Lockhart Power 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.
Lockhart Power Co serves 4,976 residential customers in South Carolina as an investor-owned utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 5 counties.
Its average residential price that year was 13.42¢ per kilowatthour, 5.7% below the South Carolina average of 14.23¢ 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 $143.28 a month on average use of 1,068 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.
EIA's reliability file has no SAIDI or SAIFI entry for it in 2024; smaller respondents and energy-only suppliers are not asked for one.
The average price is little changed on 2019, against up 9.5% for South Carolina as a whole, and down 6.7% on 2023. EIA's early release for 2025, which has not been fully edited, shows 14.23¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 4,976 | 63.8 GWh | 9% | $8,555,800 | 13.42¢ |

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: 993.7 GWh in total, of which 10.5% was its own net generation and 889.7 GWh was bought wholesale; summer peak demand 105 MW.
Reliability
EIA's reliability file has no entry for Lockhart Power Co in 2024. Energy-only suppliers do not own the wires, and the smallest distribution utilities are not asked for SAIDI and SAIFI.
Generation at plants it operates, 2025
- Hydro 77.3% 54.1 GWh
- Other 22.6% 15.8 GWh
- Petroleum 0.1% 97 MWh
Net generation of 69.9 GWh at power plants this utility operates, from Form EIA-923. It is not the mix delivered to customers: utilities also buy power wholesale (889.7 GWh in 2024), sell generation to others and may co-own plants that another company operates.
