Best Electricity Rates in Cincinnati 2026: Duke Energy Price to Compare & Suppliers

If you live in Cincinnati, your June 2026 electric bill just got more expensive — and most households never noticed why. On June 1, 2026, Duke Energy Ohio’s residential Price to Compare climbed to 10.70¢ per kWh, up from 10.08¢, a jump of a little over 6% on the supply portion of your bill. For a typical home using 1,000 kWh a month, that’s roughly $6 more every month for doing nothing. The good news: Ohio is a deregulated electricity market, which means the supply rate you pay is a choice, not a fixed cost. This guide walks through what the Price to Compare means, how Cincinnati’s electric aggregation program stacks up, and how to lock in a rate that beats Duke’s default.

How Electricity Choice Works in Cincinnati

Ohio deregulated its retail electricity market in 2001, separating the company that delivers power from the company that generates and supplies it. In Cincinnati and the surrounding Hamilton County suburbs, Duke Energy Ohio still owns the poles and wires, reads your meter, restores power after storms, and sends your bill. That part never changes no matter who you buy from. What you can change is the generation supply — the actual electrons — by signing up with a competitive retail electric supplier (CRES) certified by the Public Utilities Commission of Ohio (PUCO).

When you shop, your supply charge is replaced by the competitive supplier’s rate, but delivery charges, the customer service charge, and riders stay on the same Duke bill. You get one bill, power flows exactly as before, and if your competitive supplier ever fails, Duke is legally required to keep you connected on the default service. There is no risk of the lights going out by switching.

Duke Energy Ohio Price to Compare — June 2026

The Price to Compare (PTC) is the single most important number for any Cincinnati shopper. It’s the all-in supply rate — generation plus transmission — that you pay if you do nothing and stay on Duke’s Standard Service Offer. As of June 1, 2026, the residential non-PIPP Price to Compare is 10.7016¢ per kWh. Any competitive offer below that number saves you money on supply; any offer above it costs you more.

It’s worth understanding why the PTC moves. Duke procures default generation supply through periodic competitive auctions, and those wholesale results flow through to the PTC. The June 2026 increase reflects higher capacity and energy costs across the PJM grid that serves Ohio. Because the PTC resets on a schedule, a fixed-rate competitive plan can shield you from the next increase — something the default service can never do.

The Cincinnati Electric Aggregation Program

Cincinnati runs one of the largest municipal electric aggregation programs in the country. Under governmental aggregation, the city negotiates a bulk supply rate on behalf of all eligible residents, who are automatically enrolled unless they opt out. For the term running May 2026 through November 2026, the city secured an introductory fixed rate of 10.44¢ per kWh for 100% green power — below the current Duke Price to Compare and backed by renewable energy certificates.

For many households, the aggregation rate is the path of least resistance: it’s competitive, it’s green, and it requires no action. But aggregation isn’t always the cheapest option, and the rate changes each contract term. If you’re a high-usage household or you want to lock a longer term to ride out future PTC increases, shopping the open market yourself can beat the aggregation rate — which is exactly why comparing matters.

How to Find the Best Cincinnati Electricity Rate

Start by pulling out a recent Duke Energy bill and finding your average monthly kWh usage — it’s printed right on the statement, usually as a 12-month graph. That number, multiplied by any rate you’re quoted, tells you the real monthly cost. Then follow three rules:

Compare against the Price to Compare, not against your old rate. The 10.70¢ PTC is your benchmark. A 9.5¢ fixed plan saves you over a penny per kWh on supply, which adds up to real money over a year.

Favor fixed over variable. A 12- to 24-month fixed rate locks your supply price for the entire term. Variable and “intro” rates can reset sharply higher after a few months — the single most common complaint in deregulated markets nationwide.

Read the contract terms. Check for monthly fees, early termination fees, and what happens at the end of the term. Many plans roll to a much higher month-to-month rate when the fixed period ends, so set a calendar reminder to re-shop.

Fixed vs. Aggregation vs. Default: Which Is Right for You?

If you want zero effort and a green rate, the city aggregation at 10.44¢ is a reasonable default and beats Duke’s PTC today. If you want maximum rate certainty, a fixed-rate competitive plan locked for 18 to 36 months protects you from the next several PTC resets — valuable given the upward trend in PJM capacity costs. The one option that rarely makes sense is doing nothing and sitting on the standard Duke Price to Compare, because it carries a small risk premium and reprices on Duke’s schedule rather than yours.

Frequently Asked Questions

What is the Duke Energy Ohio Price to Compare in June 2026?
The residential non-PIPP Price to Compare is 10.7016¢ per kWh, effective June 1, 2026 — up about 6% from the prior 10.08¢.

Is switching electricity suppliers in Cincinnati safe?
Yes. Duke Energy still delivers your power and restores outages regardless of who supplies your generation. If a competitive supplier fails, you’re automatically returned to Duke’s default service with no interruption.

What is the Cincinnati electric aggregation rate?
For the May–November 2026 term, the city’s governmental aggregation rate is 10.44¢ per kWh for 100% green power, which is below the current Duke Price to Compare.

Will I get a separate bill if I switch suppliers?
No. You continue to receive one consolidated bill from Duke Energy. The supplier’s charge simply replaces Duke’s default generation charge.

Should I choose a fixed or variable rate?
For most households, fixed. A fixed rate locks your supply price for the full term and protects you from the periodic Price to Compare increases that hit default and variable customers.

How do I switch back to Duke if I change my mind?
You can return to Duke’s standard service at any time, though a competitive contract may carry an early termination fee. Always check that fee before signing.

What Cincinnati Households Actually Pay

To put the numbers in context, a Cincinnati home using 1,000 kWh a month pays roughly $107 in supply alone at the June 2026 Price to Compare of 10.70¢ — before a dollar of delivery is added. Stack delivery charges, the customer charge, and riders on top, and a typical all-in Duke Energy Ohio residential bill lands well above that. The supply portion is the only piece a competitive plan or the city aggregation can move, so frame your savings against the supply line, not the total. Even a one-cent reduction on supply — say a 9.7¢ fixed plan against the 10.70¢ default — saves about $120 a year for that 1,000 kWh household.

One note for lower-income customers: Duke Energy Ohio’s PIPP (Percentage of Income Payment Plan) Plus program offers a different rate structure for qualifying households, and PIPP participants should review how shopping interacts with the program before switching, since enrolling with a competitive supplier can affect PIPP benefits. For everyone else, the shopping math is simple: beat 10.70¢ on a fixed term and you win.

Rates cited are current as of June 2026 and change on Duke Energy’s and the city of Cincinnati’s procurement schedules. Always confirm the live Price to Compare on your most recent bill before signing a competitive supply contract.
