Columbia Generating Station

Columbia Generating Station nuclear facility is the third largest electricity generator in Washington, behind Grand Coulee and Chief Joseph dams. Its 1,207 gross megawatts can power a city the size of Seattle, and is equivalent to about 10 percent of the electricity generated in Washington and 4 percent of all electricity in the Pacific Northwest.

Columbia is the only commercial nuclear energy facility in the region. All of its output is provided to the Bonneville Power Administration at the cost of production under a formal net billing agreement in which BPA pays the costs of maintaining and operating the facility.

Columbia began delivering power to the region in 1984. Since then it has provided billions of dollars worth of electricity while emitting virtually no greenhouse gases or carbon emissions commonly associated with natural gas, coal and other fossil fuel powered plants.

Benefits to the Region

Nuclear power is a reliable energy producer. Columbia is not dependent on weather conditions as are hydro, wind and solar generation facilities. Nuclear plants produce electricity 24-hours a day, seven days a week.  

Refueling and maintenance outages occur every other year and are scheduled when springtime water conditions in the Columbia River Basin are typically high, allowing the federal hydropower dams to produce ample supplies of power.​ 

Status of U.S. Nuclear Power

Nearly 20 percent of our nation’s electricity comes from 99 currently operating nuclear facilities throughout the United States.

The nationwide push for carbon-free electricity and federal and private investment in the development of small modular reactors have resulted in further consideration of nuclear power as a generation resource. Small modular reactors are factory fabricated nuclear generators, built and installed according to standardized designs.

Type:
Boiling water reactor (nuclear)


Generation:
 
1,207 megawatts (gross) 1,207 megawatts (gross)

Location:
10 miles north of Richland, Wash.
 
Site Size:
~ 1,089 acres

 

Projected Levelized
Cost of Power
(2014-2043):

4.7 - 5.2 cents/kWh

Comparison Costs*: 
Natural Gas: 6 - 14 cents/kWh
Wind: 7 - 10 cents/kWh
Solar: 11 - 42 cents/kWh 

*Levelized costs according to the Energy Information Administration. Levelized cost represents the per kilowatt-hour cost (in real dollars) of building and operating a generating plant over an assumed financial life and duty cycle. Key inputs to calculating levelized costs include overnight capital costs, fuel costs, fixed and variable operations and maintenance costs, financing costs and an assumed utilization rate for each plant type.
