BESS / StorageSep 18, 2026

Roughly 1,200 inaccessible, still-energized modules in the Moss 300 building ignited on Sept 18 during EPA-overseen cleanup of the Jan 2025 fire, triggering a shelter-in-place and underscoring that decommissioning risk does not end when the plant is offline. Underwriters and risk managers should treat post-loss battery removal, structural access, and reignition monitoring as first-class loss-control and BI exposures, not afterthoughts to the original fire. | Source: https://calmatters.org/environment/2026/09/moss-landing-battery-fire-reignites-fears/
