4-County 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.
4-County Electric Power Assn is an electric cooperative that reported 41,076 residential customers in Mississippi on Form EIA-861 for 2024, with a service territory that touches 7 counties.
Its average residential price that year was 12.88¢ per kilowatthour, 3.8% below the Mississippi average of 13.39¢ and 22% 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 $156.25 a month on average use of 1,213 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 214.7 minutes per customer with major event days included and 123.7 minutes with them excluded, calculated under another method. The median among Mississippi utilities reporting was 324.6 minutes with major event days; this utility's figure is 34% below that median.
The average price is up 10.6% on 2019, against up 18.8% for Mississippi as a whole, and up 1.9% on 2023.

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 244 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 1.94 interruptions per customer with major event days, 1.57 without; CAIDI 110.4 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.
