The Antelope Valley Battery Energy Storage System (BESS), a 126 megawatt (MW) / 504 megawatt-hour (MWh) stand-alone battery system in Kern County, California, is now fully operating, according to a statement released today by Leeward Renewable Energy (LRE). As LRE’s eighth renewable energy project to go online in the state and its first grid-connected, standalone battery project, Antelope Valley BESS marks a significant turning point in the company’s energy storage strategy.
Powin’s four-hour Lithium Iron Phosphate (LFP) batteries power Antelope Valley BESS, which is intended to assist California’s electrical system by storing energy during periods of low demand and releasing it during periods of high demand. This feature increases total energy flexibility, balances out carbon-intensive generation, and strengthens system resilience.
“Bringing the Antelope Valley BESS facility online is a major milestone for LRE and reflects our commitment to accelerating energy innovation in California,” stated Sam Mangrum, EVP Project Execution at LRE. “As our first stand-alone battery project, it expands our capabilities to deliver dispatchable power when and where it is needed most. We are proud to support the broader energy market as California transitions to a cleaner, more resilient grid that can meet growing demand.”
In addition to creating around 90 employment during construction, the project is anticipated to generate long-term economic benefits for Kern County through community investments and local tax revenues, including a projected $30 million in property taxes throughout the facility’s lifespan.
It is LRE’s eighth active project in California, adding to a growing portfolio that already offsets over 30,228 metric tons of carbon dioxide equivalent emissions yearly and produces enough clean electricity to power over 28,000 households.
As part of its continuous dedication to community collaboration, LRE has contributed to local projects by supporting the Kern County Sheriff’s Mounted Posse, a nonprofit organization devoted to community service, and Rosamond Hills Senior Apartments, which houses low-income seniors.
“Our mission goes beyond clean energy—we strive to leave a lasting, positive impact in the communities where we operate,” attached Sam Mangrum. “Antelope Valley BESS not only strengthens California’s grid but also supports economic growth and resilience in Kern County.”
LRE continues to expand its national portfolio of utility-scale wind, solar, and battery storage projects, with more than 4 GW currently operating.
