Current residential rates
Duke Energy Florida residential rates are shown below, from the utility's published tariffs and the public Utility Rate Database. Rates vary by plan, season, and usage and change over time.
| Plan | Energy charge | Fixed / basic |
|---|---|---|
| Residential Service (RS-1) - typical all-in bill (FPSC benchmark, early 2026, before mid-2026 reductions) | ~18.9 c/kWh all-in (FPSC typical bill $189.24 at 1,000 kWh/mo, base + fuel + clause riders) | ~$14/mo customer (basic) charge |
| Residential Service (RS-1) - base energy + customer charge example (utility-rates.com tariff snapshot) | ~14.56 c/kWh energy example (derived bill ~$159.91 at 1,000 kWh) | $14.27/mo customer charge |
| Fuel cost recovery component (residential, 2026) | 4.414 c/kWh Jan-May 2026, reduced to 3.852 c/kWh effective June 2026 billing | n/a (rider component of the bill above) |
Florida is fully regulated, so Duke Energy Florida residential customers are on the standard Residential Service (RS-1) tariff; there are no competitive retail energy plans. The all-in residential price = base energy charge + a monthly customer charge (~$14) + several clause riders (fuel, capacity, environmental, energy-conservation, storm-protection). The FPSC "typical bill" benchmark of $189.24/1,000 kWh (~18.9 c/kWh) reflects early-2026 rates. Duke Energy Florida announced and implemented multiple 2026 reductions: a ~$44/1,000 kWh decrease starting March 2026 and a further fuel-rate cut (4.414 to 3.852 c/kWh) from June 2026, described as roughly a 25% reduction vs January 2026 for a 1,000 kWh user. For a rate-increase calculator, the EIA-861 long-run average price (16.63 c/kWh in 2024) is the most stable per-kWh basis; the ~18.9 c/kWh figure is a current point-in-time all-in benchmark that is being adjusted down through 2026. Exact tariff sheets are filed with the Florida PSC (e.g., docket filings under DUKE ENERGY FLORIDA, 2025) and posted at duke-energy.com rate schedules (jur=FL01); both 403'd to automated fetch, so the customer-charge figure (~$14.27) is from the utility-rates.com tariff snapshot and should be confirmed against the live RS-1 sheet before publishing exact cents.

The falling rate cuts both ways
Duke announced roughly a 25 percent reduction versus January 2026 for a typical 1,000 kWh customer, arriving through a March decrease and a June fuel cut. Cheaper power is good news for your bill and quietly bad news for solar payback estimates that were computed against the old rate. Any quote you got before mid 2026 deserves a rerun with current numbers, and this page's long run averages are the stabler basis for projections than any single point in time.
Full retail netting under Rule 25-6.065
Duke Energy Florida offers traditional, full retail-rate net metering under Florida PSC Rule 25-6.065, which the state has preserved (no successor tariff / no net-billing rollback). Every kWh your rooftop solar exports to the grid offsets a kWh you pull from the grid at the same full retail rate, netted on your monthly bill. If you export more than you use in a given month, the surplus carries over as a kWh credit to the next billing cycle (so summer overproduction can offset winter usage). Any credit still unused at the end of the calendar year is trued up and paid out to you in cash, but at Duke's lower avoided-cost (wholesale) rate under its COG-1 tariff rather than the full retail rate. Practically: size a system to match (not greatly exceed) your annual usage so most exports are credited at full retail; the small year-end surplus is the only portion valued at the lower avoided-cost rate. Residential systems 10 kW or under qualify as Tier 1 with the simplest, no-fee interconnection.
What rising Duke Energy Florida rates could cost you
Duke Energy Florida rates have risen about 3.4% per year. Enter your bill to see what that pace of increase could compound to over time, and what you have likely already absorbed. This is an estimate, not a guarantee.
Estimate only. Projects your current bill forward at Duke Energy Florida's historical average rate increase (3.4% per year, from EIA data); it assumes your usage stays the same except for any add-ons you select. Actual rates depend on your usage, rate plan, and the utility's future filings, and are not guaranteed. This is general information, not financial advice.
Sizing beats spending here
The netting rules here are genuinely favorable: full retail one for one credits under Florida Rule 25-6.065, monthly rollover, and the simplest no fee interconnection for systems 10 kW and under. Summer overproduction can carry winter usage.
The care point is the annual true-up. Credits still unused at calendar year end are paid out in cash at Duke's avoided cost COG-1 rate, far below retail. Size to match your annual usage rather than exceed it, and rerun any payback math against the falling 2026 rates before signing anything.

FAQ
Does Duke Energy Florida offer net metering?
Yes, traditional full retail rate net metering under Florida PSC Rule 25-6.065. Exported kWh offset purchased kWh one for one on the monthly bill, and surpluses roll forward to later months.
What happens to leftover credits at the end of the year?
They are trued up and paid to you in cash, but at Duke's lower avoided cost rate under its COG-1 tariff rather than retail. That is why sizing a system to your annual usage beats oversizing.
Are Duke Florida rates going up or down?
Down through 2026: Duke announced and implemented a decrease starting March 2026 and a further fuel rate cut from June 2026, together described as roughly 25 percent versus January 2026 for a 1,000 kWh customer. The long run average still rose about 3.4 percent per year over the past decade.
What size system avoids fees and paperwork?
Residential systems 10 kW and under qualify as Tier 1, with the simplest no fee interconnection under the Florida rule.
