The investor-owned utility in Hamilton County is Duke Energy Ohio. One electric cooperative also serves 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.

| Provider | Type | Can businesses choose a supplier? |
|---|---|---|
| Duke Energy Ohio | Investor-owned distribution utility | Yes |
| Butler 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.
Default prices for the utilities in Hamilton County
| Utility | Small-business default generation price | Period |

Buying for several sites in Hamilton County
- One utility, one price structure. Every shoppable site in the county is on Duke Energy Ohio, which keeps portfolio pricing simple.
- 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 Hamilton County
Use a meter schedule rather than one county-wide assumption
Hamilton County is in southwest Ohio and its county seat is Cincinnati. 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 |
|---|---|---|
| Cincinnati | Duke Energy Ohio | Confirm the delivery utility at the actual meter |
The existing county inventory identifies cooperative context including Butler 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.
