East Side residents experienced a blackout Thursday night.
Penn Power area manager Bart Spagnola said about 350 residents suffered through an extended blackout after an equipment failure at the Shenango substation, located on Vogan Street and Huron Avenue.
"This is a big station, Spagnola said. "One of three phases went down about 6 p.m. We found the source of the problem by 9:15 p.m. and realized that we had to shut down the other two phases in order to correct it."
This was necessary, Spagnola said because, "our crew can't work on hot wires."
He estimates that approximately 1,000 customers were without power for about an hour.
"Our records show that power was restored to everyone by 10:15 p.m." he said.
This outage, he said, had no connection to the work being done in that area by Verizon crews.
"The power outage was an overhead line," he said. "I hope this is the only outage we see this Christmas season."
