RICHLAND, Wash. – Columbia Generating Station went off line at approximately 7:00 a.m. after the main power transformers automatically disconnected from the grid. The reactor was safely shut down and the cause of the disconnect is under investigation.

Columbia responded as designed and the plant is stable. All systems are operating as expected and there is no threat to public health or safety.

“We are working now to thoroughly understand the issues involved and look forward to returning to full-power,” said Dave Brown, plant general manager.

Columbia Generating Station, owned and operated by Energy Northwest, with 1,207 megawatts of gross capacity, is the third largest generator of electricity in Washington state. All of its electricity is sold at-cost to the Bonneville Power Administration, and 92 Northwest utilities receive a percentage of its output. The facility is located 10 miles north of Richland, Wash.
