Electric aggregation in Hamilton County, Ohio

Does Hamilton County, Ohio have electric aggregation?

Electric aggregation. A community buys electricity supply for its residents as one group, and in an opt-out program households are enrolled unless they opt out.

Two of the 25 rows for Hamilton County are verified. The other 23 appear in the table by name and date only.

The rows cover eight cities, eight villages and nine townships. Pages exist for the verified places: Cincinnati and Green Township.

A listing stands for one community's program, or for one that covers the whole county. "Verified" means the row is at medium confidence or higher in our registry. For every other row we show a name and a date, because we cannot yet stand behind a supplier or a rate.

Who runs a county-wide program in Hamilton County?

We have no county-level program on record for Hamilton County. The programs in the table belong to the communities named there.

A county program covers only the unincorporated area of Hamilton County, as Ohio Revised Code 4928.20 puts it. The commissioners may join another city, village, township or county in one program. The same section leaves out customers of a municipal electric utility and of a nonprofit electric supplier.

What default electric rate should you check in Hamilton County?

Price to compare. The utility's default supply rate, the one you pay if you have not chosen a supplier or joined a program.

Duke Energy Ohio is the utility our registry records for the Hamilton County rows.

Duke Energy Ohio's price to compare is 10.49¢ per kWh for October 1 – October 31, 2026, according to PUCO's chart. The next period starts November 1, 2026.

Our Duke Energy Ohio electric rates page and price to compare page cover it, and PUCO's chart shows the offers. County lines do not always match territory lines, so check your bill.

Our ZIP list shows 78 ZIP codes in Hamilton County. Postal names such as Addyston, Camp Dennison, Cleves, Harrison, Hooven and three more match no row in this county's file, but a postal name is not a city limit, and a missing row does not mean there is no program.

What if you sign with a supplier in Hamilton County?

PUCO's guidance (PUCO) is that a customer who does not opt out and then picks a new supplier stays in the program, and that keeping a supplier you chose means opting out. Before you sign or return a notice in Hamilton County, ask the program and the supplier how your account will be handled. Read any contract for an early termination fee (ETF).

Staying in the program, or on the utility's default, can be the better choice when every fixed offer on PUCO's chart sits above the rate you pay now for the same dates. A supplier's monthly fee or an ETF can erase the gap too.

PUCO also keeps an electric Do Not Aggregate list for people who want out of future opt-out programs. PUCO says it does not take you out of a program that has already enrolled you.
