East-Central Iowa Rural Elec Coop
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-Central Iowa Rural Elec Coop is an electric cooperative that reported 7,368 residential customers in Iowa on Form EIA-861 for 2024, with a service territory that touches 11 counties.
Its average residential price that year was 13.28¢ per kilowatthour, about the same as the Iowa average of 13.40¢ and 19% 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 $178.84 a month on average use of 1,346 kWh a month. Across Iowa the average bill was $111.54 on 832 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 37.9 minutes per customer with major event days included and 37.9 minutes with them excluded, calculated under IEEE 1366 standard. The median among Iowa utilities reporting was 85.7 minutes with major event days; this utility's figure is 56% below that median.
The average price is up 20.8% on 2019, against up 7.5% for Iowa as a whole, and up 2.1% on 2023. EIA's early release for 2025, which has not been fully edited, shows 13.13¢.

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 | 7,368 | 119 GWh | 56% | $15,812,000 | 13.28¢ |

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: 224 GWh in total, of which 0% was its own net generation and 224 GWh was bought wholesale; summer peak demand 45 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 0.53 interruptions per customer with major event days, 0.53 without; CAIDI 71.4 minutes per interruption. EIA's Iowa total across all reporting utilities was 166.7 minutes with major event days and 89.8 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.
