability Issue, the conduct threshold
is a 10% increase above the mitigated Energy Offer Curve;

3.2(A)(1), the conduct threshold is a 17.5% increase above the mitigated Energy
Offer Curve;
(3) For all other Resources the conduct threshold is a 25% increase above the mitigated
Energy Offer Curve.
B. The Transmission Provider shall apply mitigation measures by replacing the Energy Offer
Curve with the mitigated Energy Offer Curve if:
(1) The Resource’s Energy Offer Curve exceeds the mitigated Energy Offer Curve by
the applicable conduct threshold; and
(2) The Resource has local market power as determined in Section 3.1; and
(3) The Resource either:
(a) Fails the Market Impact Test as described in Section 3.7, or
(b) Is manually committed by the Transmission Provider or by a local
transmission operator.
An Energy Offer below $25/MWh will not be subject to mitigation measures for economic
withholding.
C. The mitigated energy offer shall be the Resource’s short-run marginal cost of producing
energy as determined by the unit’s heat rate; fuel costs and the costs related to fuel usage,
such as transportation and emissions costs (“total fuel related costs”); and Energy Offer
Curve (“EOC”) variable operations and maintenance costs (“VOM”) as detailed in the
Market Protocols.
D. Opportunity cost shall be an estimate of the Energy and Operating Reserve Markets
revenues net of short run marginal costs for the marginal forgone run time during the
timeframe when the Resource experiences the run-time restrictions as detailed in the
Market Protocols. The run-time restrictions shall be updated as specified in the Market
Protocols, with more frequent updating to occur the fewer hours that remain available,
Page 25 of 27
consistent with the Market Protocols. The Market Participant may include in the
calculation of its mitigated Energy Offer Curve an amount reflecting the resource-specific
opportunity costs expected to be incurred under the following circumstances:
(1) Externally imposed environmental run-hour restrictions; or
(2) Physical equipment limitations on the number of starts or run-hours, as verified by
the Market Monitoring Unit and determined by reference to the manufacturer’s
recommendation or bulletin, or a documented restriction imposed by the applicable
insurance carrier; or
(3) Fuel Supply Limitations.
Resource specific opportunity costs are calculated by forecasting Locational Marginal
Prices based on futures contract prices for natural gas and the historical relationship
between the SPP system marginal Energy component of LMP and the price of natural gas,
as determined by the SPP Market Monitoring Unit. The formulas and instructions in the
price forecast model shall be determined by the SPP Market Monitoring Unit and published
in the Market Protocols as part of the Mitigated Offer Development Guidelines, updated,
as needed, by the SPP Market Monitoring Unit. Such forecasts of LMPs shall take into
account historical variability, and basis differentials affecting the Settlement Location at
which the Resource is located for the three-year period immediately preceding the period
of time in which the Resource is bound by the referenced restrictions, and shall subtract
therefrom the forecasted costs to generate energy at the Settlement Location at which the
Resource is located, as specified in more detail in Appendix G of the Market Protocols. If
the difference between the forecasted Locational Marginal Prices and forecasted costs to
generate energy is negative, the resulting opportunity cost shall be zero. The Market
Monitoring Unit will verify all Market Participants’ opportunity cost calculations for
consistency and accuracy. When the Market Monitoring Unit determines that the market
price for any period was not competitive, it will adjust the LMP forecasting process used
in the opportunity cost calculations to ensure that forecasted LMPs do not reflect non-
competitive market conditions.
The following formula shall apply to all mitigated Energy Offer Curves:
Mitigated Energy Offer ($/MWh) = HeatRate (mmBtu/MWh) *
Performance Factor * Total Fuel Related Costs ($/mmBtu) + EOC VOM ($/MWh) + Opportunity
Costs ($/MWh)
Page 26 of 27
The Market Participant shall submit heat rate curves, descriptions of how spot fuel prices and/or
contract prices are used to calculate fuel costs, variable fuel transportation and handling
costs, emissions costs, and VOM to the Market Monitoring Unit. All cost data and cost
calculation descriptions are subject to the review and approval of the SPP Market
Monitoring Unit to ensure reasonableness and consistency across Market Participants. The
information will be sufficient for replication of the mitigated Energy Offer Curve and shall
include, among other data, the following information:
(1) For fuel costs, Market Participants shall provide the Market Monitoring Unit with
an explanation of the Market Participants’ fuel cost policy, indicating whether fuel
purchases are subject to a fixed contract price and/or spot pricing and specifying
the contract price and/or referenced spot market prices. Any included fuel
transportation and handling costs must be short-run marginal costs only, exclusive
of fixed costs.
(2) For emissions costs, Market Participants shall report the emissions rate of each of
their units and indicate the applicable emissions allowance cost.
(3) For VOM costs, Market Participants shall submit VOM costs, calculated in
adherence with the Appendix G of the Market Protocols, reflecting short-run
marginal costs, exclusive of fixed costs.
Further details associated with the development, validation, and updating of these costs are
included in Appendix G of the Market Protocols.
For Demand Response Resources utilizing Behind-The-Meter Generation, the mitigated
Energy Offer Curve shall be developed in the same manner as any other generating
Resource as described above. For Demand Response Resources utilizing load reduction,
the mitigated Energy Offer Curve shall reflect the quantifiable opportunity costs associated
with the reduction, net of related offsetting increases in usage.
For Dispatchable Variable Energy Resources, the mitigated Energy Offer Curve may
include, but shall not exceed, any quantifiable costs that vary by MWh output, including
short-run incremental VOM. Mitigation will not apply to Non-Dispatchable Variable
Energy Resources in the Real-Time Balancing Market; monitoring of Energy Offers for
Non-Dispatchable Variable Energy Resources will occur.
E. Intra-day changes to the mitigated Energy Offer Curve are allowed under the following
conditions:
Page 27 of 27
1) In the event that the Transmission Provider requests that a Resource remain online
past their commitment period by the Day-Ahead Market or a RUC process, the
Market Participant may submit an updated mitigated energy offer curve that reflects
the procurement of higher cost fuel;
2) A Resource must switch fuels due to unforeseen operating conditions; or
3) A Market Participant employing the Quick-Start Resource logic as described in the
Market Protocols may update its mitigated Energy Offer Curve after the Day-Ahead
RUC clears on the day before the Operating Day, as described in Appendix G of
the Market Protocols.
Intra-day changes to the mitigated energy offer curve must follow the mitigated offer
development guidelines in Appendix G of the Market Protocols. Any such changes will be
validated by the Market Monitor.
F. In all cases under this Section 3.2, cost data submitted for the development of mitigated
offers, including opportunity cost data, shall be subject to the confidentiality provisions set
forth in Section 11 of Attachment AE of this Tariff.

RR #: 263 Date: 2/3/2018
RR Title: NDVER to DVER Conversion through Incentives
SUBMITTER INFORMATION Name: Grant Wilkerson Cliff Franklin Company: Westar Energy, Inc.
Email: [email protected] [email protected]
Phone: 785.231.9331 443.226.7787
COMMENTS Westar Energy took comments from MWG members and SPP staff at the January MWG meeting. Questions were directed primarily on three questions. First, how will NDVER MPs/owners, which voluntarily re-register the unit to become dispatchable (via registration of a Dispatch Curtailment Pseudo Load “NDVER-DCPL”), be paid and how will such costs be allocated onto SPP members? Second, who would be responsible for upgrades necessary to make NDVER dispatchable if the NDVER Owner is not a Market Participant? Third, doesn’t providing incentives to NDVERs and not DVERs favorably treat similarly situated MPs inequitably? Fourth, proponents of the SPP “stick” approach forcing NDVERs to convert to DVERs asks why is this incentive necessary if such wind farms can roll in PTC & rate exposure in formulating negative resource offers (e.g. -65 $/mwh offers)? First Question: How will RR263 curtailment payment obligations be allocated?
The answer is allocation through the Real-Time RNU distribution. Westar has added language to the pre-existing RR263 to uplift SPP NDVER-DCPL payment obligations onto the RNU Distribution. Additionally, additions were made to correctly calculate the payment to NDVER-DCPL facilities for Day-Ahead and Real-Time Asset energy. Changes are highlighted to the original RR263 in yellow. Many on MWG and SPP assert the great market benefits that would result from forcing NDVER conversion to dispatchable DVERs. This constitutes an incentive for NDVERs to convert to DVER by making them whole for applicable contract payments. Like GFA carve-out transactions, Westar believes NDVERs are grandfathered from dispatchable status, which was the tariff & protocol that NDVER Purchase Power Agreements (PPAs) were based and structured around.
Second Question: Who would be responsible for upgrades necessary to make NDVER dispatchable if the NDVER Owner is not a Market Participant?
Since RR263 is voluntary for NDVER owners/buyers to become dispatchable, it leaves it to NDVER owners/buyers/MP to coordinate upgrades and contract renegotiation to make the resource dispatchable apart from SPP influence. However, RR272 which forces NDVER to DVER conversion should be changed to make the actual generator interconnection owner responsible for NDVER conversion since the AO is the only one having control over facility upgrades and operation.
Third Question: Doesn’t providing incentives to NDVERs and not DVERs favorably treat similarly situated MPs inequitably?
The premise that owners/MPs of NDVERs and DVERs wind facilities are similarly situated is simply not true. NDVER and DVER owners/MPs are no more similar than owners/MPs of GFA carve-out supply and other MPs. The primary difference is that DVER owners/buyers had SPP notice that their resource would be dispatchable, thus resource supply contracts were negotiated with that expectations. Conversely, the owners/buyers of older NDVER resources were provided notice they would not be dispatchable if the resource was constructed prior to October 15, 2012, thus construction/technology/contracts were negotiation on the resource only be curtailed by emergency OOMEs.
Fourth Question: Why is this incentive necessary if NEVER MPs can roll in PTC & rate exposure in formulating negative resource offers (e.g. -65 $/mwh offers)?
There are three answers to this question. First, forcing NDVER owners to attempt to be made-whole to NDVER PPA contract terms through market offers is risky, at best, and does not constitute an incentive for NDVERs to absorb potential repowering expenses and cost exposure (such as MMU allowable cost components) within wind offers screening which may, or may not, allow PTC and rates when evaluating when evaluating NDVER uneconomic production. Second, most NDVER owners have firm or firm w/ redispatch service approved by SPP years before many DVER interconnections, many w/o firm service or contribution to transmission deliverability. If NDVERs convert to DVER status have a greater impact on binding constraints than neighboring DVERs, the NDVER w/ firm service could be economically dispatched to 0 MW before the neighboring DVERs (having lesser impact factors and possibly having no transmission service or contribution to transmission deliverability) are allowed by SCED at full wind output. This doesn’t seem fair or equitable. Third, dispatch of wind resources can restore local area LMPs favoring other resources having less impact constraints. When the LMP price is restored and curtailment of DVERs can be deployed by SCED back to their full output capability the DVER ramp constrained to 20% of the unit rating. This is an advantage for wind resources not curtailed. If older wind resources struggle to follow dispatch instruction, the 20% ramp restriction and URD could become an issue for older NDVER resource owners having technologies not built for 5-minute economic dispatch.
PROPOSED REVISION
Market Protocols
1. Glossary
….
Demand Response Load
A measurable load that is capable of being reduced at the instruction of the SPP operator and subsequently increased at the instruction of the SPP operator that is identified in the registration of a Dispatchable Demand Response Resource or a Block Demand Response Resource.
….
Dispatchable Variable Energy Resource
A Variable Energy Resource that is capable of being incrementally dispatched by the Transmission Provider.
….
Non-Dispatchable Variable Energy Resource
A Variable Energy Resource that is not capable of being incrementally dispatched down by the Transmission Provider.
Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load – (NDVER-DCPL)
After a Market Participant (MP) has upgraded a Non-Dipatchable Variable Energy Resource (NDVER) to accept 5-minute economic/reliability dispatch instructions from SPP, the MP may register a Dispatch Curtailment Pseudo Load NDVER-DCPL so the MP can be paid by SPP for NDVER curtailments without SPP having to issue an OOME instruction. The NDVER-DCPL will represent a MP capacity/price offer for SPP to using in clearing curtailment NDVER MWs.. During emergencies or reliability issues which SCED can’t solve, SPP shall continue to issue OOME instructions to NDVERs.
SPP shall clear NDVER-DCPL curtailment MWs for the NDVER using the negated NDVER LMPi.. SPP shall settle the NDVER-DCPL based NDVER curtailed MWs at a negated NDVER LMPi or negated NDVER MCP price based upon the NDVER-DCPL offer curves. Self or curtailment more than SPP dispatch instructions will not be cleared by SPP.
-….
4.5.3.4 GFA Carve Out or FSE Uplift
GFA Carve Out or FSE Schedules result in removal of the energy, congestion, and marginal losses for the transaction from settlement statements. SPP will capture the congestion charges and marginal loss charges related to the GFA Carve Outs or FSEs. These charges will be offset by the ARR/TCR settlement that would have been claimed for the GFA Carve Out or FSE under the normal ARR/TCR process and the distribution of the Marginal Loss Overcollection funds. Candidate ARRs associated with the GFA Carve Out or FSE service shall not be nominated for a product period if, based upon the twelve preceding months for which congestion data is available, such ARR, had it been converted to a TCR, would have resulted in a TcrFundHrlyAmt net charge to the holder of the TCR over that product period, as defined for the annual ARR allocation process. However, until twelve months of Integrated Marketplace data is available, SPP will use relevant data from both the EIS Market and the Integrated Marketplace to estimate whether the result is a net charge.
(i) For the MW capacity associated with each FSE, the sink for the ARR/TCR shall be the (1) load Settlement Location within the UMZ, (2) interface with an external Balancing Authority, or (3) FSE Transfer Point, as appropriate. For ARR/TCR activity from FSE Transfer Points to load external to the UMZ but internal to the Transmission Provider, the normal ARR/TCR process is available to the applicable Market Participants from the FSE Transfer Point to the load consistent with the transmission service reservation.
4.5.4 Calculation of LMPs, LMP Components and MCPs
SPP uses a co-optimized SCED model to compute Locational Marginal Prices (LMPs) for Energy at PNodes. The LMPs are then mapped to Settlement Locations in the commercial model. The SCED model also computes Market Clearing Prices (MCPs) for Regulation-Up Service, Regulation-Up Mileage, Regulation-Down Service, Regulation-Down Mileage, Spinning Reserve and Supplemental Reserve on a Reserve Zone basis. For the DA Market, LMPs and MCPs are calculated on an hourly basis. For the RTBM, LMPs and MCPs are calculated for each 5-minute Dispatch Interval. Inputs to SCED for the DA Market
are as described under Section 4.3.1.1 and inputs to SCED for the RTBM are as described under Section 4.4.2.2. The following subsections further describe how LMPs, LMP Components and MCPs are calculated.
4.5.4.1 LMP Calculations and LMP Components
The LMP at a PNode is the cost of delivering an incremental MW of energy at that specific PNode, while satisfying all operational constraints where such cost will include applicable Demand Curve prices if the incremental MW of energy causes a corresponding increase in shortage conditions where such Demand Curve prices and shortage conditions are as described under Section 4.1.5. The LMP at any PNode is the sum of three components; the marginal costs of Energy (Marginal Energy Component or MEC), the marginal cost of losses (Marginal Loss Component or MLC), and the marginal cost of congestion (Marginal Congestion Component or MCC).
LMP Components at PNode i are calculated based upon the following formulas:
LMPi = MEC + MLCi + MCCi
Where:
(1) MEC is the component of LMPi representing the marginal cost of Energy;
(2) MLCi is the component of LMPi representing the marginal cost of losses at PNode i relative to the Reference Bus;
(3) MCCi is the component of LMPi representing the marginal cost of congestion at ENode i relative to the Reference Bus; and
(4) The Reference Bus represents the network Distributed Load Bus.
(5) NDVER-DCPL curtailment load locations are always linked to a NDVER resource. The NDVER-DCPL LMP shall be the negative of the linked NDVER LMP where,
NDVER-DCPLk LMPi = (NDVERk LMPi ) ( -1 )
4.5.4.1.1 Marginal Losses Component Calculation
The MLCi at each PNode i is defined by the following equations:
MLCi = -MLSFi * MEC
MLSFi = ∂ (SPP Losses) / ∂ Pi
Where:
(1) SPP Losses = SPP transmission system losses;
(2) MLSFi = Marginal Loss Sensitivity Factor at PNode i;
(3) MEC is the component of LMPi representing the marginal cost of Energy;
(4) Pi = Net injection at PNode i.
(4)(5) NDVER-DCPL pseudo load will not be considered within MLCi since it represents a curtailment of NDVER generation and does not represent actual physical load.
The MLSFi is a linearized estimate of the change in SPP transmission losses that will result from a 1 MW injection at PNode i coupled with a corresponding withdrawal at the Reference Bus to maintain global power balance (the withdrawal at the Reference Bus will generally be higher or lower than 1 MW since there will be a change in losses). Marginal loss sensitivity factors are dependent on topology, node injections and node withdrawals, and are only considered constant within a small deviation from a fixed operating point.
4.5.4.1.2 Marginal Congestion Component Calculation
The MCC at each PNode i is defined by the following equations
MCCi = - ( ∑=
K
k 1Sensik * SPk )
Sensik = ∂ Flowk / ∂ Pi
Where:
(1) K is the number of transmission constraints;
(2) Sensik is the linearized estimate of the change in the constraint k flow resulting from an incremental energy injection at PNode i coupled with an incremental energy withdrawal at the Reference Bus;
(3) Flowk = Calculated flow for constraint k;
(4) SPk = is the Shadow Price of constraint k;
(5) Pi = Net injection at PNode i.
4.5.4.1.3 Marginal Energy Component Calculation
The MEC is defined as the computed LMP at the Reference Bus. By definition, MCC and MLC components are zero at the Reference Bus.
4.5.4.2 MCP Calculations
The MCP represents the cost of supplying an increment of operating reserve, taking into account lost opportunity cost and is composed of the marginal Operating Reserve costs and marginal costs associated with Operating Reserve scarcity. The DA Market and RTBM MCPs for Regulation-Up Service, Spinning Reserve and Supplemental Reserve at a Reserve Zone for Resources with cleared Regulation-Up Service, Spinning Reserve and/or Supplemental Reserve at that Reserve Zone are equal to the summation of the applicable Shadow Prices associated with each Operating Reserve constraint. This type of MCP formulation is referred to as “price-cascading”. MCPs applied to Excess Regulation-Up Mileage, Unused Regulation-Up Mileage. Excess Regulation-Down Mileage and Unused Regulation-Down Mileage are calculated for the RTBM only as described in (2) and (3) below.
(1) There are four sets of constraints: (i) an Operating Reserve constraint which is set equal to the sum of the Contingency Reserve requirement and the Regulation-Up requirement; (ii) a Regulation-Up Service plus Spinning Reserve constraint which is set equal to the sum of the Regulation-Up requirement and the Spinning Reserve requirement; and (iii) a Regulation-Up Service constraint which is set equal to the Regulation-Up requirement; and (iv) a Regulation-Down Service constraint which is set equal to the Regulation-Down requirement. These constraints apply on both a system-wide basis and a Reserve Zone basis. MCPs for each Reserve Zone are calculated as follows:
(a) The zonal Regulation-Up Service MCP is equal to sum of the system-wide and zonal Shadow Prices for the Regulation-Up constraint, Regulation-Up Service plus Spinning Reserve constraint and the Operating Reserve constraint;
(b) The zonal Spinning Reserve MCP is equal to the sum of the Shadow Prices for the system-wide and zonal Regulation-Up Service plus Spinning Reserve constraint and the Operating Reserve constraint;
(c) The zonal Supplemental Reserve MCP is equal to the sum of the Shadow Price of the system-wide and zonal Operating Reserve constraint and
(d) The zonal Regulation-Down Service MCP is equal to sum of the system-wide and zonal Shadow Prices for the Regulation-Down constraint.
(2) RTBM MCPs for Expected Regulation-Up Mileage are set equal to the highest Regulation-Up Mileage Offer of all Resource’s economically cleared to provide Regulation-Up Service in a particular Dispatch Interval. For Resource’s submitting a Regulation-Up Service Dispatch Status of “Fixed”, the cleared amount of Regulation-Up Service MW must be greater than the submitted “Fixed” MW in order to be considered economically cleared;
(3) RTBM MCPs for Expected Regulation-Down Mileage are set equal to the highest Regulation-Down Mileage Offer of all Resource’s economically cleared to provide Regulation-Down Service in a particular Dispatch Interval. For Resource’s submitting a Regulation-Down Service Dispatch Status of “Fixed”, the cleared amount of Regulation-Up Service MW must be greater than the submitted “Fixed” MW in order to be considered economically cleared;
(4) During times of Operating Reserve scarcity, MCPs will be impacted by Scarcity Prices as described under Section 4.1.5;
(5) The MCP formulations allow for the substitution of higher quality reserve products for lower quality reserve products to meet the Operating Reserve requirements to the extent that there is excess higher quality Operating Reserve available and these excess amounts provide a more economical solution. In the case of allowing Regulation-Up Service to substitute for Contingency Reserve, only the Regulation-Up Offers will be used in the evaluation. Allowing for this substitution in combination with the “price-cascading” rules described in (1) above ensures that the clearing for Operating Reserve produces Regulation-Up Service MCPs that are greater than or equal to Spinning Reserve MCPs and Spinning Reserve MCPs that are greater than or equal to Supplemental Reserve MCPs;
(a) Regulation-Down is not eligible to substitute for Spinning Reserve and Supplemental Reserve. Therefore, Resource Regulation-Down Service MCPs can be less than Spinning Reserve and/or Supplemental Reserve MCPs.
(6) The MCPs for the various Operating Reserve products as determined by the market clearing process will be sufficient to cover the Offer costs of each Resource as well as the opportunity costs incurred to allocate a portion of the Resource capacity to the supply of the corresponding Operating Reserve product in lieu of another product. The recovery of both offered cost and opportunity costs via Market Clearing Prices is inherent in the co-optimized SCED formulations, thus the separate calculation of opportunity costs is unnecessary.
(7) NDVER-DCPL curtailment load locations are always linked to a NDVER resource. The NDVER-DCPL MCP shall be the negative of the linked NDVER MCP where,
NDVER-DCPLk MCP = (NDVERk MCP ) ( -1 )
4.5.5 Settlement Location LMPs and LMP Components
For Settlement Locations that are associated with more than one PNode, the following calculations are performed to calculate the Settlement Location LMPs and the associated LMP Components. The LMPs for Settlement Locations associated with a single PNode are those LMPs directly calculated by the DA Market software as described under Section 4.3.1.3 and the RTBM software as described under Section 4.4.2.3.4. All nodal LMPs are subject to the price correction procedures described under Section 6.6.1. Resource Hub LMPs and the associated LMP Components will be calculated using the same methodology as Trading Hubs as described in Section 4.5.5.1.
4.5.8.1 Day-Ahead Asset Energy Amount
(1) A DA Market credit or charge for net physical Energy activity associated with load and Resources, adjusted for Bilateral Settlement Schedules for Energy, is calculated at each Settlement Location for each Asset Owner for each Hour. The net amount is calculated as follows:
#DaEnergyHrlyAmt a, s, h = DaLmpHrlyPrc s, h * ( DaClrdHrlyQty a, s, h
- ∑t
DaEnFinHrlyQty a, s, h, t )
IF DaDevCapbltyHrlyQty a, s, h > DaClrdHrlyQty a, s, h
THEN
#DaEnergyHrlyAmt a, s, h = DaLmpHrlyPrc s, h * (-1) * ( DaDevCapbltyHrlyQty a, s, h - DaClrdHrlyQty a, s, h)
+ DaLmpHrlyPrc s, h * DaClrdHrlyQty a, s, h - ∑t
DaEnFinHrlyQty a, s, h, t )
(2) For each Asset Owner, a daily amount is calculated at each Settlement Location. The net daily amount is calculated as
follows:
DaEnergyDlyAmt a, s, d = ∑h
DaEnergyHrlyAmt a, s, h
(3) For each Asset Owner associated with Market Participant m, a daily amount is calculated. The net daily amount is calculated as follows:
DaEnergyAoAmt a, m, d = ∑s
DaEnergyDlyAmt a, s, d
(4) For each Market Participant, a daily amount is calculated representing the sum of Asset Owner amounts associated with that Market Participant. The net amount is calculated as follows:
DaEnergyMpAmt m, d = ∑a
DaEnergyAoAmt a, m, d
Field Code Changed
(5) For FERC Electric Quarterly Reporting (“EQR”) purposes, SPP calculates hourly sales volume and prices associated with this Charge Type for each Asset Owner as follows:
(a) #EqrDaAssetEnergyHrlyQty a, s, h
= (-1) * Min(0, DaClrdHrlyQty a, s, h - ∑t
DaEnFinHrlyQty a, s, h, t )
(b) IF #EqrDaAssetEnergyHrlyQty a, s, h > 0 THEN #EqrDaAssetEnergyHrlyPrc a, s, h = DaLmpHrlyPrc s, h

