Power was shut down to all 2,100 residents of Olive Hill late Saturday and into Sunday morning as firefighters battled a blaze that destroyed two buildings.
The power had to be shut off because live power lines running in front of Parker's Bargain Center and an empty building were falling near firefighters, said Assistant Fire Chief Jeremy Rodgers.
Power was restored to most of Carter County city within two hours, Rodgers said.
No one was hurt, but the fire displaced five residents of three upstairs apartments. The Red Cross is assisting those residents.
The cause of the fire is still under investigation, Rodgers said. More than 70 firefighters from nine different departments worked to extinguish the blaze.
