Vistra announced that its Moss Landing Energy Storage Facility connected to the power grid and began operating on Dec. 11, 2020. At 300 megawatts/1,200 megawatt-hours, the lithium-ion battery storage system, located on-site at Vistra'sMoss Landing Power Plant in Monterey County, California. Furthermore, construction is already underway on Phase II, which will add an additional 100 MW/400 MWh to the facility by August 2021, bringing its total capacity to 400 MW/1,600 MWh. Housed inside the power plant's completely refurbished former turbine building and spanning the length of nearly three football fields, Phase I of the battery system can power approximately 225,000 homes during peak electricity pricing periods. The system is made up of more than 4,500 stacked battery racks or cabinets, each containing 22 individual battery modules, which capture excess electricity from the grid, largely during high solar-output hours, and can release the power when energy demand is at its and solar electricity is declining, usually early morning and late afternoon. Phases I and II of the Vistra Moss Landing Energy Storage Facility are backed up by long-term resource adequacy contracts with Pacific Gas and Electric Company (PG&E). Vistra'sMoss Landing site provides a unique opportunity for extensive future expansion of the battery storage system. With its existing infrastructure and the physical space for potential growth, this world-class industrial-zoned site can support up to 1,500 MW/6,000 MWh of storage capacity should market and economic conditions support it. With the development permit already in place and the site in condition for expansion, Vistra will be able to move quickly when that time comes. Vistra is a market leader in utility-scale battery energy storage development and commercialization. Its Moss Landing project is the of 4,000-MW zero-carbon Vistra Zero portfolio, which includes a total of five battery projects in California and Texas: Upton 2 (10 MW/42 MWh) – online December 2018; Moss Landing – Phase I (300 MW/1,200 MWh) – online December 2020; Moss Landing – Phase II (100 MW/400 MWh) – expected online by August 2021;Oakland (36.25 MW/145 MWh) – expected online 2022; AND DeCordova (260 MW/260 MWh) – expected online 2022.
