Duke Energy Florida, LLC
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.
Duke Energy Florida, LLC serves 1,793,067 residential customers in Florida as an investor-owned utility, according to its 2024 Form EIA-861 filing, with a service territory that touches 32 counties.
Its average residential price that year was 16.63¢ per kilowatthour, 18% above the Florida average of 14.14¢ and about the same as 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 $170.34 a month on average use of 1,024 kWh a month. Across Florida the average bill was $156.09 on 1,104 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 2,499.5 minutes per customer with major event days included and 83.5 minutes with them excluded, calculated under IEEE 1366 standard. The median among Florida utilities reporting was 723.1 minutes with major event days; this utility's figure is 246% above that median.
The average price is up 22.1% on 2019, against up 20.9% for Florida as a whole, and down 7.9% on 2023. EIA's early release for 2025, which has not been fully edited, shows 18.36¢.

Sales by sector, 2024
| Sector | Customers | Sales | Share of sales | Revenue | ¢ per kWh, bundled |
|---|---|---|---|---|---|
| Residential | 1,793,067 | 22 TWh | 54% | $3,665,224,100 | 16.63¢ |
| Commercial | 214,726 | 15.8 TWh | 38% | $1,936,988,400 | 12.26¢ |
| Industrial | 1,671 | 3.3 TWh | 8% | $318,169,200 | 9.68¢ |
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: 46.2 TWh in total, of which 94.4% was its own net generation and 2.4 TWh was bought wholesale; summer peak demand 9,469 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 2.21 interruptions per customer with major event days, 0.96 without; CAIDI 1,133.1 minutes per interruption. EIA's Florida total across all reporting utilities was 1,321.5 minutes with major event days and 66.4 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.
