During the address, Shri S. P. Chaturvedi, Managing Director, CSPGCL stated that the State of Chhattisgarh State has historical relevance and is famous for its traditional culture. The State is known as 'Dhan Ka Katora' being blessed with highly fertile land. It also has abundant natural resources, which are helping in development of Power, Cement and Steel industry on large scale in the State. He added that after the formation of Chhattisgarh State Electricity Board (CSEB) w.e.f. 1.11.2000, Chhattisgarh State has developed in terms of quantum of power generation capacity with participation from NTPC Ltd., BSP, BALCO & other IPPs. He further stated that though some of the operating thermal power plants in Chhattisgarh State are old, an overall increase of PLF in the State has been achieved from 65 % to 86 % during their operation period since the formation of CSEB. Chhattisgarh State has also been implementing zero power cut continuously for past 21 months, which is an added achievement. Shri Aman Singh, Special Secretary (Power) during his address stated that Chhattisgarh State is emerging as power hub of the country and it has tremendous responsibility on its shoulders to arrange coal/fuel linkages for the upcoming thermal power projects in the State for capacity addition programme of 48000 MW, for which the MOUs have already been signed with the power developers. The issues relating to redressal of R&R problems, land acquisition and arranging environmental clearances will be addressed appropriately under the leadership and guidance of the Hon'ble Chief Minister himself who also holds charge of State Urja Minister. Shri S. Jagadeesan, Chairman, WRPC and Chairman, GSECL welcomed Hon’ble Chief Minister, Dr. Raman Singh, Shri Aman Singh, Special Secretary (Power), Shri P. Joy Ommen, Secretary (Power) & Chairman, Chhattisgarh Power Companies, all members, special invitees and participants attending the meeting of WR Power Committee. He specially thanked Dr. Raman Singh, Hon'ble Chief Minister, Chhattisgarh State for sparing his valuable time from most busy schedule during visit of Shri P. Chidambaram, Hon’ble Home Minister to BALCO plant due to very sad incidence of Chimney collapse at BALCO and to attend law & order problem. He

narrated about his close association with him in the past at the Centre, when Dr. Raman Singh was Minister of State for Commerce and Industry and about keen interest taken by him in promoting Power Sector development in the State. He further stated that Chhattisgarh State is one of the backward states but in the contrary is blessed with huge natural resources. The reason behind the growth of Chhattisgarh state is the best utilization of GoI schemes from time to time under his guidance. During his address he intimated that Western Region is the largest region in country in terms of Installed capacity and power consumption. During the period June 2009 to August 2009, Regional Grid operated at system frequency within IEGC range of 49.2 Hz to 50.3 Hz on the average for about 83% of the time. However on account of prolonged dry spell, despite efforts to maximize availability in August 2009 from 17000 MUs to 19200 MUs, the highest regional peak shortfall of 6950 MW i.e. 19% and the energy shortfall of 12% had resulted in the Western Region. The situation had been getting aggravated on account of drawls from this region by other regions, above the schedules at low frequency. The unrestricted demand of the region varied from 32,450 MW to 37,050 MW against 33360 MW to 35500 during last year. Western Region continues to experience huge demand-supply gap and the same is likely to aggravate further in the coming months. The peak deficit is estimated to be around 13 to 19 %. It is expected that additional capacity of nearly 35000 MW to be added in the next 5 – 6 years by number of IPPs out of which 19350 MW capacity is to come up in the Western Region. Against 19350 MW capacity in the western region, already open access for 17300 MW is under process of approval. Therefore it becomes imperative that the evacuation system need to be completed as per the plan keeping pace with the commissioning of the generating capacities. In this context, the role of the Chhattisgarh State is of paramount importance in terms of facilitating the continued coal supply, early completion of generating units, implementation of the associated evacuation system. He hoped that the deliberations in this meeting would be fruitful for all the stakeholders and the discussions would take place in the context of facilitating quality power supply to the participant States/ utilities. He thanked the Chhattisgarh State Government and the power utilities of the State for hosting this meeting and making excellent arrangements for the same. Dr. Raman Singh, Hon'ble Chief Minister, Chhattisgarh State during his address stated that during this holy period of NAVRATRI every body is worshipping Maa Shakti (Maa DURGA) and URJA (Power) is one form of Maa Shakti. He further stated that in coming 5 years around 15000 MW power is going to be added in the state and Rs 15000 Cr. would also be required for transmission schemes for evacuation as well as strengthening for transfer of this additional power. He said that with the huge generation capacity which is expected to come up in the in near future, there would be consequential development in other Sectors too in the State. The steps are therefore on way to arrange necessary infrastructure for the same. He stated that we should plan generation and transmission both for much longer period such as upto 2015-20. He stated that coal/fuel for future can be tied up and imported from other countries as cost difference in indigenous and imported coal would be very less in future as the coal linkage for long-term generation projects would need to be supplemented from the imported coal.

Shri V. K. Verma, Managing Director, CSPHCL specially thanked the Hon'ble Chief Minister, Chhattisgarh State for sparing time out of his busy schedule to address this forum and giving his valuable guidance. He thanked Shri S. Jagadeesan, Chairman, WRPC and Chairman, GSECL, all Senior officials from the Western Regional States, CEA and all other WR Power Committee members for sparing time to attend the meeting and deliberate on issues slated for the discussion. Shri S. Jagadeesan, Chairman, WRPC and Chairman, GSECL, thereafter requested Member Secretary, WRPC to take up agenda items for the meeting. ITEM No.1: CONFIRMATION OF THE MINUTES OF THE 10th MEETING OF WRP

COMMITTEE 1.1 Member Secretary, WRPC stated that the minutes of 10th meeting of WR Power Committee held on 30th May 2009 at Diu were sent to the members vide letter No. WRPC/Minutes/AS/2009/6239 dated 15th June 2009. He stated that comments have been received from GM (Comml.), NTPC on Item No. 4, “transmission system connected with Vindhyachal pooling station and phasing of transmission work” requesting amendment in Para 4.3 and Para 4.4 of the minutes of the meeting as give below:

