B2U Storage Solutions Launches Second 'Second-Life' Battery Project in ERCOT
B2U Storage Solutions has launched its second repurposed electric vehicle (EV) battery energy storage project, the Bexar Martinez installation, near San Antonio. The 28-MWh facility is part of a growing portfolio that includes over 100 MWh of operational 'second-life' installations in Texas and California. These projects use retired EV batteries to provide grid services at lower costs than traditional battery energy storage systems (BESS). B2U CEO Freeman Hall noted the company has secured significant volumes for repurposing, with supply expected to grow into many gigawatt-hours annually. The project is part of a broader 'Texas 10' initiative in ERCOT that could see several more installations begin construction soon and provide grid services by 2027. B2U expects to deploy over 50 MWh in ERCOT within the next six months, with its total pipeline exceeding 1,000 MWh across multiple markets. The company has also signed a supply agreement with Waymo for repurposing batteries from autonomous vehicles, which could provide hundreds of megawatts of storage capacity. B2U's installations benefit from lower degradation rates in real-world EV battery use than previously estimated, improving long-term viability and performance. These projects are eligible for tax incentives like the Section 48(e) investment credit bonus adder due to their domestic content.
