US power producer Calpine Corporation expects to finalise the first three phases of its 680-MW battery energy storage project in Menifee, California, in the summer of 2024 and unveil the completed facility in 2025.
The Nova Power Bank battery energy storage system (BESS) will have the capacity to store 510 MW this summer, Calpine said on Thursday. The company will aim to complete the 110-MW fourth phase in autumn and wrap up the project with 60 MW in phase five in 2025.
Nova Power Bank’s batteries will be spread across 43 acres (17.4 ha) of land, repurposing a site of a decommissioned natural gas-fired power plant. Once powered up, the BESS will provide energy storage and discharge capabilities form utilities Southern California Edison, Peninsula Clean Energy, and San Diego Gas & Electric, Calpine said.
Calpine secured more than USD 1 billion (EUR 926.3m) in debt financing to pour into the project. Besides Nova Power Bank, the company has more than 2,000 MW of battery storage in development in California.
