EMPORIA, Kan. (AP) — More than 3,700 Emporia-area residents were without power for a few hours early Tuesday but electricity has been restored.

Westar Energy officials have not confirmed a cause for the power outage but it occurred shortly after a fire damaged equipment at a substation.

KVOE reports Fire Capt. Ryan Schmidt says some flames were seen at the substation and at least one transformer caught fire.

Westar cut the power so the fire could be extinguished. No damage estimate was released.

The outages affected sections of Emporia, including Emporia State University, and towns in Lyon and Coffey counties. Most of the power was restored by 5 a.m. Tuesday.
