Vistra has completed its Phase III expansion project at its Moss Landing Energy Storage Facility in Monterey County, California. The project added 122 individual containers that together house more than 110,000 battery modules, increasing the site’s total capacity by 1,400 MWh.
The site is now successfully storing and releasing power to California’s grid, and on August 1st, it will begin operating under a 15-year resource adequacy agreement with Pacific Gas and Electric Company.
"As we navigate this energy transition to cleaner fuel sources, the ability to balance that shift with both reliability and affordability is paramount," said Jim Burke, Vistra president and CEO. "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."
This project serves as a continuation of Vistra’s commitment to sustainability, and its completion follows the recent announcement that the company will also expand its zero-carbon portfolio through the acquisition of Energy Harbor’s 4,000 MW nuclear fleet.
