B2U Storage Solutions has announced plans to build a new battery storage facility in San Antonio, Texas, leveraging recycled electric vehicle (EV) batteries for grid power storage. The Bexar Corrilla project will utilize around 500 reclaimed battery packs, capable of storing 24 megawatt-hours (MWh) of electricity, which could power approximately 800 homes for a day. This initiative aims to give old EV batteries a second life, ensuring they aren’t discarded while supporting the stability of Texas’s power grid.
The facility will be connected to CPS Energy, the local utility, and is designed to maximize the usable capacity of old EV batteries, which can still retain 70-80% of their efficiency. Instead of recycling or sending these batteries to landfills, B2U’s approach allows for them to be transformed into energy storage units through their patented EV Pack Storage (EPS) system. This modular system can integrate multiple battery packs from various EV brands and is engineered for easy deployment, eliminating the high costs associated with refurbishing used batteries.
B2U’s “plug-and-play” design allows for direct connection to the grid without extensive remanufacturing processes, adhering to safety standards (UL 9540). Moreover, the system employs artificial intelligence to optimize power trading, managing when to store or sell electricity based on real-time grid needs.
Texas was chosen as the project location due to its challenged power grid, which requires robust storage solutions, particularly given the increasing reliance on intermittent renewable energy sources like solar and wind. The Bexar Corrilla project marks B2U’s first facility in Texas and their third overall, with plans for further expansion in the state to reach 100 MWh of storage capacity by mid-2026. As electric vehicles proliferate, the importance of such projects will grow, promoting sustainable practices in handling end-of-life batteries while also enhancing grid reliability with no additional new batteries needed.
