Who provides electricity in Montgomery County?
Montgomery County is split among two investor-owned utilities: AES Ohio serves the largest share, with Duke Energy Ohio serving other areas. Two 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. Montgomery County is in southwest Ohio, with its county seat in Dayton and 537,309 residents (2020 Census).
| Provider | Type | Can businesses choose a supplier? |
|---|---|---|
| AES Ohio | Investor-owned distribution utility | Yes |
| Duke Energy Ohio | Investor-owned distribution utility | Yes |
| Butler Rural Electric Cooperative | Electric cooperative | Generally no (member-owned) |
| Pioneer 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 Montgomery County
| Utility | Small-business default generation price | Period |
|---|---|---|
| AES Ohio | Varies by rate schedule (on your bill); residential reference 10.86¢ | June 2026 – May 2027 annual average |
| Duke Energy Ohio | Historical class reference: 11.36¢/kWh, DM (first 2,800 kWh) rate | effective June 1, 2026 |
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 Montgomery County
- Split the bid by utility. Suppliers price AES Ohio and Duke Energy 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 Montgomery County
Use a meter schedule rather than one county-wide assumption
Montgomery County is in southwest Ohio and its county seat is Dayton. 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 |
|---|---|---|
| Centerville | AES Ohio | Confirm the delivery utility at the actual meter |
| Dayton | AES Ohio | Confirm the delivery utility at the actual meter |
| Huber Heights | AES Ohio | Confirm the delivery utility at the actual meter |
| Kettering | AES Ohio | Confirm the delivery utility at the actual meter |
| Riverside | AES Ohio | Confirm the delivery utility at the actual meter |
| Trotwood | AES Ohio | Confirm the delivery utility at the actual meter |
The existing county inventory identifies cooperative context including Butler Rural Electric Cooperative, Pioneer 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.
