Thermal power

While hydropower makes up the largest share of electricity we provide to our customers, electricity from natural gas-fired and coal-fired power plants also represents a substantial portion of our supply.

 

Gas-fired power

PSE owns nine natural gas-fired power plants with a combined generating capacity of approximately 1,900 megawatts. The latest addition to the utility’s gas-fired fleet is the 270-megawatt Ferndale Generating Station. PSE acquired the Whatcom County facility in late 2012.

In addition to the Ferndale plant, we have gas-fired power-generating facilities in Pierce (Frederickson, with two facilities), Skagit (Fredonia), Cowlitz (Mint Farm) and Klickitat (Goldendale) counties, as well as three other plants (WhitehornEncogen and Sumas) in Whatcom County.

Gas-fired power is safe, requires no disposal or storage of dangerous wastes and emits far less carbon dioxide than other power resources that use fossil fuels.

Coal-fired power

The Colstrip Power Project in eastern Montana is the single largest power-generating facility that we own, providing approximately 700 megawatts of generating capacity.
