ESS Inc., a leading manufacturer of safe, low-cost and long-duration energy storage systems, announced that it has deployed an Energy Warehouse (EW) long-duration flow battery system at Marine Corps Base Camp Pendleton in San Diego, California. The 50 kW / 400 kWh battery is integrated into a microgrid with a CleanSpark microgrid controller, and provides up to eight hours of storage to enable back-up capabilities for critical loads; operational energy cost savings through on-site generation with storage; and full islanding capabilities for resilience. The project is being completed in partnership with the project's prime contractor, Bethel-Webcor JV.

"We are pleased to commission our second Energy Warehouse system in a military microgrid application," said Craig Evans, Founder and CEO of ESS Inc. "Camp Pendleton is the Marine Corps' largest West Coast expeditionary training facility for Marine, Army and Navy units. The Camp will especially benefit from our battery's solar-plus-storage capabilities, which enable the microgrid to store excess solar energy for later use during times of peak electricity demand."

"We are proud to partner with ESS Inc. for the Camp Pendleton project, as it marks the first-ever deployment of a solar-plus-storage system utilizing an iron flow battery," said Anthony Vastola, SVP of Projects for CleanSpark. "The solution operates in off-grid mode by default so as to maximize efficiency, utilize solar over-generation and extend the overall life of the system. As a whole, we expect the microgrid will provide energy and cost-savings, as well as improved energy security, to Camp Pendleton for years to come."
