What happened
Two lithium-ion battery energy storage sites in Warwick, New York experienced separate incidents within about 24 hours of each other during a storm. A fire broke out at a storage site on County Route 1 that burned for several days, while a second site on Church Street Extension emitted fumes that worried nearby residents. Hazmat crews carried out around 20 hours of air metering over three days and reported no elevated levels of battery-related chemicals.
The school district also tested surfaces in buses and classrooms and found no harmful residue. Batteries at the Church Street site were packaged and removed for disposal, while the batteries at the County Route 1 site were left in place after cooling to assist investigation. Convergent Energy and Power, the integrator, and Powin, the battery manufacturer, said they had staff on site working with local fire officials to determine the cause.
Contributing factors
A large storm affected both sites around the time of the failures. Both sites used a newly deployed battery system model that had been in service for only a short period before the incident.
Lessons learned
- A newly deployed battery system model requires close monitoring in its first months, as both sites used one that had been in service only a short period.
- Storm events near new battery assets call for rapid response, as a large storm affected both sites around the time of the failures.
- Independent air and surface testing after a fume event helps confirm no spread, as hazmat crews found no elevated levels and school tests found no residue.
