Project entered ERCOT interconnection queue at Facility Study stage
The Brazos Bend Storage SLF project is a proposed 243 MW hybrid battery storage project located in Milam County, Texas. Developed by Grenergy USA, the project consists of battery energy storage and other unspecified technologies. It is currently active in the ERCOT interconnection queue as entry ERCOT-29INR0164, with a queue entry date of September 11, 2025, and a proposed commercial operation date of September 17, 2029.
The project's point of interconnection (POI) is on the 345 kV Line (3765) GRISTMILL_5 to (39950) TNTNP_ONE_3. The project has appeared in recent news coverage regarding energy storage development in Texas.
