Where Oklahoma Gets Its Electricity
Net generation by source · 12-month average, July 2025 – June 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 43.1% | 40,074 GWh |
| Coal | 8.0% | 7,405 GWh |
| Nuclear | 0.0% | 0 GWh |
| Wind | 45.5% | 42,272 GWh |
| Solar | 1.4% | 1,289 GWh |
| Hydro | 1.7% | 1,598 GWh |
| Other | 0.3% | 291 GWh |
92.9 TWh generated over the 12 months to June 2026. Shares are of net generation within Oklahoma, 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. Oklahoma generated 288 GWh that way. Counting it on both sides of the ratio takes solar from 1.4% to 1.7%.
How the mix has shifted since 2001

| Natural gas | 32.5% | 44.7% | +12.3 pts |
| Coal | 62.7% | 10.4% | −52.3 pts |
| Nuclear | 0.0% | 0.0% | — |
| Wind | 0.0% | 41.8% | +41.8 pts |

Oklahoma's generation mix in context
Wind is the largest source of electricity generation in Oklahoma, supplying 44.9% of the total since June 2025. Gas accounts for 43.3%, making it a close second, while coal contributes 8.4%. Solar represents 1.3% of utility-scale generation, or 1.6% when rooftop solar is included. Hydroelectric power generates 1.8%, with other sources making up the remaining 0.3%.
Renewables account for 48.3% of generation, placing Oklahoma 13th among the 51 states and DC. This renewable share runs 23.4 percentage points above the national figure of 24.9%, and sits well ahead of most neighbouring states. New Mexico and Kansas, both bordering Oklahoma to the northwest and north, generate slightly higher renewable shares at 52.7% and 50.1% respectively. The other four neighbours—Colorado, Texas, Missouri and Arkansas—all fall below Oklahoma's renewable portion.
The composition of Oklahoma's generation mix has shifted dramatically since 2001. Wind, which contributed nothing then, has grown to 41.8% by 2025, while coal has fallen from 62.7% to 10.4% over the same period. Gas increased from 32.5% in 2001 to 44.7% in 2025. Renewable generation overall rose from 4.7% in 2001 to 44.9% in 2025, a gain of 40.2 percentage points. Hydroelectric output declined slightly from 4.2% to 1.9%, and solar began generating in the intervening years to reach 0.8% by 2025.

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.
