About electricity rates in Mississippi
Mississippi has a regulated market without retail choice. Entergy Mississippi serves the western and central parts of the state including Jackson, Mississippi Power serves the southeast and the Gulf Coast, and the Tennessee Valley Authority supplies local distributors in the northeast. Electric cooperatives, most supplied by Cooperative Energy, serve an unusually large share of the state's households. The elected Mississippi Public Service Commission regulates the investor-owned utilities.
Natural gas dominates generation, with the Grand Gulf nuclear plant, some coal and a growing amount of utility-scale solar making up the rest. Long, hot, humid summers make air-conditioning the main household load, and heat pumps make electric heating common in the mild winters. Rooftop solar is relatively uncommon, and exported power is credited at a rate below the full retail price.
