Citizens from Chickasha to Duncan were left in the dark last night, after a mechanical failure caused a power outage that initially affected more than 8,300 PSO customers.
The outage started at 12:29 a.m. and lasted until 3:17 a.m. for some, said Ed Bettinger, PSO spokesperson.
Bettinger said a crossarm on a transmission line supplying a substation east of Chickasha went down, resulting in the power failure.
"The equipment out there is very robust," Bettinger said. "They tend to stay in the elements for long periods of time and we just happened to have a mechanical failure."
Power came back on in sections, according to Berringer, with 2,942 customers in Duncan and Rush Springs having their electricity restored 11 minutes after the initial outage.
A group of 3,069 customers came back online at 1:38 a.m in an areas east of Chickasha, and power was restored to 2,400 customers in Blanchard at 3:17 a.m.
"These things happen sometimes," Berringer said. "The crossarm lets go and trouble ensues. Hopefully this will never happen again."
Berringer said crews spent Tuesday working on the substation.
