Operators took Columbia Generating Station offline today at 4:05 p.m. following an issue with a valve connected to the plant’s steam condenser. The valve, located in the station’s turbine building, failed closed, causing a loss of vacuum necessary to pull steam through the condenser. The plant is stable, the valve has been re-opened and work is beginning to bring Columbia back online, to include maintenance on associated plant systems.

 “Following our refueling and maintenance outage the team has had Columbia running well, even setting a record for July generation,” said Bob Schuetz, plant general manager. “We expect to pick up where we left off after a thorough review of the valve and performing any maintenance that is required.”

Columbia Generating Station, with an output of more than 1,200 megawatts electric (gross), is the third largest generator of electricity in Washington state. All of its electricity is sold at-cost to the Bonneville Power Administration. Ninety-two Northwest utilities receive a percentage of its output.
