The New York State Public Service Commission on April 20 said that it will hold a virtual public statement hearing on April 27 concerning East River ESS, LLC’s February petition seeking a certificate of public convenience and necessity (CPCN) for a stand-alone, battery based energy storage facility.
As noted in a full environmental assessment form and narrative filed with the commission on April 16, the facility would be built on the site of the New York Power Authority’s (NYPA) former Charles Poletti Power Plant and interconnect to a Con Edison 138-kV substation adjacent to the project site. The project would consist of a 100-MW battery storage system with 400 MWh of storage capacity.
The form also noted that East River ESS is also petitioning the commission for an order providing for financial approval and lightened regulation.
The project would be composed of metal cabinets — identified as megapacks — about 10 feet wide by 8 feet high and 24 feet long, housing racks of battery modules. The form added that the project also includes a control house and an interconnecting generation tie line (gen-tie). The megapacks would be placed on four elevated platforms, each about 18,000 square feet of steel grate. The form also noted that the batteries feed into power inverters, which convert the power from direct current (DC) to alternating current (AC).
The power coming from the inverters is collected at a project substation — to be developed, owned, and operated by East River ESS — which, in turn, is stepped up to transmission-level voltage, where it then feeds into the Con Edison 138-kV Astoria-West switchyard located immediately east of the project site and serving as the point of interconnection to the transmission grid. The form added that the gen-tie would be about 150 to 650 feet long, depending on the final route, and that both underground and overhead options are under consideration.
Among other things, the form noted that the project would not require any water for operation other than that required to operate the fire suppression system in case of emergency.
In its statement, the commission said that the April 27 meeting may be accessed online at www.webex.com (Event Number: 129 839 4295, Password: April27-1pm), as well as telephonically at (518) 549-0500 (Access Code: 129 839 4295). Any person wishing to provide a public statement on the record at the hearing must pre-register to do so by 3 p.m., on April 26, the commission said.
