Middletown's business base

Large employers and institutions include Cleveland-Cliffs (Middletown Works), Atrium Medical Center, and Miami University Middletown.

The price to beat on Duke Energy Ohio
Duke Energy Ohio's default generation price for small businesses on the DM (first 2,800 kWh) rate is about 11.36¢/kWh (effective June 1, 2026), up from about 10.59¢ the year before.
That default — PUCO calls it the price to compare — is what a Middletown business pays for generation if it never signs with a supplier. A supplier offer only helps if its all-in generation price, including capacity and any broker fee, beats it on your usage. Statewide, EIA data show the average all-in commercial price rose to about 13.78¢/kWh in the first half of 2026 from 11.07¢ a year earlier, mostly because PJM capacity prices jumped from $28.92 to $329.17 per MW-day.
The delivery utility remains responsible for the wires. Tariff charges can change over time; confirm which transmission and other components are included in a supply offer. Duke Energy Ohio's latest rate-case status: Duke Energy Ohio filed a distribution rate case in March 2026 (Case 26-0132-EL-AIR) seeking about a 3% increase for non-residential customers, which would take effect around May 2027.

Resolve the account before the price
For an account whose bill names Duke Energy Ohio, check its actual business rate class and current supply arrangement. A nearby municipal or cooperative account can have different options.

Three different decisions can sit behind one bill question
| Your Middletown situation | First document to check | Appropriate next step |
|---|---|---|
| Existing supplier agreement is ending | Signed renewal/termination clause and last complete bill | Use the renewal planner, then confirm the actual contractual notice dates |
| Building operation or ownership is changing | Lease/ownership responsibility and the expected load change | Ask about assignment, add/delete rights and volume tolerances before quoting |
| Bill is higher but operations look unchanged | Comparable kWh, demand and charge components for the same period | Separate price, usage and demand effects rather than assuming a supply switch fixes everything |
For this local review, the Duke Energy Ohio guide explains the supply-versus-delivery distinction. Keep tax, banking and account identifiers out of the first inquiry. A discussion can establish whether any private document exchange is needed.
