What the U.S. government data says about AEP Ohio

• Commercial customers185,8772025, EIA Form EIA-861
• Buy energy from a supplier94%of commercial kWh · 71% of customers
• Delivery price3.58¢average per kWh, delivery-only customers

In 2025, 94% of the commercial kWh delivered by AEP Ohio went to customers buying energy from a competitive supplier, and 6% stayed on the utility's default service. By customer count it is 71%, because the businesses that shop tend to be the larger ones.

AEP Ohio’s delivery charges averaged 3.58¢ per kWh across its 131,154 delivery-only commercial customers: the part of the bill no supplier can change. It is an average over customers of every size. Large customers pay far less per kWh than small ones, so your own delivery charge per kWh will differ; the average customer here used about 15,966 kWh a month.

AEP Ohio customers went without power for an average of 145 minutes in 2025, excluding major storms, with about 1.08 interruptions per customer. The average across U.S. utilities reporting the same way is 124 minutes.

EIA records AEP Ohio serving customers in 53 Ohio counties: Adams, Allen, Ashland, Athens, Auglaize, Belmont, Carroll, Columbiana, Coshocton, Crawford, Darke, Defiance, Delaware, Fairfield, and 39 more. A county can be shared between utilities, so this does not tell you who serves a given address.

What AEP Ohio controls and what it does not

Cities and areas in this territory

Territory boundaries do not follow city limits. Two addresses on the same street can sit in different territories, which is why we confirm the Account number rather than inferring eligibility from the city or the ZIP code. Inferring from location is the most common way a commercial account is told it can do something it cannot.

Which lever moves which charge

This is the question a utility page exists to answer. If you change something at the meter, which line on the bill actually moves — and which one does not move no matter what you do?

Fixed customer chargeNothing you do

A flat monthly amount for being connected. It does not move with consumption or with peak.

No lever

Volumetric distributionHow much you use

Charged per kilowatt-hour. This is the line that efficiency work moves.

Use less

Demand chargeHow hard you draw

Charged per kilowatt of billed demand. Set by your highest interval, not by your total — which is why cutting consumption may not move it at all.

Lower the peak

Riders and surchargesRegulatory filings

Adjusted periodically through approved filings. They step rather than scale, and nothing you do at the meter changes them.

No lever

Schematic shapes, not AEP Ohio's actual rates — those come from the filed tariff. The point is the behaviour: two of these four respond to something you control, and a supplier changes none of them.

What sits inside the delivery charge from AEP Ohio

Delivery is not one number. On a commercial account it is typically assembled from several components, each set by the filed tariff and each behaving differently as your usage changes:

• A fixed customer or meter charge, which does not move with consumption at all.
• A volumetric distribution charge per kWh, which scales with how much you use.
• A demand charge per kW where the account is demand-metered, which scales with how hard you draw rather than how much you use — and which is where a low load factor account gets hurt.
• Riders and surcharges, adjusted periodically through regulatory filings, covering items such as transmission cost recovery, energy efficiency programs and storm or system restoration costs.

None of these changes when you change supplier. Understanding the mix matters because it determines which action actually moves your bill: reducing consumption attacks the volumetric component, reducing peak draw attacks the demand component, and neither one touches the fixed charge.

The other territories in Ohio

Boundaries do not follow city limits. If you are not certain which of these serves your address, confirm the Account number printed on the bill rather than inferring it from the city.

What the AEP Ohio tariff says: Schedules GS-NDM (General Service - Non-Demand Metered) and GS (General Service)

Read 2026-10-31 from Ohio Power Company (AEP Ohio) Electric Tariff, P.U.C.O. No. 22, Schedules GS-NDM and GS (Original Sheet Nos. 220-1 to 220-5), effective April 10, 2026. Each figure is quoted from that document, and it is a schedule figure, not a bill estimate. See every tariff quoted on this site. The tariff and the schedule code on your bill control what applies to you.

Who GS-NDM and GS cover

Schedule GS-NDM (General Service - Non-Demand Metered) is for general service to secondary customers with maximum demands less than 10 kW. Schedule GS (General Service) is for non-residential customers at secondary, primary or transmission voltage who request and receive generation service from the standard service offer (SSO) or a qualified competitive retail electric service (CRES) provider.

GS-NDM charges

The GS-NDM monthly rate table shows, in its Distribution column, a Customer Charge of $21.00 and an Energy Charge of 2.71520 cents per kWh. The minimum monthly charge under GS-NDM is the sum of the customer charge and all applicable riders.

GS charges by service voltage

The GS monthly rate table shows, for Secondary service, a Demand Charge of $9.05 per kW, an Excess Reactive Demand charge of $1.67 per kVA and a Customer Charge of $21.00. For Primary service it shows $8.08 per kW, $1.62 per kVA and a Customer Charge of $186.30.

How GS billing demand is set

Billing demand is the single highest 30-minute integrated peak in kW registered during the month. For accounts over 100 kW it is the greater of four things: that peak; contract capacity less 100 kW multiplied by 60%; HPD less 100 kW multiplied by 60% (the tariff prints these two without parentheses); and any minimum billing demand in the service contract. HPD is the highest previously established monthly billing demand during the past 11 months.

GS excess kVA demand

The monthly KVA demand is the maximum metered KW demand divided by the average monthly power factor. The excess KVA demand, if any, is the amount by which the monthly KVA demand exceeds the greater of 115% of the maximum metered KW demand or 100 KVA.

GS minimum monthly charge

The minimum monthly charge under Schedule GS is the sum of the customer charge, the product of the demand charge and the monthly billing demand, and all Commission-approved riders shown on Sheet Number 104-1.

Billed separately

Both schedules say monthly charges are adjusted by the Commission-approved riders on Sheet Number 104-1. Schedule GS applies to customers who receive generation service from the SSO or a qualified CRES provider. The rate tables print no rider amount and no generation charge, so none of those is in the figures above.

What to pull off an AEP Ohio bill before any conversation

• Account number — the identifier that determines territory and eligibility
• Rate schedule code as printed on the bill
• 12 months of kWh, and peak kW if the account is demand-metered
• The delivery and supply sections, kept separate
• Current supplier and contract expiry, if any
