Updated
In short
- The default rate is the supply side of your bill, and delivery is billed on top. Duke Energy Ohio still delivers your power, maintains the lines, bills for delivery and responds to emergencies.
- Duke's default supply is bought in competitive auctions that an outside consultant runs, according to Duke's auction site.
- Our data holds 58 Duke Energy Ohio rate periods since January 2022, and the current rate is up 2.8% from 10.20¢ per kWh (October 1 – October 31, 2025), the same period a year earlier.
- Staying on the default rate is a valid choice. A supplier offer has terms to check first: contract length, fees and what happens when the term ends.
How much does Duke Energy Ohio charge per kilowatt?
Duke Energy Ohio prices electricity by the kilowatt-hour (kWh), not by the kilowatt, so its price per kWh is the number to look for. Its default supply rate is 10.49¢ per kWh for October 1 – October 31, 2026.

Kilowatt-hour (kWh). The unit on your bill: one kilowatt of power used for one hour, such as a 100-watt light bulb running for 10 hours.
If you do not choose a supplier and your community does not buy electricity for you as a group, you pay the Standard Service Offer (SSO), PUCO's name for the default generation supply rate. PUCO's chart prints the per-kWh figure for it as the price to compare. PUCO says that is the amount per kWh you no longer pay your utility when you choose a supplier, so it is the number to hold offers against.
Duke says its price to compare includes six riders, among them Rider RTO, its Regional Transmission Organization Rider. Duke's auction site says the suppliers who win its auctions provide energy, capacity and market-based transmission service. Distribution, the local poles and wires, is billed on top whichever supplier you use.

What does the Duke Energy Ohio rate come to for a month of electricity?
For an example home that uses 750 kWh in a month, the supply portion at 10.49¢ per kWh comes to $78.68. This is an example, not your bill. It covers supply only and leaves out delivery charges and taxes.
To try your own usage, multiply the kWh on your bill by the rate, then divide by 100 to turn cents into dollars. This is arithmetic, not a forecast, and it says nothing about any supplier's offer.

