Duke Energy rates in each state it serves

Duke Energy's utilities deliver electricity to 7.5 million homes in 6 states, and their customers' average prices in 2025 ran from 13.41¢ per kWh at Duke Energy Carolinas in North Carolina to 18.36¢ per kWh1 at Duke Energy Florida. In North Carolina and South Carolina, two different Duke utilities, Duke Energy Carolinas and Duke Energy Progress, serve different areas at different prices, so the name on the bill matters.

One company, six state regulators

Duke Energy is a holding company. Its operating utilities, Duke Energy Carolinas, Duke Energy Progress, Duke Energy Florida, Duke Energy Indiana, Duke Energy Ohio and Duke Energy Kentucky, each have their own power plants, costs and rates, set by the utility commission of each state they serve. That is why EIA reports them separately and why each has its own page here, one per state: Duke Energy Carolinas and Duke Energy Progress each serve both North and South Carolina.

Across all of them, bundled residential customers paid 15.35¢ per kWh on average in 2025. That figure, like every price on this page, is average revenue per kWh: everything residential customers paid, fixed charges and riders included, divided by the kWh they used. Duke Energy Carolinas in North Carolina was the lowest at 13.41¢ per kWh, 4.2% below the North Carolina average, with the same company's South Carolina customers next at 13.47¢ per kWh. Duke Energy Florida was the highest at 18.36¢ per kWh, 20.7% above the Florida average and 2nd highest of 361 Florida utilities with 10,000 or more residential customers.

Two Duke utilities in the Carolinas

In North Carolina and South Carolina, the first question is which Duke serves the home. In North Carolina, Duke Energy Carolinas had 1,961,108 residential customers in 2025 and Duke Energy Progress 1,383,941. Their averages were 13.41¢ per kWh and 15.19¢ per kWh: the first 4.2% below the North Carolina average, the second 8.5% above the North Carolina average. In South Carolina the gap was smaller, 13.47¢ per kWh at Duke Energy Carolinas against 14.09¢ per kWh1 at Duke Energy Progress.

County lines do not separate the two. EIA lists Duke Energy Carolinas in 44 North Carolina counties and Duke Energy Progress in 562, and almost all of those counties have more than one utility. The bill, or the utility's own service map, shows which one serves an address; the North Carolina page lists the utilities county by county.

Their seasons differ too. Over the last 12 months (September 2025 to August 2026, 2026 months preliminary), Duke Energy Progress's North Carolina homes had their largest average bill in January 2026, $220.88, while Duke Energy Carolinas's largest came in July 2026, $187.40. Duke Energy Progress in South Carolina, where homes used the most electricity in the group (1,206 kWh1 a month in 2025), had its largest bill in July 2026, $239.343.

Prices moved in opposite directions

From 2024 to 2025, the average residential price fell at all four Carolinas jurisdictions: −3.8% for Duke Energy Carolinas in North Carolina and −3.7% in South Carolina, −2.3% and −5.3% for Duke Energy Progress. In the Midwest it rose steeply: +17.5% at Duke Energy Indiana, from 12.75¢ per kWh4 to 14.98¢ per kWh, and +12.2% for Duke Energy Ohio's default-service customers, against a smaller 3.1% rise at Duke Energy Kentucky; Florida was up 10.4%. Duke Energy Indiana's average bill changed by +23.5%1, the most in the group.

Annual averages hide timing. EIA's monthly survey puts the last 12 months (September 2025 to August 2026) at 16.38¢ per kWh for Duke Energy Progress in North Carolina, well above its 2025 average of 15.19¢ per kWh1, and at 14.00¢ per kWh for Duke Energy Carolinas: in the Carolinas, prices have risen again since the 2025 decline. Duke Energy Florida went the other way. Its last 12 months (17.12¢ per kWh) ran below its 2025 average, and in August 20265 its average of 15.18¢ per kWh was −17.6%3 on the same month a year earlier. EIA's figures combine base rates, fuel and riders into one number, so they do not show which part moved; the guide to rate increases explains how to trace a change through a commission's docket.

