Tennessee at a glance
Tennessee is served by the Tennessee Valley Authority, a federal public power provider with a diverse nuclear, hydroelectric and natural gas mix, which keeps rates low without investor returns in the rate base. Retail choice does not exist. Humid summers drive cooling demand, and electric heating is common enough that winter carries substantial load.
