World’s Largest Utility-Scale Battery Energy Storage System now Online
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 highest and solar electricity is declining, usually early morning and late afternoon. For further information see the IDTechEx report on Batteries for Stationary Energy Storage 2021-2031.
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).
“We appreciate the strong working relationship we’ve developed with PG&E on multiple projects and look forward to continuing to help meet its resource adequacy requirements and provide clean, reliable, and affordable power to Californians,” Morgan said.
Vistra’s Moss 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.
