Average Electric Bill in Ohio

What the average Ohio electric bill actually is

The average residential electricity bill in Ohio is $165.14 a month, made up of roughly 846 kWh at 19.52 cents per kWh as of May 2026. The national figures are 863 kWh at 18.44 cents for $159.14. Ohio is within a few percent of the country on all three measures at once, which makes it one of the least distinctive states in the raw statistics and one of the most complicated once you look at what produces the number.

The reason is that Ohio's average is assembled from parts that vary far more than the total suggests. Four separate distribution utilities operate here, each with its own delivery rates and its own stack of riders — the itemised charges on the delivery side that recover specific approved costs. On top of that, the supply portion might be the utility's default price, a competitive supplier contract, or a rate a city negotiated for its residents through governmental aggregation. Two neighbours in identical houses can pay different prices for both halves of the bill.

The average also flattens a two-peaked calendar. Ohio has hot humid summers and cold winters, and while heating runs mostly on natural gas, the cooling season produces a clear July and August peak while winter brings a smaller secondary rise from furnace blowers, lighting and indoor hours.

Do not benchmark your household against the state figure. Take the kilowatt-hours from your own statement, run them through the electricity bill calculator, then compare the same month against the same month a year earlier.

Why Ohio electricity costs 19.52 cents per kilowatt-hour

Ohio sits inside PJM, the regional wholesale market covering much of the mid-Atlantic and eastern Midwest, and it is structurally unbundled: the utilities were separated from their generation, so the companies delivering your power are wires businesses that do not own the plants serving you. Default supply is bought through competitive procurement rather than produced in-house, so the generation portion of an Ohio bill tracks market outcomes rather than the book cost of a utility fleet.

That market runs largely on natural gas at the margin, with a substantial nuclear and coal base and growing renewable capacity. Ohio's own resource position is reasonable — gas production, coal history, access to cheap regional supply — which is why generation has not historically been the state's problem.

The pressure has been on the other side. Delivery costs in Ohio are recovered through an unusually elaborate structure of riders, each authorised to recover a defined category of cost: distribution investment, storm restoration, efficiency programmes, universal service, and various transition and true-up mechanisms. Individually each is modest. Collectively they are a significant fraction of the bill, they change on their own schedules, and no competitive supplier can touch any of them. A household that switches supply and sees the bill rise anyway has usually met a rider adjustment.

Regional capacity costs — what the market charges to guarantee generation is available on the worst day of the year — have also risen across PJM and flow through to customers. That is a market-wide phenomenon rather than an Ohio one. Our guide to supply versus delivery charges shows how to separate the two halves on your statement.

Why Ohio households use close to the national average

At 846 kWh a month Ohio sits marginally below the national average, and that unremarkable number is the product of two strong forces cancelling each other.

Pulling consumption down: natural gas. Ohio has among the deeper natural gas penetrations in the country, with mains reaching most of the urban and suburban housing stock and doing the space heating, water heating and much of the cooking and drying. Space heating is the largest energy load in a cold-climate house, and in Ohio it mostly does not appear on the electric bill — which keeps consumption far below what the state's winters would otherwise imply. Ohio also has a substantial stock of older, smaller housing in its industrial cities.

Pushing consumption up: the summer. Ohio gets genuine heat and genuine humidity from June through early September, and humidity is the expensive half — much of an air conditioner's work in July is condensing moisture out of the air rather than lowering temperature, and none of that work shows on a thermostat. Central air conditioning is standard in newer construction and increasingly retrofitted into older homes. Suburban housing built since the 1990s is considerably larger than the state's older stock, and conditioned square footage is the most reliable predictor of consumption there is.

The winter contribution is smaller but real: furnace blower motors run for long stretches in cold snaps, lighting hours are long, and basements hold dehumidifiers and freezers. The households that diverge sharply are those without gas service — rural properties and manufactured homes on electric resistance heat, which converts electricity to heat one-for-one.

What you can control: shopping for supply in Ohio

Ohio is a retail choice state, and it is a heavily marketed one. Households can buy the generation portion of their service from a competitive supplier instead of the utility's default, which in Ohio is the standard service offer procured by competitive auction. The utility still owns the wires, still restores your outage and still bills you. Only supply is in play, and delivery — with its full stack of riders — is untouchable.

