Regulated: your utility sets the rate
You cannot shop for supply in Tennessee
Tennessee is a regulated market. Your utility is your only option for supply, and the rate is set through a public commission process rather than by competition. Pricing tends to be more stable than in deregulated states, and there is no switching decision to make.
That makes the levers on your side of the meter the only ones available: what you run, for how long, and whether you generate any of it yourself.
What every appliance costs to run in Tennessee
All figures below are computed at the Tennessee rate of 14.47 cents. The last column shows the annual difference against the same appliance at the national average, which is where the effect of living here actually shows up.
At 14.47 cents, Tennessee sits close enough to the national average that solar payback here tends to track the national picture. The variables that decide it are local: net metering terms, state incentives, roof orientation and shading.
Typical peak sun hours across the Southeast region run around 4.5 to 5 hours a day as an annual average, though the spread within a region can be wide. For a figure based on your actual location rather than a regional band, use the location-based solar production calculator, and the solar payback calculator for the financial side.

Why is my electricity bill higher than the Tennessee average?

Costs on this page use a national average residential rate of 18.44¢ per kWh (August 2026, EIA-derived state residential averages). Your own rate is printed on your electricity bill and is the number that actually matters. Every figure here is recalculated from one central rate setting, so these tables move when the national average moves.
