Cincinnati Electric Choice: How to Compare Duke Energy Ohio Supplier Rates
If you live or run a small business in Greater Cincinnati, your lights still come through Duke Energy¹—but the company that generates (or buys) the electricity on your bill may not be Duke at all. Ohio lets most investor-owned utility customers shop for competitive retail electric supply while the local utility keeps delivering power over the poles and wires. That split is the whole game in Cincinnati electric choice: compare supplier rates against Duke’s default supply price, then decide whether switching is worth the contract risk.
This guide walks through how choice works in Duke Energy Ohio territory, how to use the state’s official comparison tools, what to watch on contracts, and when staying on the utility standard offer is the smarter move.
Why Cincinnati electric shoppers care about choice
Ohio’s average retail electricity price was 11.29 cents per kilowatt-hour in 2024², ranking the state near the middle of the pack nationally. That statewide average mixes homes, businesses, and industrial load, so it is not your personal Duke bill—but it shows why shoppers care about every tenth of a cent on a high-use month.
Ohio’s retail market is unusually tilted toward competitive supply. In 2024, energy-only provider sales in Ohio totaled about 115.5 million megawatt-hours², more than full-service utility sales in the state. In plain English: a large share of Ohio kilowatt-hours already move through competitive suppliers rather than bundled utility default service.
For Cincinnati households, the practical question is narrower. You want to know whether a PUCO-certified supplier can beat Duke Energy Ohio’s default generation price after fees, term length, and renewal rules—and whether the offer still looks good after you read the fine print.
How Ohio electric choice actually works
For most of the twentieth century, one regulated company handled both generation and delivery. The Public Utilities Commission of Ohio (PUCO)³ set rates that let utilities recover costs plus an allowed return. Ohio later opened generation supply to competition so residential customers could shop the way large industrial buyers already did.
Under choice, you pick who supplies the generation of your electricity. Your local utility continues to deliver that power, maintain poles and wires, and restore outages. Energy Choice Ohio³ puts it plainly: if you choose a new supplier, the utility still delivers the electricity and still handles repairs, and you should still call the utility when the power goes out. PUCO continues to oversee safety and reliability of delivery service.
Competitive suppliers in this market are called Competitive Retail Electric Service (CRES) providers—PUCO-certified companies that offer alternative prices, renewable options, or other incentives, according to the state’s glossary of terms⁴. Aggregation groups can also buy for members once they are certified.
Participation is already widespread. Energy Choice Ohio reports that nearly 2.4 million electric customers³ in Ohio participate either individually or through aggregation. Choice is an opportunity, not a mandate: if you never shop, you keep reliable service through your local distribution company.
Wholesale power across Ohio also sits inside a larger grid operator footprint. PJM Interconnection⁵ coordinates wholesale electricity movement in all or parts of 13 states and the District of Columbia. Retail shoppers do not buy directly from PJM; the RTO’s job is coordinating wholesale movement and reliability across its footprint, which is the regional backdrop behind Ohio’s retail supply market.
Reading a Duke Energy Ohio bill and finding the Price to Compare
A Cincinnati electric bill is usually two stories on one page: regulated delivery charges from Duke Energy Ohio, and a generation (supply) charge from either Duke’s default service or a competitive supplier.
The Office of the Ohio Consumers’ Counsel (OCC) explains the split clearly: you do not choose the monopoly utility that owns the wires, but you can choose the supplier of the electricity you use—or stay on the utility’s default market-based rate, called the standard service offer for electric⁶. OCC notes that electric choice is available to customers of AEP Ohio, AES Ohio, Duke Energy, and the FirstEnergy utilities.
Before you compare ads or door-to-door pitches, find the Price to Compare on your Duke bill. PUCO’s switching guide says to find your Price to Compare and use it against offers on Apples to Apples⁷. Because that figure can vary month to month, the same page recommends reviewing several recent bills to understand your average.
OCC’s electric-bill guide points Cincinnati customers to Duke’s sample bill materials and customer line at 1-800-544-6900⁸, and notes that regulated utilities also offer budget billing plans that smooth seasonal spikes. Budget billing does not change the underlying rate math forever—it spreads payments—so ask any marketer how budget billing interacts with their supply product before you switch.
If you already take Duke delivery, keep treating the utility as your outage and wires contact even after a supplier switch. That division of labor is the core consumer-protection feature of Ohio choice.