ITEM No.2: PERFORMANCE OF WR GRID DURING JUNE 09 TO AUG. 09 2.1 System Performance Member Secretary, WRPC stated that during the period June 2009 to August 2009, the grid operated in the frequency range of 49.2 Hz to 50.3 Hz for 83 % of time. The percentage time when frequency was within this range varied between 73.98 % to 94.74%. During this period, frequency remained below 49.2 Hz for 16.59 % of time. The frequency profile during the period was not much satisfactory except in July, 2009. During the period there was generally overdrawal by NR and ER due to prolonged dry spell/ generating unit outages. An improved system performance during the period was attributed to the synchronization of new generating units at Sugen, NSPCL-Bhilai, LANCO and APL. The details of frequency profile during the period from June 2009 to August 2009 are furnished at Annexure 2.1(a).

He said that the unrestricted demand of Western Region during the period varied between 32500 MW to 37100 MW. The corresponding figures for the previous year were between 33360 MW to 35500 MW. The maximum demand met during the period was 30115 MW and the region faced capacity shortage in the range of 4800 MW to 7000 MW. The details of Unrestricted Demand vs. Demand Met and Energy Requirement vs. Availability are furnished at Annexure-2.1(b).

Member Secretary, WRPC stated that during TCC meeting held on 24th September 2009, Gujarat, MP, Chhattisgarh and Maharashtra had suggested that planned outages of 500 MW units should not be taken in the months of October to March of the year and for the current year. It was also suggested that NTPC may plan outage of 500 MW units only after Diwali period and that the simultaneous outage of two 500 MW units of NTPC in the month of February 2010 viz KSTPS#4 from 03.02.10 to 27.02.10 and VSTPS#9 from 09.02.10 to 10.03.10 may be rescheduled. In this context, NTPC had intimated that they may not be availing simultaneous outage of two 500 MW units of NTPC in the month of February 2010 and for taking planned outage only after Diwali period they would revert back. The Committee noted the same. 2.2.1 The month-wise detail of voltages at 400 kV and 765 kV sub-stations during the month of June 2009 to August 2009 is placed at Annexure- 2.2. During the period low voltage was observed at Jetpur 400 kV touching to 352 kV on 27.08.2009 & 376 kV on 18.07.2009 and at Gwalior 400 kV touching to 365 kV on 20.07.2009, 372 kV on 13.08.2009 and 375kV on 27.06.2009. High voltage was recorded at 400 kV throughout the period at Dhule and Karad S/s in the order of 426 kV to 440 kV. To contain high voltages WRLDC had to resort to opening of 5 to 6 lines on many days. In order to control incidences of high voltages during low load periods, installation of reactors at following locations has been planned by various utilities:-

Agency Expected date of Commissioning

1. Khandwa 1x125 PGCIL June 2010 2 Dhule 2x50 MSETCL Dec. 2009 3. Dehgam 1x125 PGCIL June 2010 4. Kasor 1x125 GETCO Feb. 2010 5 Karad 1x80 MSETCL Oct. 2009 6 Nardipur( Soja) 1x80 GETCO Feb. 2010

The progress achieved on above and expected date of installation and commissioning of reactors at the above locations as above was confirmed by the concerned utilities. The implementing utilities were requested that timely commissioning of these reactors may be ensured, as this would help in smoothening of high voltage profile in Western Regional Grid. 2.2.2 The issue regarding high voltage in Dhule area was also discussed in the meeting. It was pointed out that even after taking all other actions, including opening of number of lines, high voltage problem was still persisting. PGCIL was therefore, requested to conduct fresh studies for installation of reactors at Nagda or Rajgarh. PGCIL intimated that according to studies carried by them, installation of 1X125 MVAR bus reactor at Rajgarh would be beneficial to control over voltages. Member Secretary, WRPC stated that during TCC meeting POWERGRID intimated that installation and commissioning of 1X125 MVAR bus reactor at Rajgarh sub-station would take two years of time i.e. the reactor would be commissioned by September 2011.

The Committee noted the same.

2.3 Operational Discipline

Member Secretary, WRPC stated that there had been occasions of overdrawal by NR and ER from the WR grid under low frequency regime during the period June 2009 to August 2009. Over drawl by NR grid was to the extent of 1041 MW and that by ER grid to the extent of 876 MW during the month of August 2009. The large quantum of overdrawal had been resulting in low system frequency of the interconnected grid and operation of relays under AUFLS in Western Region. The overdrawal by NR and ER had been cause of concern during the month. The subject matter of overdrawal by neighboring region from WR had been taken up by WRPC with WRLDC and NLDC. WRLDC had intimated that they had been taking up the subject matter of overdrawal by NR and ER systems from WR grid in the real-time operation at number of occasions and it further intimated that NRLDC had filed two petitions with Hon'ble CERC on 09.07.2009 and 07.08.2009 against NR constituents on the same subject. He said that overdrawal during low frequency regime from WR grid by the neighboring regions was attributing largely in causing the system frequency below 49.2 Hz thereby forcing commercial deterrent to the constituents of Western Region who were either under drawing or limitedly/marginally over drawing. It is therefore


5

essential that such instances of over drawal by the neighboring regional grids from the WR grid of N-E-W grid are contained in the interest of secured operation of the grid. Member Secretary, WRPC stated that TCC deliberated the issue and suggested that CEA may a convene joint meeting between WRLDC, NRLDC, NLDC, NRPC, WRPC, NR and WR constituents and CEA in Mumbai to resolve the issue and also in view of the ensuing Rabi peak demand period when high shortage conditions would yet continue to prevail/ aggravate. Further an effective administrative mechanism to control flows on major inter-regional links in the real time does not seem to exist at present. TCC suggested that CEA may be requested to address the issue concerning this aspect at an appropriate level and so as to have suitable remedial provisions for the same. CMD, MPPTCL stated that NR grid had been consistently overdrawing power from the grid. Also due to heavy overdrawal by NR, 220 kV Ujjain - Kota line and 220 kV Ujjain - Badod section of 220 kV Ujjain-Kota line which were synchronized with NR grid are getting over loaded. He said that this is a matter of serious concern and necessary corrective action has to be taken by NR to control the loading. He further suggested that information about performance of AUFLS in ER / NR systems and load relief obtained through the AUFLS operation should also be available to WR Constituents in similar manner as is being done by WR constituents.

