Town of Erwin
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, Town of Erwin, a municipal utility, reported 7,618 residential customers in Tennessee, with a service territory that touches 3 counties.
Its average residential price that year was 12.23¢ per kilowatthour, about the same as the Tennessee average of 12.42¢ and 26% 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 $123.94 a month on average use of 1,013 kWh a month. Across Tennessee the average bill was $143.32 on 1,154 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 102.2 minutes per customer with major event days included and 102.2 minutes with them excluded, calculated under another method. The median among Tennessee utilities reporting was 270.1 minutes with major event days; this utility's figure is 62% below that median.
The average price is up 9.8% on 2019, against up 14.3% for Tennessee as a whole, and little changed on 2023. EIA's early release for 2025, which has not been fully edited, shows 13.14¢.

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 | 7,618 | 92.6 GWh | 48% | $11,330,000 | 12.23¢ |
| Commercial | 1,387 | 53.3 GWh | 28% | $7,014,000 | 13.17¢ |
| Industrial | 3 | 46.3 GWh | 24% | $3,790,000 | 8.19¢ |
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: 198.5 GWh in total, of which 0% was its own net generation and 198.5 GWh was bought wholesale; summer peak demand 39 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under another method. SAIFI: 3.36 interruptions per customer with major event days, 3.36 without; CAIDI 30.4 minutes per interruption. EIA's Tennessee total across all reporting utilities was 278.6 minutes with major event days and 159.5 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.
