What happened

On a Sunday evening, a fire occurred at a Georgia Power substation in the Stockbridge area of Henry County, Georgia, at the intersection of GA-138 and Rock Quarry Road. Henry County Fire and Rescue were fighting the fire. Georgia Power said the fire initially affected service to about 10,000 customers, including Piedmont Henry Hospital in Stockbridge, which used backup power to continue services. The company said it was working to reroute power and restore service. It later reported that all customers had power restored. A cause was not known at the time of the report.

Contributing factors

A cause was not known at the time of the report.

Lessons learned

  1. A substation fire can interrupt supply to a large number of customers at once, so operators should be ready to reroute power and restore service quickly.
  2. Hospitals and other critical sites may lose grid supply during a substation fire and need working backup power.
  3. Where the cause is not yet known, operators should preserve evidence and complete an investigation before drawing conclusions.
