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.

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.

From time to time, a portion of the environmental attributes from the PUD's renewable resources may been sold, which funds the utility's ongoing renewable energy and R&D projects.
