Eagle Battery Energy Storage System

200 Knollwood Road Ext. Town of Greenburgh and Village of Elmsford, New York 10523

The applicant proposes the construction of a Battery Energy Storage System (BESS) and a route for the electrical conduit connecting to an existing substation. on Route 119 The conduit route is located in the Village of Elmsford, and the BESS will be located in the Town of Greenburgh. This energy storage project is properly classified as a public utility structure under the Town's Zoning Section 285-10(4)(b) and therefore is permitted in the R-30 Zone as a Special Use. The BESS is a series of batteries housed in heavy duty storage containers connected to the sub-station that will provide 20MW of capacity to be added to the grid. It is expected to become a critical component during periods of peak energy demand to help fill the void created by the Indian Point Power Plant shutdown in 2021. The Bess has zero carbon emissions. When fully functional, it will produce and store 80MW of electricity that would be enough energy to power 4,786 homes for an entire day before needing to recharge. Battery Energy Storage Systems such as the one proposed, will increase grid efficiency, reliability and reduce the need for traditional carbon-emitting sources of energy, which will benefit the Town and its residents. The Greenburgh-Elmsford facility will be the first in Westchester County. Site Plan and Special Use Permit approvals by the Greenburgh Town Board are required.

DETAILED PROJECT DESCRIPTION

Ferrandino & Associates. Inc. Eagle Battery Energy Storage System Town of Greenburgh, NY

1

A. DETAILED PROJECT DECRIPTION

Proposed Site Use and Applicant Information

Eagle Energy Storage is requesting approval to construct and operate a 20-megawatt (MW) 4-hour battery storage facility. The project will interconnect to the Con Edison electric grid and is designed to operate for 20 years. The facility will be installed on property within the Knollwood Country Club. The battery and related systems will be located on an unused parking lot central to the golf course property in the Town of Greenburgh. A combination of underground cables and overhead power lines will connect the Eagle Energy Storage project to an existing Con Edison sub-station, which is directly across I-287, in the Village of Elmsford. The proposed project site and approximate interconnection run is shown below. The battery storage facility and accessory structures are referred herein as the “project” or “Eagle Energy Storage.”

Figure A-1: Aerial View of Project Site and Indicative Interconnection Run

Tesla megapacks

Eagle Energy Storage will utilize Tesla Megapack battery energy storage systems. Tesla, Inc. (Tesla) is the market leading manufacturer of battery energy storage systems. The battery energy storage systems consist of pre-manufactured “cabinets”.


2

Figure A-2: Rendering of Tesla Megapack

A single Megapack (as pictured above), with concrete foundation, will encompass approximately 272 sq. ft. of project site footprint. A portion of the 272 square feet includes the transformer which would be located adjacent to the battery cabinets and is not shown above. Each Megapack measures approximately 23.38 ft. in length, 5.25 ft. in depth, and 8.27 ft in height. The footprint of a single Megapack is approximately 123 sq. ft. in area and 1015 cu. ft. in volume. The Eagle Energy Storage project will incorporate 28 Megapacks.

Tesla has designed the Megapack with safety as the top priority throughout transit, installation, commissioning, operation, maintenance and decommissioning.

Figure A-3: Rendering of Tesla Megapack (Interior)

According to Tesla, a typical Megapack is “fully pre-assembled and tested and requires no field assembly or external interface”. A Megapack houses the following technology:

• 17 battery modules:


3

o Each battery module contains approximately 12,600 lithium-ion battery cells, DC power electronics, and liquid cooling conveyance Each cylindrical lithium ion battery cells measure approximately 1” in

diameter by 4” in length. Each cell is individually fused, fully sealed and liquid cooled.

• Customer interface bay – a user-accessible bay, inside the Megapack, is designed for operation and servicing. This bay is fully integrated and includes the AC Main Breaker, “Lock Out/Tag Out” switch to electrically detach the DC connection to the Megapack, a status panel and the customers I/O terminals.

• Inverters – includes 70 kVA Powerstage Inverters (also used in Tesla’s existing Powerpack system) and has a removable coolant manifold to facilitate field servicing.

• Thermal management system – contains a cooling system comprised of a closed-loop liquid thermal system within the thermal bay and roof. The thermal system includes pumps, compressor, condenser fans and radiators. The thermal roof maintains operating temperature and utilizes passive deflagration vents. Each element can be replaced on site and the thermal bay subassembly can be removed for off-site maintenance, if needed.

The Megapacks will be anchored to concrete foundations. The battery storage facility will be connected to the Con Edison “Elmsford #2” Substation on Route 119 at a voltage of 13.2 kV. The Megapacks will receive energy through the existing Con Edison grid and store it onsite until needed. Eagle Energy Storage will be a grid resource for peak demand, renewable integration and local reliability.

Battery Maintenance

Tesla has designed the Megapacks to be easily serviceable and should only require maintenance once a month. When a battery within a cabinet requires replacement, the authorized technician will access via the individual cabinet ports. Within the cabinet, the individual battery cells are located within a stacked, drawer-like compartment, which can be pulled outward for access. The worker can then access and service individual battery modules. Any removed battery modules will be disposed of in accordance with local, State and Federal regulations.

Depending on the nature of the service, Strata expects technicians to be onsite no more than a single standard working day per month. Approximately once per year technicians will be on site for 3-5 days to perform annual maintenance.

B. LAND USE AND ZONING ANALYSIS

Introduction

Strata Solar, LLC proposes to situate a Battery Energy Storage System (BESS) on property at the Knollwood Country Club located in both the Village of Elmsford and the Town of Greenburgh, NY (see Figure B-1). The Subject Site for the battery storage system is situated on land next to the parking lot of the Knollwood Country Club in the Town of Greenburgh, with access to the Site from the Village of Elmsford and the Town of Greenburgh. The Land Use and Zoning Study Area (see Figure B-2 below) includes properties within a 750-foot radius from the Subject Site.

