Seven Flags Battery Energy Storage is a 100 MW battery storage project being constructed in Webb County, Texas. The project will connect to existing infrastructure at the Wormser Substation, which is directly south of the project site. The energy will serve Electric Reliability Council of Texas (ERCOT) customers. 

 

The project is being constructed on roughly 10 acres of privately owned land and is close to existing electric infrastructure, so it will have minimal impact on area residents. Battery Energy Storage Systems use equipment that is approximately 10-12 feet tall, are fully contained, and do not require water or other public services.