Member (Power System), CEA stated that it is prudent for any overdrawing utility(ies) to restrict drawl at low frequency by effecting adequate load shedding. He added that matter regarding overdrawl by NR constituents from the grid has also been addressed by the Hon'ble CERC and penalty was also imposed on the defaulting constituent. He however suggested that to contain overloading of the interconnected link on account of overdrawl of NR the appropriate corrective action needs to be initiated by NRLDC. Director (O), MSETCL stated that Maharashtra Government has brought to the notice of Central Government the subject matter of overdrawal by other utilities from the interconnected grid, which is causing undue AUFLS operations in Maharashtra grid at low frequency, even though the State has been underdrawing after implementing large quantum of load shedding. During WRPC meeting, Chairman, WRPC suggested that subject matter of over drawal by neighboring region may be brought to the notice of CEA/Ministry of Power so that matter is taken up with Chairman, NRPC / concerned State authority. He also suggested that a joint meeting of WR/NR may also be arranged to be convened to address the issue. He said that he would also personally appraise Secretary (Power), Ministry of Power about the matter during a meeting in the coming week. After detailed discussion it was agreed that CEA would be requested to convene a joint meeting between WRLDC, NRLDC, NLDC, NRPC, WRPC, NR and WR constituents and CEA preferably at Delhi to discuss the issue and evolve a solution.

2.4 AUFLS Performance in WR

The month-wise details relating to performance of AUFLS scheme in Western Region during the period June 2009 to August 2009 in terms of quantum of load relief obtained and number of occasions the UFR operated was noted by the Committee. The detail is at Annexure-2.4.

Member Secretary, WRPC stated that the AUFLS scheme, which is operational in Western Region, is essentially a defense mechanism for safeguarding the secured operation of the interconnected grid in the event of occurrence of any type of grid disturbance. It is therefore, requested that the WR beneficiaries may ensure to always keep the above scheme in operational readiness.

The Committee noted the same. ITEM No.3: TRANSMISSION SYSTEM ASSOCIATED WITH IPPS LOCATED IN

3.1.2 In this meeting, Member (Power System), CEA stated that based on the review of progress of various IPPs in Chhattisgarh a list of 12 nos IPPS in Chhattisgarh who had made some progress which were likely to materialize during 11th plan / early 12th plan programme for which was drawn. The total installed capacity of these twelve (12) nos IPPs is 15485 MW out of which 7 no. IPPs with capacity 8540 MW are located near Raigarh complex and 5 no. IPPs with capacity 6945 MW are located near Jhangir-Champa complex. The target beneficiaries as indicated by these IPPs are 11143 MW to WR and 3742 MW to NR. For Orissa IPPs based on review with the project developers, OPTCL, CEA and POWERGRID had assessed and drawn a list of seven (7) projects with total capacity 10,090 MW which are likely to materialize by end of 11th Plan/ early 12th plan. The target beneficiaries indicated by these IPPs is 2340 MW to WR and 3315 MW to NR and balance to ER/SR. For Jharkhand and West Bengal (WBSEDCL) generation projects based on review the total installed capacity works to about 5465 MW. The target beneficiaries indicated by these IPPs is 1470 MW for WR and 2964 MW for NR and balance to ER. For IPP projects of Madhya Pradesh and Chhattisgarh (connected to Bilaspur pooling station) the total installed capacity is 3870 MW and the target beneficiaries indicated by these IPPs was 2375 MW for WR and 1095 for NR. Thus the total capacity of IPP projects in Chhatisgarh, Madhya Pradesh, Orissa, Jharkhand and West Bengal for which transmission system was considered during the 29th SCM of WR was of the order of 35,000 MW. Details of the projects is at Annex-3.1.2 He further stated that the transmission system associated with the various IPP projects located in different states was discussed during the 29th meeting of the Standing Committee on Power System Planning and the transmission system was evolved. Details of the evolved transmission are:

i) For evacuating power from 12 no. of IPPs projects in Chattishgarh it was agreed to pool power at 3 nos 765/400 kV pooling stations at Raigarh (Kotra), Raigarh (Tanmar) and Champa. Two pooling stations Raigarh (Kotra) and Raigarh (Tanmar) pooling stations have been have been planned and interconnected to reduce the ROW requirements as there is difficulty in laying lines for projects located northern part of Raigarh . At present only Jindal Power project is connected to Raigarh (Tanmar). It is understood that Jindal Power is yet to get coal linkage. Therefore the implementation of Raigarh(Tanmar) pooling station should be linked with the progress of works at Jindal power. These three pooling stations would be interconnected through Raigarh (Kotra)- Champa 765 kV S/C and Raigarh (Kotra)- Raigarh(Tamnar) 765 kV D/C line. For onward transfer of power it was agreed to further pool power at another intermediate Raipur pooling station. Raigarh Pooling station (Kotra) would be connected to Raipur pooling station through 765 kV D/C line. Similarly Champa would be connected to Raipur through 765 kV D/C lines. To provide an alternate path Champa pooling station would also be connected to Dharamjaygarh where power from other IPP projects in Orrisa, Jharkhand and W.Bengal would also be injected. For transfer of power beyond Raipur within WR, Raipur-Wardha- Aurangabad 765 kV 2xD/c lines were agreed to. Beyond Aurangabad power is proposed to be transferred through 765 kV Aurangabad-Padghe 765 kV D/C and Aurangabad- Dhule-Vadodra 765 kV S/C. For further dispersal of power at 400 kV, Aurangabad-Khargar 400 kV D/C (quad), Vadodra-Asoj 400 kV D/C