Figure B-1: Birdseye View of the Subject Site at Knollwood Country Club with Photos 1-10 showing the major viewsheds around the Subject Site.


2

Figure B-2: 750-foot Land Use and Zoning Study Area from the Subject Site.

Methodology

The land use and zoning analysis that Ferrandino & Associates Inc. (F&A) performed is in accordance with the following methodology:

• Field Reconnaissance

F&A conducted a field visit and photo reconnaissance of the Subject Site and nearby areas on July 17, 2020 to examine the existing land use patterns and built environment within the Study Area and to verify the accuracy of existing land use maps of the Town, Village, and County.

• GIS Mapping

F&A analyzed Town of Greenburgh and Westchester County mapping resources to identify the land uses present in and around the Study Area. F&A produced GIS mapping figures based upon the Town of Greenburgh and Village of Elmsford Zoning Codes, Town, Village, and County GIS data, and field observations reflecting the most current parcel-based land use and zoning designations.


3

• Public Policy Research

F&A reviewed the Town of Greenburgh Zoning Code to analyze the maximum potential development of the Subject Site under the current zoning, as well as the 2016 Town Comprehensive Plan which F&A assisted in preparing.

Land Use and Zoning Analysis

Land Use

The Town of Greenburgh 2016 Comprehensive Plan does not include specific recommendations for the Subject Site. The Subject Site is 1.61 acres of vacant land located next to the parking lot serving the Knollwood Country Club and clubhouse. According to the GIS database of Westchester County and the Town of Greenburgh, the land uses within the Study Area and the Town of Greenburgh are comprised of private golf course use and institutional and public assembly, vacant land, single family residential, and storage, warehouse, and distribution facilities, as well as transportation right-of-way cross over (see FigureB-3 below).

The properties within the Study Area are primarily private golf course use (Knollwood Country Club) and institutional and public assembly use (the New York School for Deaf). The direct distance from the Subject Site to the New York School for Deaf campus is approximately 210 feet, and the direct distance from the Subject Site to the campus entrance is approximately 540 feet. The Subject Site is within a private golf course use. The traffic right-of-way includes Knollwood Road, Old Tarrytown Road and a portion of a service road connecting to the parking lot. The vacant land to the northeast of Old Tarrytown Road is currently a green open space. On the other side of Tarrytown Road are storage, warehouse and distribution facilities which are occupied by Airgas Welding Supplies. Single-Family Residential use abuts the Study Area to the northeast and south which is beyond 750 feet from the Subject Site, and it contains mostly single-family homes which are not within the Study Area.

Figure B-3: Land Use in the Study Area

Photos 1-10 below show the major viewsheds around the Subject Site (see Figure B-1 for the viewshed locations). The Knollwood County Club clubhouse is located in the west portion of the Study Area (see Photo 1). The clubhouse is very close to the parking lot, with multiple parking entrances on the backside of the building (see Photo 2). There is a service road connecting the Knollwood Road exit to the clubhouse and the parking lot. To the west of the service road is the clubhouse, while to the east of the service road is the parking lot, with some shade trees between the road and the parking lot (see Photo 3). The Metropolitan Golf Association (see Photo 4) is adjacent to the intersection of Knollwood Road and Old Tarrytown Road. The other entrance to the parking lot is from Old Tarrytown Road (see Photo 5). Knollwood Road goes through the Study Area (see Photo 6), with the Knollwood Country Club to the west and the New York School for Deaf (see Photo 7), which is shown as the institutional and public assembly use in Figure C. At the very south of the Study area is the storage, warehouse, and distribution facilities use, which is occupied by a company named Airgas Welding Supplies (see Photo 8). To its south is the transportation, communication, and utility use occupied by Fleet Pump & Service Group Inc (see Photo 9). Further to the south on Knollwood Road, there is a large office building (CrossWest) near the intersection of Knollwood Road and I-287 (see Photo 10).

Since the Town of Greenburgh 2016 Comprehensive Plan does not include specific recommendations for the Subject Site, there is no land use change needed for the Proposed Project.

Zoning

As shown in Figure B-4 below, the Study Area is comprised of R-30 One Family Residence, R-20 One Family Residential and Light Industrial (LI) zones. The Subject Site is located in the R-30 zone. The businesses shown in Photos 8-10 are all in the LI zone. According to Town Code, §285-10A(4)(b), the R-30 zone allows public utility structures as a special permitted use by the Town (see letter dated August 27, 2020 from Mila Buckner, Esq. attached herein). The proposed energy storage facility, which will provide access to essential services by stabilizing the electricity supply that is administered by the local utility company’s service, is classified as a public utility structure. Therefore, the proposed Eagle Energy Storage project is a special use that is subject to review and approval by the Town Board.

Timothy Lewis Office of the Town Attorney 177 Hillside Avenue Greenburgh, NY 10607

Re: Intent to Submit a Special Use Permit Application for an Energy Storage Project at 200 Knowllwood Rd Ext, Elmsford, NY 10523

Dear Mr. Lewis: This office represents Strata Solar in connection with the development of the

Eagle Energy Storage Project (the “Project”) located at 200 Knollwood Rd Ext, Elmsford, NY

10523. As explained in further detail below, it is Strata’s intent to submit to the Town Board for

Project approval a site plan review as well as an application for a special use permit as is

consistent with the Town of Greenburgh Zoning Ordinance (“Town Code”) § 285-53 and § 285-

10(4)(b).

