Power has been restored to the more than 12,000 customers who were without power in five East Texas counties Tuesday.

The majority of affected customers were in Wood County, with others in Hopkins, Rains, Smith and Titus counties.

Paige Eaton, spokeswoman with the Wood County Electric Cooperative, said AEP SWEPCO, a transmission provider for the cooperative, had a transformer catch fire at its Quitman substation.

That severed the transmission feed, causing an outage to seven of its substations that feed over 11,700 meters in the five counties.

The cooperative and AEP SWEPCO worked to restore power to all but 600 meters by 4:30 p.m. Tuesday. By 8:30 p.m. Tuesday, power was fully restored.

Because of the heavy load, sections were brought online one at a time.
