Duke Energy Florida rates and bills
Duke Energy Florida's 1,819,962 residential customers in Florida paid an average of 18.36¢ per kWh in 2025, for an average bill of $185.26 a month on 1,009 kWh.1 Over the last 12 months (Sep 2025–Aug 2026) the average was 17.12¢, and 15.18¢ in August 2026.2
EIA-861 2025 final (released October 7, 2026) and EIA's monthly utility survey through August 2026 (preliminary); next monthly update expected November 24, 2026. Averages are revenue divided by kWh, all charges included: not the rate printed in a tariff.
32 of 67 Florida counties served (EIA-861 2025)
Duke Energy Florida's homes paid an average of 18.36¢ per kWh in 2025, up 10.4% in a year and the 2nd highest among Florida's 361 utilities with 10,000 or more residential customers. In 2026 it has come down: 15.18¢ per kWh in August 20263, −17.6%2 against the same month of 2025.
Price per kWh: three periods, three figures
EIA reports what Duke Energy Florida's 1,819,9621 residential customers paid in three ways, and they differ because the periods differ:
- Calendar 2025 (EIA-861, final): 18.36¢ per kWh1.
- Last 12 months, September 2025 to August 2026 (EIA-861M, 2026 months preliminary): 17.12¢ per kWh.
- August 20263 alone (preliminary): 15.18¢ per kWh2.
Each is an average price: residential revenue divided by the kilowatt-hours sold. It includes the monthly customer charge, the fuel charge and every other cost-recovery charge on the bill, and excludes most taxes. It is not the energy rate in Duke's tariff, and a household using little electricity pays more per kWh than this average because the fixed charge is spread over fewer kWh.
The 2025 figure put Duke Energy Florida 2nd highest of the 36 Florida utilities with 10,000 or more residential customers, 20.7% above the Florida average (15.21¢ per kWh4, all providers). Only Tri-County Electric Cooperative, a much smaller cooperative, averaged more (18.44¢ per kWh). Nationally it ranked 47th highest of 177 utilities with 100,000 or more residential customers, and was 3.3% above the national average for investor-owned utilities1.
A storm-charge year, then a decline
The annual average rose from 16.63¢ per kWh5 in 2024 to 18.36¢ per kWh1 in 2025. During 2025, Duke Energy Florida's bills carried an interim storm restoration recovery charge for the costs of Hurricanes Debby, Helene and Milton, which the Florida Public Service Commission approved in February 2025 (Order PSC-2025-0061-PCO-EI) for billing from March 2025. The charge ended in early 2026. EIA's monthly figures match that timing: the residential average stepped up in March 2025 and came back down from February 2026.

The latest readings show how far the average has moved. In August 2026, Duke Energy Florida's residential average was 15.18¢ per kWh, −17.6% against August 2025; the Florida average for the same month was 14.99¢ per kWh, −2.2%3 on a year earlier. The 12 months to August 2026 still include the last months of the storm charge, which helps explain why the 12-month figure (17.12¢ per kWh2) sits between the 2025 average and the latest month. A single month is preliminary and seasonal; the next EIA release, on November 24, 2026, adds September 2026.
The commission sets Duke Energy Florida's base rates and reviews its fuel and storm-cost charges in separate proceedings, so the average can change between rate cases. The guide to rate increases explains how those decisions reach a bill.
Duke against Tampa Electric, FPL and the co-ops around it
Duke Energy Florida's counties run from Pinellas and Pasco on the Gulf coast to Orange and Seminole around Orlando, north to Alachua and west to Bay County in the Panhandle, so it shares ground with investor-owned utilities and several electric cooperatives. In 2025 the cooperatives next to it averaged less per kWh: Withlacoochee River Electric Cooperative 13.70¢ per kWh, SECO Energy 14.98¢ per kWh and Clay Electric 14.02¢ per kWh. Tampa Electric averaged 17.32¢ per kWh and Florida Power & Light 14.62¢ per kWh1.

