Who provides electricity in Knox County?
Knox County is split among two investor-owned utilities: AEP Ohio serves the largest share, with Ohio Edison serving other areas. Four 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. Knox County is in central Ohio, with its county seat in Mount Vernon and 62,721 residents (2020 Census).
| Provider | Type | Can businesses choose a supplier? |
|---|---|---|
| AEP Ohio | Investor-owned distribution utility | Yes |
| Ohio Edison | Investor-owned distribution utility | Yes |
| Consolidated Cooperative | Electric cooperative | Generally no (member-owned) |
| Holmes-Wayne Electric Cooperative | Electric cooperative | Generally no (member-owned) |
| The Energy Cooperative (Licking Rural Electrification) | Electric cooperative | Generally no (member-owned) |
| The Frontier Power Company | 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 Knox County
| Utility | Small-business default generation price | Period |
|---|---|---|
| AEP Ohio | Varies by rate schedule (on your bill); residential reference 10.97¢ | July 1 – Sept 30, 2026 |
| Ohio Edison | Historical class reference: 9.38¢/kWh, GS rate | June 1, 2026 – May 31, 2027, annual average |
All of these utilities sit in PJM, where the capacity price that feeds into generation costs is $329.17/MW-day for June 2026–May 2027 and $333.44 for 2027/28, versus $28.92 in 2024/25.
Buying for several sites in Knox County
- Split the bid by utility. Suppliers price AEP Ohio and Ohio Edison 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 Knox County
Use a meter schedule rather than one county-wide assumption
Knox County is in central Ohio and its county seat is Mount Vernon. 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.
| Local guide | Starting utility context | Enrollment check |
|---|---|---|
| Mount Vernon | AEP Ohio | Confirm the delivery utility at the actual meter |
The existing county inventory identifies cooperative context including Consolidated Cooperative, Holmes-Wayne Electric Cooperative, The Energy Cooperative (Licking Rural Electrification), The Frontier Power Company 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.
