In Oregon, our electricity comes from a variety of resources, including hydroelectricity, natural gas, coal, wind, nuclear, and solar.

About the Electricity Resource Mix
The Oregon Department of Energy collects electricity resource data from our state’s utility providers. The information helps us – and Oregonians across the state – track power sources and better understand the environmental effects of the electricity we use. Our analysis takes into account all electricity that serves Oregon, including electricity that is generated outside the state and delivered to Oregon customers.

More About the Methodology Change
The methodology for how ODOE collects and presents electricity market purchases in Oregon’s Electricity Resource Mix changed starting with the 2022 data. ODOE now collects data on electricity produced for Oregon consumers from the Oregon Department of Environmental Quality, rather than directly from utilities. Since electricity generation is a primary input for DEQ's state Greenhouse Gas Reporting Program, this process ensures consistent use of energy data across state agencies, while using a more efficient data collection process for the utilities.
ODOE had previously produced utility-specific information using a contractor who analyzed detailed resources data from across the Pacific Northwest regional market. In the past, this assessment was sufficient to produce a reasonable assessment of a market purchases resource mix, but growth in participation in energy imbalance markets and increasing reliance on electric utility market purchases has made this process more challenging and will produce increasingly less certain results. As a result, at this time ODOE no longer calculates and provides utility-specific data but instead relies on a regional metric from DEQ. Visitors to this page will now see an "Unspecified" resource bubble; these are purchases made on the open market where we don't know exactly what resource supplied that power to sell to customers. ODOE will continue to track developments of electricity markets and resources to assess the make-up of unspecified power over time.
