Why Is My Electric Bill So High in Ohio?

What should you check first when your electric bill jumps?

Start with what your utility must print. Ohio's bill rules, 4901:1-10-22 for a bill with utility charges only and 4901:1-10-33 for one that also carries a supplier's charges, require every residential bill to show the service period dates, the meter readings, the kWh used and whether the bill is estimated. A bill must also show your kWh for each of the last twelve months, with a total and an average.

1. Count the days in the service period. A 33-day period holds 17.9% more days than a 28-day one, so the same daily use adds up to more kWh.
2. Look for the estimated flag. An estimated bill is built from past use, and a later actual reading can adjust it.
3. Compare this bill's kWh with the same month a year ago in the twelve-month history.
4. Find the supplier line. If a supplier is named, its price, not the default rate, sets your supply charge.
5. Divide the total by the kWh used and compare that all-in price with last month's.

Here is the billing-days effect as an example, not a prediction. A home that uses 30 kWh a day uses 840 kWh over 28 days and 990 kWh over 33 days. At the 2024 statewide average price of 15.99 cents per kWh, as reported by the U.S. Energy Information Administration, that gap is $23.99, with no change in habits.

How do usage, weather and heating raise an electric bill?

Usage is the first suspect, because a bill is kWh times price plus fixed charges. Heating, cooling, water heating and laundry all draw kWh. AES Ohio's bill guide points to a section that compares your average daily kWh and the temperature with last year and last month.

Some prices move with the season too. FirstEnergy says its Ohio prices update each June 1 and are seasonal, with summer pricing for June through August and winter pricing for the other months. Ohio Edison's chart on PUCO's site carries a note for qualifying electric heating customers: from September 1 to May 31 their price to compare, the per-kWh supply benchmark on the bill, can differ, and the bill's message section prints it. PUCO's chart lists Ohio Edison's price to compare for shorter periods, so it can also change between June resets.

For AES Ohio, PUCO's chart describes a yearly weighted average, and heavier winter use pulls that figure down. Always read the figure on your own bill.

Why is my electric bill so high in Ohio compared with last year?

If your kWh match last year, a higher bill points to a price change somewhere on the bill. Each utility's default rate resets when a new period starts, and PUCO's chart shows the rate for that period. The statewide trend is on our average electric bill in Ohio page.

All six utilities have a published rate for today, so each row compares the current period with the one before it.

Multiply any change in the rate by your kWh to see its effect, or run your own numbers in the electric bill calculator. The table shows a one-cent change at four example levels of use, expressed in dollars for a single month.

AES Ohio's supply page says PJM's capacity auction results were significantly higher for the 2026/2027 delivery year. PJM is the grid operator that covers Ohio, and capacity is the cost of having enough power ready. The Ohio rate increases tracker lists dated PUCO decisions, and each history page above shows one utility's periods. The Ohio standard service offer guide explains how auctions set the default rate.

How do you match what you see on the bill to a cause?

Use the pattern on your bill to narrow the cause. The table pairs each pattern with the likeliest cause and the part of the bill to read. These are starting points, since more than one cause can apply at once.

If a supplier appears that you did not choose, your community may run an opt-out program under section 4928.20. See Ohio electric aggregation for how those programs work. A bill that fits no row deserves a call to your utility. Ask for the readings and the rate in force for each day of the service period, and write down the answer.

Which charges on your bill are delivery and riders?

Delivery is the share of the bill for moving power to you: the high-voltage grid and the local wires. Your utility bills it whichever supplier you use, and AEP Ohio's choice page says it still supplies transmission and distribution after a switch.

Delivery rates are set in cases before PUCO, apart from the supply auctions. AES Ohio says its auction is separate from its transmission and distribution cases that need PUCO approval. The default rate and the price to compare cover supply only, so a change in delivery charges will not appear in them.

Look for any rider, a smaller charge or credit added to the bill by a PUCO order. A rider can start or change in a month when your use did not.

Can a supplier's rate make an electric bill jump?

Yes, when you have a supplier. Its price replaces the default rate for the supply portion. The glossary on PUCO's Energy Choice Ohio site defines a variable price as a price that can change "by the hour, day, month, etc., according to the terms and conditions in the supplier's disclosure statement." A fixed price, it says, stays the same for a fixed amount of time.

Check the supplier's name and rate on your bill, then read the contract. PUCO's questions to ask suppliers include whether the price is fixed, how it changes if it does, and what happens when the contract expires. Ask before a term ends, because the price after it may differ from the price during it. Our guide to variable rate electric in Ohio explains the two types.

You can return to your utility's default rate. PUCO says to contact your supplier or your utility, and to check your contract for an early termination fee first. AES Ohio's supply page says a supplier's name appears under Supply Charges on its bill.

Could an estimated reading or a billing error be behind it?

It can be. AES Ohio's bill guide says that in months it does not read your meter, it calculates the bill from past use and may adjust it after an actual reading. Ohio's bill rules require an estimated bill to be identified.

The utility bill rule also requires each electric utility to publish an online bill calculator that shows every rate and charge. You enter your billing numbers and check that the bill is accurate. For a bill with no supplier charges, the rule also says to call or write your utility first.

If the utility does not resolve it, call the PUCO Call Center at (800) 686-7826. PUCO's contact page lists utility complaints and supplier complaints among the issues it handles.

The notice that the rule requires on your bill gives weekday hours of eight a.m. to five p.m. It also lists the 7-1-1 relay service for hearing or speech impaired callers. The Office of the Ohio Consumers' Counsel (OCC) represents utility customers in PUCO matters, and the rule prints its number too.

What can lower an electric bill in Ohio, and what cannot?

Your use is the part you control. Fewer kWh means a smaller supply and delivery charge, and the twelve-month history on your bill shows where your use runs highest. Delivery rates are set by PUCO orders and are the same whichever supplier you pick.

Only the supply portion can change by shopping. Shopping makes sense only when an offer's price per kWh, with its fees added, comes in under your price to compare, and that benchmark can move during a contract. Fees, an exit charge or a rate that floats after the first months can wipe out a small difference, so a lower headline price is not a promise of a lower bill.

Where can you get help if you cannot pay a high bill?

Call your utility first. The utility bill rule requires each utility to have a policy for handling billing disputes and requests for payment arrangements, and PUCO says electric distribution companies offer payment plans. Our help with electric bills page covers assistance programs such as the Home Energy Assistance Program (HEAP) and the Percentage of Income Payment Plan (PIPP Plus).
