East Mississippi Elec Pwr 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.
East Mississippi Elec Pwr Assn serves 9,885 residential customers in Mississippi as an electric cooperative, according to its 2024 Form EIA-861 filing, with a service territory that touches 10 counties.
Its average residential price that year was 14.26¢ per kilowatthour, 6.5% above the Mississippi average of 13.39¢ and 13% 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 $152.10 a month on average use of 1,067 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.
For reliability it reported a SAIDI of 663.0 minutes per customer with major event days included and 468.0 minutes with them excluded, calculated under IEEE 1366 standard. The median among Mississippi utilities reporting was 324.6 minutes with major event days; this utility's figure is 104% above that median.
The average price is up 9.6% on 2019, against up 18.8% for Mississippi as a whole, and little changed on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.94¢.

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.
Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 9,885 | 126.5 GWh | 58% | $18,042,000 | 14.26¢ |
| Commercial | 3,351 | 91.1 GWh | 42% | $12,626,000 | 13.86¢ |
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: 232.8 GWh in total, of which 0% was its own net generation and 232.8 GWh was bought wholesale; summer peak demand 51 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 3.63 interruptions per customer with major event days, 2.81 without; CAIDI 182.6 minutes per interruption. EIA's Mississippi total across all reporting utilities was 567.1 minutes with major event days and 266.3 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.
