A power outage in downtown Grass Valley Wednesday afternoon was caused by a transformer fire.
Grass Valley Fire received a call for smoke coming from an underground vault, said Division Chief Jerry Funk. Crews arrived to find a PG&E underground electrical vault with smoke showing. Firefighters remained at scene until PG&E crews were able shut off the power.
The fire was contained to a transformer, Funk said. The power outage in the downtown area was expected to last several hours while PG&E replaces the damaged equipment, along with traffic restrictions on South Auburn Street.