(1) The Project

Strata is proposing to install a 20 MW Energy Storage System on a secluded piece

of the Knollwood Country Club parking lot as described in the site plan attached hereto as

Appendix A. When built, the Project will look similar to a shipping container as illustrated in the

Tesla Diagram attached hereto as Appendix B.

(2) Use Classification

August 27, 2020 Page 2 The Project is located within the Town of Greenburgh’s R-30 district. Special

uses allowed in the R-301 district include public utility structures:

Public utility structures. Public utility structures and utility rights-of-way, excluding utility business offices, garages or storage yards, and electric substations, when said facilities are needed to serve the Town or the immediate neighborhood, subject to a determination by the Town Board that no other reasonable location in this district or in a less restrictive district can be utilized for the proposed facility and further subject to such conditions as the Town Board may deem appropriate for the protection of adjoining uses and of the character of the given district. However, antennas which comply with the conditions set forth in § 285-37 of this chapter shall be permitted pursuant to the provisions of that section. (See Town Code, §285-10A(4)(b)).

This energy storage project is properly classified as a public utility structure and

therefore is permitted in R-30 as a special use. Case law in New York holds that public utilities

include the obvious – electric, gas, water – but also the less obvious, such as cell phone service

and related antennae. Cellular Tel. Co. v. Rosenberg, 82 N.Y.2d 364, 371 (1993). This case

reads, in relevant part:

A “public utility” has been defined to mean “a private business, often a monopoly, which provides services so essential to the public interest as to enjoy certain privileges such as eminent domain and be subject to such governmental regulation as fixing of rates, and standards of service” (2 Anderson, Am. Law of Zoning § 12.32, at 568–569 [3d. ed.]). Characteristics of the public utility include (1) the essential nature of the services offered which must be taken into account when regulations seek to limit expansion of facilities which provide the services, (2) “operat[ion] under a franchise, subject to some measure of public regulation,” and (3) logistic problems, such as the fact that “[t]he product of the utility must be piped, wired, or otherwise served to each user * * *[,] the supply must be maintained at a constant level to meet minute-by-minute need[, and] [t]he user has

1 See Town Code §285-11A(2), stating special permit uses for R-30 One-Family Residence District include all uses permitted in the R-40 District as specified in §285-10A(2).

August 27, 2020 Page 3

no alternative source [and] the supplier commonly has no alternative means of delivery” (Id., at 569).

Based on the analysis above, the Court concluded that a cellular telephone

company qualified as a “public utility,” and that “the construction of an antenna tower in a

residential district to facilitate the supply of cellular telephone service is a “public utility

building” within the meaning of a zoning ordinance.” Id.

Applying the Rosenberg standard, courts have consistently held renewable energy

facilities, whether owned by a utility or by a private company, are public utility uses under New

York zoning law. See W. Beekmantown Neighborhood Ass'n, Inc. v. Zoning Bd. of Appeals of

Town of Beekmantown, 53 A.D.3d 954, 956 (3d Dep’t 2008); Wind Power Ethics Group

(WPEG) v. Zoning Bd. of Appeals of Town of Cape Vincent, 60 A.D.3d 1282, 1283 (4th Dep’t

2009).

Given this addition to the already clear Rosenberg analysis, it is a common sense

interpretation that the Project, which is part of the delivery process for a traditional utility under

Rosenberg, qualifies as a public utility or public utility structure. The Project will provide access

to essential services by stabilizing the electricity supply that is administered via a local utility

company’s service. This project, and indeed all grid improvements, storage projects, and

renewable energy projects, are urgently necessary not only to meet the minute-to-minute needs

for reliable electricity, but also to comply with State policy and help accomplish the State’s

renewable energy commitments. Furthermore, storage projects such as the one proposed

increase grid efficiency, reliability and reduce the need to rely on traditional carbon-emitting

August 27, 2020 Page 4 sources of energy to the benefit of the Town and its residents. As such, the Town can and should

consider the Project a public utility structure.

(3) Approvals

The Town Board has authority over the review and approval of this special use

pursuant to the Town Code § 285-10A(4)(b). Under Town Code § 285-53, the Project requires

Town Board site plan review prior to special use approval.

Strata intends to submit an application for site plan review to the Town Board

along with a special permit application. Please let us know if you advise an alternative course of

action.

VISUAL IMPACT ANALYSIS/NEIGHBORHOOD/COMMUNITY CHARACTER ASSESSMENT

C. VISUAL IMPACT ANALYSIS/NEIGHBORHOOD/COMMUNIITY CHARACTER ASSESSMENT

Introduction

Taking into account surrounding uses, densities, heights, scale, topography and building architecture, and building upon the analysis and conclusions of Addendum B, the purpose of this analysis is to assess the impact of the proposed Battery Energy Storage System (BESS) on the surrounding neighborhood and community character of the Town of Greenburgh and the Village of Elmsford. F&A analyzed the character of the area surrounding the Project Site including the Knollwood Country Club property, local residences and businesses, institutions, municipal facilities, parking, services and transportation, to determine the impact of the proposed BESS on the community and its compatibility with the neighborhood. As a “public utility” under the Greenburgh Zoning Code, the BESS is a permitted use in the R-30 One Family district (see letter dated August 27, 2020, from Mila Buckner, Esq. in Addendum B).

Neighborhood/Community Character Assessment

The BESS Site is located on 1.61 acres of vacant land next to the parking lot serving the Knollwood Country Club and clubhouse. The property is primarily a private golf course use (Knollwood Country Club) with surroundings that include an institutional and public assembly use (the New York School for Deaf); traffic right-of-way on Knollwood Road, Old Tarrytown Road and a portion of a service road connecting to the parking lot; and vacant land to the northeast of Old Tarrytown Road that is currently a green open space. On the other side of Tarrytown Road are Airgas Welding Supplies storage, warehouse and distribution facilities and there is an area of mostly single-family homes on the very edge of the 750-foot Study Area.