Since January 2022, PUCO's chart shows new Duke Energy Ohio periods starting every month.
Duke's own price-to-compare page says the figure can change whenever Duke adjusts one of the six riders listed below. PUCO's chart states the period for each Duke Energy Ohio figure, so go by those dates.
Which Duke Energy Ohio charges stop when you choose a supplier?
Duke defines its price to compare as the annual amount you stop paying Duke when you choose another generation provider, divided by annual kWh. Duke says that amount includes six riders:
- Rider RC, the Retail Capacity Rider
- Rider RE, the Retail Energy Rider
- Rider AER-R, the Alternative Energy Recovery Rider
- Rider RTO, the Regional Transmission Organization Rider
- Rider SCR, the Supplier Cost Reconciliation Rider
- Rider RECON, the Fuel and Reserve Capacity Reconciliation Rider
Duke says the number changes when any of these riders is adjusted, and PUCO's chart gives the dates each figure covers.
Does Duke Energy Ohio publish a price to compare by usage level?
The figure on this page is the one PUCO's chart prints. Duke's own price-to-compare page offers a table of average figures by annual kWh band, and a calculator that uses 12 months of kWh from your bill.
If your account is not on residential Rate RS, Duke says to call or email for a customized price to compare.
Where does Duke Energy Ohio serve?
A 2021 Duke news release says the company serves parts of Adams, Brown, Butler, Clermont, Clinton, Hamilton, Montgomery and Warren counties in southwest Ohio. A county name alone may not settle it, so check your bill for your utility's name.
How is a Duke Energy Ohio bill split between supply and delivery?
PUCO says an Ohio electric bill has three main parts: generation, transmission and distribution. Duke's price to compare gathers the supply side of that bill, and the rest is delivery.
Generation: the supply portion
Duke Energy Ohio buys default supply in competitive auctions. Its auction site says an outside consultant runs a descending-price clock auction for full-requirements supply. Its results page lists products that start delivery on June 1.
Transmission and distribution
Duke's auction site says market-based transmission service is part of the supply its auction winners provide. Distribution is the local poles, wires and meters, and it is billed on top of supply whichever supplier you use.
How does Duke Energy Ohio electric choice work, and should you use it?
Most Duke Energy Ohio customers can choose a certified supplier, and PUCO says the utility keeps delivering your power if they do. A supplier's terms decide whether its offer helps you. For some households, the default rate is still the better fit.
A supplier that PUCO certifies is a Competitive Retail Electric Service (CRES) provider. To compare Duke Energy Ohio power suppliers, put each offer's total price per kWh next to your price to compare. Use the Apples to Apples Duke Energy Ohio chart, PUCO's side-by-side list of offers. Our Apples to Apples guide explains the columns, and Energy Choice Ohio explains the program.
When staying put may be the better choice
- The offers you see are all higher than the price to compare, or lower only until the monthly fee is added.
- You would rather skip contract dates, renewals and early termination fees.
- You take part in the Percentage of Income Payment Plan Plus (PIPP Plus). PUCO says that program cannot use energy choice.
- Your town or county already buys supply for you through governmental aggregation, a group purchase that voters approved, and you did not opt out.
Keep in mind that the default rate is not locked in. As the table above shows, it moves by period, and a fixed offer stays at one price for its term.
The real risks of switching
- Introductory price. Some contracts open with an introductory price for one to three billing cycles. After that the price changes to a fixed or variable one. Variable prices can move by the hour, day or month, so ask what happens next.
- Early termination fee (ETF). A fee you may owe if you leave the contract early. Find out the amount before signing.
- Monthly fee. A supplier may charge a flat fee each month along with its rate. Count it in your total.
- A default rate that resets. The price to compare changes by period, so an offer under it today might not be under it later.
How the switch works
When you enroll, the supplier sends Duke Energy Ohio an electronic enrollment request. The supplier's contract must say when service is expected to start and commit to begin at the next available meter reading. The utility then mails a confirmation notice, and you have seven days from its postmark date to cancel. Ohio's utility rules require the utility to take cancellation calls around the clock.
Duke's choice FAQ says the supplier decides whether its charges appear on Duke's bill or on a separate bill, and that budget billing stays available after you switch. Duke also says a customer whose supplier fails returns to Duke's standard service offer.

Frequently asked questions
How much does Duke Energy Ohio charge per kilowatt?
Duke Energy Ohio charges for electricity by the kilowatt-hour, not the kilowatt. Its default supply rate is 10.49¢ per kWh for October 1 – October 31, 2026, according to the PUCO Energy Choice Ohio chart. Delivery charges are separate, and a supplier's offer replaces only the supply portion.
Which Duke Energy Ohio charges stop when I choose a supplier?
Duke says that when you choose another generation provider you no longer pay it six riders: Retail Capacity, Retail Energy, Alternative Energy Recovery, Regional Transmission Organization, Supplier Cost Reconciliation, and Fuel and Reserve Capacity Reconciliation. Its price to compare is that yearly amount divided by your yearly kWh. Duke still delivers your power and sends bills.
When does the Duke Energy Ohio default rate change next?
The current Duke Energy Ohio period, October 1 – October 31, 2026, ends the day before November 1, 2026, when the next period starts. Your bill shows the price to compare, and the PUCO Energy Choice Ohio chart states the period each rate covers, so check both after a change.

Yes. Duke's own price-to-compare page offers a table of average figures by annual kWh band and a calculator that uses 12 months of kWh from your bill. If your account is not on residential Rate RS, Duke says to call or email for a customized figure. PUCO's chart prints one headline number.
Can I keep budget billing if I choose a supplier at Duke Energy Ohio?
Duke's choice FAQ says budget billing stays available after you switch. If your supplier bills you separately, ask whether it offers a budget plan too, because PUCO's list of questions for suppliers includes one. Check how the supplier's charges and Duke's charges will appear before you enroll.
Which counties does Duke Energy Ohio serve?
A 2021 Duke news release says the company serves parts of Adams, Brown, Butler, Clermont, Clinton, Hamilton, Montgomery and Warren counties in southwest Ohio. A county name alone may not settle it, so check your bill for your utility's name before you compare any rate.
