Why a Duke Energy Ohio bill moved
The price change was the larger piece
Hold a Duke Energy Ohio household to the filing average and the monthly delivery only bill changed +7.8% between those two EIA years. Holding the 2024 price fixed, the usage change of +2.9% is worth $2.05 a month. The price change of +4.7%, from 7.81¢ to 8.17¢, is worth $3.39 on 2025 usage.
Below the Ohio average
8.17¢ per kWh is below Ohio's 2025 residential average of 16.90¢. July 2026 in the state was 19.45¢, versus 17.38¢ a year earlier (+11.9%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 930 kWh will not land on $76.03.
Two residential prices, on purpose
Duke Energy Ohio reported more than one residential service with a real customer count: 277,897 full service customers at 16.83¢; 422,368 delivery only customers at 8.17¢. Bundled customers buy supply and delivery together. Delivery customers buy supply from someone else. A single blended rate would describe neither bill.
Season
The 2025 monthly average for this Duke Energy Ohio service was 930 kWh, and the Ohio residential average was 874 kWh. A single month can sit far from either figure. Compare kilowatt-hours with the same month last year before you treat the whole increase as a rate hike.
Time-of-use is already on the EIA schedule
EIA's 2025 dynamic-pricing file shows residential time-of-use activity at Duke Energy Ohio, with 28 residential customers enrolled in dynamic pricing. The expensive window is in the tariff, not in that enrollment count. Shifting a dishwasher or an EV charger only helps if you are actually on that schedule.

How to lower the bill
- Read the kilowatt-hours against this filing's average of 930 kWh a month. If your use is the thing that moved, the dollar total can rise on an unchanged rate.
- Add the supply line and the delivery line before you decide the bill is high. This page keeps those EIA rows apart so they are not blended.
- Match this month's weather to last year's same month. A mild comparison month makes an ordinary bill look like a hike.
- Start with LIHEAP for Ohio (https://www.acf.hhs.gov/ocs/map/liheap-map-state-and-territory-contact-listing). A Duke Energy Ohio discount beyond that program needs verification.
- 28 residential customers were already on a dynamic price in the 2025 EIA file. If you are one of them, the window on the tariff is the lever. If you are not, calling the utility to discuss the schedule is the first step, not shifting load you are not being charged extra for.
- If the read is marked estimated, the next actual read can true the account up or down. The tariff rule for that true-up needs verification.

Holding the 2024 price fixed, the usage change accounts for $4.06 a month. The price change, applied to 2025 usage, accounts for $16.72.
What was Duke Energy Ohio's average residential rate?
Using 2025 EIA-861 revenue and sales, the delivery only average was 8.17¢ per kWh. Average use was 930 kWh a month and the average bill was $76.03. This folds in whatever customer charges and riders the utility reported. It is not the marginal rate on your tariff.
Did Duke Energy Ohio raise rates?
The delivery only average price changed +4.7% from 2024 to 2025, from 7.81¢ to 8.17¢. That is average revenue per kilowatt-hour, not a commission order. No 2025–2026 order for this utility was retrieved for this page. A separate rider can still move a single month.
What bill assistance can Duke Energy Ohio customers ask about?
LIHEAP is the federal program for home energy bills (https://www.acf.hhs.gov/ocs/programs/liheap). Duke Energy Ohio may also offer an income-qualified discount, budget billing, or a medical baseline. The current offer, income cutoff, and how to apply need verification on the utility site and with the state LIHEAP office and Public Utilities Commission of Ohio.
Are data centers why this bill went up?
Large computing load is raising U.S. electricity demand, and regulators can later recover new generation and wires costs from customers. EIA has not published a dollar line that isolates data centers on this utility's residential bill. That pass-through needs verification.
