EIR-1310

Provisional entry. Published from first reports. This entry is rechecked automatically and updated when more sources appear. Next update: 27 September 2026.

Gwinnett County Fire Rescue responded early on a Tuesday to a fire at a high-voltage substation in Gwinnett County, Georgia. Crews found a transformer on fire, with a large fire and heavy heat inside the substation perimeter. They set a protective perimeter and called Georgia Power to help with electrical hazards. The Hazardous Materials Team and the Georgia Environmental Protection Division monitored for possible environmental hazards. The fire was brought under control around 6:30 a.m. No injuries and no significant power outages were reported. Georgia Power staff were investigating the cause and making repairs.

The cause was not reported. Georgia Power was still working to determine it.

  1. Substation fires need an early plan with the network operator to manage electrical hazards before crews work inside the perimeter.
  2. Environmental monitoring should be mobilised where a transformer fire may release oil or other materials.
  3. Cause investigation and repairs should wait until the fire is controlled and electrical hazards are mitigated.
