What does Duke Energy Florida cost at a normal month’s usage?
A household using 1,000 kWh a month pays about $1,791 a year on the cheapest of the 3 plans we can price here — RSL-1 — and $1,869 on the priciest. Same house, same wires.
| A month of | Cheapest, a year | On which plan | Priciest |
|---|---|---|---|
| 500 kWh | $978 | RSL-1 | $1,020 |
| 1,000 kWh | $1,791 | RSL-1 | $1,869 |
| 2,000 kWh | $3,476 | RSL-1 | $3,698 |
The same plan is cheapest at every level of use here, so the answer does not turn on how much you use. Estimates from the filed tariff, priced hour by hour on a household with central air — not a quote.
How much does the plan you pick actually matter here?
Run the same three-bedroom house with central air through every plan Duke Energy Florida, LLC files, and the bill lands anywhere between $1,445 and $1,508 a year. That $63 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.
The plan most households land on by default, RS-1 Residential Service, comes to about $1,472. The cheapest option here, RSL-1, comes to $1,445 — a gap of about $26 a year for a household that never changed a single habit. Whether you can actually capture that depends on when you use power, which is what the calculator below is for.
1 of these 3 plans price by the hour. Those are the ones where moving laundry, dishes, or car charging into the cheap window changes the bill; on the rest, the clock is irrelevant and only the total matters. Which camp you belong in is the first question worth settling, because it decides whether shifting your day is worth anything at all.
How Duke Energy Florida compares across Florida
Run the same three-bedroom house with central air through its default plan at each of the 5 Florida utilities we cover, and Duke Energy Florida is the dearest of the lot at about $1,472 a year; the state median is $1,310. The cheapest, Florida Keys El Coop Assn, charges $906 for identical use — a gap set by the address, not by anything either household did.
The other two households tell the same story in different sizes: a small apartment pays about $841 here against a state median of $784, and the same house with an electric car charging overnight about $1,996 against $1,760. Effective rate, fixed charge included, is 15.6¢ per kilowatt-hour for the family home.
Inside Duke Energy Florida itself, the gap between its cheapest and dearest plan for that house is $63 a year — less than the $566 between Florida's cheapest and dearest utilities. Here the address decides most of the bill; the plan decides the rest.

Same usage, different plan
$70a year
That is the gap between the cheapest plan you could be on — RSL-1 — and the priciest. Not by using less power. By being billed differently for the same power.
| Plan | Per year | Vs best |
|---|---|---|
| RSL-1The hour never matters here — only the season. Rates peak December–February. | $1,676 | — |
| RS-1 Residential ServiceThe hour never matters here — only the season. Rates peak December–February. | $1,703 | +$27 |
| RST-1Peak hits 5am–10am in Dec–Feb, 6pm–9pm in Mar–Nov — every day. | $1,746 | +$70 |
An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
Before you switch anything
- What is a time-of-use electricity rate?
The same kilowatt-hour, priced differently depending on when you use it.
- Should you switch to a time-of-use electricity plan?
A wide peak-to-off-peak gap is a lever, not a saving. Levers need something to move.
