Where Oregon Gets Its Electricity
Net generation by source · 12-month average, June 2025 – May 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 32.1% | 21,713 GWh |
| Coal | 0.0% | 0 GWh |
| Nuclear | 0.0% | 0 GWh |
| Wind | 14.5% | 9,775 GWh |
| Solar | 4.1% | 2,780 GWh |
| Hydro | 47.7% | 32,211 GWh |
| Other | 1.7% | 1,119 GWh |
67.6 TWh generated over the 12 months to May 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 777 GWh that way. Counting it on both sides of the ratio takes solar from 4.1% to 5.2%.
How the mix has shifted since 2016

| Natural gas | 25.4% | 34.3% | +8.9 pts |
| Coal | 3.2% | 0.0% | −3.2 pts |
| Nuclear | 0.0% | 0.0% | — |
| Wind | 11.9% | 14.6% | +2.8 pts |
| Solar | 0.1% | 4.2% | +4.1 pts |
| Hydro | 57.4% | 45.1% | −12.3 pts |

Oregon's generation mix in context
Hydroelectric generation supplied 47.7% of Oregon's electricity since June 2025, making it the largest source. Renewables accounted for 68.0% of the state's generation, matching its carbon-free share since Oregon generated no electricity from coal or nuclear power. When rooftop solar is counted alongside utility-scale solar, the solar share rises to 5.2%, though utility-scale solar alone makes up 4.1% of generation. Oregon ranked fifth among the 51 states and DC for renewable generation share, well above the national renewable average of 24.9%. Its fossil fuel share of 32.1% came from gas, which was 8.7 percentage points lower than the national figure of 40.8%.
Over the decade since 2016, Oregon's generation mix shifted away from hydroelectric power, which fell from 57.4% in 2016 to 45.1% in 2025, a decline of 12.3 percentage points. Gas generation rose to fill part of that gap, growing from 25.4% to 34.3%. Wind grew modestly, from 11.9% to 14.6%, while solar expanded dramatically from 0.1% in 2016 to 4.2% in 2025. Overall renewable generation fell from 71.3% in 2016 to 65.8% in 2025. Among bordering states, Washington and Idaho both had higher renewable shares at 77.1% and 74.3% respectively, while California and Nevada were lower at 57.3% and 43.7%.

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 May 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.
