City of Marietta
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.
City of Marietta serves 36,273 residential customers in Georgia as a municipal utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 1 county.
Its average residential price that year was 11.93¢ per kilowatthour, 15% below the Georgia average of 14.08¢ and 28% 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 $99.04 a month on average use of 830 kWh a month. Across Georgia the average bill was $151.25 on 1,074 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 128.6 minutes per customer with major event days included and 128.6 minutes with them excluded, calculated under IEEE 1366 standard. The median among Georgia utilities reporting was 392.5 minutes with major event days; this utility's figure is 67% below that median.
The average price is up 1.9% on 2019, against up 19.7% for Georgia as a whole, and up 1.6% on 2023. EIA's early release for 2025, which has not been fully edited, shows 11.92¢.

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 | 36,273 | 361.3 GWh | 37% | $43,110,700 | 11.93¢ |
| Commercial | 6,233 | 607.8 GWh | 63% | $72,414,200 | 11.91¢ |
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: 1.4 TWh in total, of which 0% was its own net generation and 1.4 TWh was bought wholesale; summer peak demand 219 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 1.69 interruptions per customer with major event days, 1.69 without; CAIDI 75.9 minutes per interruption. EIA's Georgia total across all reporting utilities was 1,229.1 minutes with major event days and 212.3 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.
