The Trelina Energy Storage project is a proposed 120 MW battery storage project located in Seneca County, New York. It is being developed by NextEra Energy Resources Interconnection Holdings, LLC and is interconnected to the New York State Electric and Gas (NYSEG) utility. The project entered the New York Independent System Operator (NYISO) interconnection queue as queue ID NYISO-C24-207 on September 19, 2024, with a proposed commercial operation date of December 1, 2029.
The point of interconnection (POI) is the Planned Q720 Trelina Solar Switchyard on the Border City to Station 168 115 kV line. The project is currently listed as active in the NYISO interconnection queue. Recent news coverage has discussed the development.