Once the system is operational, there will be almost no emissions or traffic generated; one vehicle is required to monitor the site and will only be present roughly once per month. The connecting cables to the Con Edison sub-station in Elmsford will be one of two options. Option A has the interconnection run all underground. Option B, which is the preferred cable route of Knollwood Country Club, is a partial above-ground option that ties into existing telephone poles, limits soil disturbance and reduces interference with below-ground utilities. The interconnection run in Option B is primarily overhead and then routed underground below I-287 (see Figure C-1). The overhead connection run will be placed so the existing vegetation, mature trees, as well as the existing nets surrounding the driving range, will mitigate and screen it as much as possible (see Photo 1). The switchgear will be located on a portion of vacant land adjacent to I-287 and will be screened from view by existing trees.


2

Figure C-1: Option A and Option B locations of the Interconnection run.

Since the BESS is contributing to the renewable energy capabilities of Con Edison in this part of Westchester, its impact on the power grid will be substantial and will allow for reduced costs associated with meeting peak electric demands, such as on hot summer days, to help keep critical systems online during an outage. In addition, it directly supports clean energy and climate goals which will have a positive effect on the quality of life in Greenburgh, Elmsford and the rest of Westchester County.

The Subject Site will be accessed from the driveway in the parking lot. Currently, the Subject Site is visible from the parking lot (see Photo 3). Since the clubhouse and the service road (between the parking lot and the clubhouse) are higher in elevation than the parking lot and the Subject Site, there is a viewshed from the clubhouse toward the Subject Site (see Photo 4). Although in

the existing condition some trees mitigate the viewshed, there will be some visual impact on the clubhouse. Standing on the golf course looking south toward the Subject Site, the view is screened by the trees (see Photo 5). The grove between the Subject Site and Knollwood Road is dense enough to block the views from Knollwood Road to the Subject Site (see Photo 6).

Site Design

The schematic design below shows the layout of battery storage units within the Subject Site, as well as the site design, architectural character and landscape design of the BESS. The front of the Site will be fenced and landscaped to buffer the units from the parking lot and the clubhouse.

7. Birdseye view and ground view renderings of the proposed BESS superimposed on the Subject Site.

Photos 8-10 below show the perspective renderings of the proposed BESS from the parking lot. The only access to the proposed BESS will be from the parking lot, with a fence enclosing the BESS (see Photo 8). There will be a landscape buffer between the parking lot and the BESS to mitigate the visual impact on the parking lot and the clubhouse (see Photos 9 and 10). Photo 11 shows a sample of the battery storage unit, known as Megapack, which will be similar to the units to be installed in the Knollwood BESS.

Findings and Conclusions

The Subject Site is surrounded by trees on the northern, eastern and southern sides which screen the views from Knollwood Road and reduce the views from the golf course grounds to the north of the Subject Site (see Figures C-1 & C-2 and Photos 3-6). Thus, the proposed BESS has no visual impact on Knollwood Road and has very limited visual impact on the golf course grounds to the north of the Subject Site.

On the western side of the Subject Site, due to the elevation of the Subject Site being lower than the clubhouse, there will be a viewshed from the clubhouse toward the Subject Site. The schematic design proposes planting trees or other landscaping in front of the BESS to buffer and partially screen the view from the clubhouse. The existing trees on the service road next to the clubhouse will mitigate some views toward the Subject Site (see Photo 4). Although these design techniques and existing conditions will mitigate the visual impacts of the proposed BESS, the project will still be partially visible from the clubhouse.

In Option A the interconnection will be all underground and will cause no visual impact. In Option B, the majority of the interconnection run will be above ground with a portion of the interconnection run placed under-ground below I-287and continue below-ground until a point west of the Knollwood Driving Range and then installed on utility poles. The proposed electric poles will be placed such that the existing vegetation and the view of the poles will be mitigated, as much as possible, by a screen of existing mature trees. There are some existing electric poles on the Knollwood Road Extension near the driving range similar in nature to the proposed power lines (see Photo 2). The project proposed utilizing the existing poles or pole locations where possible to accommodate the interconnection route, minimizing the use of new poles. The connection run will have minimal visual impact on the club grounds and no impact off site. The switchgear will be located on a portion of vacant land adjacent to I-287 and will be screened from view.

D. SOCIO-ECONOMIC AND MUNICIPAL SERVICES IMPACT ANALYSIS

Introduction

The socio-economic and municipal services impact analysis (Analysis) utilizes information from the Applicant to help determine various impacts associated with the development of both Sites: the battery installation site in the Town of Greenburgh at Knollwood Country Club and the switch gear location site off of Route 119 in the Village of Elmsford.

Project Profile

The Applicant proposes to situate a Battery Energy Storage System (BESS) on unused land at the Knollwood Country Club in both the Town of Greenburgh and Village of Elmsford, directly across I-287 from the Con Edison Sub-station in the Village of Elmsford. The BESS, considered a public utility under the Town’s Zoning Section 285-10(4)(b), is a series of batteries housed in heavy duty storage containers connected to the sub-station that will provide 20MW of capacity to be added to the grid. It is expected to become a critical component during periods of peak energy demand to help fill the void created by the Indian Point Power Plant shutdown in 2021. The BESS has zero carbon emissions. When fully functional, it will produce and store 80MW of electricity that would be enough energy to power 4,786 homes for an entire day before needing to recharge. Battery Energy Storage Systems, such as the one proposed, will increase grid efficiency, reliability, and reduce the need for traditional carbon-emitting sources of energy, which will benefit the Town and its residents. The Greenburgh-Elmsford facility will be the first of its kind in Westchester County.

