Fuel Mix Summary

2019 Fuel Mix

All Washington utilities report their sources of electricity to the Department of Commerce and they combine the information with data from wholesale markets to determine a fuel mix summary for each utility. The fuel mix is based on the generating plants and contracts of each utility and the Bonneville Power Administration.  The report is published by the Department of Commerce and the 2019 report is available using the link under the  publications section above. Please note - the data for 2020 is currently being compiled.

Washington State Law requires the PUD to disclose the mix of fuels used to generate the electricity sold to its customers (under RCW 19.29A).
