Big Elm Storage is a proposed 100.8 MW battery storage project located in Bell County, Texas. The project, developed by Big Elm Storage, LLC, consists entirely of battery storage. It is listed in the ERCOT interconnection queue as entry ERCOT-23INR0469, with a queue entry date of April 18, 2022, and a proposed commercial operation date of November 10, 2027.
The project has an executed Interconnection Agreement (IA) as of May 10, 2024. Its point of interconnection (POI) is Tap 345 kV 3414 Temple Switch - 3409 Lake Creek. This proposed project is linked to the existing, operating Big Elm Storage facility (EIA plant ID 68181). The Big Elm Storage project has been mentioned in recent news coverage.
