California Projects
-
SEPV Sierra
In operation since 2020, the SEPV Sierra project in Lancaster, California is an 8MW/32MWh hybrid energy storage system that charges from on-site solar and from the grid. Over 1,300 repurposed EV batteries are used in this energy storage system. The hybrid solar-plus-storage project provides power and grid services to the CAISO wholesale market.
-
SEPV Cuyama
Commissioned at the end of 2023, the SEPV Cuyama project in Santa Barbara County, California is a 3MW/ 12MWh hybrid energy storage system that charges from on-site solar and from the grid. 600EV battery packs are deployed in this energy storage system. The project sells power and grid services into the California Independent System Operator (CAISO) wholesale market.
-
One Ten Partners
B2U is converting this 2.7 MW PV project into a hybrid facility in 2024. The project is located in Palmdale, California and was developed and commissioned in 2017 by B2U’s predecessor company, Solar Electric Solutions. Once the conversion is complete, the hybrid system will have 10 MWh or storage capacity.
Texas Projects
-
Bexar Corrilla
In operation since 2025, the Bexar Corrilla project in Bexar County, Texas is a 24 MWh /10.0 MW energy storage system providing capacity for ERCOT. Over 720 repurposed EV batteries are used in this energy storage system and the project continues to expand.
-
Bexar Martinez
We broke ground on the “Texas 10” project in April 2026. This 24 MWh / 10 MW project is in Bexar County, Texas and will provide grid services in ERCOT. Leveraging 700+ EV batteries in B2U’s innovative battery energy storage system.