Duke Energy Ohio (default service)16.83¢ per kWh17.40¢ per kWh−0.3%
Duke Energy Kentucky13.86¢ per kWh113.85¢ per kWh−14.5%3

The annual column is EIA-861, final; the other two are EIA-861M, preliminary for 2026. A single month moves with weather and billing, so the 12-month column is the steadier guide.

Ohio is different

In Ohio, households can buy their electricity supply from a competitive supplier while Duke Energy Ohio keeps delivering it, and most do: 60.3% of residential customers on its wires bought supply elsewhere in 2025. For them, Duke billed delivery only, averaging 8.17¢ per kWh; their supplier's charge came on top. The 16.83¢ per kWh1 average applies only to customers who stayed on Duke's Standard Service Offer. The Ohio retail choice guide explains the difference. In the other five states, EIA counts Duke's residential customers as full-service: Duke both supplies and delivers their power.

Duke Energy Progress (NC)$158.90
Duke Energy Progress (SC)$169.91
Duke Energy Florida (FL)$185.26

Bills depend on use as much as price. In 2025, the average Duke Energy Progress home in South Carolina used 1,206 kWh a month and paid $169.91, while Duke Energy Kentucky's customers used 926 kWh and paid $128.35, the smallest bill in the group. Duke Energy Florida's average bill, $185.26, was the largest, on 1,009 kWh1 a month: less electricity than the South Carolina Progress homes used, at a higher price.

Florida's homes used the most in summer, peaking in July 2026 at 1,409 kWh, while the Indiana, Ohio and Kentucky utilities all had their highest use in January 2026. Over the 12 months, Duke Energy Kentucky's monthly average bill ran from $86.60 in November 2025 to $174.51 in January 20263.

Meters, time-of-use and rooftop solar

Smart meters are close to universal across Duke: EIA's 2025 data show advanced meters on 99.5% to 99.9% of residential accounts. Few homes use time-varying rates. The largest group was at Duke Energy Progress in North Carolina, 37,024 residential customers (2.7%), followed by 22,6826 at Duke Energy Carolinas there.

Rooftop solar is most common in Florida, with 57.1 net-metered residential systems per 1,000 Duke Energy Florida customers in 2025. The Carolinas utilities ranged from 13.8 to 22.0, and Duke Energy Indiana had the fewest, 5.26.

Outage minutes per customer in 2025, counting major storms, ranged from 87 minutes at Duke Energy Florida to 267 minutes at Duke Energy Indiana. Without major event days the order changed: Duke Energy Carolinas in North Carolina recorded the most, 172 minutes, against 108 minutes at Duke Energy Indiana, so most of Indiana's outage time came on major event days. Duke Energy Carolinas's North Carolina figure including storms, 216 minutes, was more than the North Carolina average of 196 minutes7. All Duke utilities report under IEEE 1366. Each utility page adds its counties, its business prices and the comparison with the other utilities in its state.

Duke Energy rates: common questions

What is Duke Energy's rate per kWh?

Each Duke utility has its own rates. In 2025, residential customers paid an average of 13.41¢ per kWh at Duke Energy Carolinas and 15.19¢ per kWh at Duke Energy Progress in North Carolina, 18.36¢ per kWh at Duke Energy Florida, 14.98¢ per kWh at Duke Energy Indiana and 13.86¢ per kWh1 at Duke Energy Kentucky. Each is total residential revenue divided by kWh, not the energy charge in a tariff.

Why does Duke Energy Progress cost more than Duke Energy Carolinas?

They are separate utilities, Duke Energy Progress, LLC and Duke Energy Carolinas, LLC, each with its own plants, customers and rate cases before the North Carolina Utilities Commission and the Public Service Commission of South Carolina. In North Carolina, Progress customers averaged 15.19¢ per kWh in 2025 against 13.41¢ per kWh1 for Carolinas customers. A home cannot pick between them; the address decides.

Did Duke Energy raise rates in 2026?

It differs by utility. On EIA's preliminary monthly data, the August 20265 residential average was +8.6% against the same month a year earlier at Duke Energy Indiana and +8.2% at Duke Energy Progress in South Carolina, but −17.6% at Duke Energy Florida and −14.5%3 at Duke Energy Kentucky. Rate changes themselves are decided by each state's commission.
