Does Cincinnati have an electric aggregation program?

Ohio lets a city, township or county pool its residents' electricity into one aggregation purchase. Automatic enrollment needs a yes vote from local voters first, and then each household gets a notice and the right to opt out (Ohio Revised Code 4928.20).

Cincinnati's program is City of Cincinnati Electric Aggregation Program. Our registry, researched September 9, 2026 at high confidence, lists Dynegy Energy Services as the supplier at a fixed rate of 10.44¢ per kWh.

The registry records the program's contract term as May 2026 to June 2028. A program can reset its rate inside that term, so your latest notice shows how long the rate above lasts. The registry's exit-fee note reads “No cancellation fee; customers may leave the program at any time (City of Cincinnati OES)”.

Our registry records no county-wide program for Hamilton County.