The Public Utilities Commission of Ohio publishes a comparison of certified supplier offers, and that is the right starting point rather than whoever knocked on the door. Then apply arithmetic:

• Teaser rates quoted at benchmark usage. Offers are commonly illustrated at 750 or 1,000 kWh a month. Ohio's average is 846, and yours may be well below that in April. Any fixed monthly charge produces a higher effective per-kWh price than the headline implies.
• Minimum usage fees. Some plans charge a penalty if you fall below a usage threshold, which turns a mild shoulder month into an expensive one and punishes exactly the behaviour you want to reward.
• Bill-credit plans. A credit awarded only above a usage threshold rewards you for consuming more. A household that lands just below the threshold in a mild month pays a high underlying rate with nothing to offset it.
• Contracts that roll to variable. An introductory fixed price expiring into a rate the supplier sets at its own discretion is the most reliable way to end up paying more than the standard service offer. Diarise every expiry date on the day you sign.
• Early termination fees. These remove your ability to leave when the price turns against you, which is precisely when leaving has value.

Run the numbers before signing. At 846 kWh, beating the default by two cents per kWh saves about $17 a month, roughly $203 a year — worth having, and small enough that one monthly fee or two months on a post-teaser variable rate wipes it out.

The four delivery companies, and why the boundary matters

Ohio has four investor-owned electric distribution utilities, and which one serves your address is decided entirely by geography. You cannot change it, and it affects the delivery half of your bill permanently.

AEP Ohio covers central and southeastern Ohio, including Columbus, as part of a large multi-state system. Its territory mixes a fast-growing metropolitan area with sparsely populated Appalachian country, two very different things to serve from one rate base.

FirstEnergy's Ohio utilities are the structural oddity: Ohio Edison, the Cleveland Electric Illuminating Company and Toledo Edison operate under one parent as three legally distinct companies with their own rate schedules and rider stacks. Cleveland Electric Illuminating serves a dense urban core, Ohio Edison a broad swathe of northeastern and central Ohio, Toledo Edison the northwest. Households a short distance apart can be customers of different companies with different delivery prices.

Duke Energy Ohio serves the Cincinnati area and is a combined electric and gas utility, so many customers receive both commodities from the same company.

AES Ohio, the former Dayton Power and Light, serves the Dayton region — a compact territory and the smallest of the four.

Alongside them, Ohio has a substantial municipal electric sector, including systems in Cleveland and dozens of smaller cities, plus rural cooperatives across much of the countryside. Both are community-owned: municipal rates are set by the city, cooperative rates by a member-elected board, and their customers are generally outside the retail choice market.

Governmental aggregation: the supply choice most Ohioans never made

Ohio has one feature that shapes more household bills than individual shopping does, and many residents do not know they are in it. Under governmental aggregation, a city, village, township or county can negotiate an electricity supply price on behalf of the residents in its boundaries and enrol them automatically, with the right to opt out. Where a community has done this, the default outcome for a household that does nothing is not the utility's standard service offer — it is the aggregation contract.

The logic is sound. A municipality bargaining for tens of thousands of accounts has leverage a single household does not, and the contract is negotiated by people with no commission to earn from you. In practice, aggregations have often delivered prices below the standard service offer, and they spare residents the entire apparatus of doorstep sales and teaser pricing.

There are things to understand about it. You are enrolled by default rather than by choice, and the notice explaining this arrives by mail among everything else that arrives by mail. Aggregation contracts have terms and expiry dates like any other supply contract, and what happens at expiry matters. Being in one does not lock you in — you retain the right to opt out and take standard service or an individual supplier — but leaving may carry conditions worth reading first. And an aggregation price that beat the default when negotiated will not necessarily beat it two years later, because market conditions move and the contract does not.

The practical instruction is simple: find out what supplies your generation before evaluating any offer. Look at the supply section of your bill and identify the name printed there. If it is your city's aggregation programme, a supplier pitching you is asking you to leave a negotiated group contract for an individual one, and that deserves the same arithmetic as any other comparison.
