Repurposed EV batteries now delivering 28 MWh of grid services to ERCOT

B2U now operates 50 MWh of repurposed battery storage in Texas and roughly 100 MWh across Texas and California, using more than 5,000 second-life EV batteries. The company says Bexar Martinez supports reliability in one of ERCOT’s fastest-growing regions and expects to deploy more than 50 MWh of additional capacity in the market over the next six months. The project is commercially relevant because it shows second-life batteries qualifying for domestic-content incentives, third-party financing and acquisition by infrastructure investors.
