The rate on the record
Investor-owned base rates are usually set in a state docket. Riders can change outside a full rate case. Average revenue per kilowatt-hour is total residential revenue divided by residential sales. It is not a tariff schedule.

Why a Duke Energy Florida bill moved
Usage and price pulled in opposite directions
Hold a Duke Energy Florida household to the filing average and the monthly full service bill changed +8.8% between those two EIA years. Holding the 2024 price fixed, the usage change of −1.5% is worth −$2.59 a month. The price change of +10.4%, from 16.63¢ to 18.36¢, is worth $17.49 on 2025 usage.
Above the Florida average
18.36¢ per kWh is above Florida's 2025 residential average of 15.21¢. July 2026 in the state was 15.03¢, versus 15.11¢ a year earlier (−0.5%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 1,009 kWh will not land on $185.26.
One full-service average
1,819,962 residential customers were on Duke Energy Florida full service in 2025, at 18.36¢ per kWh. That average folds in the customer charge and whatever riders the utility booked as residential revenue. It is not the last block on a tiered tariff.
2024 settlement sets 2025–2027 base rates, with a storm surcharge on top
Florida Public Service Commission, Docket 20240025-EI. Duke told the Florida PSC, in an October 2025 filing, that the commission approved a settlement on August 21, 2024, effective January 2025 through December 2027. Over that term Duke Energy Florida increases base rates by $203 million in 2025 and $59 million in 2026. The return-on-equity band is 9.3 to 11.3 percent,… The rate-case section has the full citation.
Season
Duke Energy Florida customers in Florida average 1,009 kWh a month across the whole year, against a statewide residential average of 1,103 kWh. Summer afternoons do not look like that average. An air conditioner, a pool pump, or a hotter month can move the bill before any rider does.
Time-of-use is already on the EIA schedule
EIA's 2025 dynamic-pricing file shows residential time-of-use activity at Duke Energy Florida, with 2,046 residential customers enrolled in dynamic pricing. The expensive window is in the tariff, not in that enrollment count. Shifting a dishwasher or an EV charger only helps if you are actually on that schedule.

2024 settlement sets 2025–2027 base rates, with a storm surcharge on top
Duke told the Florida PSC, in an October 2025 filing, that the commission approved a settlement on August 21, 2024, effective January 2025 through December 2027. Over that term Duke Energy Florida increases base rates by $203 million in 2025 and $59 million in 2026. The return-on-equity band is 9.3 to 11.3 percent, midpoint 10.3 percent. The same filing says approved interim storm recovery is $1.09 billion and the monthly bill impact is $32.40 per 1,000 kWh for 12 months, March 2025 through February 2026.
Duke's own August 21, 2024 news release said a typical 1,000 kWh bill was projected about $8.26 lower in January 2025 than in December 2024, about 5 percent, because fuel under-recovery, earlier storm costs, and some purchased-power contracts were rolling off as the settlement began. That January comparison is the company's projection, not the storm surcharge.

How to lower the bill
- Read the kilowatt-hours against this filing's average of 1,009 kWh a month. If your use is the thing that moved, the dollar total can rise on an unchanged rate.
- On the statement, separate the base energy charge from fuel or rider lines. A rider can move the total in a month when no new base-rate order exists.
- In Florida, the expensive hours are late afternoon and early evening in summer. Raise the cooling setpoint when you are out, and run the dryer, the dishwasher, and any pool pump outside those hours if your tariff charges more then.
- Start with LIHEAP for Florida (https://www.acf.hhs.gov/ocs/map/liheap-map-state-and-territory-contact-listing). A Duke Energy Florida discount beyond that program needs verification.
- 2,046 residential customers were already on a dynamic price in the 2025 EIA file. If you are one of them, the window on the tariff is the lever. If you are not, calling the utility to discuss the schedule is the first step, not shifting load you are not being charged extra for.
- If the read is marked estimated, the next actual read can true the account up or down. The tariff rule for that true-up needs verification.

LIHEAP is the federal program for home energy bills (https://www.acf.hhs.gov/ocs/programs/liheap). Duke Energy Florida may also offer an income-qualified discount, budget billing, or a medical baseline. The current offer, income cutoff, and how to apply need verification on the utility site and with the state LIHEAP office and Florida Public Service Commission.
Are data centers why this bill went up?
Large computing load is raising U.S. electricity demand, and regulators can later recover new generation and wires costs from customers. EIA has not published a dollar line that isolates data centers on this utility's residential bill. That pass-through needs verification.
