Who provides electricity in Madison County?
Madison County is split among three investor-owned utilities: Ohio Edison serves the largest share, with AEP Ohio and AES Ohio serving other areas. Three electric cooperatives also serve rural parts of the county. Businesses on an investor-owned utility can choose a PUCO-certified generation supplier; co-op members and municipal-system customers generally cannot. Madison County is in central Ohio, with its county seat in London and 43,824 residents (2020 Census).
| Provider | Type | Can businesses choose a supplier? |
|---|---|---|
| Ohio Edison | Investor-owned distribution utility | Yes |
| AEP Ohio | Investor-owned distribution utility | Yes |
| AES Ohio | Investor-owned distribution utility | Yes |
| Pioneer Electric Cooperative | Electric cooperative | Generally no (member-owned) |
| South Central Power Company | Electric cooperative | Generally no (member-owned) |
| Union Rural Electric Cooperative | Electric cooperative | Generally no (member-owned) |
Utility boundaries follow service-territory maps, not township or city lines, so two buildings a mile apart can have different providers. The utility name on each bill is the final word. What co-op and municipal customers can do instead of shopping is covered in municipal and co-op areas.
AEP Ohio begins operating under the name Ohio Power Company on October 1, 2026 (website OhioPowerCo.com). The utility says rates, service, account numbers and supplier choice don't change.
Default prices for the utilities in Madison County
| Utility | Small-business default generation price | Period |
|---|---|---|
| Ohio Edison | Historical class reference: 9.38¢/kWh, GS rate | June 1, 2026 – May 31, 2027, annual average |
| AEP Ohio | Varies by rate schedule (on your bill); residential reference 10.97¢ | July 1 – Sept 30, 2026 |
| AES Ohio | Varies by rate schedule (on your bill); residential reference 10.86¢ | June 2026 – May 2027 annual average |

Buying for several sites in Madison County
- Split the bid by utility. Suppliers price Ohio Edison, AEP Ohio, and AES Ohio accounts separately, so a single county-wide price isn't realistic.
- Pull out co-op and municipal meters. They generally can't be enrolled with a retail supplier; sending them wastes suppliers' credit reviews and slows quotes.
- Check aggregation status. Accounts at 700,000 kWh a year or less may already be in a community aggregation program; note each account's current supplier and end date.
- Co-term contracts. Aligning end dates lets you re-bid the whole portfolio at once instead of renewing one site at a time.

Decision worksheet: service areas within Madison County
Use a meter schedule rather than one county-wide assumption
Madison County is in central Ohio and its county seat is London. A county portfolio should begin with each legal customer, utility name and service address. Investor-owned utility coverage, municipal systems and cooperative service do not stop neatly at the same administrative boundaries.
There is no separately maintained city guide in this county’s current city inventory. Use the utility named on the actual bill rather than substituting a nearby city’s information.
The existing county inventory identifies cooperative context including Pioneer Electric Cooperative, South Central Power Company, Union Rural Electric Cooperative and municipal context including no separately listed municipal system in this dataset. This is not an exhaustive address-level determination; confirm service directly before enrolling a meter.
Assign responsibilities before a portfolio bid
Give one person ownership of the service-address list, another responsibility for expected operating changes, and a named signer responsibility for contract authority. These roles may be held by one person, but they should not be assumed from who receives the monthly invoice. Tenant, franchise and property-management arrangements deserve a separate authority check.
Keep non-shoppable accounts in the operating-cost review while excluding them from retail-supplier enrollment schedules. For eligible accounts, compare start dates, included supply components, additional fees and site-removal rights. A master agreement is a contractual structure, not a guarantee that every meter receives the same price or automatic savings.
Use the comparison tools without sending financial inputs to the website. The first inquiry needs only business, utility and the decision you want help with. For definitions, consult PUCO’s customer-choice guidance.
