Duke Energy restored electricity to a large area of southwestern Wilkes County and a small section of western Wilkesboro about 10:40 a.m. Wednesday.
Duke Energy spokesman Meghan Miles said the outage resulted from a transformer bank in the substation on Old N.C. failing. Miles said electricity was restored by switching to a different transformer bank at the same substation.
She explained that transfer banks are part of the equipment used to reduce voltage at a substation so electricity can be passed on to individual customers.
Over 3,600 Duke Energy customers in southwestern Wilkes and part of western Wilkesboro lost electricity about 9 a.m. Wednesday.
The Duke Energy outage map showed the outage fanning out westward from a point where the company has a power station along Old N.C. 268 just west of Blue Ridge Tractor, plus a small area to the east that includes part of western Wilkesboro.
The map showed the outage going westward on U.S. 421 to just east of the Fall Creek Road intersection at the base of the Blue Ridge Mountain escarpment, to the Wilkes-Caldwell county line on N.C. 18 South and to the Wilkes-Caldwell county line on N.C. 268 West.
