A tree branch knocked down power lines causing a building to catch fire on Route 64 in the Town of Bristol in Ontario County Friday morning.
Multiple crews arrived at the scene around 2:20 a.m. to battle the blaze at a vacant, metal-framed car dealership.
They were unable to put out the flames because the building was energized.
Crews demolished the building after the fire burned out.
No injuries were reported.
Power for about a three-mile stretch around the dealership will be out until RG&E repairs the damage.
"As soon as we got here we realized the building was energized with power and we established a safety zone around the building and kept everyone back 50 feet around the building until we have RG&E on the scene. We couldn't fight the fire until RG&E got here to render the power safe," said Bristol Fire Department Chief Eric Dey.
More than 1,000 homes are currently without power in Ontario County.
