The Rockefeller Storage project is a proposed 206.8 MW battery energy storage system in Schleicher County, Texas. Developed by Mittel Rockefeller Storage LLC, the project is interconnected within the ERCOT region under queue ID ERCOT-22INR0239. The project entered the interconnection queue on October 31, 2019, and has a proposed commercial operation date of June 1, 2027.
The project's Interconnection Agreement (IA) was executed on September 23, 2024. The point of interconnection (POI) is the 76003 Big Hill 345kV substation. The Rockefeller Storage project has appeared in recent news coverage.