4.5.9.1 Real-Time Asset Energy Amount
(1) The Real-Time Asset Energy Amount can be either a credit to an Asset Owner or a charge to an Asset Owner and is calculated on a net basis at each Settlement Location for:
(a) The difference between actual metered supply MWh amounts in a Dispatch Interval and cleared Resource Offers in the DA Market;
(b) The difference between actual metered demand MWh amounts in a Dispatch Interval and all cleared Demand Bids in the DA Market; and
(c) Real-Time Bilateral Settlement Schedules for Energy in a Dispatch Interval.
The net amount to each Asset Owner (AO) for each Settlement Location in a Dispatch Interval is calculated as follows:
#RtEnergy5minAmt a, s, i = RtLmp5minPrc s, i
* [ (RtBillMtr5minQty a, s, i - DaClrdHrlyQty a, s, h )

Where,
(a) The 5-minute billable meter determinant at the Settlement Location level is the sum of the 5-minute billable meter determinants at the Meter Data Submittal Location level as shown in the formula below. Most Settlement Locations will be comprised of only one Meter Data Submittal Location, but in certain cases a single Settlement Location will represent multiple Meter Data Submittal Locations, each of which is in a separate Settlement Area. Since the calibration function must be performed within Settlement Area boundaries, it is done before summing the data to the Settlement Location level. The 5-minute determinants are expressed in terms of levelized MW at both the Settlement Location and Meter Data Submittal Location level.
RtBillMtr5minQty a, s, i = ∑ml

(b) The 5-minute billable meter determinant at the Meter Data Submittal Location level is the sum of the 5-minute adjusted meter determinant and the 5-minute calibration meter determinants at the Meter Data Submittal Location level as shown in the formula below. Both 5-minute determinants are expressed in terms of levelized MW.

approach, it is assumed that meter submissions, with the exception of those with a “top-down load” relationship to the Settlement Area – generally those for which a top-down calculation is used – are net of transmission losses. Losses will be backed out of load submittals for the “top-down load”. For Demand Response Resources, the hierarchy is the same for submitted data, but instead of defaulting to the State Estimator data, the Resource output is calculated as the maximum of zero or the difference between (i) and (ii) below. If the baseline hourly load profile of the DRL was not submitted, the State Estimator snapshot will be used for this value in (i) below. (i) The minimum of (1) the hourly baseline load profile of the DRL submitted for the Demand Response Load,
or (2) the State Estimator snapshot for the Demand Response Load for the 5 minute interval immediately preceding the first dispatch interval (i = -1) in which the Demand Response Resource is dispatched (for a BDR, this is the dispatch interval immediately preceding the hour in which the BDR was committed. For a DDR, it is the dispatch interval immediately preceding the first dispatch interval in which the DDR receives a dispatch instruction greater than zero.) and
(ii) The Adjusted Meter Quantity for the DRL for each 5 minute interval. Registration records whether meter submittals are permitted or if the Demand Response Resource must rely solely on the calculated Resource output. For loads in which a Demand Response Resource is imbedded within a Settlement Location, the response is added to the load meter data “grossing-up” the MW to avoid introducing deviation between DA Market cleared Energy and the billable meter quantity. 5-minute adjusted meter, state estimator, SCADA and gross-up determinants are expressed in terms of levelized MW and both hourly and 5-minute submitted actual determinants are in terms of MWh. The formula for the 5-minute adjusted meter determinant is shown below.

(e) The 5-minute calibration meter determinant is the hourly quantity, profiled by State Estimator data into 5-minute intervals as shown in the formula below.

(f) The hourly calibration meter determinant is the weighted distribution of Settlement Area residual among load in the Settlement Area (excluding Resources and load pseudo-tied into SPP, but not accounted for in the submittal of interchange of any Settlement Area). The hourly calibration meter determinant is expressed in terms of levelized MW. The Statutory Load Obligations in Western-UGP will be exempted fro calibration.

(g) The hourly adjusted meter determinant is the sum of the 5-minute adjusted meter determinant divided by 12. The hourly adjusted meter determinant is expressed in terms of levelized MW. The formula for the hourly adjusted meter determinant is shown below.
#RtAdjMtrHrlyQty a, ml, h = ∑i
RtAdjMtr5minQty a, ml, i / 12
(h) The hourly residual load determinant is the net difference between generation & load (excluding Resources and load pseudo-tied into SPP, but not accounted for in the submittal of interchange of any Settlement Area), interchange and losses per Settlement Area. Hourly Net Actual Interchange is derived as the sum of the hourly metering submitted for aggregate ties between interconnected Settlement Areas. Missing tie values are replaced with State Estimator values. The hourly residual determinant is expressed in terms of levelized MW. The formula for the hourly residual load determinant is shown below.

4.5.12 Revenue Neutrality Uplift Distribution Amount
(1) A charge or credit will be calculated at each Settlement Location for each Asset Owner for each hour in order for SPP to remain revenue neutral. Contributors to revenue non-neutrality include:
(a) Rounding errors (related to the calculation of all Charges/Credits);
(b) Inadvertent Interchange (as calculated as shown in equation b.3 below);
(c) Joint Operating Agreement Charges/Credits;
(d) RTBM congestion (as calculated as shown in equation b.4 below);
(e) RTBM Regulation Deployment Adjustment;
(f) Make-Whole payments for Out-of-Merit Energy; and
(g) Miscellaneous Charges/Credits
(g)(h) SPP Payment obligations for cleared Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load – “NDVER-DCPL” (as calculated as shown in equation b.5 below).
The amount will be determined by multiplying the Asset Owner hourly determinant by a daily Revenue Neutrality Uplift (RNU) rate. The Asset Owner hourly determinant is equal to the sum that Asset Owner’s actual generation MWh, actual load MWh, actual Interchange Transaction MWh, DA Market cleared Virtual Offer MWh and DA Market cleared Virtual Bid MWh for the Hour, where all of these values are assumed to be positive values.
The calculation of the Revenue Neutrality Uplift (RNU) for each Asset Owner and Settlement Location in the SPP footprint can result in residual amounts due to rounding. The sum of the residual amounts due to rounding can result in SPP not being revenue neutral for the Operating Day. The residual amounts for each Operating Day will be summed on a yearly basis. The annual residual amount, whether a credit or a charge, will be uplifted to the Asset Owners and Settlement Locations. On Operating Day March 1 of every year, SPP will uplift the annual residual amount with a Miscellaneous Adjustment to the Asset Owners and Settlement Locations.
The amount to each applicable Asset Owner is calculated as follows.

6.1.8 Dispatchable Variable Energy Resource
All Variable Energy Resources must register as a Dispatchable Variable Energy Resource except for (i) Wind powered Variable Energy Resources with an interconnection agreement executed on or prior to May 21, 2011 and that commenced Commercial Operation before October 15, 2012 or (ii) a Qualifying Facility exercising its rights under PURPA to deliver its net output to its host utility, or (iii) Non-wind Variable Energy Resources registered on or prior to January 1, 2017 and with an interconnection agreement executed on or prior to January 1, 2017. VERs included in (i) and (iii) above may register as Dispatchable Variable Energy Resources if they are capable of being incrementally dispatched by the Transmission Provider. A Qualifying Facility exercising its rights under PURPA to deliver its net output to its host utility may register as a Dispatchable Variable Energy Resource if it is capable of being incrementally dispatched by the Transmission Provider and will be subject to the DVER market rules including Uninstructed Resource Deviation Charges. Any Resource that has previously registered as a Dispatchable Variable Energy Resource shall not subsequently register as a Non-Dispatchable Variable Energy Resources.
(1) A Dispatchable Variable Energy Resource is eligible to submit Offers for Regulation-Down if that Resource qualifies to provide Regulation-Down by passing the test described under Section 6.1.11.3.
(2) A Dispatchable Variable Energy Resource is not eligible to submit Offers for Regulation-Up, Spinning Reserve or Supplemental Reserve;
(3) Dispatchable Variable Energy Resources are committed and dispatched the same as any other Resource in the Day-Ahead Market.
(4) For the RUC and RTBM, special commitment and dispatch rules apply as defined under Section 4.2.2.5.5.
Page 39 of 59
(5) Dispatchable Variable Energy Resource data submittal requirements are defined in the SPP Criteria.
6.1.9 Non-Dispatchable Variable Energy Resource
Variable Energy Resources that qualify may register as a Non-Dispatchable Variable Energy Resource. The Market Participant registering a Non-Dispatchable Variable Energy Resource must provide documentation to SPP verifying that it meets one or more of the exceptions in Section 6.1.7.1. Otherwise, the Resource must be registered as a Dispatchable Variable Energy Resource. NDVERs are committed and dispatched the same as any other Resource in the Day-Ahead Market. For the RUC and RTBM, special commitment and dispatch rules apply as defined under Section 4.2.2.5.6. Non-Dispatchable Variable Energy Resource data submittal requirements are defined in the SPP Criteria.
6.1.10 Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load (NDVER-DCPL)
Market Participants managing Non-Dispatchable Variable Energy Resource (NDVER) resources may also register as a type Demand Response Resource called a NDVER-DCPL.. The NDVER-DCPL will be registered as a type of DRR, at a separate but electrically equivalent “common bus” settlement location, connected to a NDVER resource settlement location. The NDVER-DCPL represents curtailable NDVER output for SPP economic/reliability dispatch. For the network model, the NDVER-DCPL which represents generation curtailment from an NDVER somewhat like a DRR represents curtail of load at a load settlement location.
The NDVER must first be upgraded by the owner and Market Participant (MP) in order to have the capability to accept 5-minute SPP economic/reliability dispatch instructions. The MP is required to set up and send to SPP a 5-minute NDVER Available MW capability input variable “NDVERDCPL_AMW”. Once the upgrade is completed, the MP can register a NDVER-DCPL settlement location which will indicate to SPP the NDVER is ready for SPP dispatch. The MP will then submit offer curves for both the
1) NDVER-DCPLk curtailment settlement location is linked by a Common Bus to its host
2) NDVERk
The NDVER-DCPL clearing price is formulated simply by negating the NDVER LMP or MCP price. The negating of the NDVER LMP MCP prices can at times reasonably reflect to LMP MCP price of load on constrained side of binding constraints for which the NDVER contributes to congestion.
SPP can then dispatch this type of NDVER registration by sending the resource an economic/reliability Actual dispatch instruction level through “NDVERDCPL_EMW” and will pay the MP registered NDVER-DCPL for economic/reliability curtailments based on the following calculation.
The following provides an simple example how the NDVER-DCPL A and NDVER A works together to
represent a NDVER curtailment and SPP payment when there is NDVER curtailment.
Page 40 of 59
Exhibit 6.1.10a Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load (NDVER-DCPL) Simple Example
SPP SCED will treat the NDVER- DCPLs and host NDVER resources will be treated separately, each connected by a Common Bus to the NDVER output terminals having separate settlement locations with the pseudo load having a negated price from the NDVER resource
NDVER-DCPLk curtailment loads are always linked with a host NDVERk representing the curtailment from
the actual NDVERk MW capability.
The cleared NDVER-DCPL MW quantity is calculated as follows.
NDVER-DCPLki = NDVERki MW capability – actual NDVERki MW output , where
i….dispatch interval, and
k…NDVER unit numbering

Exhibit 6.1.10b Simple Example layout
In addition to the responsibilities described in Section 4.1.2 of this Attachment AE and under the Market
Protocols, Market Participants optionally registering a Non-Dispatachable Variable Energy Resource - Disaptch
Curtailment Pseudo Load (NDVER-DCPL) must:
(1) Identify an associated Disaptch Curtailment Pseudo Load Calculation Data Submittal Location;
(2) Identify an associated Disaptch Curtailment Pseudo Load Calculation Settlement Location;
(3) Set up for the NDVER-DCPL pseudo load electrically equivalent settlement location to NDVER
output terminals
Page 42 of 59
Exhibit 6.1.10c Simple Example for SPP Dispatch
NDVER-DCPL The NDVER must also submit 5-minute NDVER output MW capabilities. SPP will then be able to dispatch the NDVER on 5-minute intervals, resulting in SPP NDVER-DCPL 5-minute interval settlement payment when cleared by SPP for curtailment/deployment and $ 0.0 when not curtailed/deployed. Registering a NDVER-DCPL is strictly voluntary on the part of a NDVER owner who must upgrade to dispatchable controls like DVER registration requirements.
SPP SCED will treat the NDVER and associated DCPLs as mutually exclusive dispatch generation and load, each located at applicable NDVER output terminal settlement locations. The DCPL is dispatched against negation of the NDVER LMP. During periods in which SPP SCED deploys NDVER-DCPL, SPP will
1st) send a follow dispatch flag set to the NDVER and then
2nd) send an NDVER dispatch signal equal to the NDVER 5-minute curtailed output instruction (e.g. net of NDVER actual capability minus DCPL curtailed output).
Page 43 of 59
SPP can curtail this type of NDVER economically in SCED through DCPL deployment without having to issue NDVER OOME instruction. SPP shall not clear any NDVER-DCPL if self-curtailed or clear amounts beyond/below the SPP dispatch instruction. The following special modeling rules apply to a DCPL Resource.
(1) A NDVER-DCPL is a special type of Resource created to model registered curtailment settlement location linked with a host upgraded/dispatchable NDVER;
(2) A NDVER-DCPL is modeled in the Commercial Model with a separately defined Settlement Location from a NDVER that has been upgraded to be dispatchable. Thus, the NDVER-DCPL will have separate PNode or APNodes at an electrically equivalent location to the associated NDVER PNode or APNode location;
(3) A NDVER-DCPL is also included in the SPP Network Model as a load addition representing offered price of curtailment of the associate NDVER generation output;
(4) A NDVER-DCPL must have a corresponding NDVER at an electrically equivalent location;
(5) The NDVER must have telemetering installed as with DVER registration in which curtailment MW volumes can be measured by SPP settlement;
(6) The Market Participant must submit the real-time actual base NDVER output capability to SPP via SCADA on a 10-second basis
(7) The Market Participant must submit the real-time achieved curtailment of the SPP deployed NDVER-DCPL value to SPP via SCADA on a 10-second basis.
(8) SPP will issue a follow dispatch flag to all NDVERs that have deployed NDVER-DCPL curtailments. The SPP NDVER dispatch instruction will consist of the actual NDVER cleared curtailed output target during for the interval or the actual NDVER output capability during intervals in which the resource is not curtailed.
(9) For each interval, SPP will settle deployed NDVER-DCPL cleared curtailment load resulting from the SCED economic curtailment of an NDVER, if any, and will clear 0.0 MW for the NDVER-DCPL if not curtailed.
(10) The NDVER-DCPL is settled at a common bus electrically equivalent settlement locations with the NDVER LMP and MCP negated. NDVER-DCPLs can be deployed during emergency events or to avoid Regulation scarcity pricing.

