What happened
On Monday evening at the Terra-Gen Energy Storage System in Valley Center, the emergency management system detected a smoke alarm in one battery storage unit. The Valley Center Fire Department and the San Diego County Hazardous Materials Division responded and remained on site monitoring the situation until 8:00 P.M. The facility safety systems contained the event to a small amount of smoke within a single unit and suppressed the fire. Terra-Gen personnel attended and coordinated with responding agencies. No threat to the public arose and no evacuation orders were issued. The incident was reported by local news with a drone image of the site.
Lessons learned
- Automated monitoring systems can provide early indication of thermal events.
- Unit-level containment design can limit smoke and fire spread.
- Coordination between operators and local fire and hazardous materials teams supports rapid monitoring and closure of incidents.
