City of St Marys
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 2023, final release. Monthly state figures run to July 2026.
City of St Marys serves 3,758 residential customers in Ohio as a municipal utility, according to its 2023 Form EIA-861 filing, with a service territory that touches 1 county.
Its average residential price that year was 13.49¢ per kilowatthour, 12% below the Ohio average of 15.38¢ and 16% below the US average of 16.00¢. 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 $105.66 a month on average use of 783 kWh a month. Across Ohio the average bill was $124.68 on 811 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 2023; smaller respondents and energy-only suppliers are not asked for one.
The average price is up 8.3% on 2018, and up 3.8% on 2022.
