Village of Mariemont

Electric Aggregation Renewal Status

The Village has signed an agreement with Dynegy to be the next electric aggregation supplier starting with the September 2025 bill and expiring on the August 2026 bill.

The new rate will be 9.657¢ per kWh. This rate may seem high compared to current rates, but Duke will be 10.45¢ per kWh starting in June 2025.

Opt out letters to those currently on the program or those currently with Duke’s default supply will be mailed in July.

We’ll update the table below as we get closer to the new program.

Already with a Third-Party Supplier (Duke Customers)?

If you are already with a third-party supplier, you need to drop with your current supplier before you can join the aggregation program. Duke needs to see a pending drop from your current supplier before they will accept an enrollment from the aggregation supplier. You can call your current supplier (their information is usually on Page 3 or 4 of the Duke bill in the right column) or Duke to drop from your current supplier. Make sure you understand if you have any termination fees before dropping from your current supplier.

Misleading Sales Tactics?

Door-to-door solicitors are everywhere and the phone calls to buy energy seem to never end. Don’t be fooled by these offers. The supplier of the aggregation will never come to your door! Some salespeople may display a solicitor’s permit or official looking badge. THE PERMIT IS NOT AN ENDORSEMENT BY THE COMMUNITY, and the badge may be misleading. They may claim they work with the utility or XYZ Energy company and offer rates far below anything you presently are receiving. Please do not show them your energy bill.  Also, beware of robo-calls and phone solicitors claiming that “your utility account has been flagged for review.” This could also a scam by an unethical broker or supplier designed to mislead you.

If you have questions, don’t hesitate to close the door on the solicitor and call your local officials.
