Duke Energy Florida Electricity Rates in 2026: Why Bills Fell About 25%

Duke Energy Florida rates have one of the most unusual stories of 2026: home bills fell sharply.

Duke said that by June, a typical home using 1,000 kWh a month was paying about $50 less per month than in January. That's a drop of roughly 25%. Part of that cut was permanent for the year, and part of it was temporary and has now ended.

So what does Duke Energy Florida actually charge? The most important fact is that the bill changed a lot during the year. January, March, September and October 2026 aren't the same rate structure. A solar, HVAC or battery analysis built on the wrong month can be badly off.

How Did Duke Energy Florida Rates and Bills Fall About $50?

For a typical customer using 1,000 kWh (kilowatt-hours, the unit on your bill) a month, the reductions came in three steps:

• February: about $33 lower. Duke removed the storm-cost recovery charge for Hurricanes Debby, Helene and Milton a month earlier than planned.
• March: about $11 lower. Duke's seasonal rate structure lowers bills every March through November, when usage is typically higher.
• June through September: about $6 lower. Duke collected more for 2024 storm recovery than the final costs required. The difference was returned through lower fuel charges.

Together, that's roughly $50 a month, or about 25%, compared with January.

What Did the June Change Look Like?

Under a Florida Public Service Commission (PSC) order, the typical 1,000-kWh Duke bill went from about $153.19 in May to $146.89 starting in June. That's a drop of $6.30. The fuel portion fell from about $41.27 to $34.65. A small base-rate increase for a new solar plant offset part of that.

Why Did Storm Charges Disappear So Quickly?

Duke spent about $915 million restoring service after the 2024 hurricanes. It had collected about $1 billion through its storm-recovery charge. Customers only pay actual eligible costs, so the charge came off early. The extra (about $90.5 million) was refunded through lower fuel rates from June through September 2026.

What Changed in October?

The temporary summer refund ended after September. Duke's fuel charge in October 2026 was back at about $41 for a typical 1,000-kWh bill. That's up from about $35 during the summer. So at the same usage, an October bill runs roughly $7 higher than a summer bill did.

Watch for one more seasonal change. Duke's lower seasonal rates run March through November. When they end, December through February bills rise by roughly the same ~$11 they fell in March.

Don't Use January 2026 as Today's Baseline

Suppose a solar proposal was built in January. It assumed the high winter bill would last forever and grow every year. Even after this fall's increase, Duke's typical bill is still well below January's. That could seriously overstate projected savings.

A better approach:

1. Use your current bill and 12 months of usage.
2. Adjust for temporary credits, storm charges and seasonal rates.
3. Use approved future changes where they're known.
4. Model uncertain rate growth conservatively.

Fuel Costs Matter Too

Duke adjusts rates for fuel, purchased power, capacity, environmental compliance, storm protection and conservation programs. Fuel is passed through to customers at cost, not as a source of profit. So lower fuel costs lower bills, and higher fuel costs raise them.

Duke Says Power-Plant Efficiency Has Saved Customers Money

Duke says efficiency improvements at its natural gas plants have produced about $340 million in fuel savings. Duke puts that at about $10 a month for a typical customer. It's separate from the temporary storm-cost changes.

New Utility-Scale Solar Is Also Lowering Fuel Costs

Duke completed the 74.9-MW Jumper Creek solar site in Sumter County in May 2026. It expects the site to save customers about $250 million in fuel over its life. Duke says four new solar sites together should save about $1 billion. It plans about 900 MW of new utility-scale solar by the end of 2028.

That's different from rooftop solar. Utility-scale solar lowers system fuel costs for everyone. Rooftop solar lowers one home's grid purchases. Both matter, in different ways.

What Is Proposed for 2027?

Duke's 2025–2027 rate agreement originally included a 2% base-rate increase for 2027. In July 2026, Duke announced it would avoid that increase. It plans to take about $50 million of tax-credit benefits from its Powerline battery storage project in a single year, instead of spreading them out.

Then on September 3, 2026, Duke asked the PSC for another small change. A typical 1,000-kWh customer would see about a $0.71 monthly decrease from December 2026 to January 2027. As of this writing, that request is still pending PSC review. Duke has requested a 2027 reduction; it hasn't been approved yet.

Duke's 2026 Path Shows Why Rate-Increase Assumptions Matter

A simple proposal might assume electricity prices rise 4–6% every year. Duke's actual recent path looked very different. It included storm charges ending early, seasonal reductions, storm refunds and fuel savings. It also included fuel savings from solar, an avoided 2027 base increase and a requested 2027 reduction. That doesn't mean rates can never rise. It means future rate estimates should be conservative and based on evidence.

What About Data Centers?

Florida's 2026 large-load law also applies to Duke. Customers expected to use 50 MW or more at a single site must pay the full cost of serving them. Protections include minimum demand charges, financial guarantees and early-termination fees. Duke's 2026 home rate changes have been driven by storm recovery, seasonal pricing and fuel, not data centers. The current residential story is downward.

