Marcy BESS is a proposed battery energy storage development project in Oneida County, New York. Developed by RWE Solar Development, LLC, the project has a total proposed capacity of 199.9 MW and is classified as a standalone storage facility using energy storage (ES) technology. It is planned to connect to the grid at the Marcy T1 345 kV point of interconnection, with the New York Power Authority (NYPA) identified as the transmission owner.
The project is listed in the New York Independent System Operator (NYISO) interconnection queue under queue ID NYISO-C26-0038, with a queue entry date of August 27, 2026. As of the latest available data, its interconnection request has an active status. The provided records do not include a proposed commercial operation date or the status of an interconnection agreement.
