Clay Energy Storage 1 is a proposed 250 MW battery energy storage development project in Onondaga County, New York. The project is being developed by Terra-Gen Development Company, LLC, and is classified as a standalone storage project using energy storage (ES) technology. It is proposed to interconnect to the transmission system at the Clay 345 kV Substation, in the service territory of transmission owner NM-NG.
The project is listed in the New York Independent System Operator (NYISO) interconnection queue under queue ID NYISO-C26-0022, with a queue entry date of August 13, 2026. Its status in the queue is active. The available queue data does not include a proposed commercial operation date or the status of an interconnection agreement.