6.1.1011.1 External Dynamic Resources
A Market Participant registers an EDR for the purposes of accounting for importing of Operating Reserve that is sourced external to the SPP BA. An External Dynamic Resource that is modeled in the Eastern Interconnection may either represent a single Resource or a fleet of Resources and is not subject to Energy dispatch, only clearing and deployment of the Operating Reserve products that the EDR is qualified to provide, except that an associated Dynamic Schedule for Energy may be used for the purposes of providing Regulation-Down Service which must be specified at registration. An EDR that is associated with a DC tie-line is modeled as a single Resource and may be available for Energy dispatch and/or Operating Reserve clearing which must be specified at registration.

G.8.1 Demand Response Resource (DRR) Cost for Behind the Meter Generation
Market Participants using behind the meter Resource as a DDR Resource should refer to the appropriate unit type defined in this manual to develop incremental cost,
G.8.2 DRR Cost for Demand Reduction
Demand Reduction is the actual reduction of load at the direction of SPP through the commitment and dispatch of as associated DRR. This could include the cycling of air conditioners or the shutdown of an industrial production process in order to reduce the load at a site. Incremental costs can include quantifiable opportunity costs associated with the reduction, net of related offsetting increases in usage. Typically, demand reduction would be registered as a Block Demand Response Resource but an industrial site that can control its load consumption on a real-time basis could register as a Dispatchable Demand Response Resource.
G.8.3 DRR Start-Up Cost
DRR Start-Up cost is the cost to shut down or curtail a load for a given period, which does not vary with output, or the start cost of a behind the meter Resource. Start costs for DRRs represented by behind the meter Resources are defined by unit type in this manual. Start-Up costs for DRRs representing load curtailment are not specifically defined but will be evaluated on a case by case basis when submitted as part of a Market Participants fuel cost policy for reasonableness.
Page 45 of 59
G.8.4 DRR Cost to Provide Spinning and/or Supplemental Reserves
Spinning Reserves from Demand Response Resources must be provided by equipment electrically synchronized to the system, and able to be fully deployed for the cleared amount within ten minutes upon request by SPP. The costs of spinning reserves from a DRR are the quantifiable incremental costs to reduce load by the offered amount within ten minutes. Incremental costs include shut down costs and opportunity costs.
G.8.5 DRR Cost to Provide Regulation
Regulation-Up and/or Regulation-Down from Dispatchable Demand Response Resources must be provided by equipment electrically synchronized to the system and able qualify for provision of regulation services. The costs of regulation from DDR Resources are the quantifiable incremental costs to reduce load by the offered amount within five minutes. Incremental costs include shut down costs and opportunity costs.
G.9 Non-Dispatchable Variable Energy Resource – Dispatch Curtailment Pseudo Load (NDVER-DCPL) NDVER-DCPL- NDVER curtailment load amount which is settled at the negated NDVER LMP or MCP price and is offered at a price at which the NDVER Market Participant is willing to accept economic curtailment of their NDVER.
G.9.1 NDVER-DCPL: SPP NDVER dispatch Curtailment Energy Cost Exposure
NDVER with unexpired Federal Government Production Tax Credits (PTCs) or unexpired Purchase Power Agreement (PPA) purchase contracts may include lost PTC revenue exposure or PPA buyer cost obligations associated with NDVERs within a registered NDVER-DCPL pseudo curtailment load mitigated energy or reserve offer. Lost revenues can include, but is not necessarily limited to, PTC lost revenue exposure or contractual PPA buyer cost obligations triggered by economic/reliability SPP dispatch.
NDVER Conversions to Dispatchable and Market Benefits:
The SPP MMU has made frequent claims there are significant benefits from NDVERs becoming dispatchable. Thus, for NDVERs that both register and offer NDVER-DCPL curtailments for the at least 95% of NDVER capacity, the MMU shall allow reasonable PTC revenue and contractual PPA seller/buyer cost obligations for any SPP economic/reliability dispatch.
Market Participant Release from Burden of Proof:
If the parties to NDVER PPA contract dispute the contractual terms for cost obligations when SPP economically/reliability dispatches an NDVER-DCPL, within reason, the MMU will allow such cost exposure into mitigated offers so that nether the owners/sellers/buyers placed with burden of proof for disputed contractual terms.

4.1.2.6 Non-Dispatchable Variable Energy Resource - Dispatch Curtailment Pseudo Load (NDVER-DCPL)
Market Participants managing Non-Dispatchable Variable Energy Resource (NDVER) resources may
also register a type of Demand Response Resource (DRR) called a Dispatch Curtailment Pseudo Load –
(NDVER-DCPL) so the MP can be paid by SPP for NDVER curtailments without SPP having to issue
an OOME instruction to the NDVER. The NDVER-DCPL will be modeled on a Common Bus to the
NDVER at a separate settlement location. The NDVER-DCPL represents SPP economic/reliability
curtailment of NDVER output referred here as 5-minute dispatchable. SPP will clear the NDVER-
DCPL based on MP submitted curtailment dispatch curves and a negated NDVER LMPi. If there is no
curtailment of the NDVER the NDVER-DCPL will have 0.0 cleared MWs based on the following
formula.
NDVER-DCPLk LMPi = (NDVERk LMP i ) ( -1 )
Additionally, MCP will be cleared by SPP in the same manner.
.NDVER-DCPLk MCP = (NDVERk MCP ) ( -1 )
NDVER-DCPLk curtailment loads are always linked with a host NDVERk representing the curtailment
Registering a NDVER-DCPL is strictly a voluntary for NDVER owners and MPs. However, the
NDVER must upgraded to dispatchable controls so the NDVER can accept a 5-minute dispatch
instruction from SPP, prior to registering the NDVER-DCPL. The following provides a simple example

how the NDVER-DCPL A and NDVER A works together to represent a NDVER curtailment and SPP
payment when there is NDVER curtailment.

NDVER-DCPLk curtailment loads are always linked with a host NDVERk representing the curtailment from
the actual NDVERk MW capability.
The cleared NDVER-DCPL MW quantity is calculated as follows.
NDVER-DCPLki = NDVERki MW capability – actual NDVERki MW output , where
i….dispatch interval, and
k…NDVER unit numbering

3.2 Mitigation Measures for Energy Offer Curves
Mitigated Energy Offer Curves shall be submitted on a daily basis by the Market Participant in
accordance with the mitigated offer development guidelines in the Market Protocols. For Multi-
Configuration Resources (“MCR”), as defined in Attachment AE, for which a single configuration
allows physical units to be swapped (e.g., Combustion Turbine 2 for Combustion Turbine 1), the
costs used in the mitigated offer development for that configuration shall be those of the least cost
physical unit that is available and can be swapped in such configuration. The mitigated Energy
Offer Curve may be updated up to the close of the Day-Ahead Market as defined in Section 5.1 of
Attachment AE of this Tariff for use in the Day-Ahead Market. In the case a Resource is not
committed by the Day-Ahead Market, the mitigated Energy Offer Curve may be updated until the
Day-Ahead RUC begins. For Resources committed by the Day-Ahead Market, the mitigated
Energy Offer Curve submitted as of the close of the Day-Ahead Market will apply to the Day-
Ahead Market on the day before the Operating Day and the RTBM on the Operating Day; for all
other Resources the mitigated Energy Offer Curve submitted at the time the Day-Ahead RUC
begins will apply to the Day-Ahead RUC on the day before the Operating Day, and the Intra-Day
RUC processes and the RTBM on the Operating Day.
A. The Energy Offer Curve conduct thresholds are as follows:
(1) For Resources committed to address a Local Reliability Issue, the conduct threshold
is a 10% increase above the mitigated Energy Offer Curve;
Page 56 of 59
(2) For Resources located in a Frequently Constrained Area and not subject to Section
3.2(A)(1), the conduct threshold is a 17.5% increase above the mitigated Energy
Offer Curve;
(3) For all other Resources the conduct threshold is a 25% increase above the mitigated
Energy Offer Curve.
B. The Transmission Provider shall apply mitigation measures by replacing the Energy Offer
Curve with the mitigated Energy Offer Curve if:
(1) The Resource’s Energy Offer Curve exceeds the mitigated Energy Offer Curve by
the applicable conduct threshold; and
(2) The Resource has local market power as determined in Section 3.1; and
(3) The Resource either:
(a) Fails the Market Impact Test as described in Section 3.7, or
(b) Is manually committed by the Transmission Provider or by a local
transmission operator.
An Energy Offer below $25/MWh will not be subject to mitigation measures for economic
withholding.
C. The mitigated energy offer shall be the Resource’s short-run marginal cost of producing
energy as determined by the unit’s heat rate; fuel costs and the costs related to fuel usage,
such as transportation and emissions costs (“total fuel related costs”); and Energy Offer
Curve (“EOC”) variable operations and maintenance costs (“VOM”) as detailed in the
Market Protocols.
D. Opportunity cost shall be an estimate of the Energy and Operating Reserve Markets
revenues net of short run marginal costs for the marginal forgone run time during the
timeframe when the Resource experiences the run-time restrictions as detailed in the
Market Protocols. The run-time restrictions shall be updated as specified in the Market
Protocols, with more frequent updating to occur the fewer hours that remain available,
consistent with the Market Protocols. The Market Participant may include in the
calculation of its mitigated Energy Offer Curve an amount reflecting the resource-specific
opportunity costs expected to be incurred under the following circumstances:
(1) Externally imposed environmental run-hour restrictions; or
(2) Physical equipment limitations on the number of starts or run-hours, as verified by
the Market Monitoring Unit and determined by reference to the manufacturer’s
Page 57 of 59
recommendation or bulletin, or a documented restriction imposed by the applicable
insurance carrier; or
(3) Fuel Supply Limitations.
Resource specific opportunity costs are calculated by forecasting Locational Marginal
Prices based on futures contract prices for natural gas and the historical relationship
between the SPP system marginal Energy component of LMP and the price of natural gas,
as determined by the SPP Market Monitoring Unit. The formulas and instructions in the
price forecast model shall be determined by the SPP Market Monitoring Unit and published
in the Market Protocols as part of the Mitigated Offer Development Guidelines, updated,
as needed, by the SPP Market Monitoring Unit. Such forecasts of LMPs shall take into
account historical variability, and basis differentials affecting the Settlement Location at
which the Resource is located for the three-year period immediately preceding the period
of time in which the Resource is bound by the referenced restrictions, and shall subtract
therefrom the forecasted costs to generate energy at the Settlement Location at which the
Resource is located, as specified in more detail in Appendix G of the Market Protocols. If
the difference between the forecasted Locational Marginal Prices and forecasted costs to
generate energy is negative, the resulting opportunity cost shall be zero. The Market
Monitoring Unit will verify all Market Participants’ opportunity cost calculations for
consistency and accuracy. When the Market Monitoring Unit determines that the market
price for any period was not competitive, it will adjust the LMP forecasting process used
in the opportunity cost calculations to ensure that forecasted LMPs do not reflect non-
competitive market conditions.
The following formula shall apply to all mitigated Energy Offer Curves:
Mitigated Energy Offer ($/MWh) = HeatRate (mmBtu/MWh) *
Performance Factor * Total Fuel Related Costs ($/mmBtu) + EOC VOM ($/MWh) + Opportunity
Costs ($/MWh)
The Market Participant shall submit heat rate curves, descriptions of how spot fuel prices and/or
contract prices are used to calculate fuel costs, variable fuel transportation and handling
costs, emissions costs, and VOM to the Market Monitoring Unit. All cost data and cost
calculation descriptions are subject to the review and approval of the SPP Market
Monitoring Unit to ensure reasonableness and consistency across Market Participants. The
Page 58 of 59
information will be sufficient for replication of the mitigated Energy Offer Curve and shall
include, among other data, the following information:
(1) For fuel costs, Market Participants shall provide the Market Monitoring Unit with
an explanation of the Market Participants’ fuel cost policy, indicating whether fuel
purchases are subject to a fixed contract price and/or spot pricing and specifying
the contract price and/or referenced spot market prices. Any included fuel
transportation and handling costs must be short-run marginal costs only, exclusive
of fixed costs.
(2) For emissions costs, Market Participants shall report the emissions rate of each of
their units and indicate the applicable emissions allowance cost.
(3) For VOM costs, Market Participants shall submit VOM costs, calculated in
adherence with the Appendix G of the Market Protocols, reflecting short-run
marginal costs, exclusive of fixed costs.
Further details associated with the development, validation, and updating of these costs are
included in Appendix G of the Market Protocols.
For Demand Response Resources utilizing Behind-The-Meter Generation, the mitigated
Energy Offer Curve shall be developed in the same manner as any other generating
Resource as described above. For Demand Response Resources utilizing load reduction,
the mitigated Energy Offer Curve shall reflect the quantifiable opportunity costs associated
with the reduction, net of related offsetting increases in usage.
For Dispatchable Variable Energy Resources, the mitigated Energy Offer Curve may
include, but shall not exceed, any quantifiable costs that vary by MWh output, including
short-run incremental VOM. Mitigation will not apply to Non-Dispatchable Variable
Energy Resources in the Real-Time Balancing Market; monitoring of Energy Offers for
Non-Dispatchable Variable Energy Resources will occur.
E. Intra-day changes to the mitigated Energy Offer Curve are allowed under the following
conditions:
1) In the event that the Transmission Provider requests that a Resource remain online
past their commitment period by the Day-Ahead Market or a RUC process, the
Market Participant may submit an updated mitigated energy offer curve that reflects
the procurement of higher cost fuel;
2) A Resource must switch fuels due to unforeseen operating conditions; or
Page 59 of 59
3) A Market Participant employing the Quick-Start Resource logic as described in the
Market Protocols may update its mitigated Energy Offer Curve after the Day-Ahead
RUC clears on the day before the Operating Day, as described in Appendix G of
the Market Protocols.
Intra-day changes to the mitigated energy offer curve must follow the mitigated offer
development guidelines in Appendix G of the Market Protocols. Any such changes will be
validated by the Market Monitor.
F. In all cases under this Section 3.2, cost data submitted for the development of mitigated
offers, including opportunity cost data, shall be subject to the confidentiality provisions set
forth in Section 11 of Attachment AE of this Tariff.

