Texas project to turn 500 used EV batteries in grid power storage

B2U Storage Solutions, a California-based company, is developing a new battery storage facility in San Antonio, Texas, called the Bexar Corrilla project. This facility will repurpose approximately 500 used electric vehicle (EV) battery packs to create a 24 megawatt-hour (MWh) energy storage system capable of powering around 800 homes for a day. The project leverages B2U’s patented EV Pack Storage (EPS) system, which allows modular, plug-and-play integration of second-life EV batteries into the grid without the need for costly refurbishing. The system is certified safe (UL 9540) and uses artificial intelligence to optimize energy storage and trading based on real-time grid demand and pricing. Texas was chosen due to its isolated and fragile power grid, which increasingly relies on intermittent renewable energy sources like solar and wind. Battery storage is critical for grid stability when renewable generation fluctuates. This project marks B2U’s first facility in Texas and third overall,