Comparing Duke-territory supplier rates on Apples to Apples
Ohio’s official shopping board is the PUCO Apples to Apples⁹ chart. Energy Choice Ohio calls it an apples-to-apples comparison of providers—prices, contract terms, and other plan differences in one place.
For residential shoppers in Cincinnati, open the electric category and select Duke Energy Ohio¹⁰ as the service provider. Small-business customers will see Duke DS and DM rate classes on the same portal and should match the tariff code on their bill.
Read the disclaimer on that page carefully. PUCO says the charts are a snapshot of current offers from certified suppliers and aggregators actively enrolling new customers; offers populate in random order; suppliers are responsible for accuracy; and offers can change at any time. PIPP Plus customers are not eligible to enroll with an alternate supplier. If you leave a current competitive contract early, you may owe an early termination fee.
That last point is why “compare Duke supplier rates” is not the same as chasing the lowest teaser number on a flyer. OCC advises electric shoppers to compare a marketer’s rate with the utility Price to Compare⁶, then also compare marketers against one another and against any local government aggregation. OCC also warns consumers to avoid look-alike websites and confirm they are on the official state site ending in .gov—energychoice.ohio.gov⁹.
PUCO’s “why switch” page is refreshingly honest about motives: people shop for savings, for fixed-rate certainty, or for renewable products—and you are under no obligation to switch¹¹. Even a no-switch decision is stronger if you have looked at current offers.
Fixed rates, variable rates, and contract traps
A low cents-per-kWh headline is only useful if you know what kind of price it is. PUCO’s glossary defines a fixed price⁴ as an all-inclusive per-kWh price that remains the same for a set period. Variable products can move with market conditions or supplier formulas. Before you sign, PUCO’s supplier questionnaire¹² tells you to ask whether the price is fixed or changes, how it changes, whether it depends on how much or when you use electricity, whether there is a switching fee or early cancellation fee, how long the rate lasts, and what happens when the contract expires—including whether you get one bill or two.
OCC is more blunt about risk. Its wise-choices fact sheet says savings are not guaranteed⁶ and flags three recurring traps:
- Teaser rates that start low and then jump.
- Evergreen (automatic renewal) contracts that can renew at much higher prices if you miss the end date.
- Early termination fees that make leaving expensive even when a better option appears.
OCC also notes that utility standard offers are based on competitive auctions and have often provided economical prices over time—so whenever the standard offer changes, customers already on a marketer may want to re-check whether returning to the utility still wins. Keep a calendar reminder before renewal, ask what the renewal rate would be, and compare it again to the Price to Compare and Apples to Apples.
If someone pitches “green” power, OCC’s advice is to compare prices carefully and watch for greenwashing—marketing that over-promises environmental attributes while overcharging on price.
Government aggregation as a third path
Shopping solo is not the only path in Duke territory. An aggregator brings customers together so a larger buying group can seek better terms or extra services. Ohio law also allows cities, townships, or counties to run government aggregation¹³ with opt-in or opt-out rules. All aggregators must be PUCO-certified.
Opt-in programs require residents to sign up individually after the local government passes a resolution, develops a plan, holds two public hearings, and gets certified. Opt-out programs need voter authorization, a plan of operation, at least two public hearings, and notice to each consumer that they will be enrolled unless they elect not to participate. For electric aggregation, Ohio’s Energy Choice site says consumers get an opt-out opportunity every three years without a switching fee¹³.
OCC adds a practical shopping rule: most Ohio government aggregation is opt-out, and residents should compare aggregation rates and terms with the standard offer and with marketer offers⁶ before assuming the city deal is automatically best. If you want to stay on utility supply inside an opt-out community, you typically must opt out of the aggregation and switch (or remain) with the utility’s standard offer process.
PIPP Plus customers are ineligible for aggregation, and customers already under individual supplier contracts generally will not appear on opt-out lists—though Energy Choice Ohio notes recent switchers should still return an opt-out notice if they do not want to be moved.
How to switch suppliers step by step
PUCO’s electric switching checklist is short:
- Compare offers using your Price to Compare and the Apples to Apples chart.
- Contact suppliers you like, ask the recommended questions, and enroll with the supplier; the supplier contacts your utility.
- Read the supply contract before you commit.
