Mississippi Electricity Rate: What You Need to Know
Mississippi electricity averages 16.16 cents per kWh for residential customers as of May 2026, according to the EIA Electric Power Monthly. This is 2.28c below the US average of 18.44c/kWh. The average monthly bill for Mississippi households is $165 based on typical usage of 1177 kWh.
Mississippi runs on natural gas more than almost any other state - gas fuels roughly 78% of in-state generation, with the Grand Gulf nuclear plant at Port Gibson (the largest single-reactor nuclear unit in the US by capacity) supplying about 14% and a small but growing utility-scale solar share making up most of the rest. That gas-heavy, low-cost base helps hold Mississippi's rate to 16.16c/kWh (May 2026), below the US average of 18.44c, though the state's high average usage of 1,177 kWh per month - driven by heavy summer air conditioning - pushes the typical bill to about $165. The market is regulated with no residential retail choice: Entergy Mississippi serves the western and central parts of the state including the Jackson area, Mississippi Power (a Southern Company subsidiary) serves the southeast around the Gulf Coast, and Cooperative Energy wholesales to the electric cooperatives, all overseen by the Mississippi Public Service Commission. Entergy Mississippi operates under an annual formula rate plan the PSC approved in June 2025 to keep bills roughly 20% below the national average, but a February 2026 fuel adjustment raised bills on higher projected natural gas costs, and the typical residential bill is now about $10.60 a month higher from investments to serve new data-center load.
Generation mix: Natural gas 78%, nuclear 14%, solar 4%, coal 3%. The fuel mix is a primary driver of electricity rates - states with abundant hydro or nuclear tend to have lower rates, while states dependent on imported petroleum (Hawaii) or natural gas pay more.
Year-over-year change: Mississippi rates rose 8.9% year-over-year as of May 2026. This compares to the US average increase of 6.2% over the same period.
