Power Supply

Clean, renewable power... Our future includes a diversified mix of green resources with an eye on our environment.

Currently, most of our power is purchased from the Bonneville Power Administration (BPA), and most of BPA’s power is generated by dams built by the federal government throughout the Pacific Northwest — primarily on the Columbia and Snake rivers.

We are also actively researching and developing other sources of power in an effort to create a more balanced mix of energy sources and help reduce our dependence on energy from BPA. These efforts include our current power sources (hydroelectric, biomass, wind, and landfill gas) as well as those in development (tidal and geothermal). You can also learn more about what the Snohomish County PUD is doing to meet future growth and invest in renewable energy sources in our Integrated Resource Plan.

Our Energy Sources:

Washington state law requires utilities to publish their fuel mix for customers. The chart below indicates the types of fuel sources the PUD used during 2011:
Biomass 2%
Coal 4%
Hydroelectric Generation 88%
Natural Gas Generation 1%
Nuclear Generation (BPA-supplied) 4%
Other Generation 1%
Based on data from the state of Washington as of 12/31/11 (year-end figures updated each spring of the following year). Other generation includes cogeneration, landfill gas, petroleum and waste.


A portion of the PUD's environmental attributes have been sold to fund the utility's renewable energy R&D projects.