OBJECTIVE OF REVISION
Page 3 of 9
Objectives of Revision Request:
Describe the problem/issue this revision request will resolve.
SPP has shown that NDVERs chasing price signals can result in significant costs to the market, can create reliability concerns, and has stated that more dispatchable units would improve market efficiency. Therefore, SPP has proposed 100 percent conversion of NDVERs to DVERs. Sunflower does not oppose this approach and believes that in the majority of cases conversion is good for both the market and the market participant. However, Sunflower is sympathetic to the fact that in certain cases, there is little benefit of conversion to the market or the market participant. Examples of these cases may include smaller Type I or Type II units that would require substantial $/MW to convert, or farms located in areas that rarely see negative prices (and therefore would rarely be subject to curtailment). A full conversion requirement would potentially result in an MP wasting money on a needless conversion or the MP requesting an exemption from FERC. If the exemption were granted, the concern of exempted NDVERs chasing price would still exist. This RR is not mutually exclusive to the SPP proposal since it would fix the concern of exempted NDVERs chasing price.
Describe the benefits that will be realized from this revision.
This RR would: Strongly discourage NDVERs from chasing price signals (or at least encourage slow output changes) which would increase market efficiency and reliability. Not require any subjective monitoring or threat of FERC referral since “price chasing” is not specifically prohibited. Allow MPs to make the decision to convert from NDVER to DVER based on business case and financial analysis. Encourage conversion of NDVERs to DVERs where it provides the most benefit to the market and the MP.
Basic design
This RR proposes using the existing URD logic (or slight derivation thereof) in the settlements system to impose substantial penalties on NDVERs whose output varies more than 5 percent (subject to the same 20MW cap and 5MW floor values currently applicable to URDs) from “setpoint”. The “setpoint” would be equal to the previous dispatch interval average output or (optionally) the current dispatch intervals average real-time capability sent to SPP via ICCP. There would be no change to existing OOME and/or Reliability Curtailments.
If the deviation from “setpoint” exceeds 5 percent, the charge for each 5 minute interval would be equal to the deviation MW * $1000, where the deviation is defined as the lessor of The Absolute Value of (The Previous 5 minute interval average output – The Current 5 minute interval average output) or The Absolute Value of (The Current 5 minute interval average real-time capability – The Current 5 minute interval average output). Penalties collected are credited to TCR funding.
NdverUrd5MinQty = MIN ( ABS (RtBillMtr5MinQtya,s,i-1 - RtBillMtr5MinQtya,s,i),
ABS (RtCap5MinQtya,s,i - RtBillMtr5MinQtya,s,i ) ) Examples
o MP chooses NOT to convert to DVER and DOES NOT send real-time capability to SPP via ICCP. This option requires no change or investment for the MP, and may make sense if the MP never plans to curtail the unit and isn’t concerned about some exposure to inadvertent penalties due to abrupt changes in wind speed or direction.
If the output of the NDVER does not change by more than 5 percent from 1 interval to the next, there will be no penalty and should have minimal negative impact on the market.
• This should happen most of the time that the NDVER is strictly following the wind.
• This would also happen if the NDVER is manually curtailed at a rate less than 1percent/min. This gives the NDVER the ability to follow price to some degree without penalty at a rate that should be manageable by SPP.
If the output of the NDVER does change by more than 5 percent from 1 interval to the next, a penalty will be assessed as defined above due to the potential for significant negative impact on the market.
• This would also happen if the NDVER is manually curtailed at a rate greater than 1percent/min. This still allows the NDVER the ability to follow price as quickly as desired, though penalties for doing so could be substantial, especially if the NDVER is cycling up and down.
• This could happen when the NDVER is strictly following the wind and the wind speed or direction changes abruptly (which may happen when a weather front moves through for example).
Page 4 of 9
o MP chooses NOT to convert to DVER and DOES send real-time capability to SPP via ICCP. This option requires some (likely minimal) investment for the MP to send the real-time capability signal to SPP. This may make sense if MP never plans to curtail the unit and wants protection against inadvertent penalties.
If the output of the NDVER does not change by more than 5 percent from 1 interval to the next OR does not deviate by more than 5percent from the real-time capability for the current interval, there will be no penalty and should have minimal negative impact on the market.
• This should happen all of the time that the NDVER was strictly following the wind. Sudden changes in wind speed or direction should be reflected in the real-time capability, and no penalty would be assessed.
• This would also happen if the NDVER is manually curtailed at a rate less than 1 percent/min. This gives the NDVER the ability to follow price to some degree without penalty at a rate that would be manageable by SPP.
If the output of the NDVER does change by more than 5 percent from 1 interval to the next AND deviates by more than 5 percent from the real-time capability for the current interval, a penalty will be assessed as defined above due to the potential for significant negative impact on the market.
• This should only happen if the NDVER is manually curtailed at a rate greater than 1 percent/min. This allows the NDVER the ability to follow price as quickly as desired, though penalties for doing so could be substantial, especially if the NDVER is cycling up and down..
o MP chooses to convert NDVER to DVER. This option would require some (which could vary widely from one wind farm to another) investment to receive and follow a setpoint from SPP. This would make sense if the wind farm were located in an area that frequently saw negative LMPs and the cost to convert was not astronomical.
None of the penalties described in this RR would apply. Unit would be subject to penalties that currently apply to existing DVERs.
SPP would economically dispatch the unit resulting in maximum benefits to the market and MPs.

Market Protocols
4.4.4.1 Uninstructed Resource Deviation
The following rules apply to the calculation of Uninstructed Resource Deviation (URD).
(1) URD is the difference between a Resource’s actual average MW output over the Dispatch Interval and the Resource’s average ramped MW Setpoint Instruction over a Dispatch Interval. For the purposes of determining URD exemptions for Resources that are part of a Common Bus as described under Section 4.4.4.1.1(6), each Asset Owner’s Resources’ combined average ramped MW Setpoint Instruction and combined actual average MW output at the Common Bus will be used to calculate URD at the Common Bus for the Dispatch Interval for each Asset Owner;
(2)(1) A Resource’s URD is allocated a portion of the RUC Make Whole Payment costs in any Dispatch Interval where Resource’s URD is outside of its Operating Tolerance unless that Resource has been exempted from URD under Section 4.4.4.1.1.
Field Code Changed
Page 5 of 9
(a) A generating unit Resource’s Operating Tolerance in each Dispatch Interval is equal to the Resource’s Maximum Emergency Capacity Operating Limit multiplied by 5%, subject to a minimum of 5 MW and a maximum of 20 MW.

(c) A Block Demand Response Resource’s Operating Tolerance in each Dispatch Interval is equal to the Resource’s Maximum Economic Capacity Operating Limit multiplied by 5%, subject to a minimum of 5 MW and a maximum of 20 MW.
(d) The Common Bus Operating Tolerance for each Asset Owner registered at a Common Bus is equal to the sum of that Asset Owner’s Resources’ Maximum Emergency Capacity Operating Limits for Resources that are on-line multiplied by 5%, subject to a minimum of 5 MW and a maximum of 20 MW.
(e) A non-NDVER Resource’s URD is allocated a portion of the RUC Make Whole Payment costs in any Dispatch Interval where Resource’s URD is outside of its Operating Tolerance unless that Resource has been exempted from URD under Section 4.4.4.1.1.
(a) If the absolute value of a non-NDVER Resource’s URD is greater than the Resource’s Operating Tolerance in any Dispatch Interval, the Resource URD / 12 is included in the hourly allocation of RUC Make Whole Payment cost allocation. The hourly URD amount is calculated as the sum of Dispatch Interval URD for the hour. See Section 4.5.9.10 for calculation details. Additionally, if that Resource was eligible to receive a RUC Make Whole Payment, the payment may be reduced. See Section 4.5.9.8 for calculation details.
(3)(2) A NDVER Resources URD is assessed a penalty that is allocated to TCR funding in any Dispatch Interval where Resource’s URD is outside of its Operating Tolerance unless that Resource has been exempted from URD under Section 4.4.4.1.1
(a) If the absolute value of a NDVER Resources URD is greater than the Resource’s Operating Tolerance in any Dispatch Interval, the Resource will be assessed the Resources URD * NDVER Penalty.
i. The NDVER Resources URD shall be defined to be the lesser of the absolute value of: Previous Dispatch Interval MW Output – Current Dispatch Interval MW Output; or Actual SCADA Current Dispatch Interval Average Capability – Current Dispatch Interval MW Output. See Section 4.5.9.14 for calculation details.
ii. The NDVER Penalty amount shall be decided by the MWG and reviewed annually or more often if needed.

4.5.8.14 Transmission Congestion Rights Funding Amount
(1) The Transmission Congestion Rights Funding Amount can be either a credit or charge to an Asset Owner and is calculated for each TCR instrument held by the Asset Owner and NDVER URD Penalty. TCR instruments will be fully funded in each hour. The amount to each Asset Owner (AO) for each TCR instrument for a given hour of the Operating Day is calculated as follows:
#TcrFundHrlyAmt a, h =
∑t
(TcrHrlyQty a, h, t * (DaMccHrlyPrc source, h - DaMccHrlyPrc sink, h ) ) +
∑t
( NdverUrd5MinQty a, s ,i ) * NdverPenalty
(a) Where: NdverUrd5MinQty = MIN ( ABS (RtBillMtr5MinQtya,s,i-1 - RtBillMtr5MinQtya,s,i), ABS (RtCap5MinQtya,s,i - RtBillMtr5MinQtya,s,i ) )
(2) For each Asset Owner associated with Market Participant m, a daily amount is calculated. The daily amount is calculated as follows:
TcrFundAoAmt a, m, d = ∑h
TcrFundHrlyAmt a, h
(3) For each Market Participant, a daily amount is calculated representing the sum of Asset Owner amounts associated with that Market Participant. The daily amount is calculated as follows:
TcrFundMpAmt m, d = ∑a
TcrFundAoAmt a, m, d
4.5.9.10 RUC Make Whole Payment Distribution Amount
(1)(a.8) In any Dispatch Interval in which a non-NDVER Resource operates outside of its Operating Tolerance and the Resource has not been exempted from URD per Section 4.4.4.1, one-twelfth of the Absolute Value of the Resource’s Uninstructed Resource Deviation is included as a deviation. An Asset Owner’s URD deviation is calculated as follows.

i. The NDVER Resources URD shall be defined to be the lesser of the absolute value of: Previous Dispatch Interval MW Output – Current Dispatch Interval MW Output; or Actual SCADA Current Dispatch Interval Average Capability – Current Dispatch Interval MW Output.
ii. The NDVER Penalty amount shall be decided by the MWG and reviewed annually or more often if needed.
8.5.11 Transmission Congestion Rights Funding Amount
The TCR funding amount can be either a charge or a payment to an Asset Owner and is calculated
for each TCR instrument held by the Asset Owner and NDVER Penalty. The TCR instruments funding
amount is calculated for each hour as follows:
TCR Hourly Funding Amount =
TCR Hourly Quantity * [(Day-Ahead MCC at the source) – (Day-Ahead MCC at the sink)] +
NDVER Penalty Hourly Quantity
(1) Day Ahead MCC is as defined under Section 1 of this Attachment AE.
(2) TCR Hourly Quantity is the amount TCR MWs held on a particular source to sink path as awarded
to that Asset Owner in the annual TCR auction, monthly TCR auctions or secondary market as
described under Section 7 of the Attachment AE.
(3)_ NDVER Penalty calculations are defined in the Integrated Market Protocols.

RR Title: NDVER to DVER Conversion Through URD

OBJECTIVE OF REVISION
Objectives of Revision Request:
Describe the problem/issue this revision request will resolve.
SPP has shown that NDVERs chasing price signals can result in significant costs to the market, can create reliability concerns, and has stated that more dispatchable units would improve market efficiency. Therefore, SPP has proposed 100 percent conversion of NDVERs to DVERs. Sunflower does not oppose this approach and believes that in the majority of cases conversion is good for both the market and the market participant. However, Sunflower is sympathetic to the fact that in certain cases, there is little benefit of conversion to the market or the market participant. Examples of these cases may include smaller Type I or Type II units that would require substantial $/MW to convert, or farms located in areas that rarely see negative prices (and therefore would rarely be subject to curtailment). A full conversion requirement would potentially result in an MP wasting money on a needless conversion or the MP requesting an exemption from FERC. If the exemption were granted, the concern of exempted NDVERs chasing price would still exist. This RR is not mutually exclusive to the SPP proposal since it would fix the concern of exempted NDVERs chasing price.
Describe the benefits that will be realized from this revision.
This RR would: Strongly discourage NDVERs from chasing price signals (or at least encourage slow output changes) which would increase market efficiency and reliability. Not require any subjective monitoring or threat of FERC referral since “price chasing” is not specifically prohibited. Allow MPs to make the decision to convert from NDVER to DVER based on business case and financial analysis. Encourage conversion of NDVERs to DVERs where it provides the most benefit to the market and the MP.
Basic design
This RR proposes using the existing URD logic (or slight derivation thereof) in the settlements system to impose substantial penalties on NDVERs whose output varies more than 5 percent (subject to the same 20MW cap and 5MW floor values currently applicable to URDs) from “setpoint”. The “setpoint” would be equal to the previous dispatch interval average output or (optionally) the current dispatch intervals average real-time capability sent to SPP via ICCP. There would be no change to existing OOME and/or Reliability Curtailments.
If the deviation from “setpoint” exceeds 5 percent, the charge for each 5 minute interval would be equal to the deviation MW * $1000, where the deviation is defined as the lessor of The Absolute Value of (The Previous 5 minute interval average output – The Current 5 minute interval average output) or The Absolute Value of (The Current 5 minute interval average real-time capability – The Current 5 minute interval average output). Penalties collected are credited to TCR funding.

ABS (RtCap5MinQtya,s,i - RtBillMtr5MinQtya,s,i ) ) Examples
o MP chooses NOT to convert to DVER and DOES NOT send real-time capability to SPP via ICCP. This option requires no change or investment for the MP, and may make sense if the MP never plans to curtail the unit and isn’t concerned about some exposure to inadvertent penalties due to abrupt changes in wind speed or direction.
If the output of the NDVER does not change by more than 5 percent from 1 interval to the next, there will be no penalty and should have minimal negative impact on the market.
• This should happen most of the time that the NDVER is strictly following the wind.
• This would also happen if the NDVER is manually curtailed at a rate less than 1percent/min. This gives the NDVER the ability to follow price to some degree without penalty at a rate that should be manageable by SPP.
Page 2 of 3
If the output of the NDVER does change by more than 5 percent from 1 interval to the next, a penalty will be assessed as defined above due to the potential for significant negative impact on the market.
• This would also happen if the NDVER is manually curtailed at a rate greater than 1percent/min. This still allows the NDVER the ability to follow price as quickly as desired, though penalties for doing so could be substantial, especially if the NDVER is cycling up and down.
• This could happen when the NDVER is strictly following the wind and the wind speed or direction changes abruptly (which may happen when a weather front moves through for example).
o MP chooses NOT to convert to DVER and DOES send real-time capability to SPP via ICCP. This option requires some (likely minimal) investment for the MP to send the real-time capability signal to SPP. This may make sense if MP never plans to curtail the unit and wants protection against inadvertent penalties.
If the output of the NDVER does not change by more than 5 percent from 1 interval to the next OR does not deviate by more than 5percent from the real-time capability for the current interval, there will be no penalty and should have minimal negative impact on the market.
• This should happen all of the time that the NDVER was strictly following the wind. Sudden changes in wind speed or direction should be reflected in the real-time capability, and no penalty would be assessed.
• This would also happen if the NDVER is manually curtailed at a rate less than 1 percent/min. This gives the NDVER the ability to follow price to some degree without penalty at a rate that would be manageable by SPP.
If the output of the NDVER does change by more than 5 percent from 1 interval to the next AND deviates by more than 5 percent from the real-time capability for the current interval, a penalty will be assessed as defined above due to the potential for significant negative impact on the market.
• This should only happen if the NDVER is manually curtailed at a rate greater than 1 percent/min. This allows the NDVER the ability to follow price as quickly as desired, though penalties for doing so could be substantial, especially if the NDVER is cycling up and down..
o MP chooses to convert NDVER to DVER. This option would require some (which could vary widely from one wind farm to another) investment to receive and follow a setpoint from SPP. This would make sense if the wind farm were located in an area that frequently saw negative LMPs and the cost to convert was not astronomical.
None of the penalties described in this RR would apply. Unit would be subject to penalties that currently apply to existing DVERs.
SPP would economically dispatch the unit resulting in maximum benefits to the market and MPs.
COMMENTS
NPPD discussion items for RR274:
- What about other units that are outside the Resources URD thresholds? Shouldn’t they face the same penalty? NPPD believes all Units should be treated equally.
- Resources at times cannot stay within URD thresholds. This could be due to many different events or issues outside their control. This RR would have an NDVER get penalty costs for an event while other units would not for events outside their control. Renewables can change quickly at times due to Mother Nature and to subject them to penalties seems unreasonable.
- Some sites may not have the ability or will have costs to get real-time capability to SPP via ICCP from some resources.
- The RR states there is a benefit to the market to convert NDVERs to DVERs. If there are costs of converting from an NDVER to a DVER for that Resource there should be a way to mitigate the costs for that resource by the SPP IM Market.

COMMENTS Provide the objective language from the revision request for which you are submitting comments. … the fact that in certain cases, there is little benefit of conversion to the market or the market participant.

A full conversion requirement would potentially result in an MP wasting money on a needless conversion or the MP requesting an exemption from FERC.
Olympus Power, LLC owns an existing wind farm located in a SPP area that routinely experiences negative pricing. Our wind farm consists of 80 – 1.0 MW, Mitsubishi MWT-100-61 machines (Type I generator) and has been operational since December 2001 with a long term PPA that expired on December 31, 2016. We have reviewed RR #274 and found it to be very restrictive given the age of our equipment and existing support systems. According to our wind consultants, the economic cost to comply with the proposed setpoint and curtailment standards (along with the extremely high deviation penalties) would entail costly upgrades to the SCADA system, programing changes and even the installation of an energy storage device(s) (Estimated to be $45M). Given that our windfarm is subject to the SPP open market pricing, ANY of the above changes would cause serious economic burden, when we are receiving very low around the clock pricing and not generating any PTC’s. Further, the true cause of any negative pricing scenarios is the proliferation of new Type-III and Type IV wind farms in our area, that are producing PTC’s. This needs to be addressed first.
Once again, foisting this change of 100 percent conversion of NDVERs to DVERs onto us and similar (age of the farm and equipment) wind farms is not economically feasible to a long standing/existing SPP power supplier.

