B2U Storage Solutions, a provider of large-scale repurposed battery energy storage systems, has started construction on its third grid storage facility and first in the state of Texas.
The facility is located in Bexar County, east of San Antonio, and will have a total capacity of 24MWh. It is expected to be fully operational and transacting with the Texas grid later this year.
B2U will deploy approximately 500 EV battery packs that have reached automotive end-of-life across 21 cabinets.
The Bexar Corrilla facility will interconnect to the CPS Energy distribution system.
B2U has previously deployed over 40 MWh into the California grid. The company’s patented EPS technology is certified to UL 9540 and enables plug-and-play deployment of EV batteries while avoiding remanufacturing costs, it said.
B2U’s BESS platform “provides safe and reliable operation 24/7, and leverages AI to optimally bid and deliver power and grid services into wholesale markets,” it said.
Over the next 12 months, B2U plans to deploy three additional grid storage projects using repurposed EV batteries in Texas, for a total deployment of 100 MWh in the state.
Including its California solar plus storage projects, B2U plans to have deployed over 150 MWh of repurposed EV batteries by mid-2026.
A December 2024 report from IDTechEx forecasts that through 2035, over 200 GWh of global demand for grid storage could be supplied by repurposed EV battery packs, the company noted.
“With tens of millions of EVs expected to reach automotive end-of-life over that timeframe, B2U’s EPS technology platform will be critical for maximizing the resource and economic utility of EV packs prior to recycling.”
