Transformer explodes and fire damages vehicles in Port Hope

What happened

On the night of Wednesday 7 May 2025, shortly after 10 p.m., Port Hope Fire and Emergency Services responded to several 911 calls reporting an explosion at the Esco property on Hope Street South, Port Hope. Firefighters found that a 44,000-volt transformer at the site had exploded and that the fire had spread to several vehicles parked below it. Crews extinguished the blaze without further incident. The failure of the transformer caused a power outage across a large part of the municipality. Elexicon Energy attended the location, and repairs and a damage assessment were under way at the time of reporting. No injuries were reported.

Contributing factors

Not reported. The source does not state the cause of the transformer failure.

Lessons learned

1. Review separation distances between high-voltage transformers and parked vehicles, public areas and buildings, and keep exposed areas clear where practicable.
2. Fire services should hold pre-incident plans for transformer sites that identify exposures such as nearby vehicles and outage impacts.
3. Utilities should have rapid isolation and damage assessment procedures to limit the area affected by an outage and shorten repair times.
