Duke Energy Ohio rates

Duke Energy Ohio has one residential plan modeled here. A typical Ohio home using 866 kWh a month pays about $164 a month.

Ohio has retail choice. Prices on this page are all-in: Duke Energy Ohio’s delivery charges plus its default supply (the rate you pay if you have not chosen a supplier, often called the “price to compare”). If you buy supply from a retail supplier, Duke Energy Ohio still bills delivery and the supplier’s price replaces the supply part, so the supply rate alone is well below the all-in price shown here.

How Duke Energy Ohio’s plans work

RS (Residential Service). In July every kWh costs about 17.8¢, whatever the month's use. Fixed charge: $10.40 a month.

Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.

As a cross-check, Duke Energy Ohio billed its residential customers an average of 15.00¢ per kWh in 2024 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for Ohio’s price change since.
