Moss Landing Power Plant

Shelter-in-place lifted and roads reopened around Moss Landing facility

The fire flared up within energized battery modules inside the damaged Moss 300 facility in Moss Landing. Responders allowed the smoldering materials to burn out within a secure perimeter, and emergency operations concluded with no active fire spreading or visible smoke. The incident poses no threat to surrounding communities or property.

Evacuations and Closures

• All shelter-in-place orders for nearby residents and surrounding zones were lifted on September 19.
• Highway 1 and Dolan Road reopened to regular traffic on September 18, and all perimeter road closures have been lifted.

Impact

No injuries were reported among facility staff, emergency responders, or the public as of September 19. Air monitoring confirmed no hazardous levels of particulate matter or airborne chemicals in nearby communities, and the adjacent natural gas power plant has resumed normal operations.

Conditions and Outlook

Weather across the coastal area remains overcast and foggy with light southwesterly breezes and no rain expected over the coming days. On-site teams and environmental regulators are maintaining continuous monitoring to guard against flare-ups while conducting controlled demolition to safely remove remaining battery modules.

Cause and Context

The incident was caused by spontaneous ignition among energized battery modules that remained charged and inaccessible along the north wall of the facility. Firefighters managed the blaze by maintaining a secure perimeter and allowing the batteries to burn out rather than applying water due to reactivity risks.