Economic Benefits

The project will generate temporary and permanent benefits directly related to project construction and operations. The Applicant estimates it will spend in excess of $5,000,000 in construction expenses, excluding the energy storage equipment itself. It is also estimated that the BESS project will generate Westchester County sales tax (including the Westchester County Transportation District tax) and New York State sales tax during construction, a portion of which will accrue to the Town of Greenburgh and Village of Elmsford. Permanent and Construction Jobs Generally speaking, temporary (construction) and permanent (ongoing) jobs both produce positive economic impacts. It is estimated that this project will generate 20-30 construction jobs during the construction period of six (6) months. The Applicant estimates that $2 to 2.5 million will be allocated for labor costs and approximately an equal amount ($2-2.5 million) is estimated for materials, fees and other expenses. The Applicant typically pays prevailing wages for its projects and is committed to utilizing local contractors, vendors and suppliers where possible. Once fully constructed, the subject facility will be unmanned, with only periodic on-site monitoring by the Applicant.


2

Indirect Spending

Indirect impacts from job creation (temporary construction jobs) include earnings/ spending that will be generated in the local economy as a result of the direct on-site project activity. Indirect (spin off) impacts are typically generated elsewhere in the local economy at off-site locations. It is anticipated that during the construction phase, spending will circulate in the local economy by utilizing local vendors and suppliers for materials. Secondary spending will also occur by workers who will patronize nearby restaurants, coffee shops, delis, retail establishments and other service -oriented locations. Municipal Services Impacts Water, Sewer & Solid Waste Disposal

There will be minimal impacts on these Town and Village services. Waste generated during construction will be properly disposed of by the construction crews. Once operational, there will be no need for sewer & solid waste disposal at this Site. It is estimated that Site landscaping will use a small amount of water to establish plantings, but the amount used will be negligible compared with the landscaping usage of the existing golf course. Permanent irrigation of the landscaping plants is not anticipated.

Police, Fire & Medical Services

Aside from limited use during construction, it is not anticipated that police, fire and medical services will be needed at the Subject Site. It is assumed that the Town and Village of Elmsford police and fire departments will review the proposed project for compliance with all applicable safety measures as part of the permit approval process. The proposed Tesla Megapack System includes multiple redundant fire safety features, including software that will automatically shut down the system in the unlikely event that the system begins to overheat. In addition, the system will be remotely monitored 24/7 and will be shut down manually if any readings from the system are out of range for normal operations.

Overall Socioeconomic Impacts of the Project Overall, the proposed BESS project will have positive economic impacts on the Town of Greenburgh and the Village of Elmsford and the surrounding area. The project will result in the location of a Battery Energy Storage System that will assist in filling the gap in renewable energy sources when Indian Point goes permanently off-line, and provide back-up electricity to the grid. During construction, it will produce 20-30 construction jobs, which will generate additional spending in the local economy. In addition, it will add to New York State’s sales tax coffers and to Westchester County’s sales tax revenue, a portion which shall accrue to the Town of Greenburgh and Village of Elmsford. The Applicant will also, to the extent possible, hire qualified local contractors, vendors and suppliers.

E. TRAFFIC AND PARKING IMPACT ANALYSIS

Existing Conditions:

Location

The proposed Eagle Battery Energy Storage System (BESS) Project is located within the

Knollwood Country Club, which is in both the Town of Greenburgh and the Village of Elmsford,

NY in Westchester County. The actual site of the battery storage area lies in the Town, while

cables will be installed through the Elmsford section of the Country Club and ultimately crossing

I-287 to an existing Con Edison sub-station on Route 119.

Two aerial views of the Project are shown below. Figure E-1 shows the location within the Club

property as well as two optional approximate cable routes across the property to the I-287 right-

of-way where cables will cross to the Elmsford Con Edison sub-station fronting on Route 119.

Option A would be all underground from the BESS Site to the sub-station. Option B would be all

aboveground except for the I-287 crossing. Option B is the preferred cable route. More detailed

descriptions of the cable routes are included in Addendum C. The insets in Figure E-1 show

examples of typical switchgear and transformer equipment.

Figure E-2 is an April 2007 aerial of the proposed storage site which, as can be seen, was once

a tennis court and not part of the Club’s parking supply. Evidence of the tennis court remains also

was observed during the site survey.

TRAFFIC

Roadway Access

The primary access road serving the Country Club site is the Knollwood Road Extension. The

Extension intersects Knollwood Road, which is a designated State Road – NY-100A. Near the

Project Site, Knollwood Road has one travel lane in each direction (generally north/south) with a

posted speed limit of 30 mph. NY-100A continues south through the Town of Greenburgh where

it ends at Central Park Avenue (NY-100). Near the Subject Site, NY-100A intersects Old

Tarrytown Road, the on and off ramps from I-287 (Interchange 4) and Tarrytown Road (NY-119).

To the north, NY-100A continues through Greenburgh, where it ends at the intersection with NY-

100/NY-100C.

The extensive system of highways and State arterials in the vicinity of the Subject Site will provide

for easy access to/from the regional area.

Existing Traffic Volumes

Existing traffic volumes on Knollwood Road were obtained from the New York State Department of

Transportation (DOT) Traffic Volume Report. The relevant pages from those Reports are

contained in Attachment E-1 and are summarized in Table E-1, below:

*Source: NYS Department of Transportation (DOT) – Traffic Count Hourly Report: June 2015

**Volumes represent Annual Average Daily Traffic (AADT) – Volumes adjusted for seasonal variations

The DOT Hourly Report is from June of 2015 and shows that there are just under 10,000 vehicle

trips per day combined in both directions on Knollwood Road. The peak hour volumes were

recorded as high as 942 vehicles combined in both directions.

