Where Missouri Gets Its Electricity
Net generation by source · 12-month average, July 2025 – June 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 13.3% | 9,665 GWh |
| Coal | 57.1% | 41,435 GWh |
| Nuclear | 13.6% | 9,859 GWh |
| Wind | 9.8% | 7,105 GWh |
| Solar | 3.8% | 2,760 GWh |
| Hydro | 1.3% | 952 GWh |
| Other | 1.0% | 741 GWh |
72.5 TWh generated over the 12 months to June 2026. Shares are of net generation within Missouri, 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. Missouri generated 840 GWh that way. Counting it on both sides of the ratio takes solar from 3.8% to 4.9%.
How the mix has shifted since 2001

Compared with the U.S. and nearby states
Missouri's generation mix in context
Coal is Missouri's largest generation source, supplying 58.4% of the state's electricity in the year from June 2025 to May 2026. Gas accounts for 13.6%, nuclear for 12.4%, and wind for 9.7%. Solar, counted as utility-scale alone, represents 3.5% of generation, though rooftop solar brings that share to 4.6% when included. Together, renewable sources account for 14.7% of generation, placing Missouri 30th among the 51 states and DC with generation data. Carbon-free sources, combining renewables with nuclear, make up 27.1%.
Since 2001, Missouri's generation mix has shifted considerably. Coal has fallen from 82.7% in 2001 to 63.7% in 2025, a decline of 19 percentage points. Wind grew from zero to 9.0% in 2025, while solar rose from nothing to 2.2%. Gas more than doubled from 4.9% to 13.1%. Renewables overall climbed from 1.4% in 2001 to 12.8% in 2025.
Compared with the national mix, Missouri relies far more heavily on coal—42.6 percentage points higher than the 15.8% average—and significantly less on gas, at 27.2 points below the 40.8% national share. Missouri's renewable share of 14.7% trails the national figure of 24.9% by 10.2 percentage points. Among its eight bordering states, five generate a higher proportion from renewables, including Iowa at 61.5% and Kansas at 50.1%. Only Arkansas and Kentucky generate smaller renewable shares than Missouri.

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.
