Transformer fire cuts power to downtown Bangor apartment building during heat wave

A ground-mounted transformer at Gallagher Place in downtown Bangor, Maine, overheated and caught fire on 3 July 2026, during a heat wave with a heat index near 100 degrees Fahrenheit. The transformer sits on a concrete pad next to Bangor House Apartments, a six-storey building housing disabled and elderly residents, with wiring running underground into the building. Firefighters arrived to find smoke and explosions coming from the transformer cabinet. Residents were evacuated until Versant Power arrived to disconnect power. Some residents were later allowed back into the building, though without power. Others were taken by bus to a cooling centre at the Bangor Area Transit Center. The Red Cross was contacted, and officials warned the outage could be prolonged while replacement parts were sourced.

The transformer overheated, reportedly contributing to the electrical fire; the incident occurred during a heat wave, which increased urgency around the loss of power and cooling for vulnerable residents.

1. Distribution transformers serving buildings with vulnerable residents should be monitored for thermal stress during periods of extreme heat.
2. Emergency response plans for vulnerable-occupant buildings should include readily available cooling centres and transport in case of power loss during heat events.
3. Utilities should maintain accessible spare parts inventories to reduce restoration time for critical low-income or elderly housing after equipment failures.