In addition, data from the State’s 2018 Volume Report include the previous June 2015 counts

and, because no new counts were completed by DOT since 2015, that data also includes

estimates for 2018. This information indicates that little traffic growth was expected to occur on

Knollwood Road in the last four to five years.

Proposed BESS:

Description

The proposed system will provide 20 MW of capacity which will allow the charging of batteries

during off-peak times as well as storage of other renewable energy sources such as excess solar

being produced at other off-site facilities. The battery and related systems will be located in an

area once used as a tennis court and which now serves as an area for occasional additional

parking. The Project Site is within the boundaries of the golf course property, which is directly

across I-287 from the Con Edison Elmsford Substation on Route 119.

The Elmsford substation has substantial capacity and is a key node for power flows from upstate

down to the local community, and will become a critical component during periods of peak demand

as it will help to backfill the 1,000 MW void created by the Indian Point Nuclear Power Plant going

off-line in 2021.

Potential Traffic Impacts

During Construction

� During construction of the new storage system, the Knollwood Road Extension will serve

as the access for worker and truck trips. Both workers and especially trucks will be

directed to access the Extension from the south, i.e., construction traffic will be mostly

oriented toward I-287 and Route 119 via Knollwood Road (Route 100A). The probable

construction staging and expected numbers of worker and truck trips are summarized in

Table E.2 below.

4


� Workers will park on-site as there is sufficient space on the Site to accommodate the

construction vehicles. Excavation equipment will be brought to the Site when required

and will be directed to remain on-site until no longer needed. Hauling truck traffic will

occur with the delivery of various construction material and ultimately the battery

containers. A crane will be utilized to set the Megapacks in place. A summary of the

anticipated construction traffic trips is included in Table E-2.

4 Augmentation n/a n/a n/a 1-2 per yearSource: Strata Solar, LLP, July 2020

1) Truck trips may be clustered for material delivery or hauling; refer to notes below.

Phase 1: Site Construction – will consist of construction of the Site improvements, the storage

cabinets, and the ancillary substation. During this Phase, no more than 18 workers are expected

to be on-site per day. In fact, on most days during this Phase, the workforce is expected to be

about ten workers. Assuming some car-pooling, we estimate between nine and 15 workers’

vehicles per day. When compared to the existing 900-plus peak hour traffic volumes and the

nearly 10,000 daily traffic volumes, this level of additional traffic will not impact traffic conditions

on Knollwood Road.

The construction of the project is estimated to include the import/export of materials from the Site.

In total, approximately 1,500 to 2,000 cubic yards (cy) of materials, i.e. gravel/stone, soil, etc. are

estimated to be transported to or from the project site. Based on the assumption that dump trucks

will be used that can haul 20 cy of material, this would require a total of 75 to 100 truck trips to

facilitate site construction. Hauling of material is assumed to be evenly distributed during the

duration of construction but may be clustered at times when required during grading or excavation

operations.

Phase 2: Battery Delivery – will consist of the scheduled delivery of the lithium ion batteries to the

Site once the storage cabinets have been installed. There will be gaps in the delivery days,

therefore the traffic associated with this activity will be scheduled but will not occur on a continuous

daily basis during this Phase. No more than eight workers are expected to be on-site per workday.

The Delivery Phase will generate approximately four to six trips per day – including trucks. Like

Phase 1, this level of additional traffic will not impact traffic conditions on Knollwood Road.

A crane will be utilized to facilitate placement of the batteries on the Site. The mobile crane will

be temporarily situated on the Site and is not anticipated to impact parking for the Country Club.

The crane will remain on the site until the Megapacks are placed. Due to the costs associated

with crane rentals, the duration the crane will be on-site will be kept to a minimum and is estimated

to be less than two (2) weeks.

5


Phase 3: Interconnection and Crossing I-287 – will consist of installing the electrical conductors

from the Con Edison Substation to the BESS facility. An underground conduit or casing will be

used to facilitate crossing the I-287 corridor. The approximate location of the crossing is shown

in Figure E.1, above. The north side of the crossing is within the Country Club property and the

south side is at the Con Edison Substation, which fronts on Route 119 in the Village of Elmsford.

The New York State Thruway Authority and Department of Transportation are the relevant

approval agencies for the I-287 crossing. The following are the general directives for underground

utility crossings taken from a publication titled “New York State Thruway Authority – Design and

Construction Requirements for Underground Crossings of Mainline Pavement and Shoulders, by

the Office of Real Property Management:”

Underground crossings of Authority Property shall be performed in accordance with the New York State

Department of Transportation (NYSDOT) “Requirements for the Design and Construction of Underground

Utility Installations Within the State Highway Right-of-Way” and the American Association of State Highway

and Transportation Officials (AASHTO) publication, "A Policy on the Accommodation of Utilities Within

Freeway Right-of-Way," current edition, shall apply, except where specified otherwise by the Authority.

The Applicant will abide by these applicable standards and the construction within the Right-of-

Way (ROW) will be permitted and overseen by the Agencies. It is anticipated that the installation

within the ROW will be accomplished by directional drilling or boring methods and will mostly be

conducted outside the ROW itself. Worker activity within the I-287 ROW is estimated to be

minimal, and it is assumed that any work within the ROW itself will likely require nighttime

construction operations.

Installation of the remaining interconnection route on the Country Club property will involve limited

trips on Knollwood Road and Route 119. Anticipated traffic volumes will be low – as shown in

Table E.2, above, and, like Phases 1 and 2, traffic conditions on surrounding streets will not be

impacted.

