Where We Get Our Power

The chart below shows the components of the District’s “fuel mix,” — the sources of power production used to serve the District’s customers. New industrial customers are served with unspecified market sources, including natural gas, hydro, and wind. The nuclear power shown is energy the Bonneville Power Administration (BPA)purchases from the Columbia Generating Station in southeastern Washington and is part of the BPA’s overall mix of power resources. Unspecified resources are purchases from non-federal suppliers that may consist of a mix of hydro, natural gas, wind, and other energy that varies by season and time of day.

NWCPUD Power Resources

Hydroelectric Resources

The PUD operates two small hydroelectric power plants on the Columbia River. These facilities provide clean, fish-friendly, and renewable energy.

The Dalles North Fishway Hydroelectric Project

Northern Wasco County PUD’s The Dalles North Fishway Hydroelectric Project produced its first commercial power on May 28, 1991. The 5-megawatt generator uses attraction to water from The Dalles dam’s north fish ladder for power production.

Dalles North Fishway Hydroelectric ProjectWater entering the plant is screened to prevent juvenile salmon or other small fish from entering the unit’s turbine. This protective measure permits the project to be eligible for Low Impact Hydroelectric Institute certification Website and Renewable Energy Credits.

The powerhouse has produced enough electricity to power about 4,000 average-sized homes per year. The power produced by The Dalles Fishway plant is currently being sold to other regional entities. Revenues offset PUD customers’ electric rates and keep them lower.

McNary Dam Washington Shore Fishway Project

Lihi Certified logoThe McNary Dam hydroelectric project was completed and started production on October 17, 1997. The generating unit is located on the north-shore fish ladder at McNary Dam, near Umatilla, Oregon, and uses the fish ladder’s attraction water in the same way The Dalles project does.

The intake structure at McNary is located at the bottom of the dam and draws water from about 80 feet below the surface. The generator at McNary produces 10 megawatts of power, which is split equally with our partner, Klickitat County PUD. Northern Wasco’s portion of the power is transmitted to The Dalles and is used to serve utility customers.

The McNary plant generates enough electricity to serve about 3,800 average-size homes per year.

About one-half of the utility’s power comes from hydroelectricity — And nearly all of the electricity consumed by PUD residential and commercial customers is either renewable or generated from sources that don’t use fossil fuels.

Bonneville Power Administration

NWCPUD is a preferred customer of the Bonneville Power Administration (BPA) www.bpa.gov. BPA is a nonprofit federal power marketing administration that markets wholesale electric power from 31 federal hydroelectric projects in the Pacific Northwest, one non-federal nuclear power plant, and several small non-federal power plants. The Federal Columbia River Power System (FCRPS) is NWCPUD’s largest source of electric power used to serve residential and commercial customers.