Finally Type-I and Type-II wind farms should have an exception in the Protocols of RR#274, which avoids having to file an exception with FERC (very costly process).
Multi-Day Minimum Run Time Gaming Issue (Options 1 & 2)Market Working Group (MWG)
February 6-7, 2018
Debbie James
Background• Potential gaming issue Resource with minimum run time greater than 24 hours can
increase energy offers at minimum and/or no-load offers Resource would not be decommitted and could receive make
whole payments (MWPs) to higher offers
• Staff presented potential options at October and November 2017 MWG meetings Option 1 (No MWP after 24 Hours) Option 2 (Binding Offer at Min. Energy for Min. Run Time) Option 3 (Offer Validation Cap) Option 4 (Mitigated Offer used for MWP after Initial
Commitment)
• MWG furthered reviewed Options 1 and 2, as well as a new option proposed by OGE at January meeting MMU identified a concern with the OGE option
2
OGE Option: MWP after 24 Hours becomes lesser of Mitigated Offer or Energy Offer for balance of Minimum Run Time• Resource receives commitment for entirety of its minimum run
time
• “As-Committed” start-up, no-load and energy offers used for DAMKT MWP for first 24 hours MWPs after first 24 hours of minimum run time will revert to
lesser of Mitigated Offer or Energy Offer for balance of minimum run time.
• “As-Committed” start up, no-load and energy at minimum offers will be used for RUC MWPs for first 24 hours. MWPs after first 24 hours of minimum run time will revert to
lesser of Mitigated Offer or Energy Offer for balance of minimum run time.
• All parameters of MWP remain same only change is to use mitigated cost or below cost energy offers as opposed to energy offers above a resource’s cost.
• Gaming opportunity for price changing after commitment is removed because resource is at best made whole to cost after initial 24 hour commitment.
3
MMU Concern with OGE Option• This option trades one loophole for another Uneconomical Resources that are normally self-committed
could change commit status to ‘market’ MPs could submit a below cost Resource offer in order to
appear economic and receive a market commitment On the first day, they would be a price-taker just like they
were when they self-committed On subsequent days, they would be eligible for MWPs at their
mitigated offer
• MWPs are based on costs that are different than the costs used during the commitment decision This is a similar, but different, form of gaming that we are
currently trying to stop Allows for guaranteed cost recovery for any Resource, with
the exception of the first day
4
Option 1: No MWP After 24 Hours
• MPs do not receive MWPs after 24 hours for duration of minimum run time MPs can submit a minimum run time greater than 24 hours MWP for start up, no-load, energy and OR allowed for first 24
hours
• “As-committed” start-up, no-load and energy offers will be used for DAMKT for first 24 hours
• “As-committed” start up, no-load and energy at minimum will be used for RUC MWPs for first 24 hours
• Medium cost to implement
5
Option 1: MMU Concerns
• Option could lead to suppressed real-time prices MPs are incentivized to offer untrue offer parameters to
attempt to receive MWPs for each day MPs could attempt to get a market commitment each day by
submitting 24 min runtime or less in the DAMKT, regardless of their actual min runtime
If not committed in the DAMKT, they could self-commit in the DARUC to meet their real physical parameters
Leads to over-commitment in real-time which suppresses prices
6
Option 2: Binding Offer at Minimum Energy for Minimum Run Time
• Resource receives commitment for entirety of its minimum run time
• “As-Committed” start-up, no-load and energy offers used for DAMKT MWPs MWPs based on lower of “as-committed” or effective offer
for duration of minimum run time
• “As-Committed” start up, no-load and energy at minimum offers will be used for RUC MWPs MWPs based on lower of “as-committed or effective offer for
duration of minimum run time
• Submitted resource offers will be used for dispatch and clearing
• If MP changes minimum economic operating limit after commitment, they will not receive a MWP
• High/Medium cost to implement 7

OBJECTIVE OF REVISION
Objectives of Revision Request: Describe the problem/issue this revision request will resolve.
The Operating Criteria Review Task Force is a joint effort between ORWG and RCWG to perform a wholesale review of SPP Operating Criteria with an emphasis on removing antiquated language and modernizing remaining language. In many cases, the current SPP Operating Criteria contains many redundancies with NERC Reliability Standards. Some portions of SPP Operating Criteria were written approximately two decades ago resulting in a need to modernize the language.
This Revision Request represents the culmination of the OCRTF’s efforts in revising SPP Operating Criteria Appendices. This Revision Request also proposes the creation of the stand-alone ‘SPP Reliability Coordinator Outage Coordination Methodology’ using the current content of Appendix OP-2 as the basis.
Describe the benefits that will be realized from this revision.
By removing antiquated language and modernizing remaining language, the efforts of the OCRTF will result in SPP Operating Criteria that most accurately represents the requirements needed for SPP to perform the Reliability Coordinator, Balancing Authority, Transmission Service Provider, and Reserve Sharing Group.
The creation of the stand-alone ‘SPP Reliability Coordinator Outage Coordination Methodology’ will further ensure consistency in using stand-alone documents where necessary to meet certain requirements in NERC Reliability Standards.
REVISIONS TO SPP DOCUMENTS In the appropriate sections below, please provide the language from the current document(s) for which you are requesting revision(s), with all edits redlined.

Purpose
The purpose of this methodology is to provide technical requirements and criteria to Transmission Operators, Generator
Operators and SPP Staff related to submission of Transmission and Generation outages to the SPP Reliability Coordinator
and SPP Balancing Authority via the SPP CROW tool. Outage submissions will be shared with other Reliability
Coordinators, Transmission Operators, and Balancing Authorities via the NERC System Data Exchange (SDX) and will be
used for assessing real-time and future reliability of the Bulk Electric System. Transmission and generation operators are
responsible for submitting all outages through the CROW tool. All other transmission operators will be able to view and
identify all outages that are submitted through CROW. SPP reserves the right to approve, deny, or reschedule any
outage deemed necessary to ensure system reliability on a case by case basis regardless of date of submission.
1. Transmission Outages and Operations
For the purpose of identifying applicable facilities, the nominal kV level of the facility will be used. For transformers,
use the low side voltage class. Example: A 161/69kV transformer shall be classified as a 69kV facility for the
purposes of this methodology.
a. Forced Transmission Outage Submission Requirements
Forced outages of all transmission facilities greater than 60kV that are modeled in the SPP regional models
and have been modeled in the CROW tool should be submitted within 30 minutes or as soon as practical
after the outage. Each outage submission must be accompanied by a Planned End Time, Forced Outage
Priority, an associated Outage Request Type, and an Outage Cause. Forced Outage Priory outages will be
considered Non-Recallable. At the time of submission, forced outage reasons may not be known so a reason
of Unknown may be selected. It is recognized that the duration of a forced outage will typically not be
known at the time of the initial submission. The Planned End Time should be the best estimate for the
return of the outaged facility. Any known updates to the Planned End Time and/or reason for the outage
shall be submitted promptly to the CROW tool.
b. Scheduled Transmission Outage Submission Requirements
Scheduled outages of all BES elements must be submitted to the CROW tool and approved by the Reliability
Coordinator prior to implementing the outage. Scheduled outages of all other transmission elements
Page 4 of 25
greater than 60kV that are modeled in the SPP regional models must be submitted to the Reliability
Coordinator’s CROW tool for coordination and review. Each outage submission must be accompanied by a
Planned Outage Start Time and Planned End Time, Outage Priority, Outage Request Type, and Outage Cause.
Each outage request must also be designated as Non-Recallable, or provide an expected Recall time if
directed. Sufficient notation in the outage scheduler “Requestor Notes” comment field should include a
description or explanation for the outage. An incomplete outage request of any missing data could result in
the outage being denied. Once the actual outage takes place, the Actual Start Time of the outage must be
submitted to the CROW tool. When the outage has ended, the Actual End Time of the outage must be
updated.
c. Transmission Outage Priority and Timing Requirements
Each Transmission Outage submitted must include one of the following Outage Priorities. Forced outages of
equipment must be submitted with a Priority of Forced as defined below. The CROW Outage Scheduler will
enforce the lead time requirements of each Outage Priority. Outages that are not planned will have a lower
priority and may not be approved by the RC. Outages not submitted as planned will be reviewed and
approved by SPP on a case-by-case basis. The risk of imminent equipment failure will have priority over
other outages including planned. If sufficient time is not available to analyze the request then the outage
will be denied.
Priority Definition Minimum
Lead Time
Maximum
Lead Time
Planned Equipment is known to be operable with little risk of leading to a forced
outage. As required for preventive maintenance, troubleshooting, repairs that
are not viewed as urgent, system improvements such as capacity upgrades, the
installation of additional facilities, or the replacement of equipment due to
obsolescence.
14 Calendar
Days
None
Discretionary Equipment is known to be operable with little risk of leading to a forced
outage; however the timeline for submission of Planned outage priority has
passed. Discretionary outages are required to be submitted at least 2 calendar
days in advance. Due to the shorter lead time, this outage priority has
increased risk of being denied based upon higher priority outage requests.
2 Days 14
Calendar
Days
Opportunity Lead time may be very short or zero. An outage that can be taken due to
changed system conditions (ie Generator suddenly offline for forced outage
allows transmission work to be done).
None 7 Days
Operational Equipment is removed from service for operational reasons such as voltage
control, constraint mitigation as identified in an operating procedure, etc.
None None
Urgent Equipment is known to be operable, yet carries an increased risk of a forced
outage or equipment loss. The equipment remains in service until
maintenance crews are ready to perform the work.
2 Hours 48 Hours
Page 5 of 25
Emergency Equipment is to be removed from service by operator as soon as possible
because of safety concerns or increased risk to grid security.
None 2 Hours
Forced Equipment is out of service at the time of the request. None 1 Hour
d. Transmission Outage Equipment Request Types
Each Transmission outage (scheduled and forced) request submitted must include one of the following
Outage Request Types.
Outage Request Type Definition Modeling Assumptions
Out of Service (OOS) Equipment is out of service. SDX = Open
EMS = Open
Normally Open (NO) Equipment is normally out of service and is identified as normally open in
the SPP regional models. Normally Open request type is used to close
(place in service) a normally open facility.
SDX = Closed
EMS = Closed
Informational (INF) Used for outage events that are not covered by one of the other Outage
Equipment Request Types. Not an out of service event.
None – Informational Only
Hot Line Work (HLW) Work is being performed on live or energized equipment. None – Informational Only
General System
Protection (GSP)
Work is being performed on protection systems. Requestor shall
specifically identify protection systems out of service and any
modification to operation or behavior of system contingencies.
None – Informational Only
e. Transmission Outage Request Reasons/Causes
Each Transmission Outage Request must be submitted with one of the following reasons for the outage.
Reason/Cause Definition
Maintenance & Construction Outages to facilitate repair, maintain, or upgrade of facility related equipment. This includes
clearances to perform vegetation management. Does not include outages to support Maintenance &
Construction of other facilities. Those should be submitted as Voltage or SOL Mitigation.
Third Party Request Non-transmission facility related requests for clearance or work such as highway construction.
Voltage Mitigation Operation of facilities to preserve or correct Bulk Electric System voltage.
SOL Mitigation (Thermal) Operation of facilities to preserve or correct Bulk Electric System thermal loading issues.

thermal loading due to other contingencies, transient stability conditions, etc.
Unknown Operation of facilities due to an unknown reason. Most forced outages will be submitted with an
initial reason of Unknown. Once the actual reason for the operation is known, the outage requestor
should update the outage request. SPP Staff will follow up after some time to determine the actual
outage reason for any outages which still have a reason of Unknown submitted.
Upcoming Model Change Outages created for the purpose of correcting system topology related to pending model changes.
This cause should only be used by SPP operations personnel.
Other Operation of facilities due to a reason not listed here.
f. Generation Outages/Derate Submission Requirements
All generating resources within the SPP Reliability Coordinator Area or Balancing Authority Area meeting one
or more of the criteria listed below (regardless of voltage connection) shall report in CROW all Outages and
Derates if the gross reduction in capability is greater than or equal to 25 MW. Changes to the reported
capability shall be reported in 25 MW increments from the last reported Derate level regardless of system
capability/conditions.
• Generating resource(s) with gross individual nameplate rating greater than 20 MVA or gross
plant/facility aggregate nameplate rating greater than 25 MVA; or
• Blackstart Resources identified in a Transmission Operator’s restoration plan; or
• Dispersed power producing resources with aggregate capacity greater than 25 MVA (gross aggregate
nameplate rating) utilizing a system designed primarily for aggregating capacity.
If SPP requires generating resources that do not meet the criteria above to report their Outages and/or
Derates in CROW, then SPP shall send a written notice to the responsible entity stating their obligations and
identifying the specific generating resources.
For the generating resources under the functional control of a Generator Operator (GOP) registered with
NERC, the GOP shall be the responsible entity for reporting Outages and Derates in CROW. For all other
generating resources not under the functional control of a registered GOP, the resource owner shall be the
responsible entity for reporting Outages and Derates in CROW.
g. Forced Generation Outages/Derate Submission Requirements
Page 7 of 25
Forced outages or capability limitations in the form of Derates should be submitted within 30 minutes or as
soon as practical after the outage or capability limitation occurs. Forced Generation Outages and Derates
are required to be accompanied by a reason for the outage or limitation. Each Outage or Derate submission
must be accompanied by a Planned End Time, a Forced Outage Priority, Outage Request Type, and an
Outage Cause. Forced Outage Priority requests will be assumed to be Non-Recallable. At the time of
submission, forced outage reasons may not be known so a reason of Unknown may be selected. The
Planned Start Time of the outage should reflect the best known time of the actual outage. The CROW tool
will ensure that the Actual Start Time and Planned Start Time are equal. Any known updates to the Planned
End Time and/or reason for the outage shall be submitted promptly to the CROW tool. This outage
submission shall be in addition to any other notifications made to SPP such as through a Reserve Sharing
event, or Resource Plan submission. SPP shall accept each forced outage within 30 minutes of submission.
h. Scheduled Generation Outages/Derate Submission Requirements
Scheduled Outages or capability limitations in the form of Derates should be submitted as soon as possible
and to the extent possible on an annual rolling basis. Planned Generation Outages are required to be
accompanied by a reason for the outage or limitation. Each Outage or Derate submission must be
accompanied by a Planned Outage Start Time and Planned End Time, an associated Outage Priority, an
associated Outage Request Type, and an Outage Cause. Each outage request must also be designated as
Non-Recallable, or provide an expected Recall time if directed. Once the actual outage takes place, the
Actual Start Time of the outage must be submitted to the CROW tool. SPP shall respond to all scheduled
outages or capacity limitation changes in the CROW system within 30 minutes from the time of submission
for changes that are effective within the next 48 hours. When the outage has ended, the Actual End Time of
the outage must be updated. This outage submission shall be in addition to any other notifications made to
SPP such as through a Reserve Sharing event or Resource Plan submission.
1. Reserve Shutdown
Resources in SPP are considered to be in a Reserve Shutdown outage status when SPP has approved an
outage request via the CROW tool, making the Resource unavailable for SPP commitment and dispatch
due to reasons other than to perform maintenance or to repair equipment. These resources will be
reflected in Planned Outage for a reason of Excess Capacity/Economic.
Resources that are offline for economic or excess capacity reasons and can be recalled, started, and
synchronized to pick up load within 7 days are not required to request an outage via the CROW tool.
Page 8 of 25
However, these Resources may request and be shown in Reserve Shutdown outage status if the outage
is approved by SPP.
i. Generation Outage/Derate Priority and Timing Requirements
Each Generation Outage or Derate submitted must include one of the following Outage Priorities. Forced
outages of equipment must be submitted with a Priority of Forced as defined below. The CROW tool will
enforce the lead time requirements of each Outage Priority.
Priority Definition Minimum Lead

cause should only be used by SPP operations personnel.
2. Outage Review / Approval Process
Page 10 of 25
All outages submitted will be studied to determine if any potential reliability conflicts are found. The general study
method employed by SPP staff involves building representative models of the study time period and implementing
all outage requests submitted for that time period. The resulting modeled system is then studied to determine if
any reliability issues can be identified. If issues are identified, various mitigation steps are then studied including but
not limited to, generation redispatch, system reconfiguration, rescheduling of lower priority outages, and facility
rating reviews. If mitigations are unsuccessful in resolving the conflict, an outage request may need to be
rescheduled or denied. Priority of outage requests is reviewed based upon initial submission time, outage priority
category, reason for the outage, and impact to reliability. To the extent possible, higher priority category requests
will be given preference, but ultimately it is up to the SPP RC to resolve any scheduling conflicts.
In the event that a conflict occurs with another Reliability Coordinator’s outage, a priority of the outages will be
determined based on submitted time, reason for outage, and impact to reliability. The determination will be
reviewed and agreed upon by each Reliability Coordinator. The outage that is deemed a higher priority will be
approved.
An outage that has been studied will receive a status change to one of the following statuses: Approved, Denied, or
Pre-Approved. Pre-Approval will be provided in certain cases where an outage has been submitted, but for various
reasons SPP is unable to adequately study the outage or determine that no reliability conflicts exist. The Pre-
Approval may also be dependent upon a specific operating condition that may need to be met but cannot be
guaranteed at the time the Pre-Approval is issued such as but not limited to a load forecast threshold, simultaneous
outage, new facilities in-service, etc. When the outage request can be adequately studied to determine that no
reliability conflict exists, the status will be changed to Approved.
All outages submitted within the appropriate advance timeframe will be reviewed as soon as possible by SPP
Operations Staff. The review timelines for SPP are as follows:
a. Transmission
1. For all BES outage requests submitted 30 days or more prior to scheduled start time, Pre-approval or
denial will be provided within 5 business days.
2. For all BES outage requests submitted 14 days or more but less than 30 days prior to the scheduled
start time, pre-approval or denial will be provided within 3 business days.
3. For all BES outage requests submitted 14 days or less prior to scheduled start time, pre-approval or
denial will be provided within 2 business days.
b. Generators
Page 11 of 25
1. For all Generator outage requests submitted 30 days or more prior to scheduled start time, Pre-
approval or denial will be provided within 5 business days.
2. For all Generator outage requests submitted 14 days or more but less than 30 days prior to the
scheduled start time, Approval, Pre-approval or denial will be provided within 3 business days.
3. For all Generator outage requests submitted 14 days or less prior to scheduled start time, Approval,
Pre-approval or denial will be provided within 2 business days.
4. SPP will provide their best effort for outages submitted within 2 business days.
3. Outage Status Changes
All outages submitted will reside in one of several status types throughout the life cycle of the outage. These status
types and their associated definition are:
Status Definition
Proposed The outage request has been saved in the CROW tool and remains under the full revision control until the outage is
entered into a Submitted state by the requestor. If the requestor does not move a proposed request to the
submitted status within 30 days of the planned start date, the outage is automatically Withdrawn. Proposed
outage request status dates DO NOT qualify for outage queuing in conflict resolution. Proposed outage requests
are not provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Submitted The outage request has been submitted into the CROW tool and is ready for review by SPP. The outage requestor
does not possess revision control of the outage in this status. A revision request may be submitted to SPP regarding
an outage in Submitted status. Outage requests in this state are provided to external systems such as NERC
SDX/IDC or SPP’s EMS.
Study SPP will change the status type to Study once the active study process begins. Outage requests in this state are
provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Preliminary
Approved
Outage requests with Preliminary Approved status have been approved based on long lead studies and may need
additional analysis closer to the planned start date or finalization of an Operating Guide. Once the restudy is
complete or final opguide posted, the outage status is changed to Approved. Outage requests in this state are
provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Approved Approved state indicates SPP has completed the study process and the outage request is ready for implementation.
Outage requests in this state are provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Implemented Once the outage request actual start time has been entered, signifying that the outage has begun, the outage
status is changed to Implemented. Outage requests in this state are provided to external systems such as NERC
SDX/IDC or SPP’s EMS.
Completed Once the outage request actual end time has been entered, signifying that the outage has ended, the outage status
is changed to Completed. Outage requests in this state are NO LONGER provided to external systems such as NERC
SDX/IDC or SPP’s EMS.
Page 12 of 25
Certain outage requests may result in a need by the outage requestor to withdraw or cancel the outage request.
SPP’s study results and coordination may also result in status changes to an outage reflecting the inability of the
outage request to be approved or implemented. These status types are:
Status Definition
Withdrawn The outage requestor can withdraw an outage request while it is still in Proposed status. Once in Study or Approved
status, the request must be Cancelled. Outage requests in this state are NOT provided to external systems such as
NERC SDX/IDC or SPP’s EMS.
Cancelled The outage requestor can cancel a Submitted or Approved outage. Cancelled outages can be reinstated by the
requestor, provided the planned start of the outage falls within the business rules for lead time submission. Outage
requests in this state are NOT provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Denied An outage request that is in Submitted or Study status can be Denied. If SPP denies the request, the status changes
to Denied. This state indicates the outage request was not approved for implementation. Outage requests in this
state are NOT provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Revoked Once an outage request has been Approved, it can be Revoked at an time (ie, before or during the outage). Outage
requests in this state are NOT provided to external systems such as NERC SDX/IDC or SPP’s EMS.
4. Using CROW to Submit Other Types of Information to SPP
CROW can be used as a mechanism to submit information to SPP other than outage and or status information on
lines, transformers, and generators. All other types of information exchange made using CROW not previously
described in this Appendix 12 will follow the guidelines below.

