On January 21, Vistra announced its principal investigation findings and corrective actions related to the Sept. 4 incident that caused limited battery damage at its Phase I (300 megawatts/1,200 megawatt-hours) Moss Landing Energy Storage Facility in Monterey Bay, California. The investigation found that in response to detection of very low levels of smoke in one area of the facility, the water-based heat suppression system armed and, because of failures of a small number of couplings on flexible hoses and pipes, improperly sprayed water on battery racks.
