US power producer and retailer Vistra (NYSE:VST) has powered up the expansion of its Moss Landing battery storage system in California, bringing its capacity to 750 MW/3,000 MWh.
The 350-MW/1,400-MWh Phase III was brought online in June and is now storing and releasing power to California’s grid, Vistra said on Tuesday. The additional capacity comes from 122 individual containers housing more than 110,000 battery modules. It will be run under a 15-year resource adequacy agreement with Pacific Gas and Electric Company (PG&E), which entered into force on August 1.
Co-located on the site of Vistra's existing natural gas-fueled Moss Landing power plant, the expanded Moss Landing battery in Monterey County is touted as the largest battery complex globally. Its Phase III was delivered within budget and on schedule, in 16 months.
"Continued investment in energy storage, like our Moss Landing site, allows us to harness and store a substantial and growing amount of power from intermittent renewables and then deliver that electricity when customers need it most,” said Jim Burke, Vistra’s president and CEO.
Vistra owns 37 GW of power assets, including natural gas, nuclear, coal, solar and energy storage capacity.
