What happened
A fire broke out in the early hours at a battery storage unit forming part of the Summerside Sunbank solar power farm, a municipal solar facility owned and operated by the City of Summerside in Summerside, Prince Edward Island, Canada. Emergency services contained the fire to a single battery unit within a multi-unit storage system rated up to five megawatts. Authorities issued a shelter-in-place order for nearby residents and a voluntary evacuation within a 500 metre radius, citing concerns over smoke and steam potentially carrying toxins, which were exacerbated by recent heavy rainfall and firefighting water application to the site.
A reception centre was opened for displaced residents. Fire crews used thermal drones to monitor hotspots and maintained a rotating on-site presence for over a day. Because battery fires cannot be extinguished with direct water application, crews allowed the affected unit to burn out while monitoring for spread. The fire did not spread to adjacent batteries or electrical infrastructure, and no interruption to grid power supply was expected.
Contributing factors
Recent heavy rainfall combined with firefighting water application increased ambient smoke and steam, prompting a precautionary shelter-in-place order; root cause of the battery fire itself was not reported.
Lessons learned
- Battery storage fires cannot be put out with water, so crews must let the unit burn out while monitoring for spread to other modules.
- Shelter-in-place orders around battery sites must allow for smoke and steam hazards made worse by rain and firefighting water.
- Early containment at battery farms can stop fire moving from one unit to adjacent batteries or electrical systems.
