In Short : Using 500 used electric vehicle (EV) battery packs to build a 24 MWh grid-scale energy system in Bexar County, close to San Antonio, B2U Storage Solutions, a California-based company, is making history by building its first energy storage facility in Texas. This invention promotes renewable energy, aids in the energy transition, and strengthens decarbonization initiatives.
Project Highlights & Technical Approach
Battery System: To avoid expensive battery rebuilding, the project repurposes 500 discarded EV battery packs into 21 modular cabinet units that are outfitted with plug-and-play technology (Electric Pack Storage, EPS) certified by UL-9540.
Capacity and Deployment: The Bexar Corrilla site has a total energy storage capacity of 24 MWh.
After 40 MWh of second-life storage was already installed in California, a significant grid-connected deployment was made.
Market Context: By mid-2026, B2U’s Texas portfolio will have grown to around 150 MWh, with three more projects totaling 100 MWh.
Without the need for additional transmission infrastructure, these systems can assist stabilize the grid in Texas’s erratic wholesale power market by storing extra renewable energy during periods of low demand and dispatching it during times of high demand.
The Importance of Clean Energy and Sustainability
Extending Battery Life:
The project shows energy efficiency, lowers e-waste, and promotes the green economy through strategic repurposing by giving EV batteries a second life beyond their automotive use.
Grid Resilience & Renewable Integration:
By enhancing renewable energy systems, these BESS installations make it possible for energy storage to support sporadic solar and wind power supplies, which is essential for reaching net zero emissions.
Data from the ERCOT region of Texas indicates that batteries were crucial in averting blackout situations, highlighting the significance of these storage additions.
The Significance of It
This project demonstrates how, without the need to produce new hardware, used EV batteries may be a key component of energy storage for renewable energy systems. Grid efficiency and environmental stewardship are made possible by B2U’s Texas initiatives, which are scalable and reasonably priced energy transition models. These storage options provide a calculated path for a fair transition and the creation of a clean-tech workforce as EV use rises.
