Middle Tennessee E M C
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Annual figures: Form EIA-861 for 2024, final release. Monthly state figures run to July 2026.
Middle Tennessee E M C is an electric cooperative that reported 307,370 residential customers in Tennessee on Form EIA-861 for 2024, with a service territory that touches 8 counties.
Its average residential price that year was 11.76¢ per kilowatthour, 5.3% below the Tennessee average of 12.42¢ and 29% below the US average of 16.48¢. The figure is residential revenue divided by residential sales, so it folds in fixed charges, riders and every rate schedule the utility bills under.
That works out to an average residential bill of $148.33 a month on average use of 1,261 kWh a month. Across Tennessee the average bill was $143.32 on 1,154 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
For reliability it reported a SAIDI of 49.4 minutes per customer with major event days included and 41.8 minutes with them excluded, calculated under IEEE 1366 standard. The median among Tennessee utilities reporting was 270.1 minutes with major event days; this utility's figure is 82% below that median.
The average price is up 16.1% on 2019, against up 14.3% for Tennessee as a whole, and up 3.6% on 2023. EIA's early release for 2025, which has not been fully edited, shows 12.47¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 307,370 | 4.7 TWh | 54% | $547,097,000 | 11.76¢ |

Customers, sales and revenue count every service type the utility reported (bundled, energy-only and delivery-only). The price column uses bundled service alone, because part-bill revenue would understate it. Sources of energy: 8.9 TWh in total, of which 0% was its own net generation and 8.9 TWh was bought wholesale; summer peak demand 1,989 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 0.93 interruptions per customer with major event days, 0.88 without; CAIDI 52.9 minutes per interruption. EIA's Tennessee total across all reporting utilities was 278.6 minutes with major event days and 159.5 without. Major event days are storms and similar events that a utility's chosen method sets apart; methods differ, so treat comparisons as approximate. What SAIDI and SAIFI mean.
