Where Oregon Gets Its Electricity
Net generation by source · 12-month average, September 2025 – August 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 32.1% | 21,624 GWh |
| Coal | 0.0% | 0 GWh |
| Nuclear | 0.0% | 0 GWh |
| Wind | 14.6% | 9,847 GWh |
| Solar | 4.2% | 2,861 GWh |
| Hydro | 47.4% | 31,915 GWh |
| Other | 1.6% | 1,082 GWh |
67.3 TWh generated over the 12 months to August 2026. Shares are of net generation within Oregon, which is not the same as what the state consumes — power crosses state lines.
Counting rooftop solar
EIA reports small-scale solar — mostly rooftop panels on homes and businesses — separately, and leaves it out of the state generation total that the mix above is a share of. Oregon generated 815 GWh that way. Counting it on both sides of the ratio takes solar from 4.2% to 5.4%.
How the mix has shifted since 2001

Oregon's generation mix in context
Hydroelectric generation supplied 47.4% of Oregon's electricity from September 2025 to August 2026, making it the largest source by far. Gas accounted for 32.1% of the total, with renewables comprising 68.0% of the state's generation. The solar share was 4.2% from utility-scale facilities alone, or 5.4% when rooftop solar is included in the count.
Oregon's renewable share ranks fifth of the 50 states and DC, well ahead of the national average of 25.4%. The state's carbon-free generation matched its renewable share at 68.0%, compared with a national carbon-free figure of 43.0%. Fossil fuels made up 32.1% of Oregon's mix—entirely gas, since the state generated no coal or nuclear electricity. Two of Oregon's four bordering states, Washington and Idaho, each generate higher shares of renewables, while California and Nevada each generate lower shares.
Between 2001 and 2025, Oregon's generation mix shifted toward gas and wind. Gas rose from 24.4% in 2001 to 34.3% in 2025, while wind grew from 0.2% in 2001 to 14.6% in 2025. Hydroelectric generation fell from 63.6% in 2001 to 45.1% in 2025, a decline of 18.5 percentage points. The state's overall renewable share grew slightly, from 65.4% in 2001 to 65.8% in 2025, a gain of 0.4 percentage points.

How this is measured
Figures are net generation reported to the U.S. Energy Information Administration for all sectors — utilities, independent power producers, and industrial and commercial plants that generate their own power. Shares are of the 12 months to August 2026, rather than a single month, because generation is strongly seasonal: solar peaks in summer and hydro with the spring melt, so one month says more about the weather than about the grid.
“Other” is the reported total minus the six named sources, so the shares add to exactly 100%. It holds geothermal, biomass, petroleum, other gases, and pumped storage — the last of which consumes more electricity than it returns, and so can be negative. Geothermal and biomass are renewable, which is why the renewable share above is slightly larger than wind, solar and hydro added together.
This is generation, not consumption. Electricity crosses state lines freely, so a state can generate more than it uses or rely on imports for a large part of its supply; neither shows up here.