Appendix OP-13: Voltage Stability Assessment and Monitoring Methodology
Change History: 4/27/2017 Initial Version
Purpose
The purpose of this methodology is to provide technical requirements and criteria to Transmission Operators, Generator Operators and SPP Staff related to the voltage stability assessment and monitoring of pre- and post-contingency (single and multiple) operating conditions. Monitored scenarios will be identified using available reliability studies, real-time system information, outage schedules, and other relevant sources. During the different Operating Horizons, the pre- and post-contingency operating conditions being studied may require adjustment. The SPP RC and TOPs must determine and coordinate which Multiple Contingencies within the TOP areas are credible to be utilized for study in the operating horizon. If the TOP or the SPP RC determine that changes are required for a pre- or post-contingency operating condition, such changes shall be communicated to the affected entities. The SPP RC will coordinate with all applicable impacted TOPs or neighboring RCs. The use of proxy flowgate limits for voltage stability will be communicated in the same manner as other flowgate limits and information. 1. Study Models
1. SPP utilizes both the EMS model and the approved Planning Base Cases for establishing, calculating and monitoring SOLs/IROLs in the operating horizons. These cases are updated periodically to reflect expected system topology changes based on reported facility outages or upgrades.
2. Real Time and Post Contingent Voltage Stability Limits
1. The SPP RC will perform a voltage stability assessment for identified areas and paths that have a reasonable potential to cause real-time and post-contingency voltage instability.
2. The SPP RC may identify and establish voltage stability limits based on the voltage stability assessment results and will coordinate the voltage stability limits with the affected TOPs. Voltage stability limits may require development of new temporary flowgates.
3. Voltage stability real-time and single-contingency limits will include a 5% MW margin.
4. Voltage stability multiple-contingency limits will include a 2.5 % MW margin.
5. A voltage stability limit more restrictive than an existing SOL will be identified as the revised SOL and communicated to affected entities prior to implementation in congestion management procedures.
6. If system conditions in conjunction with real-time voltage stability assessments are determined to be stable, conditions within the 5% MW margin of the voltage stability limit than was previously defined, then the SPP RC may adjust the limit after coordinating an agreement with the affected TOPs.
7. The RC will coordinate with the impacted TOPs to establish necessary mitigations and operating plans.

SPP RC Outage Coordination Methodology (Initial Creation)
Appendix OP-2:Southwest Power Pool
Reliability Coordinator Outage Coordination Methodology Purpose
The purpose of this methodology is to provide technical requirements and criteria to Transmission Operators,
Generator Operators and SPP Staff related to submission of Transmission and Generation outages to the SPP
Reliability Coordinator and SPP Balancing Authority via the SPP CROW tool. Outage submissions will be shared
with other Reliability Coordinators, Transmission Operators, and Balancing Authorities via the NERC System
Data Exchange (SDX) and will be used for assessing real-time and future reliability of the Bulk Electric System.
Transmission and Ggeneratorion Ooperators are responsible for submitting all outages through the CROW
tool. All other Ttransmission Ooperators will be able to view and identify all outages that are submitted
through the CROW tool. SPP reserves the right to approve, deny, or reschedule any outage deemed necessary
to ensure system reliability on a case by case basis regardless of date of submission.
Use of Capitalized Terms
For the purposes of this document, the following rules should be used concerning the use of capitalized terms.
Non-italicized capitalized terms are defined by the NERC Glossary of Terms. Italicized capitalized terms
indicate terms used in the CROW tool itself. Further description of many of these italicized capitalized terms
can be found in the CROW Outage Scheduler Web GUI Tutorial.
5.1. Transmission Outages and Operations
For the purpose of identifying applicable facilities, the nominal kV level of the facility will be used. For
transformers, use the low side voltage class. Example: A 161/69kV transformer shall be classified as a
69kV facility for the purposes of this methodology.
a. Forced Transmission Outage Submission Requirements
Forced outages of all transmission facilities greater than 60kV that are modeled in the SPP regional
models and have been modeled in the CROW tool should be submitted within 30 minutes or as
Page 16 of 25
soon as practical after the outage. Each outage submission must be accompanied by a Planned End
Time, Forced Outage Priority, an associated Outage Request Type, and an Outage Cause. Forced
Outage Priory outages will be considered Non-Recallable. At the time of submission, forced outage
reasons may not be known so a reason of Unknown may be selected. It is recognized that the
duration of a forced outage will typically not be known at the time of the initial submission. The
Planned End Time should be the best estimate for the return of the outaged facility. Any known
updates to the Planned End Time and/or reason for the outage shall be submitted promptly to the
CROW tool.
b. Scheduled Transmission Outage Submission Requirements
Scheduled outages of all BES elements must be submitted to the CROW tool and approved by the
Reliability Coordinator prior to implementing the outage. Scheduled outages of all other
transmission elements greater than 60kV that are modeled in the SPP regional models must be
submitted to the Reliability Coordinator’s CROW tool for coordination and review. Each outage
submission must be accompanied by a Planned Outage Start Time and Planned End Time, Outage
Priority, Outage Request Type, and Outage Cause. Each outage request must also be designated as
Non-Recallable, or provide an expected Recall Ttime if directed. Sufficient notation in the outage
scheduler “Requestor Notes” comment field should include a description or explanation for the
outage. An incomplete outage request of any missing data could result in the outage being denied.
Once the actual outage takes place, the Actual Start Time of the outage must be submitted to the
CROW tool. When the outage has ended, the Actual End Time of the outage must be updated.
c. Transmission Outage Priority and Timing Requirements
Each Transmission Outage submitted must include one of the following Outage Priorities. Forced
Ooutages of equipment must be submitted with an Outage Priority of Forced as defined below.
The CROW Outage Schedulertool will enforce the lead time requirements of each Outage Priority.
Outages that are not planned will have a lower priority and may not be approved by the RC.
Outages not submitted as planned will be reviewed and approved by SPP on a case-by-case basis.
The risk of imminent equipment failure will have priority over other outages including planned. If
sufficient time is not available to analyze the request then the outage will be denied.

6.2. Generation Outages/Derates
a. Generation Outages/Derate Submission Requirements
All generating resources within the SPP Reliability Coordinator Area or Balancing Authority Area
meeting one or more of the criteria listed below (regardless of voltage connection) shall report in
the CROW tool all Outages and Derates if the gross reduction in capability is greater than or equal
to 25 MW. Changes to the reported capability shall be reported in 25 MW increments from the last
reported Derate level regardless of system capability/conditions.
Page 19 of 25
1. Generating resource(s) with gross individual nameplate rating greater than 20 MVA or gross
plant/facility aggregate nameplate rating greater than 25 MVA; or
2. Blackstart Resources identified in a Transmission Operator’s restoration plan; or
3. Dispersed power producing resources with aggregate capacity greater than 25 MVA (gross
aggregate nameplate rating) utilizing a system designed primarily for aggregating capacity.
If SPP requires generating resources that do not meet the criteria above to report their Outages
and/or Derates in the CROW tool, then SPP shall send a written notice to the responsible entity
stating their obligations and identifying the specific generating resources.
For the generating resources under the functional control of a Generator Operator (GOP)
registered with NERC, the GOP shall be the responsible entity for reporting Outages and Derates in
the CROW tool. For all other generating resources not under the functional control of a registered
GOP, the resource owner shall be the responsible entity for reporting Outages and Derates in the
CROW tool.
b. Forced Generation Outages/Derate Submission Requirements
Forced outages or capability limitations in the form of Derates should be submitted within 30
minutes or as soon as practical after the outage or capability limitation occurs. Forced Generation
Outages and Derates are required to be accompanied by a reason for the outage or limitation.
Each Outage or Derate submission must be accompanied by a Planned End Time, a Forced Outage
Priority, Outage Request Type, and an Outage Cause. Forced Outage Priority requests will be
assumed to be Non-Recallable. At the time of submission, forced outage reasons may not be
known so a reason of Unknown may be selected. The Planned Start Time of the outage should
reflect the best known time of the actual outage. The CROW tool will ensure that the Actual Start
Time and Planned Start Time are equal. Any known updates to the Planned End Time and/or
reason for the outage shall be submitted promptly to the CROW tool. This outage submission shall
be in addition to any other notifications made to SPP such as through a rReserve sSharing event, or
rResource pPlan submission. SPP shall accept each forced outage within 30 minutes of submission.
c. Scheduled Generation Outages/Derate Submission Requirements
Scheduled Outages or capability limitations in the form of Derates should be submitted as soon as
possible and to the extent possible on an annual rolling basis. Planned Generation Outages are
Page 20 of 25
required to be accompanied by a reason for the outage or limitation. Each Outage or Derate
submission must be accompanied by a Planned Outage Start Time and Planned End Time, an
associated Outage Priority, an associated Outage Request Type, and an Outage Cause. Each outage
request must also be designated as Non-Recallable, or provide an expected Recall Ttime if directed.
Once the actual outage takes place, the Actual Start Time of the outage must be submitted to the
CROW tool. SPP shall respond to all scheduled outages or capacity limitation changes in the CROW
system tool within 30 minutes from the time of submission for changes that are effective within the
next 48 hours. When the outage has ended, the Actual End Time of the outage must be updated.
This outage submission shall be in addition to any other notifications made to SPP such as through
a rReserve sSharing event or rResource pPlan submission.
2.1. Reserve Shutdown
Resources in SPP are considered to be in a Reserve Shutdown outage status when SPP has
approved an outage request via the CROW tool, making the rResource unavailable for SPP
commitment and dispatch due to reasons other than to perform maintenance or to repair
equipment. These resources will be reflected in Planned Outage for a reason of Excess
Capacity/Economic.
Resources that are offline for economic or excess capacity reasons and can be recalled, started,
and synchronized to pick up load within 7 days are not required to request an outage via the
CROW tool. However, these rResources may request and be shown in Reserve Shutdown
outage status if the outage is approved by SPP.
d. Generation Outage/Derate Priority and Timing Requirements
Each Generation Outage or Derate submitted must include one of the following Outage Priorities.
Forced outages of equipment must be submitted with a Priority of Forced as defined below. The
CROW tool will enforce the lead time requirements of each Outage Priority.
Priority Definition Minimum Lead
Time
Maximum Lead
Time
Planned Equipment is known to be operable with little risk of leading to a forced
outage. As required for preventive maintenance, troubleshooting, repairs
that are not viewed as urgent, system improvements such as capacity
upgrades, the installation of additional facilities, or the replacement of
equipment due to obsolescence.
14 Calendar
Days
None
Page 21 of 25
Opportunity Lead time may be very short or zero. An outage that can be taken due to
changed system conditions (ie Loading conditions allow planned work to
occur with short lead time).
None 14 Calendar
Days
Operational Equipment is removed from service for operational reasons. This could
include outages or derates due to reliability directives or other
operational concerns not necessarily related to the generating equipment
or capability, and outages entered to correct system topology in
operating models.
None None
Urgent Equipment is known to be operable, yet carries an increased risk of a
forced outage or equipment loss. The equipment remains in service until
maintenance crews are ready to perform the work.
24 Hours 48 Hours
Emergency Equipment is to be removed from service by operator as soon as possible
because of safety concerns or increased risk to grid security.
None 24 Hours
Forced Equipment is out of service at the time of the request. None 1 Hour
e. Generation Outage/Derate Request Type
Each Generation Ooutage or Derate request submitted must include one of the following Outage
Request Types. Request Type Definition Modeling Assumption
Out of Service Generator or Resource is out of service. SDX = offline
EMS = offline
Derate Generator or Resource maximum capability is lowered from
normal operation. A new maximum capability is required to be
submitted with each Outage Request Type of Derate.
SDX = online, with new lower PMAX
EMS = online, with new lower PMAX
Informational
(INF)
Used for communicating and documenting information to SPP
regarding the resource. This status is not interpreted as a loss of
capability or capacity. This status may be used to communicate
anticipated fuel delivery issues.
None – Informational Only
f. Generation Outage/Derate Request Reasons/Causes
Each Generation Outage or Derate Request must be submitted with one of the following reasons
for the outage. Reason/Cause Definition
Equipment Failure Failure in station generation, prime mover, or other equipment has occurred. Does not include failure
of GSU transformers or interconnection facilities. Does include equipment related to fuel delivery
considered a part of the resource (such as a coal mill).
Imminent Equipment Failure Expected failure in station generation, prime mover, or other equipment. Does not include failure of
GSU transformers or interconnection facilities. Does include equipment related to fuel delivery
considered a part of the resource (such as a coal mill).
BES Reliability Removal from service or limitation to preserve or correct Bulk Electric System reliability issues either
through action of a Special Protection System, runback scheme, or as mitigation of another reliability
event.
Page 22 of 25
Loss of Interconnection Failure in interconnection equipment such as GSU transformers or other interconnection facilities.
Does not include loss of synchronization due to stability or islanding type events.
BES Stability Removal from service or limitation due to Bulk Electric System stability issues. Includes loss of
synchronization due to transient stability and/or islanding issues.
Fuel Supply Removal from service or limitation due to fuel supply interruption. Does not include local equipment
failures related to fuel supply. Includes loss of gas pressure due to offsite issue, coal supply exhaustion,
lack of headwater issues for hydro, etc.
Regulatory/Safety/Environm
ental
Removal from service or limitation due to Regulatory/Safety/Environmental restrictions such as
emission limits, OSHA, NRC, or other regulatory body limitations. Includes damage caused by weather
including but not limited to lightning, flood, earthquake, etc. This may also include limitations to hydro
due to low dissolved oxygen in tailwater or to control downstream flooding.
Unknown The default Forced Outage/Derate reason will be pre-populated with Unknown at the time of
submittal. Either during the initial outage submittal or at a later time, the Unknown reason must be
changed to reflect the actual experienced issue.
Routine Generator
Maintenance
Removal from service or limitation in order to perform repair or inspection of generation equipment.
Supporting Transmission
Outage
Removal from service or limitation in order to support a scheduled transmission outage.
Excess Capacity/Economic Removal from service or limitation due to seasonal or system capacity need. This includes peaker units
not expected to be used during winter months.
Upcoming Model Change Outages created for the purpose of correcting system topology related to pending model changes. This
cause should only be used by SPP operations personnel.
7.3. Outage Review / Approval Process
All outages submitted will be studied to determine if any potential reliability conflicts are found. The
general study method employed by SPP staff involves building representative models of the study time
period and implementing all outage requests submitted for that time period. The resulting modeled
system is then studied to determine if any reliability issues can be identified. If issues are identified,
various mitigation steps are then studied including but not limited to, generation redispatch, system
reconfiguration, rescheduling of lower priority outages, and facility rating reviews. If mitigations are
unsuccessful in resolving the conflict, an outage request may need to be rescheduled or denied. Priority of
outage requests is reviewed based upon initial submission time, outage priority category, reason for the
outage, and impact to reliability. To the extent possible, higher priority category requests will be given
preference, but ultimately it is up to the SPP RC to resolve any scheduling conflicts.
In the event that a conflict occurs with another Reliability Coordinator’s outage, a priority of the outages
will be determined based on submitted time, reason for outage, and impact to reliability. The
Page 23 of 25
determination will be reviewed and agreed upon by each Reliability Coordinator. The outage that is
deemed a higher priority will be approved.
An outage that has been studied will receive a status change to one of the following statuses: Approved,
Denied, or Pre-Approved. Pre-Approval will be provided in certain cases where an outage has been
submitted, but for various reasons SPP is unable to adequately study the outage or determine that no
reliability conflicts exist. The Pre-Approval may also be dependent upon a specific operating condition that
may need to be met but cannot be guaranteed at the time the Pre-Approval is issued such as but not
limited to a load forecast threshold, simultaneous outage, new facilities in-service, etc. When the outage
request can be adequately studied to determine that no reliability conflict exists, the status will be
changed to Approved.
All outages submitted within the appropriate advance timeframe will be reviewed as soon as possible by
SPP Operations sStaff. The review timelines for SPP are as follows:
a. Transmission
1. For all BES outage requests submitted 30 days or more prior to scheduled start time,
Pre-Aapproval or Ddenial will be provided within 5 business days.
2. For all BES outage requests submitted 14 days or more but less than 30 days prior to the
scheduled start time, Ppre-Aapproval or Ddenial will be provided within 3 business days.
3. For all BES outage requests submitted 14 days or less prior to scheduled start time,
Ppre-Aapproval or Ddenial will be provided within 2 business days.
b. Generators
1. For all Generator Ooutage Rrequests submitted 30 days or more prior to scheduled start
time, Pre-Aapproval or Ddenial will be provided within 5 business days.
2. For all Generator Ooutage Rrequests submitted 14 days or more but less than 30 days
prior to the scheduled start time, Approval, Pre-Aapproval or Ddenial will be provided
within 3 business days.
3. For all Generator outage requests submitted 14 days or less prior to scheduled start
time, Approval, Pre-Aapproval or Ddenial will be provided within 2 business days.
4. SPP will provide their best effort for Ooutages Ssubmitted within 2 business days.
8.4. Outage Status Changes
Page 24 of 25
All outages submitted will reside in one of several status types throughout the life cycle of the outage.
These status types and their associated definition are: Status Definition
Proposed The outage request has been saved in the CROW tool and remains under the full revision control until the outage is
entered into a Submitted state by the requestor. If the requestor does not move a proposed request to the
submitted status within 30 days of the planned start date, the outage is automatically Withdrawn. Proposed
outage request status dates DO NOT qualify for outage queuing in conflict resolution. Proposed outage requests
are not provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Submitted The outage request has been submitted into the CROW tool and is ready for review by SPP. The outage requestor
does not possess revision control of the outage in this status. A revision request may be submitted to SPP regarding
an outage in Submitted status. Outage requests in this state are provided to external systems such as NERC
SDX/IDC or SPP’s EMS.
Study SPP will change the status type to Study once the active study process begins. Outage requests in this state are
provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Preliminary
Approved
Outage requests with Preliminary Approved status have been approved based on long lead studies and may need
additional analysis closer to the planned start date or finalization of an Operating Guide. Once the restudy is
complete or final opguide posted, the outage status is changed to Approved. Outage requests in this state are
provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Approved Approved state indicates SPP has completed the study process and the outage request is ready for implementation.
Outage requests in this state are provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Implemented Once the outage request actual start time has been entered, signifying that the outage has begun, the outage
status is changed to Implemented. Outage requests in this state are provided to external systems such as NERC
SDX/IDC or SPP’s EMS.
Completed Once the outage request actual end time has been entered, signifying that the outage has ended, the outage status
is changed to Completed. Outage requests in this state are NO LONGER provided to external systems such as NERC
SDX/IDC or SPP’s EMS.
Certain outage requests may result in a need by the outage requestor to withdraw or cancel the outage
request. SPP’s study results and coordination may also result in status changes to an outage reflecting the
inability of the Ooutage Rrequest to be Aapproved or Iimplemented. These status types are:
Status Definition
Withdrawn The outage requestor can withdraw an outage request while it is still in Proposed status. Once in Study or Approved
status, the request must be Cancelled. Outage requests in this state are NOT provided to external systems such as
NERC SDX/IDC or SPP’s EMS.
Cancelled The outage requestor can cancel a Submitted or Approved outage. Cancelled outages can be reinstated by the
requestor, provided the planned start of the outage falls within the business rules for lead time submission. Outage
requests in this state are NOT provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Denied An outage request that is in Submitted or Study status can be Denied. If SPP denies the request, the status changes
to Denied. This state indicates the outage request was not approved for implementation. Outage requests in this
state are NOT provided to external systems such as NERC SDX/IDC or SPP’s EMS.
Page 25 of 25
Revoked Once an outage request has been Approved, it can be Revoked at an time (ie, before or during the outage). Outage
requests in this state are NOT provided to external systems such as NERC SDX/IDC or SPP’s EMS.
9.5. Using CROW to Submit Other Types of Information to SPP
The CROW tool can be used as a mechanism to submit information to SPP other than outage and or status
information on lines, transformers, and generators. All other types of information exchange made using
the CROW tool not previously described in this Appendix 12 OP-2SPP RC Outage Coordination

