SAN DIEGO (FOX 5/KUSI) -- A battery storage project at Marine Corps Base Camp Pendleton is receiving a $42 million grant from the State of California. International Electric Power aims to enhance California's energy storage by providing electricity to the statewide grid and backup power to the base for up to 14 days in the event of power outages, state officials said in a news release Wednesday. “Since the beginning of my administration, California has been on the front lines of the global battery revolution. We’ve ramped up battery storage capacity by more than 1,600% - bringing us a quarter of the way to meeting our projected need. Battery storage projects like this one at Camp Pendleton are vital to building a reliable and resilient electric grid in the face of climate extremes,” Governor Gavin Newsom said. The project will be installed at Camp Pendleton’s Haybarn Energy Reliability Center, where it will provide 6 megawatts (MW)/48 megawatt hours (MWh) of long-duration energy storage, according to the state. The system could also be expanded to a 50 MW/400 MWh installation. Camp Pendleton, one of the Department of Defense's busiest installations, supports more than 70,000 military and civilian personnel and their families. The project is set to be operational in summer 2027.
