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:
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%|
|Natural Gas Generation 1||0%|
|Nuclear Generation 2||10%|
|Other Generation 3||1%|
|Unspecified 2, 4||5%|
|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.
