Clean energy

As a leader in carbon-free energy, 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 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: hydropower, biogas, biofuel, landfill gas, wind, and solar. You can also learn more about what the PUD is doing to meet future growth and invest in renewable energy sources in our Integrated Resource Plan.

Our Energy Sources:

2021 Fuel Mix. Washington state law requires utilities to publish their fuel mix for customers.

Hydroelectric 84%
Nuclear 1 11%
Solar 0%
Wind 2%
Unspecified 1, 2 4%
Total 100%
Total may exceed 100% due to rounding.

2The 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
