Why is my electric bill so high in Ohio?

Almost every high bill traces to one or more of seven causes. Only some of them are yours to fix, so the table shows what each looks like on your bill and who controls it. Unsure which one applies? The next section's tool sorts it out.

Set the high bill next to a lower one from before, and the tool splits the jump into dollars. The best match is the same month a year ago, since the weather then was close to now. Last month's bill works too.

1. 1
   Choose your bills.

   Set the high bill next to an older one.

2. 2
   Copy the kWh.

   Each bill shows the kWh you used.

3. 3
   Copy the two charges.

   Find the generation or supply charge and the distribution or delivery charge. No split on your bill? Skip those boxes.

4. 4
   Add the total.

   Use only that bill's new charges, and leave out any balance carried over.

5. 5
   Tap Find the cause.

   The tool shows the dollars added by extra power, a higher supply price and a higher delivery rate.

The result shows how many dollars each cause added, so you know which one to fix first. Treat it as a guide built from what you type, not a bill. It cannot see credits, late fees, taxes or the fine print in a supplier's contract.

If the kWh on the new bill is higher, yes, and that explains at least part of the jump. Open both bills and read the kWh first.

In 2025, says the EIA, the average Ohio home used about 874 kWh a month and was billed about $148. A home that heats with electricity uses much more in winter. Also check the days on the bill. A 35-day bill has 17% more days than a 30-day bill, so it can use 17% more power with no change at home.

Most jumps in use come from the same places:

• Heating. Electric heat or plug-in heaters during a freeze.
• Cooling. Air conditioning that runs more hours when it is hot.
• Hot water. An electric water heater, or one with a worn element.
• New gear. A car charger, a spa or a basement dehumidifier.

To price a device, take its watts, divide by 1,000, multiply by the hours you run it a day, then by 30. The result is kWh for a month.

These are examples, not measurements. The cost column uses 19 cents per kWh, close to the Ohio average of 19.45¢ in July 2026. Your devices, hours and price will differ. To find what one kWh costs you, all in, use our cost per kWh tool.

At every big Ohio utility it did in June 2025, and it can move again on a set day. Supply is the price of the electricity itself. If you chose no supplier, your utility sets it at auctions and calls it the price to compare. That is why it can jump all at once.

In June 2025 the AEP Ohio supply price jumped 36%, says the Ohio Consumers' Counsel. AEP's own fact sheet says generation costs rose about $27 a month that summer. Prices moved again in 2026. At AES Ohio, the new price of 10.9¢ added $14.06 a month at 1,000 kWh, or 7.5%, says AES.

Duke Energy Ohio posts a new price each month, so a Duke bill can move even when nothing else changed. Check the supply price per kWh on your bill against the price for that month. Our Ohio rates guide lists all six, with the day each one resets.

Want a different price? The plan finder on this page lists offers for many Ohio ZIP codes, and the state's free chart lists them all. Test an offer first with the offer checker.

It may have, if a new charge or a higher delivery line shows up. The delivery charge pays for poles, wires and crews, and PUCO sets it in a rate case. A utility also adds riders, which are small extra charges for special costs. Look in the bill messages for a new charge. It often lists a case number.

A rate case changes the delivery half only. It does not touch the price to compare. If you pay a high delivery bill, you cannot shop it away. You can only cut your use or speak up in the case.

Only if your bill names a supplier. That happens when you chose one, or when a city program picked one for you, as in Cincinnati or the Toledo area. A supplier can raise your cost in two ways.

Compare two numbers on your bill: what your supplier charges per kWh, and your utility's price to compare. If yours is higher, you are paying more than the default.

As of October 24, 2026, 52% of the per-kWh offers on the state's chart cost less than the price to compare. That count comes from the state's chart, not from our partner's finder. Low is not always cheaper, though. A short deal can end in a variable rate.

Ohio's rules say a supplier must warn you before a fixed deal ends. Our contract ending guide shows the notices and the dates. You can go back to your utility's price, but your contract may carry an early termination fee, so read it first. Not sure the seller on your bill is even certified? Our supplier check tells you in two minutes.

A guessed meter read, a budget plan catch-up or a new meter can each make one bill jump while your rates stay the same.

If you cannot pay, the OCC lists help on its pages for the Home Energy Assistance Program and the Percentage of Income Payment Plan. Call your utility before a bill goes past due.

If your bill changed look on Oct. 1

On Oct. 1, 2026, AEP Ohio became Ohio Power Company. It also moved to a new bill design and a new website. Rates did not change with the name, says Local12. If your bill looks different, check the total and the kWh. The layout may have moved the charges.

Find the cause first, then fix the part you control. Most homes need only the first two or three moves.

1. Find your causeUse the tool above. It sorts the jump into power used, supply price and delivery rate.
2. Call your utilityAsk for a meter re-read if the kWh looks wrong, and ask about a payment plan or budget billing.
3. Check your supplierIf a supplier's name is on the bill, compare its price with the price to compare.
4. Shop if it makes senseTest an offer with the offer checker. Add the monthly fee and look at the term.
5. File a complaintIf the utility will not fix a mistake, call PUCO at 1-800-686-7826.
