Electricity rates & appliance costs in Tennessee

Why electricity costs 13.71¢/kWh in Tennessee

Hot summers drive cooling demand; nuclear generation supplies most of the load.

Large nuclear fleet keeps rates among the lowest in the country.

At 13.71¢/kWh, Tennessee sits well below the 18.3¢ U.S. average. That works out to $137.10 for every 1,000 kWh used — so a 1,500 W space heater costs $0.21 an hour to run, and a family heating with electric resistance instead of gas feels that difference in every winter month.

How Tennessee compares with neighbouring states

Tennessee ranks 47th of 51 jurisdictions by residential price, from Hawaii at 48.00¢ down to Louisiana at 12.72¢ — a spread of about 3.8× across the country. Identical appliance habits can therefore cost several times more in one state than another.

Across East South Central — the regional grouping the EIA itself uses for comparison — the average rate including Tennessee is 14.62¢/kWh, so Tennessee pays $0.90 less per kWh than that regional average. On a 1,500 W space heater running 6 hours a day, that gap alone is about $247.97 a month.

• Kentucky13.8¢
• Mississippi14.5¢
• Alabama16.4¢

What Tennessee households actually pay

A typical U.S. household uses around 30 kWh a day, about 900 kWh a month. At 13.71¢/kWh that is roughly $123 a month in electricity, or $1,481 a year. That is about $41 less per month than the same usage at the national average — a real saving on the same appliances.

Because the rate is a per-kWh price, the fastest savings come from the biggest loads: cutting a 1,500 W space heater from 6 hours a day to 3 saves about $19 a month in Tennessee. That is why the calculators here use your state rather than a national guess.

Reading your Tennessee utility bill

The EIA figure is a state average across utilities, not your tariff. Your bill shows your exact "price to compare" in ¢/kWh plus fixed customer charges, and sometimes tiered or time-of-use pricing. In a deregulated market you may also have chosen a retail supplier whose rate differs from the utility default.

The calculators use the published state average, which is the right basis for comparing appliances against each other. For a figure that matches your own bill, take the "price to compare" line and use it as your rate.
