City Aggregation Programs

City of Wilmington- A Guide to Natural Gas and Electric Aggregation Programs

Frequently Asked Questions

What is governmental aggregation?

Governmental aggregation is an easy  and effective way for large groups of consumers to save money on their electric bill.

Ohio Laws allows for cities and counties to form aggregated buying groups to purchase electricity or natural gas on behalf of their citizens. By bringing citizens together, the city/county can negotiate a better price than a person can individually. The city/county chooses the electric or natural gas supplier for all of the customer-members in its group.

How do I sign up?

The aggregation program is an “opt-out”  program. This means you are automatically enrolled unless you choose not to be. This allows as many people as possible to take advantage of the program. This way residents do not miss out on saving because they did not receive notice of the program.

Can I opt out of the program at a later date?


Electric Customers: You may cancel your service with Energy Harbor without penalty and switch to another provider or return back to AES pricing.

Natural Gas Customers: You may terminate your contract with IGS Energy without penalty by calling 877-353-0162. After termination, you will return back to Centerpoint standard pricing.

How much does my gas or electric cost when I’m enrolled?

Electric — Energy Harbor:

April 20, 2022 Press Release City Gas Aggregation Program

 Gas — IGS Energy:
As of October 1, 2022, NYMEX in Ccf + $.162/Ccf then April 1, 2023 to September 30, 2024 $.699/Ccf fixed.

Is it a fixed rate?

Not at first but starting in April. One of the benefits of the current aggregation programs is the price you pay will not increase through the life of the fixed period.


When do aggregation contracts end?

Electric — Energy Harbor

                 Expires December 2025

Natural Gas — IGS Energy

                 Expires September 2024


What happens when the contract ends? Does that mean the aggregation program ends?

No. A few months prior to the end of the contract, the city/county will ask for bids from suppliers for a new rate. They will then enter into a contract with the company who will provide the best price for residents.

I wasn’t automatically signed up for the program. Who should I call if I want to enroll?


Energy Harbor



IGS Energy


Is natural gas and electric aggregation right for me?

To help answer this question, the Ohio Government implemented a website to compare prices from energy suppliers. This empowers residents to make the best, most effective decision.


After I am enrolled in the aggregation program, who sends me a bill?

You will continue to receive your bill from your utility providers  (AES for electric; Centerpoint for natural gas).

For AES/DP&L customers, you will see a line on your bill indicating your electric is being provided by Energy Harbor.

For Centerpoint customers, you will see a line on your bill indicating your natural gas is being provided by IGS Energy.

What if I Live outside  the City Limits?

County resident’s also have access to electric aggregation. If you have specific questions about the County Program, please contact the Clinton County Commissioners Office at (937) 382-2103.

There is no natural gas aggregation program for township residents at this time.
