Santee Electric Coop, Inc
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.
Santee Electric Coop, Inc is an electric cooperative that reported 35,235 residential customers in South Carolina on Form EIA-861 for 2024, with a service territory that touches 4 counties.
Its average residential price that year was 14.74¢ per kilowatthour, 3.6% above the South Carolina average of 14.23¢ and 11% 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 $184.48 a month on average use of 1,251 kWh a month. Across South Carolina the average bill was $149.51 on 1,050 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 441.9 minutes per customer with major event days included and 147.0 minutes with them excluded, calculated under IEEE 1366 standard. The median among South Carolina utilities reporting was 733.2 minutes with major event days; this utility's figure is 40% below that median.
The average price is up 5.7% on 2019, against up 9.5% for South Carolina as a whole, and up 3.6% on 2023. EIA's early release for 2025, which has not been fully edited, shows 16.39¢.

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 | 35,235 | 529.1 GWh | 46% | $78,003,000 | 14.74¢ |

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 237 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: —. EIA's South Carolina total across all reporting utilities was 3,136.5 minutes with major event days and 117.8 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.