Phase 4: Augmentation – will consist of necessary upgrades or replacements at the end of years

1, 5, 15 and 20. Augmentation will generate 1 or 2 truck trips to complete the work; this level of

additional traffic will not impact traffic conditions on Knollwood Road.

After Construction

The Battery Storage area will be unmanned. There will be no daily traffic associated with the Site.

On occasion – approximately once per month – there will be a technician visit via the Knollwood

Road Extension. These visits will occur during the day (non-peak periods) and are meant only to

check that no unusual conditions or issues have arisen. Monitoring trips that may note such

issues may be followed by a limited series of maintenance trips over the course of a day or two

to correct the condition if necessary.

PARKING

As noted, the Eagle BESS will be unmanned, generating a possible single trip per month to the

Site by facility operators. Those are the only trips to be made on a “regular” basis. All parking and

unloading will be accommodated on the pad site within the gated driveway at the north end of the proposed

storage system. There will be no on-street parking.

6


Parking for the Country Club will not be impacted. The parking requirements for the Club were

established based on the Village of Elmsford Zoning Code. We note that the site of the BESS is

an old tennis court (see Figure E.2, above). Because the project site was originally used as a

tennis court and not for parking, we conclude that the use of the site for the BESS will not eliminate

any Country Club parking spaces required by Code.

CONCLUSIONS:

The Project consists of installing a passive energy storage system. The traffic impacts as

described herein are minimal and are limited to construction operations. Once completed, the

Eagle BESS will not generate additional daily traffic. As a result, it is our considered professional

opinion that the Project, as planned, will not impact traffic conditions on Knollwood Road (NY-

100A) or any nearby intersecting streets and driveways. No mitigation is required.

F. ENVIRONMENTAL RESOURCES IMPACT ANALYSIS/ASSESSMENT

Introduction

This Environmental Resources Assessment utilizes information from the Applicant to help determine environmental impacts associated with the development of both Sites: the battery installation site in the Town of Greenburgh at Knollwood Country Club and the switch gear location site off of Route 119 in the Village of Elmsford. The proposed Eagle Battery Energy Storage System (BESS) will be situated on land owned by Knollwood Country Club. This 20MW/80MW project will interconnect to Con Edison’s Elmsford substation via an underground cable that will cross I-287 at Route 119 in Elmsford. One section of the cable, interior to the golf course, may be above ground. Construction for the BESS is projected to take six (6) months and it is anticipated that construction will begin in mid- 2021 and that the BESS will be operational in early 2022.

Energy storage is critical to the clean energy future of New York. As renewable power sources, like wind and solar provide larger sources of electricity, storage will allow clean energy to be available when and where it is most needed. By continuing to invest and build a cleaner grid, energy storage will allow for the better use of existing resources more efficiently and with fewer emissions, especially during periods of peak demands such as on hot summer days.

Beginning in 2009, the Applicant has completed more than 170 energy projects throughout the United States and has developed over 100MW of energy storage projects since 2016. This is the Applicant’s first project in Westchester County and when, approved, it will be one of the first large scale energy storage projects in Con Edison’s territory.

The BESS utilizes Tesla Megapack battery energy storage systems, the leading manufacturer of battery energy systems on the market. Each megapack measures approximately 23.38 ft in length, 5.25 ft in depth and 8.27 ft in height. These megapacks are designed with safety as the first priority and ensure safety throughout transit, installation, commissioning, operation, maintenance and decommissioning. See Figures F-1 and F-2 below.

Figure F-1: Rendering of Tesla Megapack.

Impacts to Wetland Areas

The Subject Site is located on a partially paved area that previously was utilized as a tennis court. A small Federal wetland area (regulated by the U.S. Army Corps of Engineers) was identified adjacent to the Subject Site that was delineated by North Country Ecological Services (NCES) in October 2019. The wetland drains into a small stream that is piped under the parking lot adjacent to the Subject Site. Refer to the attached letter from NCES dated February 6, 2020 which includes photos and a description of the small wetland area.

Pursuant to Town regulations, a 100-foot buffer is implemented around wetland areas and requires a wetland permit to impact or work within the buffer. Based on the prior use of the Subject Site as depicted in Figure E-2 (included in Addendum E Traffic and Parking Impact Analysis) and the current Site conditions, a portion of the wetland buffer area has already been impacted by prior disturbance. As part of the BESS development project, a portion of the previously impacted buffer area will be restored to natural vegetation, as it will be located outside of the secure fence perimeter. There are no new impacts to the wetland buffer as a result of the project, and the project will actually result in a reduction in buffer impacts compared with the current condition of the Site. Refer to DWG. NOS. C-101, C-120 and C-132 included within the site plan submission package for more information regarding the wetland buffer impact area.

It should also be noted that BESS equipment and site layout were designed to locate all equipment outside of the 100-foot wetland buffer area. As part of the current site design, the only items that encroach upon the buffer area include the gravel drive area (located on a smaller footprint than the existing tennis court) and the security fence

Endangered Species

An endangered species review was conducted for the Subject Site and the immediate surrounding area by NCES in October 2019. As part of the review the U.S. Fish and Wildlife Service (USFWS) and the New York State Department of Environmental Conservation (NYSDEC) were consulted with regard to Threatened and Endangered Species and Critical Habitats on and around the project area.

Figure F-2: Rendering of Interior of Tesla Megapack.


