Tennessee Electricity Prices

Relatively, yes — 14.47¢ per kilowatt-hour in May 2026, 12th-cheapest of 51 and 25.5% below the national benchmark.

At Tennessee's May 2026 average of 14.47¢/kWh, 10,500 kWh of annual use works out to $1,519 a year — around $127 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,038 — a $519 gap between the two published averages, less for Tennessee, not a bill either way.

Over the full EIA series the Tennessee jurisdiction average has risen 137% since January 2001, from 6.11¢ to 14.47¢ in May 2026 — a compound 3.5% per year. The path has been unusually smooth — Tennessee is among the steadiest third of jurisdictions month to month.

March 2026, at 15.08¢ per kilowatt-hour. The May 2026 reading of 14.47¢ sits 4.0% below that peak. The lowest monthly average on record was 6.11¢ in January 2001.

November. Measured over the 25 complete calendar years the EIA series covers for Tennessee, 2001 through 2025, November runs highest relative to its own year and February runs lowest — a swing of roughly 8.3 percentage points.

Among Tennessee and its land-border neighbours in May 2026, Tennessee posts the lowest average at 14.47¢ and Alabama the highest at 16.77¢. That makes Tennessee the cheapest in the group, at 14.47¢.

Almost certainly not exactly, and this is the one caveat that governs every figure on this page. The published value is the EIA residential average across every utility and residential rate class in Tennessee for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 12.82¢ in February 2026 and 15.08¢ in March 2026. Your own rate depends on your utility, tariff, usage tier, time-of-use schedule, and fixed monthly charges, none of which this index models. Read your bill for the rate that applies to you.
