No workers injured in fire at 955.6-MW Priest Rapids hydro project in Washington State

A fire broke out yesterday at 3:15 pm in the exciter cabinet of the No. 1 generating unit at the 955.6-MW Priest Rapids hydro project, but no injuries were reported.

Grant County PUD reported on its Facebook page that 50 to 60 employees were evacuated from the facility and all were accounted for.

Employees at the scene called the Grant County fire department but were able to use the unit’s CO2 fire extinguishing system to put out the fire by 3:30 pm, before county firefighters arrived. Employees also began a process to clear smoke from the powerhouse.

The unit is currently out of service and the cause of the fire is under investigation. None of the other 10 generating units in the powerhouse were affected.

The Priest Rapids Dam and hydro project is on the Columbia River in Washington State. It was completed in 1956.