| Clay Electric Cooperative (FL) | 14.02¢ |
| Florida Power & Light (FL) | 14.62¢ |
| SECO Energy (FL) | 14.98¢ |
| Tampa Electric (FL) | 17.32¢ |
| Duke Energy Florida (FL) | 18.36¢ |
Over the last 12 months (September 2025 to August 2026), Tampa Electric's customers paid 18.09¢ per kWh on average, Duke's 17.12¢ per kWh and FPL's 14.81¢ per kWh. In August 20263, against the same month a year earlier, Tampa Electric's average changed by −6.8% and FPL's by +1.0%, against −17.6%2 at Duke.
Nobody chooses among them. Florida has no retail choice (0.0%1 of residential customers bought from a competitive supplier in 2025), and the utility whose lines reach an address is its supplier.
Lower use, still a large bill
Duke Energy Florida's homes used less electricity than the Florida average: 1,009 kWh a month in 2025, against 1,103 kWh for the state, 1,117 kWh at Tampa Electric and 1,248 kWh at Withlacoochee River. The higher price outweighed it. The average bill was $185.26, a change of +8.8%1 from $170.34 in 2024 even though use per home dipped from 1,024 kWh5. The Florida average bill was $167.866. Over the last 12 months (September 2025 to August 2026) Duke's average bill was $173.39 for 1,013 kWh2.

July is the heaviest month
Florida's cooling load ranks the highest among the 48 contiguous states and DC (3,4297 cooling degree days a year, NOAA's 2016 to 2025 average), and Duke Energy Florida's monthly data follow the heat. In the 12 months September 2025 to August 2026, the lightest month was December 2025, at 734 kWh per home and an average bill of $148.06; the heaviest was July 2026, at 1,409 kWh and $213.832.

| August 2026 | 1,325 | $201.06 | 15.18¢ |
The bill swings less than use, because the fixed customer charge is the same in a mild month as in a hot one. Within this window, bills before February 2026 still carried the storm charge, so summer 2026 bills were lower than the same use would have cost a year earlier.
Where Duke Energy Florida serves
EIA's service-territory records place Duke Energy Florida in 32 counties, the spread described above, from Pinellas and Pasco to Orange, Seminole, Alachua and Bay. In 31 of them at least one other utility also reports customers, often a city utility or a cooperative; in 18 county Duke is the only one. A county or ZIP code therefore does not settle which utility serves a home: Duke's own service-area map decides by address. EIA publishes no city prices.

Rooftop solar, smart meters and time-of-use
Rooftop solar is more common on Duke Energy Florida's system than on FPL's or Tampa Electric's: 103,861 residential net-metered installations at the end of 2025, 57.1 per 1,000 residential customers, with 934.5 megawatts of capacity. Tampa Electric had 42.5 per 1,000 and FPL 22.410.
Advanced meters cover 99.9% of residential meters, yet time-based pricing is rare: 2,046 customers, 0.1%10 of the residential total, were on a time-of-use rate in 2025. The time-of-use guide explains how such a rate changes a bill.
Outages
Duke Energy Florida's customers averaged 87 minutes without power in 2025 including major event days, more than the Florida average of 70 minutes, and 82 minutes excluding them, with 0.97 interruptions per customer, measured under IEEE 1366. FPL reported 47 minutes and Tampa Electric 112 minutes11 on the same basis. One hurricane season can move these figures a long way, so a single year is not a trend.
Business customers and the Duke group
Commercial customers paid Duke Energy Florida 13.03¢ per kWh on average in 2025, with an average monthly bill of $794.80, and its 1,575 industrial accounts paid 9.54¢ per kWh. Across all 2,037,985 accounts the average was 15.61¢ per kWh1.
Duke Energy Florida is one of Duke Energy's operating utilities, regulated in Florida only. Its 2025 residential average, 18.36¢ per kWh1, was the highest in the group; the Duke Energy page compares them all, and electricity in Florida covers the state.
Questions and answers
What are Duke Energy Florida's rates per kWh?
Its residential customers paid an average of 18.36¢ per kWh1 in 2025, 17.12¢ per kWh over the last 12 months (September 2025 to August 2026) and 15.18¢ per kWh2 in August 20263; 2026 months are preliminary. Each is total residential revenue divided by kWh sold, so the customer charge, fuel and storm charges are folded in. The energy charge in Duke's tariff is a different, narrower number.
Did Duke Energy Florida rates go up or down in 2026?
Down, so far. The August 20263 average of 15.18¢ per kWh was −17.6%2 against August 2025, after a 10.4%1 rise from 2024 to 2025. The storm restoration charge billed during 2025 ended in early 2026.
What is the average Duke Energy Florida electric bill?
$185.26 a month in 2025 for 1,009 kWh1, and $173.39 over the last 12 months (September 2025 to August 2026). The month of highest use in that period was July 2026, when the average bill was $213.832.
Does Duke Energy Florida have time-of-use rates?
It reported a residential time-of-use program to EIA for 2025, with 2,046 customers enrolled, 0.1%10 of its residential customers. Peak hours and prices are set in its tariff on file with the Florida Public Service Commission.