- Watch for the utility confirmation letter. If the information is correct, you do nothing. If it is wrong, contact the utility to stop the switch. You have seven days from the postmark date⁷ to make changes.
OCC’s timeline matches that consumer-protection window: after you sign, the marketer notifies the utility, you receive a confirmation notice, and you have a seven-day grace period to cancel⁶. Enrollment then proceeds; marketer charges may take two to three months to appear or disappear on the bill. Some marketers bill separately—ask which model you are getting and keep a copy of the contract.
If a supplier later fails, Ohio law still protects continuity of service. Energy Choice FAQs say the local distribution utility acts as provider of last resort¹⁴: if your supplier cannot meet its commitments, the utility keeps service going through its standard service offer and notifies you in writing so you can shop again if you want.
Your rights, slamming, and utility-related scams
Choosing poorly can cost real money. OCC warns that purchasing from a marketer is risky if you rush, and that some households overpay by hundreds of dollars without careful comparison. Marketers may contact you by door-to-door visits, phone, mail, in-store promotions, or social media. Under Ohio rules summarized by OCC, marketers must identify themselves as marketers (not the utility or government), show photo ID, describe rate types without misleading promises, disclose contract details including cancellation rights, and leave when asked. Telephone and door-to-door enrollments generally require independent third-party verification¹⁵.
Slamming—an unauthorized supplier switch—is a bright-line problem. OCC and Energy Choice guidance both say not to share account information or show your bill unless you intend to switch. If a company you do not recognize appears on your bill, contact the utility, ask to return to your prior arrangement, seek removal of related charges, and report the incident to PUCO. OCC’s scam fact sheet¹⁶ also covers cramming (mystery bill add-ons), fake emergency disconnect threats, utility-worker imposters, caller-ID spoofing, and solar pitches that claim to be from your utility. Utilities do not demand immediate payment by gift card, and they provide prior notice before nonpayment disconnections.
Report utility service complaints to PUCO at 1-800-686-PUCO¹⁴. OCC points consumers to the Ohio Attorney General¹⁷ and federal consumer resources for broader scam reporting, and notes marketers must follow federal Do Not Call rules.
PUCO’s own FAQ on mystery sales calls is simple: check whether the company is on the list of certified suppliers¹⁴ before you treat the pitch as legitimate.
Who can shop—and when staying put is smarter
Not every Cincinnati-area meter is eligible. Energy Choice FAQs state that co-op members, PIPP participants, and municipal power customers¹⁴ are not eligible for the choice program. Apples to Apples repeats the PIPP Plus exclusion for alternate-supplier enrollment.
Even eligible customers should treat “no” as a valid answer. PUCO says there is no deadline to choose a supplier, and skipping a switch still leaves you with reliable local distribution service. OCC advises against buying energy during a door-to-door sale or in-store promotion, and against sharing a utility bill or account number casually. If your current fixed contract still beats today’s offers after early-termination math, waiting can be the win.
Small businesses on Duke DS or DM tariffs should use the matching Apples to Apples commercial charts and confirm the tariff code on the bill before comparing. Higher-load commercial customers may need tailored supplier outreach beyond the residential snapshot charts—but the same contract hygiene still applies.
Beyond the rate: usage, efficiency, and bill control
Supplier shopping only rewrites the generation line. Your total bill still multiplies rate by kilowatt-hours, then adds regulated delivery and other charges. Energy Choice Ohio’s conservation page notes that practicing energy conservation¹⁸ can reduce usage and lower utility costs whether you rent or own—examples include thermostat setbacks, sealing drafts, and choosing efficient equipment. Looking for ENERGY STAR¹⁹ labeled products is one practical filter when you replace appliances or HVAC equipment.
OCC’s assistance materials also matter when affordability—not shopping—is the real issue: programs such as HEAP and PIPP Plus are designed for bill payment help, and PIPP enrollment itself removes you from competitive shopping eligibility while you are on the plan.
For Cincinnati residents deciding what to do this week, the decision tree stays simple. Confirm you are a Duke Energy Ohio customer eligible for choice. Pull several bills and note the Price to Compare. Open the official Apples to Apples Duke residential chart. Compare any marketer or aggregation offer against that benchmark and against the contract risks OCC flags. If the math and the terms both work, enroll through a certified supplier and use the seven-day confirmation window. If they do not, staying on the standard service offer is not failure—it is a competitive outcome.
