Welcome to ColumbiaValue.com

Columbia Generating Station has never run better in its 31 year history. The key to that success is our people. Our Maintenance department, Operations, our engineers and many, many others who work hard every day to help the organization achieve and sustain excellence. It has truly been a team effort.


- Mark Reddemann, CEO


Columbia Generating Station produces enough electricity to power a city the size of Seattle. And the electricity from Columbia is carbon-free.

This reliable, around the clock power – not hindered by weather or time of day – has real future benefits when compared with alternatives.

Columbia Generating Station provides other benefits to the Northwest beyond providing reliable, affordable electric power. Columbia employs hundreds of dedicated, highly educated employees who live in the region and participate in the economy – it’s estimated that Energy Northwest generates nearly $500 million in economic activity right in the Mid-Columbia.

In addition to direct employment, Energy Northwest pays a “privilege tax” for being able to generate power ($4.5 million per year) and itself directly spends over $10 million per year with local businesses for a variety of goods and services.

Columbia Generating Station is an integral part of the community in more ways than one.

Did you know: more than 60 percent of the carbon-free electricity produced in the United States comes from nuclear energy? Yet nuclear energy receives little recognition for this clean air contribution.
For many states, such as Illinois, New York and New Jersey, nuclear energy is the largest source of carbon-free electricity.
In Washington state, Columbia Generating Station is the third largest electricity generator behind Grand Coulee and Chief Joseph dams. The carbon-free nuclear energy from Columbia complements the electricity produced by the Federal hydro-electric system and renewables to make Washington state’s electricity mix one of the cleanest in the nation.

According to a 2014 study by IHS Cambridge Energy Research Associates, Boston, Mass., Columbia prevents 3.6 million metric tons of carbon dioxide emissions annually compared to the most feasible replacement option of efficient natural gas-fired generation. That means Columbia has the carbon-saving equivalent of keeping 600,000 cars off the road annually.


“At present, it’s not possible to entirely eliminate carbon dioxide emissions from the power system without the use of nuclear power or emerging technology breakthroughs in both energy efficiency and non-carbon emitting renewable resource generation.”

Nuclear energy: important now more than ever

EN-People-3.jpgThe future of nuclear energy holds tremendous promise, not only in producing carbon-free electricity, but in providing jobs and infrastructure that will boost employment  while providing home-grown energy.

With the national emphasis on STEM education (science, technology, engineering, mathematics), nuclear energy will be the career choice of future engineers and operators, chemists and health physics technicians.

People just like those at Energy Northwest.

Nearly a third of our workforce proudly served our country.

Now we serve Northwest communities with clean, reliable, cost-effective power.

That's who we are. We are the ones who provide the electricity that powers your life.

We do it professionally.

We do it to protect our environment.

And we do it because our mothers and fathers, sons and daughters, deserve clean, reliable, cost-effective electricity.

That’s who we are.

We are Energy Northwest.

C-Bullet.jpg Cost of Power

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.
