Where Oregon Gets Its Electricity
Net generation by source · 12-month average, July 2025 – June 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 31.8% | 21,564 GWh |
| Coal | 0.0% | 0 GWh |
| Nuclear | 0.0% | 0 GWh |
| Wind | 14.6% | 9,905 GWh |
| Solar | 4.2% | 2,819 GWh |
| Hydro | 47.9% | 32,501 GWh |
| Other | 1.6% | 1,114 GWh |
67.9 TWh generated over the 12 months to June 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 789 GWh that way. Counting it on both sides of the ratio takes solar from 4.2% to 5.3%.
How the mix has shifted since 2001

Oregon's generation mix in context
Hydropower supplied 47.7% of Oregon's electricity generation from June 2025 to May 2026, making it the largest source by far. Wind added 14.5%, while solar accounted for 4.1% on a utility-scale basis or 5.2% when rooftop solar is included in both the numerator and denominator. Gas generated 32.1%, and other sources made up the remaining 1.7%. Together, renewable sources provided 68.0% of generation, ranking Oregon fifth among all states and DC for renewable share.
Oregon's generation mix has shifted markedly since 2001. Wind grew from 0.2% in 2001 to 14.6% in 2025, while solar rose from nothing to 4.2% in 2025. Hydropower, historically the state's backbone at 63.6% in 2001, declined to 45.1% in 2025. Coal, which supplied 9.9% in 2001, fell to zero by 2025. Gas, by contrast, increased from 24.4% to 34.3% across that span. The renewable share held relatively steady at 65.4% in 2001 and 65.8% in 2025.
Oregon's renewable generation of 68.0% far exceeds the national average of 24.9%, putting it 43.1 percentage points ahead. Its carbon-free share of 68.0% also significantly outpaces the nation's 42.6%. Among its neighbours, Washington and Idaho both surpass Oregon with renewable shares of 77.1% and 74.3% respectively, while California and Nevada fall below it at 57.3% and 43.7%. Solar generation ranks Oregon 27th among the 51 states and DC.

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 June 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.
