Power Supply

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

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 continually researching and developing other sources of power in an effort to create a more balanced mix of energy sources and help supplement our purchases from BPA with clean, renewable energy. These efforts include our current power sources (hydroelectric, biomass, wind, and solar) as well as assessment and potential development of small hydroelectric projects. 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 2019:

Coal Generation 1 0%
Hydroelectric Generation 76%
Natural Gas Generation 1 0%
Nuclear Generation 2 10%
Wind Generation 8%
Other Generation 3 1%
Unspecified 2, 4
Total 100%

Note: Total may not add up to 100% due to rounding.

Based on data received from the state of Washington on 9/11/20.

1The PUD does not have coal or natural gas resources in its power supply portfolio. It does make market purchases to balance or match its loads and resources. These purchases, along with market purchases made by BPA, may incidentally include coal or natural gas resources, which are assigned to the utility.


3Includes biomass, other bio-genic/non-biogenic, solar, biogas.

4The 2019 Legislative update to the Fuel Mix Disclosure requirement adds a new category for "unspecified resources" of electric power. For information on this update, visit the Washington State Department of Commerce website: Fuel Disclosure
