510MW phase one of the Nova Power Bank will be complete this summer, with another 110MW coming online in autumn and the final 60MW in 2025
43-acre project is on the former site of Calpine’s Inland Empire legacy power plant, which it decommissioned in late 2022
didn’t reveal the capacity of the project but said that it could power 680,000 homes for four hours, implying it has a 4-hour duration, as the vast majority of California projects do. That would make it 2,720MWh
slightly smaller than the two largest operational BESS projects in the world, Moss Landing (3,000MWh) and Edwards & Sanborn (3,272MWh)
