About electricity rates in Tennessee
Tennessee's electricity comes almost entirely from the Tennessee Valley Authority, a federal corporation that generates and transmits power and sells it to local power companies, which are municipal utilities and cooperatives such as Nashville Electric Service and Memphis Light, Gas and Water. There are no investor-owned utilities of any size, there is no retail choice, and rates are set by TVA and its local distributors rather than by a state commission.
TVA's mix leans on nuclear plants, natural gas, hydropower from its dams and a declining amount of coal. Hot, humid summers drive air-conditioning use, and because electric heating is widespread, winter cold snaps also bring high demand. Rooftop solar is handled through TVA programs rather than conventional net metering.
