Tombigbee Electric Power Assn
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.
Tombigbee Electric Power Assn serves 37,296 residential customers in Mississippi as an electric cooperative, according to its 2024 Form EIA-861 filing, with a service territory that touches 4 counties.
Its average residential price that year was 12.23¢ per kilowatthour, 8.7% below the Mississippi average of 13.39¢ and 26% 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 $155.40 a month on average use of 1,271 kWh a month. Across Mississippi the average bill was $154.83 on 1,156 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
EIA's reliability file has no SAIDI or SAIFI entry for it in 2024; smaller respondents and energy-only suppliers are not asked for one.
The average price is up 13.5% on 2019, against up 18.8% for Mississippi as a whole, and up 2.7% on 2023. EIA's early release for 2025, which has not been fully edited, shows 13.03¢.

Bundled residential service only in the price, bill and use columns. Bill = residential revenue ÷ customers ÷ 12; use = residential sales ÷ customers ÷ 12. EIA describes its early release as not fully edited; it is shown for this utility alone and enters no average, median or rank on this site.

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: 1.2 TWh in total, of which 0% was its own net generation and 1.2 TWh was bought wholesale; summer peak demand 260 MW.
