Where Mississippi Gets Its Electricity
Net generation by source · 12-month average, July 2025 – June 2026.
Generation mix
| Source | Share | Generation |
|---|---|---|
| Natural gas | 75.7% | 58,662 GWh |
| Coal | 4.5% | 3,471 GWh |
| Nuclear | 13.1% | 10,151 GWh |
| Wind | 0.7% | 527 GWh |
| Solar | 4.3% | 3,294 GWh |
| Hydro | 0.0% | 0 GWh |
| Other | 1.7% | 1,347 GWh |
77.5 TWh generated over the 12 months to June 2026. Shares are of net generation within Mississippi, 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. Mississippi generated 36 GWh that way. Counting it on both sides of the ratio takes solar from 4.3% to 4.3%.
How the mix has shifted since 2001
| Source | 2001 | 2025 | Change |
|---|---|---|---|
| Natural gas | 33.2% | 73.9% | +40.7 pts |
| Coal | 35.9% | 5.4% | −30.6 pts |
| Nuclear | 18.6% | 14.7% | −3.9 pts |

Compared with the U.S. and nearby states
Mississippi's generation mix in context
Natural gas supplied 75.7% of Mississippi's electricity generation in the twelve months from June 2025 to May 2026, making it the dominant source. Carbon-free generation—nuclear and renewables together—accounted for 19.5% of the total. Nuclear power contributed 13%, while renewables made up 6.6%. Solar generated 4.2% of electricity whether counted as utility-scale alone or including rooftop solar; wind supplied 0.7%. Coal fell to 4.7%, and other sources, which include geothermal and biomass among other fuels, made up 1.7%.
Mississippi's renewable share of 6.6% places it 45th among the 51 states and DC with generation data. Its solar share ranks 24th. Compared with the national generation mix, Mississippi relies far more heavily on natural gas—34.9 percentage points above the national share of 40.8%—and much less on renewables, which stood at 24.9% nationwide. Among its four bordering states, three generate higher renewable shares: Arkansas at 13.8%, Tennessee at 12.5%, and Alabama at 8.4%. Louisiana's renewable share of 5.1% is lower than Mississippi's.
The generation mix has shifted markedly since 2001. Gas surged from 33.2% in 2001 to 73.9% in 2025, while coal collapsed from 35.9% to 5.4%. Renewables grew from 2.7% in 2001 to 6.0% in 2025, driven almost entirely by solar, which rose from nothing to 3.7%. Wind began from zero and reached 0.6%. Nuclear declined slightly from 18.6% to 14.7%, and other sources fell from 12.3% to 1.7%.

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 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.