Lower Rates Don't Guarantee a Low Bill

Suppose August 2025 was 1,100 kWh and $175, and August 2026 was 1,700 kWh and $265. It would be easy to say “Duke raised my bill $90.” But usage rose 55%. Meanwhile, Duke's rates were actually lower this summer than in January. The house deserves a look.

If rates fall 25% but your usage rises 50%, your bill can still go up. If usage barely changed but the bill moved, look at storm charges, the fuel adjustment, seasonal rates and approved tariff changes.

In Florida, Start With the AC

Duke names air conditioning as one of the largest energy users in a Florida home. Its summer tips say adjusting the thermostat 7–10°F for eight hours a day can cut cooling costs by up to 10%. That doesn't mean living in a hot house. It means cooling load matters.

Electric Water Heating Is Often Number Two

Duke says the water heater is typically the second-highest energy user in the home. It says setting it to 120°F can save 6–10% on energy costs. Before financing major equipment, find out where your kWh are going.

Duke Offers a Free Home Energy Check

Duke's free Home Energy Check is available online, by phone or in person. It reviews your usage and recommends ways to save. Completing it is the first step toward Duke's Home Improvement Rebate programs. For a high-bill homeowner, it's a logical first step.

EnergyWise Home Bill Credits

Duke's EnergyWise Home program offers up to $141 a year in bill credits. Duke installs a free control device. When demand is high, Duke can briefly cycle equipment such as water heaters, heating and cooling systems and pool pumps. It's a small but easy lever to check before financing a large project.

Duke Has a Time-of-Use Rate

Duke Energy Florida's residential Time-of-Use rate charges more during peak hours and less during discount hours. Under the current tariff:

• Peak hours: 6–9 p.m. on weekdays all year, plus 5–10 a.m. on weekdays from December through February.
• Discount hours: midnight–6 a.m. from March through November, and midnight–3 a.m. from December through February.
• Weekends and major holidays are off-peak.

Households that can shift EV charging, pool pumps, laundry, the dishwasher or water heating out of peak hours may benefit. A home with heavy AC use in the evening has less flexibility. That's why rate analysis and HVAC analysis should happen together. Check the current tariff against your own account before switching.

What About Solar?

Florida's net-metering rules still let qualifying home systems earn kWh credits for extra solar power sent to the grid. Those credits carry forward for up to 12 months. That's fairly favorable compared with states that pay very low rates for exported power.

But a solar model has to start with today's utility rate, not January's. It should also be sized around the efficient future home. Say a home uses 24,000 kWh a year because of an aging AC, leaky ducts and poor insulation. After fixing them, it would use about 18,500 kWh. A system sized around the old number may be bigger than needed. Leave out the old 30% federal solar credit, which doesn't apply to systems installed after 2025.

Battery Storage Has a Different Role

In Florida, a battery's value often comes from hurricane backup: the refrigerator, internet, medical equipment, well pumps, selected cooling and critical circuits. Model that resilience value separately from bill savings.

Four Duke Customers, the Same $225 Bill, Different Answers

• Home A: A 17-year-old AC driving huge summer usage. Best first move: HVAC diagnosis.
• Home B: An efficient home, but the pool pump and EV run during peak hours. Best first move: rate and load-timing analysis.
• Home C: An efficient home with steady high usage and a good roof. Best next move may be solar.
• Home D: Existing solar and strong hurricane-backup concerns. Best next move may be a battery.

The Best Order for a Duke Energy Florida Customer

1. Normalize the rate. Don't use January 2026, or the summer refund months, as your baseline.
2. Compare kWh year over year.
3. Diagnose AC, ducts and insulation.
4. Complete a free Home Energy Check.
5. Check EnergyWise Home for easy annual credits.
6. Evaluate Time-of-Use if you can shift meaningful loads.
7. Evaluate solar using current net-metering rules and your efficient future load.
8. Evaluate a battery separately for resilience.
9. Treat the September 3 rate request as pending until the PSC decides.

The Ashborn Approach

Before recommending equipment, Ashborn Partners looks at your current Duke bill, past kWh use, storm charges and refunds, and seasonal adjustments. We also review HVAC, ductwork, insulation, utility programs and Time-of-Use potential. Then we weigh solar, net metering, battery storage, hurricane resilience and approved vs. proposed rate changes.

When rates fall but the bill stays high, look at the house.

Duke Energy Florida rates can change based on fuel, storm recovery, conservation, environmental and other approved adjustments. The June–September 2026 reduction included a temporary storm-cost refund that ended after September, and Duke’s seasonal rates apply March through November. Duke’s September 3, 2026 request for an additional reduction in January 2027 remains subject to Florida Public Service Commission approval.
