Tiffin Business Electricity: AEP Ohio Rates & Choice
Electric utility: AEP Ohio · Seneca County
Who supplies electricity to businesses in Tiffin?
Most businesses in Tiffin (Seneca County) are served by AEP Ohio, a subsidiary of American Electric Power (AEP). Because Tiffin is in AEP Ohio's territory, a business can buy the generation part of its electricity from any supplier certified by the Public Utilities Commission of Ohio (PUCO), while AEP Ohio keeps delivering the power, reading the meter and restoring outages.
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.

Tiffin's business base
Tiffin had 17,953 residents in the 2020 Census and the county seat. Seneca County seat; college town with manufacturing. Large employers and institutions include Heidelberg University, Tiffin University, Mercy Health - Tiffin Hospital, and National Machinery LLC. Hospitals, campuses and plants tend to buy through structured bids with interval data, while offices, shops and restaurants usually fall under Ohio's 700,000 kWh-a-year “mercantile” line and buy standard small-business products.
The price to beat on AEP Ohio
AEP Ohio does not publish one small-business price to compare — it depends on your rate schedule (GS-1 / GS-2) and appears on your bill. For reference, PUCO's residential price to compare for AEP Ohio was 10.97¢/kWh for July 1 – Sept 30, 2026; business figures differ.
That default — PUCO calls it the price to compare — is what a Tiffin 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. AEP Ohio's latest rate-case status: PUCO approved a settlement on April 1, 2026: base distribution revenue +$11 million (AEP asked for $97 million), offset by a roughly $105 million tax refund over 18 months, for a net annual revenue decrease of about $58.7 million. AEP Ohio is also moving to a three-part bill (distribution, transmission, generation) starting in fall 2026.
Is Tiffin in a community aggregation program?
Tiffin is listed among NOPEC's 240-plus member communities. NOPEC runs opt-out electric and natural-gas aggregation; for electricity, NextEra Energy Services became the supplier with June 2026 meter reads on a three-year term. Check your bill to see whether your electric account is enrolled.
Opt-out aggregation automatically enrolls small accounts (700,000 kWh a year or less) that haven't chosen a supplier; accounts already under contract are excluded and larger “mercantile” accounts join only if they opt in. If your Tiffin bill names an aggregation supplier you never picked, that is why. You can leave for a commercial offer priced on your own usage — compare the aggregation price with it first. How aggregation interacts with a business contract is covered in governmental aggregation for Ohio businesses.
Tiffin's neighbors and multi-site buying
If you run locations in more than one town, price them by utility. The nearest cities covered on this site:
| City | Distance | Electric utility |
|---|---|---|
| Fostoria | 12 miles | AEP Ohio |
| Fremont | 16 miles | AEP Ohio |
| Bucyrus | 24 miles | AEP Ohio |
| Findlay | 25 miles | AEP Ohio |
| Bowling Green | 30 miles | Bowling Green Municipal Utilities — municipal, cannot shop |
Nearby sites fall under Bowling Green Municipal Utilities as well as AEP Ohio, so expect a separate price per utility even from one supplier — and leave municipal-utility sites out of the bid.
Switching suppliers in Tiffin
Send 12 months of AEP Ohio bills (interval data for larger sites), the account numbers and the legal name on the account, plus any current supplier's end date. Ask every bidder to show capacity and broker compensation as separate lines (how broker fees work), and compare each offer with AEP Ohio's default price on the same usage. AEP Ohio requires a supplier to submit your enrollment at least 12 days before your next scheduled meter read; the switch then takes effect on that read. Step-by-step detail is in our AEP Ohio guide.

Decision worksheet: a business site in Tiffin
Resolve the account before the price
For an account whose bill names AEP Ohio, check its actual business rate class and current supply arrangement. A nearby municipal or cooperative account can have different options. Start with the delivery company, legal customer and service address; a city name cannot establish those details.
The useful county-level comparison is Seneca County. Other city guides from that county include Fostoria. Those links describe related service-area questions, not a promise that every address shares one provider.
Three different decisions can sit behind one bill question
| Your Tiffin 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 AEP 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.
