What happened

A short report said firefighters contained a transformer fire at a Georgia Power high-voltage substation in Norcross, Georgia, early on 22 September 2026, after crews responded at 12:58 a.m. They encountered intense heat and a large fire inside the substation perimeter and set up a protective area while Georgia Power personnel managed electrical hazards. A hazardous materials team and the Georgia Environmental Protection Division monitored the area for possible environmental exposure.

The fire was reported under control by 6:32 a.m. No injuries were reported. The report said more than 13,000 people in the area were left without power. The cause had not been determined, and Georgia Power was reported to have taken over the site to investigate and begin repairs.

Contributing factors

The cause had not been determined at the time of the report.

Lessons learned

  1. A substation transformer fire can produce intense heat inside the perimeter, so crews should set a protective area before electrical hazards are managed.
  2. Where environmental exposure cannot be ruled out, hazardous materials and environmental agencies should monitor the site while the fire is controlled.
  3. Cause investigation and repairs can start once the operator takes the site back, and outage planning should not wait on a confirmed cause.
