The Ross Storage project is a proposed 510.99 MW battery storage project located in Refugio County, Texas. Developed by S&S Renewables, LLC, the project consists entirely of battery storage. It is currently active in the ERCOT interconnection queue as entry ERCOT-26INR0156, with a queue entry date of August 14, 2023, and a proposed commercial operation date of July 31, 2027.
The project's interconnection agreement has been executed as of June 27, 2024. The point of interconnection is planned at the 345 kV Angstrom (#8249) _x0013_ Static (#8676) line, managed by AEP. The Ross Storage project has been the subject of recent news coverage.
