Southern Indiana Gas & Elec Co
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.
In its Form EIA-861 filing for 2024, Southern Indiana Gas & Elec Co, an investor-owned utility, reported 133,795 residential customers in Indiana, with a service territory that touches 7 counties.
Its average residential price that year was 17.52¢ per kilowatthour, 19% above the Indiana average of 14.77¢ and 6.3% above 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 $155.32 a month on average use of 886 kWh a month. Across Indiana the average bill was $133.06 on 901 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 458.0 minutes per customer with major event days included and 81.2 minutes with them excluded, calculated under another method. The median among Indiana utilities reporting was 196.1 minutes with major event days; this utility's figure is 134% above that median.
The average price is up 14.2% on 2019, against up 17.4% for Indiana as a whole, and up 1.6% on 2023.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 133,795 | 1.4 TWh | 30% | $249,368,500 | 17.52¢ |

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: 5.1 TWh in total, of which 38.8% was its own net generation and 3 TWh was bought wholesale; summer peak demand 1,178 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 1.43 interruptions per customer with major event days, 0.79 without; CAIDI 320.3 minutes per interruption. EIA's Indiana total across all reporting utilities was 312.4 minutes with major event days and 121.4 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.