Page 2 of 2
A need has been identified for SPP to have the option to assign an Out-of-Merit Energy (OOME) cap and/or floor, in addition to the current ability to assign a fixed dispatch MW. This change will allow Resources operating under an OOME cap and/or floor to be economically dispatched up to and including the OOME limits. Under the current method of assigning a fixed OOME MW, Resources are not able to be dispatched economically by SCED (even when being dispatched would help the situation for which an OOME has been issued). If SPP needs a positively impacting Resource to remain above a certain output, SPP currently must assign a fixed OOME MW value to keep the Resource at a specific level. This RR would allow SPP to manually set a floor for the dispatch and allow SCED to dispatch the Resource up and/or down to this OOME floor. The same would apply to a Resource negatively affecting a flowgate. SPP needs the Resource to remain below a certain value. This RR would allow SPP to manually set a cap for the dispatch and allow SCED to economically dispatch the Resource down and/or up to the OOME cap. Language is added to 4.4.2.5 to define SPP’s ability to place an OOME maximum and/or minimum MW on a Resource during an OOME event. Language is also added to 4.5.9.9 to include the OOME cap and floor in the MWP considerations for Resources that are issued an OOME.
Benefits that will be realized from this revision:
This change will allow Resources operating under an OOME cap and/or floor to be economically dispatched up to and including the newly defined OOME limits.

PROPOSED REVISION(S) TO SPP DOCUMENTS
Market Protocols
4.4.2.5 Out-of-Merit Energy (OOME) Dispatch
SPP may issue an OOME to any Resource not on outage. An OOME will specify either the a fixed MW level or an OOME cap and/or OOME floor MW level the Resource is expected to produce until such time as the issue can be resolved. When an OOME contains a fixed OOME MW, the Resource is instructed to generate equal to the specified fixed OOME MW. When an OOME contains an OOME cap MW and/or OOME floor MW, the resource is instructed to generate below the OOME cap MW and/or above the OOME floor MW respectively. Such MW levels may include (i) dispatch below a Resource’s Minimum Economic Capacity Operating Limit down to Minimum Normal Capacity Operating Limit or Minimum Emergency Capacity Operating Limit as system conditions warrant or (ii) dispatch above a Resource’s Maximum Economic Capacity Operating Limit up to Maximum Normal Capacity Operating Limit or Maximum Emergency
Capacity Operating Limit as system conditions warrant. During the period of time an OOME is imposed, the Resource will not be eligible to clear Operating Reserves. SPP will make every effort to define and activate the appropriate constraint(s). A Qualifying Facility exercising its rights under PURPA to deliver its net output to its host utility may be issued OOMEs only during an Emergency Condition or a reliability issue equivalent to a TLR 5 or greater. A local transmission operator may 1) request the Transmission Provider to issue an OOME, or 2) issue an OOME directly to the Resource(s). If the local transmission operator determines there is an adequate amount of time prior to issuing the OOME directly to the Resource, the transmission operator will coordinate with SPP to ensure the OOME is provided by SPP. If the initial OOME is issued by the local transmission operator, the local transmission operator shall coordinate with SPP to ensure subsequent OOMEs are provided by SPP. An OOME issued directly by the local transmission operator may also specify either a fixed MW level or an OOME cap and/or OOME floor MW level.
4.4.2.5.1 Fixed OOME
(1) During the period of time when a fixedan OOME is imposed, SPP will ensure that the following occurs:
(a) A notification is immediately issued containing a Dispatch Instruction equal to the fixed MW level the Resource is instructed to produce and the OOME flag is set equal to “True”;
(b) Setpoint Instructions and Economic/Emergency Minimum and Economic/Emergency Maximum Limits for the current Dispatch Interval are immediately adjusted to the fixed MW level the Resource is instructed to produce;
(i) For VERs, the Economic/Emergency Minimum and Economic/Emergency Maximum Limits for the current Dispatch Interval are immediately adjusted to the fixed MW level the Resource is instructed to produce and the Setpoint Instructions will be immediately adjusted to the lesser of the fixed MW level the Resource is instructed to produce or the echo of the actual SCADA;
(c) Setpoint Instructions for future intervals and Economic/Emergency Minimum and Economic/Emergency Maximum limits not yet dispatched will be set to the fixed MW level the resource is instructed to produce;
(i) For VERs, the Economic/Emergency Minimum and Economic/Emergency Maximum limits not yet dispatched will be set to the MW level the Resource is instructed to produce and the Setpoint Instructions will be set to the lesser
of the fixed MW level the Resource is instructed to produce or the echo of actual SCADA output; and
(d) SPP systematically notifies the Market Participant when the OOME has ended.;
4.4.2.5.2 OOME Cap and OOME Floor
(1) During the period of time when an OOME contains an OOME cap and/or OOME floor, SPP will ensure that the following occurs:
(a) A notification is immediately issued containing a Dispatch Instruction as defined in (i) to (iii) below and the OOME flag is set equal to “True”; (i) If the current Dispatch Instruction is greater than the OOME cap MW, the
Dispatch Instruction will be adjusted to the OOME cap MW; (ii) If the current Dispatch Instruction is less than the OOME floor MW, the
Dispatch Instruction will be adjusted to the OOME floor MW; (iii) If the current Dispatch Instruction is less than or equal to the OOME cap
MW and/or greater than or equal to the OOME floor MW, the Dispatch Instruction will not be adjusted;
(b) Setpoint Instructions for the current Dispatch Interval are immediately adjusted; (i) If the current Setpoint Instruction is greater than the OOME cap MW, the
Setpoint Instruction will be adjusted to the OOME cap MW; (ii) If the current Setpoint Instruction is less than the OOME floor MW, the
Setpoint Instruction will be adjusted to the OOME floor MW; (iii) If the current Setpoint Instruction is less than or equal to the OOME cap
MW and/or greater than or equal to the OOME floor MW, the Setpoint Instructions will not be adjusted;
(c) Economic/Emergency Minimum Limits for the current Dispatch Interval are immediately adjusted to the OOME floor MW. Economic/Emergency Maximum Limits for the current Dispatch Interval are immediately adjusted to the OOME cap MW;
(a)(d) For future intervals not yet dispatched the Economic/Emergency Maximum Limits will be set equal to the OOME cap MW. For future intervals not yet dispatched the Economic/Emergency Minimum Limits will be set equal to the OOME floor MW;
(e) The resource will be dispatchable in RTBM SCED; and (f) SPP systematically notifies the Market Participant when the OOME has ended;
(2) To the extent that the OOME was initiated directly by a local transmission operator, Market Participants shall be compensated for the period of time the OOME was imposed in accordance with Section 4.5.9.9 as if they had been issued an OOME by SPP; except that if the Market Monitor determines that the Resource selected pursuant to Section 4.4.2.5 was selected by the local transmission operator in a discriminatory manner and the Resource was affiliated with the local transmission operator, such Resource shall not be eligible for compensation under Section 4.5.9.9. Such determination shall be made using the same standards and procedures prescribed for Resource selection in the Intra-Day Reliability Unit Commitment process, as set forth in Section 6.1.2.1 of Attachment AE to the Tariff. Recovery of any compensation shall be collected locally as described under Section 4.5.9.9.
(3) To the extent that the OOME was initiated by SPP at the request of a local transmission operator, such Resources issued OOMEs shall be selected by SPP in a non-discriminatory manner, which will be verified by the Market Monitor through the process described under Section 6.1.2.1 of Attachment AE to the Tariff. In such event, Market Participants shall be compensated for the period of time the OOME was imposed in accordance with Section 4.5.9.9. The recovery of the compensation paid by SPP shall be collected by SPP locally as described under Section 4.5.9.9.
(4) To the extent that the OOME was initiated by SPP, such Resources issued OOMEs shall be selected by SPP in a non-discriminatory manner, which will be verified by the Market Monitor through the process described under Section 6.1.2.1 of Attachment AE to the Tariff. Recovery of compensation for Resources directly issued OOMEs by SPP that are received under Section 4.5.9.9 shall be collected regionally under Section 4.5.12.
(5) SPP, the local transmission operator, and affected Resource owners shall develop operating guides to be applied to OOMEs made to relieve known and recurring reliability issues or to relieve known and recurring Emergency Conditions. Such Resources will be compensated in the same manner as any other Resource that is issued an OOME. The recovery of the compensation paid by SPP under Section 4.5.9.9 shall be collected by SPP locally as described under Section 4.5.9.9.
4.4.2.5.1 3 Out-of-Merit Energy During Emergency Conditions
If the OOME is issued to resolve an Emergency Condition, SPP will do the following in addition to the items listed in 4.4.2.5(1):
1) Declare the Emergency Condition as soon as possible by posting it on the SPP OASIS;
2) Communicate the OOME via a phone call; and
3) Displace the OOME with a market solution as soon as possible, consistent with system safety and reliability.
4.5.9 Real-Time Balancing Market Settlement
…
(9) In addition, Resources may receive a Make Whole Payment related to an OOME as described under Section 4.5.9.9, subject to certain eligibility requirements, as follows:
(a) If the Resource is issued an fixed MW level or an OOME cap and/or OOME floor by SPP in any hour that creates Out-of-Merit Energy (OOME) MW in excess of the Resource’s Dispatch Instruction and the Resource Offer costs associated with the OOME MW are greater than the Energy revenue received for the OOME MW, the Resource will receive the difference between the Energy Offer Curve costs associated with the OOME MW and the OOME MW Energy revenue. The OOME MW is calculated as Max (0, or the difference between (i) the (lesser of actual Resource output or the Resource’s floor or fixed OOME MW) and (ii) the Resource’s Desired Dispatch);
(b) If the OOME is for Energy in the down direction and the RTBM LMP is greater than the DA Market LMP, the Asset Owner will receive a credit for the difference multiplied by the OOME MW cap or fixed. The OOME MW is calculated as Max (0, the difference between (i) the Resource’s DA Market cleared Energy MW and (ii) the (greater of actual Resource output or the Resource’s OOME cap or fixed MW)); and
(c) If during the period of time when an OOME is imposed, the RTBM cleared amount of an Operating Reserve product is less than the DA Market cleared amount of the corresponding Operating Reserve product and the RTBM MCP is greater than the DA Market MCP, the Asset Owner will receive a credit for the difference multiplied by the OOMOR MW. The OOMOR MW is calculated as Max (0, the difference between the Resource’s DA Market cleared Operating Reserve MW and the Resource’s RTBM cleared Operating Reserve MW).
Make Whole Payments associated with OOME are collected as part of revenue neutrality uplift as described under Section 4.5.12.
4.5.9.9 Real-Time Out-Of-Merit Amount
(1) An RTBM credit or charge1 will be made to each Market Participant with a Resource that passes a primary Contingency Reserve deployment test as described under Section 6.1.11.1(3)(b)(i) and/or otherwise receives an OOME from SPP or a local transmission operator that creates a cost to the Asset Owner or that adversely impacts the Asset Owner’s DA Market position and/or if a Market Participant must buy back its DA Market position for any Operating Reserve product at a RTBM MCP that is greater than that product’s DA Market MCP. Resources issued OOMEs by or at the request of a local transmission operator in order to solve a Local Emergency Condition or a Local Reliability Issue are eligible for out-of-merit credits as defined in this Section unless selection of the Resource by the local transmission operator was performed in a discriminatory manner as determined by the MMU and the Resource was an affiliated Resource; however, a manual process is employed for the calculation of the out-of-merit credits and they will appear in the Miscellaneous Amount charge type defined in Section 4.5.11. The cost allocation of out-of-merit credits associated with OOMEs issued by or at the request of a local transmission operator will be determined hourly by multiplying an Asset Owner’s RTBM actual load in the impacted Settlement Area by a rate determined by dividing the daily sum of all out-of-merit credits applicable to the impacted Settlement Area by the daily sum of all Asset Owners’ RTBM actual load in the impacted Settlement Area. A manual process is also employed for these calculations and the charges will appear in the Miscellaneous Amount charge type defined in Section 4.5.11. Out-of-merit credits associated with OOMEs issued directly by SPP to address a reliability issue other than a Local Reliability Issue will be recovered under Section 4.5.12. The amount will be calculated on a Dispatch Interval basis under the following conditions:
(a) If the OOME is for Energy in the up direction and the Energy Offer Curve cost associated with the Out-of-Merit Energy (OOME) floor or fixed MW is greater than the RTBM LMP, the Asset Owner will receive a credit equal to the difference multiplied by the OOME floor or fixed MW. The OOME MW is calculated as Max (0, or the difference between (i) (lesser of the absolute value of the actual Resource output or the Resource’s OOME floor or fixed MW) and (ii) the Resource’s Desired Dispatch);
1 Note that this charge type will almost always produce a credit. The charge is included here for the rare occasion when a charge may be produced as a result of a data error and/or a resettlement.
(b) If the OOME is for Energy in the down direction, including a Resource de-commitment or movement of a DA Market committed MCR to a configuration with a lower applicable maximum capacity operating limit and the RTBM LMP is greater than the DA Market LMP, the Asset Owner will receive a credit for the difference multiplied by the OOME MW cap or fixed. The OOME MW is calculated as Max (0, or the difference between (i) the absolute value of the Resource’s DA Market cleared Energy MW and (ii) the (greater of the absolute value of the actual Resource output or the Resource’s OOME cap or fixed MW)); and/or
(c) If an OOME for Energy or Operating Reserve, or a Resource de-commitment instruction or movement of a DA Market committed MCR to a configuration with a lower applicable maximum capacity operating limit, causes the RTBM cleared amount of an Operating Reserve product to be less than the DA Market cleared amount of the corresponding Operating Reserve product and the RTBM MCP is greater than the DA Market MCP, the Asset Owner will receive a credit for the difference multiplied by the Out-Of-Merit-Operating Reserve (OOMOR) MW. The OOMOR MW is calculated as Max (0, or the difference between the Resource’s DA Market cleared Operating Reserve MW and the Resource’s RTBM cleared Operating Reserve MW).
To the extent that additional costs are incurred as a direct result of an OOME through the compensation mechanisms described above, Market Participants may request additional compensation through submittal of actual cost documentation to SPP. SPP will review the submitted documentation and confirm that the submitted information is sufficient to document actual costs and that all or a portion of the actual costs are eligible for recovery.
The amount to each Asset Owner (AO) for each eligible Resource Settlement Location for each Dispatch Interval is calculated as follows:

SPP Tariff (OATT) Attachment AE
6.2.4 Out-of-Merit Energy Dispatch
The Transmission Provider may issue an OOME to any Resource not on outage. The
Transmission Provider will make every effort to define and activate the appropriate constraints in
RTBM SCED within one (1) hour of the time the OOME is issued.
A local transmission operator may 1) request the Transmission Provider to issue an OOME
or 2) issue an OOME directly to the Resource(s) and will notify the Transmission Provider that it
has done so. If the local transmission operator determines there is an adequate amount of time
prior to issuing the OOME directly to the Resource, the local transmission operator will coordinate
with the Transmission Provider to ensure the OOME is provided by the Transmission Provider. If
the initial OOME is issued by the local transmission operator, the local transmission operator shall
coordinate with the Transmission Provider to ensure subsequent OOMEs are provided by the
Transmission Provider.
During the period of time an OOME is imposed, the Transmission Provider will take the
following actions:
(1) The Transmission Provider will issue an OOME at either the fixed MW level or an OOME
cap and/or OOME floor MW level the Resource is expected to produce until such time as
the constraint can be resolved by SCED through the RTBM.
(2) For the current dispatch interval and all future dispatch intervals during the period of time
an OOME is imposed, a Resource will receive Setpoint Instructions that are adjusted as
specified in the Market Protocols.
(3) The Transmission Provider will notify the Market Participant when the OOME event ends.
Page 21 of 23
(4) To the extent that the OOME was is initiated directly by a local transmission operator, such
OOME may also specify either the fixed MW level or an OOME cap and/or OOME floor
MW level. Market Participants shall be compensated for such OOME in accordance with
Section 8.6.6 of this Attachment AE as if they had been issued an OOME by the
Transmission Provider; except that if the Market Monitor determines that the Resource
selected pursuant to Section 6.2.4(4) of this Attachment AE was selected by the local
transmission operator in a discriminatory manner and the Resource was affiliated with the
local transmission operator, such Resource shall not be eligible for compensation under
Section 8.6.6 of this Attachment AE. Such determination shall be made using the same
standards and procedures prescribed for Resource selection in the Intra-Day Reliability
Unit Commitment process, as set forth in Section 6.1.2.1 of this Attachment AE. The
recovery of the compensation paid by the Transmission Provider shall be collected by the
Transmission Provider locally as described under Section 8.6.7(B) of this Attachment AE.
(5) To the extent that the OOME was initiated by the Transmission Provider at the request of
a local transmission operator, such Resources issued OOMEs shall be selected by the
Transmission Provider in a non-discriminatory manner, which will be verified by the
Market Monitor through the process described under Section 6.1.2.1 of this Attachment
AE. In such event, Market Participants shall be compensated for such OOMEs in
accordance with Section 8.6.6 of this Attachment AE. The recovery of the compensation
paid by the Transmission Provider shall be collected by the Transmission Provider locally
as described under Section 8.6.7(B) of this Attachment AE.
(6) To the extent that the OOME was initiated by the Transmission Provider, such Resources
issued an OOME shall be selected by the Transmission Provider in a non-discriminatory
manner, which will be verified by the Market Monitor through the process described under
Section 6.1.2.1 of this Attachment AE. Recovery of compensation for Resources directly
issued OOMEs by Transmission Provider that are received under Section 8.6.6 of this
Attachment AE shall be collected regionally under Section 8.8 of this Attachment AE.
(7) The Transmission Provider, local transmission operator, and affected Resource owners
shall develop operating guides to be applied to OOMEs made to relieve known and
recurring reliability issues or to relieve known and recurring Emergency Conditions. Such
Resources will be compensated in the same manner as any other Resource that is issued
OOMEs. The recovery of the compensation paid by the Transmission Provider under
Page 22 of 23
Section 8.6.6 of this Attachment AE shall be collected by the Transmission Provider locally
as described under Section 8.6.7(B) of this Attachment AE.
In addition to the actions listed above, if an OOME is issued in response to an Emergency
Condition, the Transmission Provider will post the Emergency Condition on OASIS as soon as
possible. The Transmission Provider shall displace the OOME with a market solution as soon as
possible consistent with system safety and reliability.
8.6.6 Real-Time Out-of-Merit Amount
An RTBM OOME payment will be made for each Asset Owner with a Resource that passes
a primary Contingency Reserve deployment test as described in Section 2.10.1 of this Attachment
AE and/or receives an OOME from the Transmission Provider or local transmission operator that
creates a cost to the Asset Owner or that adversely impacts the Asset Owner’s Day-Ahead Market
position for Energy and/or Operating Reserve. Resources issued an OOME by the Transmission
Provider or a local transmission operator that the Market Monitor determines were selected in a
discriminatory manner, as determined pursuant to Section 6.1.2.1 of this Attachment AE, and such
Resources were affiliated with the issuing party are not eligible to receive a RTBM OOME
payment. RTBM OOME payments made to Asset Owners that received an OOME to address a
Local Reliability Issue including Local Emergency Condition shall be recovered locally as
described under Section 8.6.7(B). RTBM OOME payments made to Asset Owners that received
an OOME to address a reliability issue other than a Local Reliability Issue shall be recovered
regionally under Section 8.8. The amount will be calculated on a Dispatch Interval basis as
follows:
(1) If the OOME is for Energy in the up direction and the Energy Offer Curve cost associated
with the Resource’s additional output attributable to its response (“OOME MW”) floor or
fixed is greater than the RTBM LMP, the Asset Owner will receive a payment for the
difference multiplied by the OOME floor or fixed MW. The payment shall be limited to
the amount necessary to compensate the Asset Owner for any under-recovery resulting
from its Resource’s response to the OOME. The OOME MW is calculated as the positive
difference between (i) the lesser of the actual Resource output or the Resource’s OOME
floor or fixed MW and (ii) the Resource’s economic operating point. The Resource’s
Page 23 of 23
economic operating point is calculated as described under Section 8.6.5(4)(d) of this
Attachment AE;
(2) If the OOME is for Energy in the down direction (including a Resource de-commitment or
movement of an MCR to a configuration with a lower applicable maximum capacity
operating limit) and the RTBM LMP is greater than the Day-Ahead Market LMP, the Asset
Owner will receive a payment equal to the difference multiplied by the Resource’s
reduction in output attributable to its response (“OOME MW”) cap or fixed. The payment
shall be limited to the amount necessary to compensate the Asset Owner for any increase
in net settlement costs resulting from its response to the OOME. The OOME MW is
calculated as the maximum of zero (0) or the difference between the Resource’s Day-
Ahead Market cleared Energy MW and the greater of (i) actual Resource output or (ii) the
Resource’s OOME cap or fixed MW;
(3) If an OOME (including a Resource de-commitment instruction or movement of an MCR
to a configuration with a lower applicable maximum capacity operating limit) causes the
RTBM cleared amount of an Operating Reserve product to be less than the Day-Ahead
Market cleared amount of the corresponding Operating Reserve product and the RTBM
MCP is greater than the Day-Ahead Market MCP, the Asset Owner will receive a payment
for the difference multiplied by the OOME Operating Reserve MW. The OOME Operating
Reserve MW is calculated as the maximum of zero (0) or the difference between the
Resource’s Day-Ahead Market cleared Operating Reserve MW and the Resource’s RTBM
cleared Operating Reserve MW.
(4) To the extent that additional costs are incurred as a direct result of an OOME that are not
addressed through the compensation mechanisms described in (1) through (3) above, Asset
Owners may request additional compensation through submittal of actual cost
documentation to the Transmission Provider. The Transmission Provider will review the
submitted documentation and confirm that the submitted information is sufficient to
document actual costs and that all or a portion of the actual costs are eligible for recovery.

Objectives of Revision Request: Describe the problem/issue this revision request will resolve.
Members of the Gas-Electric Coordination Task Force have been working together with SPP to address potential issues and risks regarding uncertainty of gas procurement requirements prior to the DA Market and RUC. The Market Participants believe that having a forecasted commitment in the days prior to the DA Market will allow for them to better plan and anticipate what their fuel requirements might be without having to necessarily wait until official commitment instructions from the MDRA, DA Market and RUC.
Describe the benefits that will be realized from this revision.
This Revision Request will provide the forecasted commitment information from the Multi-Day Reliability Assessment. This information will allow Market Participants to assess their potential fuel needs ahead of time and take appropriate action if they deem necessary.
REVISIONS TO SPP DOCUMENTS In the appropriate sections below, please provide the language from the current document(s) for which you are requesting revision(s), with all edits redlined.
Market Protocols
4.2.6.3 Multi-Day Reliability Assessment Results SPP staff communicates these start-up orders to the affected Market Participants. At the time of this notification, the submitted Offers become binding and the selected Resource(s) Offers are included in the DA Market with a Commitment Status similar to Self-commit. Unlike Self-Committed Resources, however, the Multi-day Reliability Assessment committed Resources will be eligible for DA Market make-whole payment guarantees as described under Section 4.5.8.12
Each day, SPP will electronically communicate the forecasted Resource commitments out of the Multi-day Reliability Assessment. Forecasted commitments for each Market Participant will be visible only to the affected Market Participant. The forecasted commitments will be provided as part of gas-electric coordination efforts and should be considered for informational purposes only. Actual commitment instructions from SPP may differ from the forecasted commitment. SPP is not responsible for any financial implications or other impacts as the results of actions Market Participants may take based on this forecasted information. SPP will make aggregated information publically available, which will include total Resource MWH by fuel type for each interval of the Multi-day Reliability Assessment.

• Three timely doc-less interventions were filed.
Awaiting response from FERC.
Investigation Opened by FERC into SPP’s Fast Start Practices
EL18-35 FERC withdrew the pending NOPR on Fast Start pricing (RM17-3) on December 21, 2017 and opened an investigation into SPP, NYISO and PJM, separately requiring each company to respond to investigation inquiries after finding that current practices on fast start pricing may be unjust and unreasonable because those practices do not allow prices to accurately reflect the marginal cost of serving load. The investigation will examine whether SPP should revise its Tariff to, among other things: (1) modify its dispatch process to respect physical parameters of resources whole minimizing production costs; (2) modify its pricing logic to allow the commitment costs of fast-start resources to be reflected in prices; (3)
Initial Briefs by all parties are due on February 12, 2018.
Regulatory Report to MWG for February 2018 allow all quick-start resources, including block-loaded quick-start resources to set price. This investigation was set up as a “paper hearing” and such any party desiring to participate in the proceeding must file a motion to intervene. The Commission expects to issue a final order in this proceeding by September 30, 2018.
• 47 (including SPP) doc-less interventions were filed.
• Initial Briefs are due on February 12, 2018 and response briefs 30 days later.
RR 229 – Order No. 831 (Offer Cap) Compliance
ER17-1568 Filing made in compliance with Order No. 831 – Offer Caps on May 8, 2017 as directed by FERC in the Order. Comments due on May 30, 2017. Amended filing made by SPP on May 18, 2017. Comments to that filing due on June 8, 2017.

Topics• Define Reference Bus
• Give examples of necessary market calculations which use the Reference Bus
• Show problems with a single Reference Bus
• Demonstrate SPP’s load Reference Bus
• Explain Reference Bus design for MWTG project
• Show why 1 reference bus for each interconnect must be used
• Answer frequently asked questions related to this subject

What is a reference bus?• Sinking point for network calculations such as the
loss-sensitivity & shift-factor

D
Single Reference Bus Issues• What happens if D is islanded?
The powerflow equations cannot be solved with D as reference due to what is called a singular matrix error
Must switch to new reference bus (Ex: C)
• What is the impact from switching to ref bus C? Sensitivities (Ex: Shift factors) are all done with respect to new
reference, so all values change between runs, causing possible confusion with results even though they are still valid
7
C
Inject 1 MW @ a node on the system
Withdraw 1 MW @ reference bus & observe system changesD
Pricing Note• It should be noted that the LMP at each pnode is the
same regardless of which Reference Bus is chosen This is true as long as there is no change to the system state
(different topology due to an outage, flows…etc) This is true because regardless of which reference is chosen,
calculating LMP at a pnode will involve moving the same units (Ex: Unit A goes up 2 MW & Unit B goes down 1 MW)
• The components of LMP (MEC, MLC, & MCC) change along with a reference bus switch, but not the actual LMP itself
• Therefore, the common perception that the reference bus is the best location to be on the network is inaccurate with respect to LMP

• Moving from Reference bus D to Reference bus E has no impact on final LMP values
• Shift Factors and Loss Sensitivities do change
• LMP components (MEC, MLC, MCC) do change
What happens if we switch from Reference D to E with no other changes to the system?
SPP’s Reference Bus• SPP uses a reference bus composed of the market’s internal load
which always exists and changes gradually over time
• This is a fair and consistent approach as islanded equipment (Ex: switching reference bus due to bus outage) has negligible impact on sensitivities
• Below, each green pnode has a load and is thus part of the “distributed load reference” and withdraws a part of the 1 MW injection
10
C
Inject 1 MW @ a node on the system
Withdraw 1 MW @ distributed load reference bus & observe system changes
MWTG Design Continued• DC ties are controllable devices that essentially separate
the interconnects An injection in an interconnect has no AC sensitivity impact on
losses or congestion in the other interconnect Therefore, Shift factors in the East are 0% with respect to
congestion in the West and vice-versa If you imagine a 1 MW injection in either interconnect, the ties
will still remain at their set-point after the injection, so this makes logical sense
• Two reference buses must be used A distributed load reference in the East, and a distributed load
reference in the West This merely extends what we currently do today into the west Has the least impact on SPP’s internal systems

Single Reference Theoretical Design Option #1

Sensitivity Calculation

Market Clearing Engine
Shift factors and loss sensitivities
Iterate until convergence reached
• Initial Sensitivities are fed into MCE• MCE rotates sensitivities to where part of the injection in the East (Ex: 70%)
stays in the East and the other 30% goes on the DC ties based on load• The problem is determining which part of that 30% gets on what tie• MCE makes a guess and puts it on one tie and sees what happens, if the
solver wants to put it on other ties, it knows those have a higher sensitivity• Keeps solving until changes reach a minimum
Single Reference Theoretical Design Option #2
17
Sensitivity Calculation
Engine
Market Clearing Engine
Shift factors and loss sensitivities
DC tie optimal dispatch
• Shift factors and loss sensitivities from the Sensitivity Calculation Engine are fed into MCE• MCE determines optimal tie dispatch (how much flow on each tie) and feeds this back into
the Sensitivity Calculation Engine• Sensitivities are recalculated a second time (based on new info) and fed back into MCE• MCE solves again (with new sensitivities) and feeds tie dispatch back into sensitivity engine• This process continues until a certain convergence threshold is reached
• Iterates until the change in the DC tie dispatch b/t intervals gets below a certain value• Current Sensitivity Engine calculates based on impedance (common to all power systems
software for this problem) and would have to be rewritten to deal with flows!
Iterate until convergence reached
Why can’t we use a single reference?• The AC powerflow problem & sensitivity analysis is done on an island basis and each
interconnect is essentially its own island requiring its own set of equations and solution
• Historical shift factors in the East would change in perhaps a large & unforeseen way if we attempted to use a single reference
• Major changes to: Network Sensitivity Calculation engine
Market Clearing Engine (MCE)
Market Controller
Settlements
• A shift away from the sensitivity calculations used in the standard market design used by other RTO/ISO’s
• In case of an outage across all 4 ties, we would then need to revert to using 2 references This would mean a massive amount of systems duplication as we would have to switch to
a very different system when that event occurs
All sensitivities would look very different before/after the outage
Similar to hitting DC tie capacity and/or ramp limits
• Implementation could introduce iteration into a system in order to determine the incremental response of each tie that doesn’t currently use this method Possible performance and convergence impacts 18
Single Reference (Summary)
• Using a single reference instead of one in each interconnect might be possible, but it would be a long-term R&D effort to find a solution A finalized method isn’t currently available
• Implementing the changes to the market clearing engine, sensitivity engines, and settlements would be very costly
• This would entail roughly 2x the effort and ~10x the risk
19
Other general MWTG design questions• Why does SPP use two SCUCs instead of one SCUC?
One SCUC isn’t something that is currently feasible due to performance with the size of a dual MWTG/SPP model under the current DA timeline
The plan is to use one SCUC for each interconnect and to run 1 single co-optimized SCED on top of it
SPP is open to moving to 1 SCUC in the future if hardware & software advances permit it (if it becomes a robust and viable option)
• Wouldn’t one SCUC be more efficient than two SCUCs?Aren’t you missing some opportunity where an interconnect might have a less efficient unit committed that wasn’t seen by a single SCUC The theoretical missed portion would be tiny (< 1% of peak
generation) This is very similar to the distant past in our market where we
had other congestion related bottlenecks, yet it was still one single market 20
• If the market has 2 different SCUCs, 1 SCED, and 2 different reference buses, is it really a single co-optimized market Yes, the 2 different SCUCs has little impact and is due to the
unique nature of the DA problem in that it is so large and has such a small amount of time to be solved that breaking it into 2 pieces is necessary for now
The 2 different reference buses is expected for an efficient market spanning two interconnects with multiple DC ties
The single SCED has a single objective function which is to minimize the cost of the market (both interconnects together) while optimizing energy and reserves in each interconnect and finding the optimal amount & direction of DC tie dispatch

Additional Comments
I enjoyed the new meeting space. Although I couldn't hear some from the other side of the room when they were speaking and suggest getting microphones for use in the room.
Enjoyed the new conference room. The Dialog on all subjects was very good and interesting. I always learn from others so enjoy the discussions
Several meeting material updates, including during the meeting. New meeting location is better, but sound in the room may be an issue.?
Jim Flucke did an excellent job as chair of the meeting but because of his tremendous work load he should only be asked to occasionally fill in for Richard.

07/25/16 Recommendation from the 2015 ASOM Report (NDVER to DVER Conversion). MOPC AI # 272
8/14/2017: During the September MWG, staff will provide an update on all potential NDVER to DVER conversion options including the pros and cons of each with the expectation that the MWG will chose an option for SPP to further develop with the group. 9/1/2017: More discussion is planned for the NDVER to DVER conversion topic at future MWG meetings, and this discussion may be decoupled from the VER repowering discussion. 9/20/2017: SPP staff will provide an update during the October MWG meeting. 10/16/2017: SPP staff will bring a draft RR NDVER to DVER to the October MWG meeting. 10/24/2017: NDVER to DVER discussion deferred to the November 3rd MWG conference call. 11/3/2017: Deferred to January 8 MWG meeting1/8/2018: The group discussed two options; 1) RR263 NDVER to DVER Conversion through Incentives and 2) RR272 NDVER to DVER Conversion. MWG plans to take action on this topic during the February 6th meeting.2/15/2018: The MWG approved RR272 (NDVER to DVER Conversion) during the February 6th MWG meeting.

In Progress Debbie James Today at the Strategic Planning Committee the MWG was tasked to look further into the issues & a potential solution related to infeasible Auction Revenue Rights/Transmission Congestion Rights. As I suspect you are aware some parties have highlighted situations where they have secured long term firm transmission service which, in the past, facilitated/hedge the deliveries of power & energy from congestion on the system. However, today many of those parties find themselves securing & paying for transmission services, but having no hedge against the congestion cost on the system.
MWG was given the task; BUT it will require contributions from the expertise in planning from the Transmission Working Group. I’d like you to consider how we might best facilitate the engagement of the TWG or representatives from the TWG in these discussions.
Although there are many options and I will continue to consider the issue; an option would be to devote a specific period of time on the MWG meeting for this discussion and/or schedule time the day prior to the current MWG meetings. My objective being to focus the discussion so that TWG representatives could more easily attend the discussion in person without being burdened by a full day of MWG fun. I’m just throwing that out on the table & by the end of the day I may not even like it myself….ARR/TCR Firm – Inability to Hedge as Expected – While SPP is operating today per its Rules; the issue is one of Deliverability resulting from the Generation Interconnection process.
The SPC recommended that the MWG/MOPC consider if there is a better mechanism. Paul Malone on behalf of the MOPC and Richard Ross on behalf of the MWG agreed to take up the issue. Related to this issue are two others: Market Design Incentives and Market Implications Costing Cons mers326 MWG 07/18/17 SPP staff to determine if negative price signals are indicative of a
