Summary

A fire broke out on September 22, 2026, in a lithium-ion battery storage unit at a Metropolitan Water District facility in La Verne, California, forcing the evacuation of approximately 500 homes. The fire spread to an adjacent battery unit, triggering thermal runaway. Emergency crews used cooling measures to stabilize temperatures in the affected units while monitoring for heat exposure and potential reignition. Air quality monitoring detected no hazardous materials in the smoke or atmosphere. Lithium-ion battery specialists arrived to assist with extraction of the damaged units, which were removed to a hazardous waste facility. Evacuation orders were lifted on Friday, September 26, at 6 a.m., after the affected battery modules were removed. The water supply remained unaffected throughout the incident. The cause of the fire remains under investigation. The facility's two undamaged battery units on the south side were scheduled to be powered down and removed.
