What happened
On the evening of 23 September 2025, the Bosworth electrical substation in Ekurhuleni, South Africa, caught fire. Emergency services responded to a structural fire alarm and found an electrical panel house fully engulfed in flames, with part of the roof having already collapsed. Responding crews required backup due to the scale of the fire. An electrician was called to site to advise on safety before firefighters could begin suppression. Three attack lines were used to contain and extinguish the blaze, with defensive cooling applied to nearby transformers to protect them from fire exposure.
The fire caused widespread power outages affecting Alrode North, outside Alberton, and Thokoza township. It was reported that a power failure in the area was followed by a loud explosive sound from one of the transformers, after which flames were seen from the electrical panel building. Investigations into the cause were ongoing at the time of reporting.
Contributing factors
A power surge is alleged to have caused an explosive event in one of the transformers immediately after power was restored following an earlier outage, which is suspected to have triggered the fire in the adjacent electrical panel building.
Lessons learned
- Power restoration after an outage should include monitoring for surge conditions that could stress transformers and switchgear.
- Emergency responders at substation fires should coordinate with qualified electricians before suppression, given risks of live equipment.
- Protective cooling of adjacent transformers during a panel house fire can help prevent escalation and additional equipment loss.