3

The USFWS indicated that there are no Threatened and Endangered Species or Critical habitats on record for the Subject Site. The NYSDEC indicated that the Kentucky Warbler, a protected songbird in New York, was previously recorded at Westchester County Community College grounds. The habitat where the Kentucky Warbler resides is not found within the Subject Site. The review by NCES concluded that “…there is no endangered, threatened, and or unique habitat communities were present with the Project Area. The project will not entail development and/or ground disturbance within pristine, natural areas that would provide habitat for rare species. The project, as proposed, is within previously disturbed/manipulated land that has been landscaped for the golf course and Knollwood Country Club.” (See letter dated December 5, 2019 from United Stated Department of the Interior and letter dated December 24, 2019 from the New York State Department of Environmental Conservation) attached herein.

Site Disturbance, Erosion Control & Steep Slopes

The proposed BESS project will include installation of electrical utilities and site preparation which will require ground disturbance. The total disturbance for the project area is estimated to be approximately 21,247 square feet, or less than 0.5 acres. An erosion and sediment control (E&SC) plan was developed for the Site to prevent transportation of sediment off-site during construction operations, and is included as DWG. NO. C-120 within the Site Plan submission package. The E&SC measures include a construction entrance, silt fence, straw wattles and erosion control blankets. These methods will be utilized to prevent off-site migration of sediment and will be maintained throughout the duration of construction. It should be noted that as the Site disturbance is less than 1-acre, a NYSDEC SPDES General Permit for Stormwater Activities is not required.

The 1.61-acre project area is situated at the base of a sloped area which includes slopes that range from 0% to 35%+. An analysis of the slopes within the project area is included on DWG. NO. C-101 and is included within the Site Plan submission package. The project area was developed as a lease-parcel of a much larger parcel owned by the Knollwood Country Club. As analysis of the entire parcel would be impractical, the steep slope analysis was performed solely for the lease parcel area.

The results of the analysis indicate that approximately 64% of the disturbed area is located on slopes between 0-15%, with an additional 30% located on slopes less than 35%. Only 6% of the total disturbed area includes development on slopes greater than 35%, and this area is supported by a gravity retaining wall with a maximum height less than 16 feet.

Vegetative Impacts

A limited tree survey was conducted for the Subject Site in accordance with the Town Tree Removal Permit requirements. Based upon the survey, there are a total of 48 trees with 6-inch or larger calipers within or adjacent to the disturbed area that would require removal as part of the project. The trees were noted to be in generally good condition, with some creeping vines and poison ivy present throughout. In general, the trees did not appear otherwise diseased.

The Subject Site is located at the base of a hill and is surrounded by vegetation on three sides. There are no trees present on the Site between the Subject Site and the adjacent parking lot. The


4

removal of the trees would be concentrated on the eastern side of the Site (towards the hill), with some trees subject to removal to the south.

Based on the location of the trees with reference to the Site, the tree removal is not anticipated to have a visual impact outside the golf course and will have a minor impact within the Site itself. As there are no existing trees located between the Subject Site and the existing parking lot or clubhouse, there is no loss in screening in this area.

In addition, as the Subject Site is located at the base of a hill, it is downslope of the nearby greens, and the tree removal is not anticipated to impact screening from adjacent holes. As such, the only impacts anticipated are related to the tree canopy visible from the parking lot and clubhouse. There are no visual impacts anticipated outside the golf course area.

Landscaping bushes and smaller plantings are currently proposed in the area between the Subject Site and the existing parking lot, to aid in the site screening.

Floodplain Area

A review of the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) panels was conducted to ensure that the BESS equipment would not be installed within a floodplain area. Pursuant to FIRM Panel 0266F Map Number 36119C0266F (attached to this Addendum) the Subject Site is located partially within Zone AE, a Special Flood Hazard Area subject to inundation by the 1% Annual Chance Flood (100-year storm event) with a known elevation of 270 feet (based on USGS Datum). The FIRM Panel has an effective date of September 28, 2007 and appears to be the most updated floodplain document available for the project area.

It should be noted that the floodplain area is situated around the nearby small stream that is conveyed beneath the existing parking lot via a 64-inch culvert. Based on a review of the firm panel, it is assumed that the existing parking lot acts as a floodway when the capacity of the 64-inch culvert is exceeded during the 1% change storm event.

A detailed topographic survey of the Subject Site was performed by Insite Northeast Engineering & Land Surveying, P.C. (INE) and was utilized for the development of the project site plans. Based on the existing topography, the existing parking lot has an average elevation of 270 feet, while the project area has an existing elevation greater than 272 feet. The elevation difference is readily visible from the parking lot, as the project area is situated several feet above the parking lot. Refer to the Existing Conditions Plan included as DWG. No. C-100 of the Site Plan package for more information.

As part of the site design, the project area was further raised in elevation to provide greater separation from the adjacent floodplain area. Site fill and on-site excavated material will be utilized to raise the site elevation a minimum of one foot to 273 feet, with most of the Site located above 274 feet. As such, a minimum of 3-feet separation from the 1% chance floodplain elevation is achieved on the Subject Site, and the BESS equipment is located entirely outside the floodplain.

Benefits to the Town of Greenburgh and Village of Elmsford

The Battery Energy Storage System (BESS) that will be installed on the Knollwood Country Club site will incorporate 28 pre-manufactured “cabinet” megapacks on a concrete foundation and provide 80 MW of stored energy via reliable on demand power every day of the year for peak needs and renewable integration. The system will help to minimize power outages in Elmsford and Greenburgh, as well as across Westchester County. The BESS will help facilitate the phasing out of gas fired powerplants that can contribute to climate change and which have the potential to cause air pollution and smog. The BESS will also assist with maintaining the level of electric power as the Indian Point Nuclear Powerplant goes off-line in 2021. Once on line, the BESS will join dozens of other communities across the United States that are utilizing advanced battery storage facilities to provide on-demand and reliable electricity.
