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 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 solar) as well as assessment and potential development of small hydroelectric and geothermal 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 2015:

Coal Generation1 2%
Hydroelectric Generation 87%
Natural Gas Generation1 1%
Nuclear Generation2 10%
Wind Generation 0%
Total 100%
Based on data received from the state of Washington on 5/3/17 (year-end figures updated each summer of the following year).

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. The state requires the PUD to assume that a portion of these market purchases are attributed to coal even though the utility intentionally strives to avoid purchases from carbon-emitting resources. 

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