8

(quad), Dhule – Nasik 400 kV D/C (quad), Dhule – Malegaon 400 kV D/C (quad) were proposed. Also interconnection at 400 kV between the proposed 765 kV substations at Dhule, Padghe, Vadodara, Raipur pooling stations, Raigarh (Kotra) Pooling Stations to the existing substations was agreed. Also for bulk transfer of power from eastern part of Western Region to western part of Western Region a + 600 kV, 4000 MW HVDC bipole between Raigarh pooling station (Kotra) to Dhule was agreed and for bulk transfer of power to NR + 800 kV, 6000 MW HVDC bipole between Champa pooling station and around Kurushetra in Haryana was agreed with 3000 MW, 800 kV HVDC terminals at Champa and Kurushetra with provision to upgrade the terminals to 6000 MW.

ii) For evacuation of power from IPP projects in Orissa it was agreed to pool power from various IPPs located in Orissa at three number 765/400 kV pooling stations at Jharsuguda, Dhenkanal and Angul. The proposed pooling stations would be interconnected through 765 kV 2xS/C ring network and for onward transfer of power to NR and WR it was proposed to inject power at new pooling station at Dharamjaygarh in Chhattisgarh through Jharsuguda pooling- Dharamjaygarh 765 kV 2x D/c lines. In the phased development of transmission pooling stations at Jharsuguda and Angul were agreed to be set up with the initial set of 7 no IPPs likely to materialise in Orissa, which are located near to these two pooling stations. These two pooling stations are initially proposed to be interconnected through 765 kV, 2x S/C line. For evacuation of power 2 no. 765 kV D/C lines from Jharsuguda to Dharamjaygarh were agreed, one D/C line is proposed to be associated with Orrisa IPP projects who have sought open access for transfer to WR/NR and the 2nd D/C line is proposed with IPP projects in SR who have sought open access for selling power to NR/WR. From Dhramjaygarh power will be transferred to Jabalpur pooling station through 765 kV 2xD/C lines. Of the two D/c lines one D/C is associated with Orrissa IPPs and the 2nd D/C line is proposed part of transmission system associated with Jharkhand IPPs and West Bengal projects who have sought open access for transfer of power to NR/WR. From Jabalpur pooling station power would be transferred to NR through the Jabalpur-Bina- Gwalior- Jaipur- Bhiwani 765 kV line. For transfer within WR Jabalpur-Bhopal-Indore- Vadodra 765 kV 1x S/C lines were agreed. The 765 kV Jabalpur-Bhopal-Indore section of line is covered with Orissa IPPs and 765 kV Indore-Vadodra section and Vadodra- Pirana 400 kV quad is covered with Madhya Pardesh generation projects and Chhattisgarh generation projects (pooled at Bilaspur). For IPP projects in Jharkhand and West Bengal in addition to the existing Ranchi-Sipat 400 kV and Ranchi-Sipat 765 kV S/c under construction a 765 kV Ranchi- Dharamjaygarh S/C line and a 765 kV Dharamjaygarh-Jabalpur 765 kV D/C line was agreed for transfer of power to NR/WR. For MP IPPs and Chhattisgarh IPPs (pooled at Bilaspur pooling station), Indore-Vadodra 765 kV S/C and Vadodra –Pirana 400 kV D/C quad lines were agreed to.

Accordingly, the transmission system evolved and agreed in the 29th SCM of WR held at Ahmedabad on 10th Sept 2009 associated with various IPP projects is as under:

Member (PS), CEA stated that the above transmission system is to be built in phases depending upon the progress of various IPPs. The interim arrangement of providing of LILOs of the existing lines is a temporary transmission arrangement for power transfer on short term basis. The corresponding LILO shall be removed and the line shall be restored to its original configuration by the respective developer, after interconnection of the generation project at the identified Pooling Station. He further stated that till the generators identify the beneficiaries; the risk of payment of transmission charges will be borne by the generators for which they will have to open LC. He further stated that there were certain modifications with respect to the network earlier evolved and the modifications mainly were 765 kV 2xD/c lines instead of 400 kV links upgradable to 1200 kV in future between Raipur- Wardha-Aurangabad interlinking of Champa pooling station in Chhattisgarh with Dharamjaygarh instead of Bilaspur pooling Station. In regards to the query regarding the change in earlier proposal of ±600 kV, 4000 MW HVDC from Raigarh to Vadodara to now from Raigarh to Dhule, Member (PS), CEA stated that based on the discussions and inter action with GETCO, it is understood that Gujarat had signed MOU with number of IPPs for setting up of generation projects in the State and accordingly the same was reviewed and therefore is now proposed at Dhule which is a major load centre. In regard to proposal connectivity with 400 kV D/c line to Kharghar, Member (PS) requested MSETCL to expedite to intimate change/ modification if any at the earliest. He requested the WRP Committee to concur the schemes as proposed associated with various IPPs listed under A, B, C & D. Chairman, WRPC/GSECL while stressing for a broader approach in the interest of building up of strong National grid network said that minor modifications may become necessary in the proposed transmission schemes under the finalization stages while carrying out finer adjustments so as to evolve optimum system without constraints. He therefore, requested to ensure that the transmission schemes are in place for power evacuation of various upcoming IPPs. The matter was discussed and WR Power Committee gave the concurrence for implementation of the above proposed transmission schemes accordingly.

