5 fires in 5 years! The former world’s largest lithium battery ESS power station is on fire again!
Vistra Energy's Moss Landing energy storage power station in California experienced its fifth fire in five years on September 18, 2026. The station, once the world's largest with a capacity of 750MW/3000MWh, has faced repeated fires since 2021, leading to significant damage and a $400 million write-off. Vistra Energy is evaluating the restart of Phase III, while Phases I and II remain offline. The fires have raised concerns about energy storage safety and community resistance to such projects.
