Do you support using repurposed electric vehicle batteries to help provide energy for your local grid?
B2U Storage Solutions has officially started commercial operations at the Bexar Martinez facility in Texas, contributing 28 MWh of energy storage capacity to the local grid. The project utilizes repurposed electric vehicle batteries to support reliability for homes and businesses within the CPS Energy service territory.
Why it matters
By giving second-life batteries a new purpose, this project helps lower energy storage costs and reduces battery waste while strengthening grid reliability in a fast-growing region. This development supports the broader transition toward more efficient and sustainable grid management.
The Bexar Martinez facility provides 28 MWh of grid services, joining a wider B2U portfolio in ERCOT that has now exceeded 50 MWh of total capacity. The company manages more than 5,000 repurposed electric vehicle batteries across Texas and California.
The players
B2U Storage Solutions
A developer that specializes in repurposing used electric vehicle batteries into stationary energy storage systems.
CPS Energy
The local utility provider serving the region where the new energy storage facility is located.
B2U Infrastructure Partners
The investment entity that owns the Bexar Martinez project and manages its financing.
The details
The facility uses patented battery storage cabinets designed to house repurposed electric vehicle batteries that are no longer suitable for driving but remain effective for stationary grid storage. This infrastructure, owned by B2U Infrastructure Partners, qualified for the domestic content bonus under the Investment Tax Credit. The project provides critical grid services within the CPS Energy service territory to assist with localized power demand.
Timeline
Commercial operations at the Bexar Martinez facility began on September 26, 2026.
B2U plans to deploy an additional 50+ MWh of storage capacity within the next six months.
The Home Front
This project follows a growing trend of utilizing federal tax incentives to scale grid-level battery storage capacity. It aligns with the Inflation Reduction Act's domestic content bonus provisions intended to bolster local energy infrastructure.
Residents in the CPS Energy service territory may benefit from increased grid reliability as this new storage capacity comes online. Homeowners interested in the sustainability of their own energy use can track how local utilities incorporate grid-scale battery storage to stabilize power during peak demand periods.
The takeaway
This project highlights a practical shift toward reusing battery materials to stabilize the power grid in high-growth areas. Homeowners can observe these regional trends to better understand how local energy providers are preparing for increased demand on infrastructure.
What happens next
B2U anticipates the deployment of an additional 50+ MWh of storage capacity within ERCOT over the next six months.