3.4 Connectivity of proposed 220/132 kV substations at Raigarh and Kumhari of Indian Rlys with existing Raigarh S/s of PGCIL for wheeling of power from Nabinagar generation project in ER to their traction substation in Chhatisgarh

GUVNL representative raised the issue concerning granting connectivity of proposed 220/132 kV substations at Raigarh and Kumhari of Indian Railways with existing Raigarh S/s of PGCIL for wheeling of power from Nabinagar generation project in ER to their traction substation in Chhattisgarh during 29th SCM held at Ahmedabad on 10th Sept. 2009. PGCIL informed that Railway Electrification, Bhubaneshwar has proposed to wheel power from Railways 1000 MW generation project at Nabinagar in ER, being developed by Bharat Rail Bijli Co. Ltd. (BRBCL) to Chhattisgarh through ISTS network. The power supply would be availed at 220 kV level by constructing 220/132 kV substations one each at Raigarh and Raipur and connecting these to PGCIL 220kV Raigarh and Kumahari(Raipur) S/s respectively. The Long term open access has been granted to Bharat Rail Bijli Co. Ltd. (Nabinagar generation project) for transfer of 990 MW. Target beneficiaries Indian Railways (ER: 355 MW, WR: 485 MW, NR: 50 MW) and BSEB (100 MW). The target drawal of 130 MW in Maharashtra, 95 MW in Chhattisgarh, 185 MW in Madhya Pradesh and 75 MW in Gujarat has been indicated by Indian Railways in WR. Member (PS), stated that the above matter was discussed During the 29th meeting of Standing Committee and as a special case the proposal of for connectivity to proposed 220/132 kV at Raigarh and Kumhari of Indian Rlys with existing Raigarh S/s of PGCIL has been agreed. GUVNL representative stated that if the Railways draws the power through State transmission network it would be in order. However, agreeing to the above proposal of Railways will amount to direct connectivity with CTU and might set an improper precedence and may involve payment of cross subsidy surcharge to the concerned State by the above utility. Chairman, WRPC/GESCL remarked whether allowing the connectivity to the Railways as a special case mentioned above would be feasible contrary to the CERC regulations. He, therefore, suggested that Railways might approach CERC and based on the outcome their proposal for connectivity of 220/132 kV at Raigarh and Kumhari of Indian Rlys with existing Raigarh S/s of PGCIL for wheeling of power from Nabinagar generation project in ER to their traction


16

substation in Chhatisgarh may be examined. He requested PGCIL to take the needful action. PGCIL agreed to the same. ITEM No. 4: FREE GOVERNOR MODE OF OPERATION ON ALL GENERATING

be met from the UI cap fund as the project is for system improvement. WRLDC clarified that this will be subject to the approval of CERC.

f) It was suggested to form a PMU group at the RPC level comprising of

representatives of Protection groups from all the constituents of WR, that will look into the analysis of correct/incorrect operation of protection relays during line trippings and other grid disturbances using input from WAMS data which is in milliseconds time frame, study of stability related issues by study group etc. At present the data routing was envisaged at RLDC levels. Hence the data routing should be such that the WAMS PMU data is available to the Protection and Study groups both at the State as well as RPC level. The necessary details of data routing to the SLDC / WRLDC/ Protection and Study PMU groups can be finalized accordingly.

g) It was also suggested that Task Force from the representatives of WR constituents

may be formed which would monitor the progress of the implementation of the proposed WAMS project.

h) Constituents felt that the continuous real time data (24 x 7) should not be provided in

view of the commercial implications. POWERGRID representative agreed to discuss the same with IIT-B and revert back. The data sharing by IIT-B in the above pattern may be during the project implementation duration period only.

5.4 Member Secretary, WRPC stated that the TCC in its meeting held on on 24th Sept. 09 discussed the matter and was agreed that WAMS in WR will be implemented on integrated regional basis. MSETCL will also be the part of this regional WAMS. Above recommendations were further discussed by the WR Power Committee. GM I/C(LD&C), PGCIL informed that the POWERGRID proposed project is a Regional Project. This WAMS project is approved by CSIR (Council of Scientific & Industrial Research) under New Millennium India Technology Leader Initiative (NMITLI), which is a step to promote development of indigenous technology. In this project around 25 no. of PMUs shall be installed at substations/generating stations in the Western Region. The location of PMUs shall be decided in consultation with IIT Bombay who is one of the partners of the consortium. Other consortium partners are TCS and Tata Power. The estimated cost of the project is Rs. 16.75 Crores. POWERGRID share of total estimated cost of the project is Rs. 8.76 Crores. The POWERGRID Share of project


19

cost is for installation of PMUs, Hardware/software at WRLDC etc. The data generated by PMUs shall be available at WRLDC and shall be used by the WRLDC for grid operation as and when they are commissioned. CSIR shall provide soft loan at an interest rate of 3% for implementation of the project, which shall be repaid over a period of ten years in annual installments. The Project completion time has been envisaged as two years for development followed by one year for performance monitoring. Balance amount of the project cost (Rs 7.99 Crs) would be given by CSIR to IITB as grant and as loan to TCS and Tata Power. Tata Power shall be responsible for providing five no of PMUs in Western region. The responsibility for development of software analytics is with IITB and TCS. Developed software shall be used by WRLDC for grid operation. The developed software also has the potential to generate the revenue through IPR, which shall be shared among the Project partners and CSIR. ED (WRLDC) informed that the proposed project is a regional project like any other transmission project of POWERGRID and the benefit would be to all the constituents by way of improved grid operation, and therefore all the constituents should agree for its implementation by POWERGRID. ED (WRLDC) proposed that the UI cap fund can be utilized for repayment of POWERGRID portion of CSIR loan. Chairman, WRPC suggested MSETCL to join the POWERGRID proposed CSIR approved WAMS project as this being a Regional Project and cost of funding is also very low (@3% interest). Member (Power System), CEA informed that the MSETCL project is in the proposal stage only in the National perspective plan for R&D in power sector. The fund under National perspective plan is limited, which is allotted to projects on first come first serve basis. The MSETCL proposal is at 33rd position in the priority list of the projects already proposed for funding under National perspective plan. Member (Power System), CEA also suggested MSETCL to join the POWERGRID proposed Regional WAMS project. After deliberations the WR Power Committee agreed to the above recommendations of the Special meeting held o 17th Sept 2009. Regarding points (a) to (d) of the recommendations above it was agreed that MSETCL shall join POWERGRID proposed Regional WAMS Project. MSETCL however requested that participation of their officials should be ensured in the proposed WAM project at regional level, which was agreed. It was therefore agreed to form a PMU group at RPC level comprising of representatives of Protection groups from all the constituents & WRPC. Under the project proposal the data routing is envisaged only at RLDC level. During deliberations it was further agreed that WAMS PMU data shall be made available at SLDCs, RPC and PMU study groups also. Any additional expenditure incurred to make the PMU data available at SLDC/RPC, shall be separately put up for approval.

In view of above the WR Power Committee approved the implementation of WAMS Project in WR proposed by POWERGRID with consortium partners TCS, IIT Bombay & Tata Power Company limited and repayment of the loan from CSIR shall be through UI cap fund. WRLDC shall approach CERC for necessary approval. In case of non-approval from CERC, the matter will be placed before WRP Committee for further direction. PGCIL/WRLDC may proceed accordingly.

ITEM No.7: TRANSMISSION CHARGES FOR WHEELING OF CENTRAL SECTOR POWER TO DD & DNH THROUGH GETCO TRANSMISSION SYSTEM AND THE BILLING MECHANISM

7.1 Member Secretary, WRPC intimated that on Petition No. 64/2008 and No. 67 / 2008 in the matter of fixation of and adjudication on the transmission charges for use of the Gujarat transmission system for conveyance of Central Sector power to UT of DD & DNH under sections 62 and 79 of the Electricity Act, 2003 and in the matter of Gujarat Energy Transmission Corporation Ltd., the Hon’ble CERC issued final order on 31st July 2009. The Commission directed that the charges applicable for the period 01.04.2004 to 31.03.2009 in accordance with the above order shall be shared in the manner decided in Commission’s order dated 03.02.2009 i.e. as per the existing practice. WRPC Secretariat had accordingly revised the concerned statement of monthly REAs for the year 2004-05 to 2008-09 based on above directions of CERC. The Commission also directed that w.e.f. 01.04.2009 Member Secretary, WRPC shall calculate the charges payable for use of GETCO System in the same manner and shall be shared by WR Constituents as decided earlier by order-dated


21

03.02.2009. The parties are at liberty to approach the Commission for resolving disputes, if any regarding calculation / payment of charges in accordance with law. In the TCC meeting held on 24th Sept. 09, GETCO informed that they are in the process of filing a petition with the Appellate Tribunal for reviewing of CERC order. TCC suggested that since there is no direction from ATE as of now, the fixation of the transmission charges for use of the Gujarat transmission system for conveyance of Central Sector power to UT of DD & DNH, should be done as per the CERC order dated 31.7.2009. WRP Committee noted the same.

7.2 Member Secretary, WRPC stated that during the 10th Meeting of WR Power Committee held on 30th May 2009 the matter regarding billing of transmission charges for wheeling the C.S. Power to UTs of DD & DNH was discussed and it was decided that till such time, any order is issued by the Hon’ble CERC in respect of determination of transmission charges for GETCO System for wheeling the C.S. power to DD & DNH, the present methodology of billing the transmission charges through PGCIL should be continued and the same would facilitate adjustment / recovery of transmission charges due, if any, as the entire record and billing details are available with PGCIL. Subsequently on issue of specific orders by Hon'ble CERC in the matter, the billing of transmission charges in respect of above might be done by GETCO / MSETCL directly, as per REA issued by WRPC.

As the Hon'ble CERC have now issued order dated 31st July 2009 in respect of determination of transmission charges for GETCO System for wheeling the C.S. power to DD & DNH, the matter regarding billing the wheeling charge came up for discussion in 53rd meeting of Commercial sub-Committee of WRPC held on 8th Sept. 09. Representative of MSETCL in the meeting had opined that mechanism for payment of charges towards wheeling the C.S. power to Goa and UTs of DD & DNH was earlier agreed on account of non- connectivity of their respective systems with CTU network because it is the responsibility of CTU to arrange connectivity of the beneficiaries' systems to the ISTS to transmit C.S. power to the beneficiary States. Therefore, the present arrangement of billing of transmission charges in respect of MSETCL / GETCO for transmitting of C.S. power to Goa/DD&DNH through PGCIL, should be continued. GETCO/GUVNL and rest of WR constituents including Goa had also endorsed the above opinion of continuing with the present arrangement. However, PGCIL representative stated that for continuing the existing practice of billing, some working arrangement along with necessary agreement with MSETCL and GETCO would be required to be in place. It was therefore suggested by the Commercial sub-Committee that the matter may to be discussed in the TCC / WRPC for further directions.

The matter was deliberated in the TCC meeting held on 24th Sept. 09 and TCC opined that existing arrangement. of billing of transmission charges in respect of MSETCL / GETCO for transmitting of C.S. power to Goa/DD&DNH through PGCIL monthly billing system should be continued. However, PGCIL representative stressed that for continuing the existing practice of billing, some working arrangement along with necessary agreement with MSETCL and GETCO would be required to be in place.


22

The matter was deliberated and WRP Committee agreed to the above suggestion of TCC and requested PGCIL to continue with the present arrangement.

ITEMS FOR INFORMATION ITEM No.8: ANTICIPATED POWER SUPPLY POSITION IN WESTERN

REGION FOR THE PERIOD FROM SEPT. 09 TO NOV. 09 The anticipated power supply position in the region for the period from September, 2009 to November, 2009 commences with the onset of Rabi season.

10.4 In the TCC meeting held on 24th Sept. 09, upon query by TCC members, ED, WRLDC stated that as per the arrangement, the preparation for the replacement of the existing ULDC scheme shall be taken up after three years and in this activity PGCIL will involve the constituents for preparation of specifications etc. WRLDC further indicated that in the next RPC meeting they would propose suitably the modalities for this activity for discussion and concurrence by the WRPC forum. The issue regarding of levying of 15 % PGCIL service charges, upon query by MPPTCL, on the value of the LTSA contract had come up for discussion in the TCC meeting. PGCIL pointed out this is being done as per their policy. However WR constituents unanimously stressed that since the WRLDC expenditure is borne by them, the above proposed service charges should not be charged. The matter was deliberated by WRP Committee and the Committee did not agree with the proposal of PGCIL for levy service charge in respect of above LTSA. ITEM No. 11: INVESTIGATION ON FAILURE OF 400 KV TRANSMISSION LINES

OF PGCIL DURING MAY-JUNE – 2009 BY THE STANDING COMMITTEE OF EXPERTS

The Standing Committee of Experts on investigation on failure of 400 kV transmission lines of PGCIL has submitted its report, in it’s finding the Committee has finally concluded that the following lines of PGCIL in respect of WR failed due to heavy wind except 400 kV Korba – Bhilai-Ckt-I S/C line:

(i) 400kV Jabalpur-Itarsi D/C line (18 No. of towers) (ii) 400kV Vindhyachal-Jabalpur Ckt-I & II D/C Line (3 No. of towers) (iii) 400kV Korba-Bhilai Ckt-I S/C Line (3 No. of towers) (iv) 400kV Khandwa-Dhule D/C Line (5 No. of towers)

The 400kV Korba-Bhilai Ckt-I S/C Line failed due to action of heavy wind velocity on towers but the main reason was missing of the redundant members due to theft. The Standing Committee of experts to investigate failure of 400 kV transmission lines of PGCIL decided that:

(i) PGCIL will provide hip bracings on all the suspension towers on all transmission lines up to bottom cross arm, keeping in view the priority & importance of the lines.

(ii) PGCIL should also obtain the services of SERC regarding installation of wind measure system as well as downloading of data remotely & its analysis.

The WR Power Committee noted the same.

WRP Committee noted as above.

ITEM No. 18: AUTOMATIC METER READING SOLUTIONS BY M/S BPL 18.1 WRLDC in the 53rd meeting of Commercial Committee held on 8th Sept. 2009 stated that M/s BPL has developed an Automatic Meter Reading (AMR) solution for downloading and transmitting the data from remote locations to RLDCs. The main feature of this solution is that the data will be automatically read from the meter and transmitted to RLDC. WRLDC added that M/s BPL have developed the output text file exactly similar to one created by M/s SML and M/s L&T using their software “SMARTGRID and “VINCOM” respectively and have given three different types of architectures to download and transmit the data from remote location to respective RLDC. WRLDC further stated that a pilot project has been given to M/s BPL by WRTS-I, PGCIL, Nagpur, to connect few meters at 400 kV Seoni S/s for one month with required interface unit so that complete system can be verified for few weeks


29

before it can be accepted completely. WRTS-I, PGCIL agreed to take up the responsibility. As per the detailed budgetary proposal received from M/s BPL, the total cost for 531 Nos. SEMs (405 SML make and 126 L&T make), spread over 92 locations, comes out to Rs. 77.73 Lakhs assuming that dedicated PCs are available in all these locations. In addition to above, cost of TA/DA of PGCIL employee will also have to be borne by the constituents. WRLDC proposed to share the cost of this project in the same manner the cost of SEMs are shared. WRLDC also stated that M/s BPL have agreed to take up this project at few 3 or 4 locations free of cost. 18.2 The above matter was deliberated in detail and the Commercial Committee members unanimously opined that the above project may be initially taken at few 3 or 4 locations at free of cost and based on the experience the decision for implementing the same for all locations will be taken later on. WRLDC suggested Asoj, Koradi or Kolhapur, Korba(W) and Bina or Bhopal locations can be initially taken up by M/s BPL start the project, Constituents agreed to the same. The Committee also suggested WRLDC to other developers also in this project. Chairman, WRPC / GSECL suggested that WRLDC may look for 3-4 vendors for development of the project so as to get better option. ITEM No. 19: ALLOCATION OF POWER FROM SUBANSIRI HEP (2000 MW) OF

ITEM No. 20: PROCUREMENT OF ONE SPARE UNIT OF 50 MVAR SHUNT

REACTOR FOR WR PGCIL representative stated that in view of the system ageing and the failures being experienced, it is proposed to procure one no. 50 MVAR reactor for WR and keep it in a strategic location so that in case of any failure, immediate replacement is possible. The location has been decided based on the critical requirement e.g. State


30

capitals or major load centre and critical operation, based on various condition monitoring techniques or ageing factor.

In view of the criticality of the location in Western Region and number of existing reactors under operation, it is proposed to keep one spare reactor at Itarsi S/S to meet any eventuality, as at present eleven (11) nos. of shunt reactors are under operation at Itarsi S/S (largest no. of reactors in a particular S/S) and four (04) of them are more than seventeen (17) years old. The availability of spare reactor in the region will help in restoration of the failed equipment within minimum possible period and ensuring reliable power supply without over voltage problem, as the reactos are not readily available and repair of a reactor after failure, generally takes around 12 months time due to pre occupation of manufactures with supply of new equipments. The estimated cost of one 50 MVAR Shunt Reactor is approx. Rs 3.25 Crores. The matter was deliberated in the TCC meeting held on 24th Sept. 09 and the TCC suggested that as the procurement of above equipment is to be considered under additional capital expenditure or through O&M expenses. PGCIL may approach CERC directly for necessary approval of the same accordingly. WRP Committee agreed to the suggestion of the TCC and requested PGCIL to approach CERC.

(Action: PGCIL) ITEM No. 21: OPGW CONNECTIVITY TO SUB-STATIONS OF PGCIL 21.1 PGCIL stated that under ULDC project, Fibre Optic (FO) based Wideband communication network has been established. Subsequently, backup communication links on certain sections have also been established. This wideband network of ULDC is available at only selected locations (Total – 25 nodes & Central Sector - 6 nodes) and therefore huge no. of RTUs are still communicating on PLCC. The performance of SCADA system at WRLDC and SLDC is largely dependent on the performance of the communication links. The SCADA committee of Western Region consisting of the members of all the constituents of Western Region and WRLDC reviews the performance and maintenance issue periodically. The committee in their meeting held on 30th June 2009 has recommended that (a) all future transmission lines would have to be equipped with OPGW link as part of construction package and (b) the important and critical lines commissioned subsequent to commissioning of ULDC scheme in WR to be provided with OPGW communication link. Accordingly, POWERGRID proposes to extend the FO connectivity to all its substations in the region. POWERGRID also mentioned that upcoming WAMS technology can be implemented only with FO based communication network. GM I/C (LD&C) POWERGRID mentioned that in case constituents’ substations are also to be provided with wide band connectivity the requirement can be finalized on regional basis. The matter was deliberated by the constituents in the TCC meeting held on 24th Sept. 09 and it was concluded that requirement of FO connectivity is to be examined on case-to-case basis. However, the future transmission lines should be equipped


31

with OPGW link as part of construction package. It was decided that the FO connectivity network for the region shall be finalized by the SCADA committee and thereafter the same shall be put up for the approval of the TCC/WRPC. WRP Committee endorsed the recommendation of the TCC. ITEM No. 22: STATUS OF LTOA APPLICATIOS IN WR

22.1 PGCIL representative stated that in the 11th meeting of WR constituents regarding Long-term Open Access(LTOA) applications in WR was held on 10.09.2009 at Ahmedabad. IPPs who have shown substantial progress for the project as well as scheduled commissioning of the unit as informed by the applicants as well as by CSPTCL/CSPGL were considered for grant of LTOA. Further, IPPs have indicated only target region/beneficiaries, however, they need to firm-up the beneficiaries at the earliest. However, based on the target beneficiaries/regions suitable system strengthening as well as dedicated transmission system have been identified and transmission charges for the system strengthening shall be borne by the respective IPP/applicant till firming-up of the beneficiaries. It was informed that some of the LTOA applicants applied for open access for full capacity and some for net injection. In line with the discussion held during the 28th Standing Committee meeting of WR, since the sharing of pooled regional transmission charges was on the basis of gross generation capacity, therefore, the LTOA applicants would also share the transmission charges accordingly. Wherever, the applicant has applied for part capacity with balance to be supplied through STU system or own consumption, LTOA would be for capacity applied for. However, such applicants would need to account for their full generation capacity with respect to LTOA (STU) + LTOA (CTU) + own consumption. The owing long-term open access applications were discussed and agreed in the 11th meeting of WR constituents regarding Long-term Open Access(LTOA) applications in WR was held on 10.09.2009 at Ahmedabad. 22.2 Bina Power Supply Co.

ITEM No. 23: Evacuation of power from generation projects coming up in Sikkim and Bhutan

23.1 Member (PS), CEA informed that a review of the generation projects in Sikkim, Bhutan and NER along with comprehensive transmission system was informed during the 29th meeting of SCM held on 10th September 2009. The latest schedule of generation projects envisaged to come by the year 2014 is as under:

(a) NER : About 4000 MW ( Lower Subansisri HEP: 2000MW, Kameng HEP: 600 MW, Bongaigaon TPS: 750 MW, Pallatana GBPP: 726 MW)

(b) Sikkim : About 2400 MW ( Chujachen: 99 MW, Teesta-III: 1200 MW,

Jorethang: 96 MW, Tingting: 99 MW, Rongnichu: 96 MW, Bhasmey: 51 MW, Tashiding: 97 MW, Rangit-II*: 66 MW, Teesta-VI: 500 MW, Rangit-IV: 120 MW)

(c) Bhutan : About 1200 MW (Punatsangchu-I HEP),

Other future projects in Bhutan like Mangdechu (670MW) and Punatsangchu-II (990 MW) are expected to be commissioned by 2016

23.2 In order to evacuate the power from the generation projects in NER, Sikkim and Bhutan, a comprehensive transmission scheme has been evolved which consisted of Bishwanath Chariyali(NER) - Agra(NR), +/-800kV, 6000MW HVDC bipole line with 3000MW HVDC converter stations at Bishwanath Charyiali and Agra proposed under “NER – NR/WR Interconnector-I” initially, which has already been concurred by the constituents of NR and WR.. Earlier it was proposed to evacuate power from Sikkim projects by pooling it at Kishenganj and onward transmission to Agra was to be through HVDC. However, now there was change in the proposal and Sikkim power is now proposed to be evacuated through AC network from Kishenganj onward. The location of the proposed HVDC terminal is proposed to be brought to Alipurduar nearer to Bhutan for evacuation of power from projects in Bhutan. The balance portion of the scheme now consists of 3000MW converter station each at Alipurduar and Agra along with loop-in & loop-out of 6000MW HVDC bipole line at Alipurduar. 23.3 The transmission system for evacuation of the above projects had been divided into three parts. The first part is for evacuation of power from the first two projects in Sikkim i.e. Chujachen (99 MW) and Teesta-III (1200 MW). The 2nd part is for evacuation of the next 1100MW of power i.e. total 2400MW from Sikkim generation projects. The 3rd part is for providing the corridor towards NR/WR with adequate reliability and security for the above generation projects in Sikkim as well as help in evacuation of power from Phunatsangchu-I generation project in Bhutan and also initial evacuation of future generation projects in Bhutan like Punatsangchu-II, Mangdechu etc.
