AEP Ohio Solar for Homeowners

How Solar Works With AEP Ohio

If your electric bill says AEP Ohio, rooftop solar does not replace the utility. The array produces power for your home first. When production is higher than what you are using, extra energy can go back to AEP Ohio’s system. When production is lower — nights, cloudy days, winter — you still take power from the grid.

That two-way connection is called interconnection. AEP Ohio must review and approve any generating equipment or energy storage that will operate in parallel with its system. State rules for that review are in Ohio Administrative Code Chapter 4901:1-22. AEP Ohio also publishes its own interconnection process, application tips, and technical requirements.

Parts of Columbus are served by the municipal Columbus Division of Power instead of AEP Ohio. Confirm the utility name on your bill. If it is Division of Power, start with our Columbus solar page.

Distribution, Generation, Interconnection, and Net Metering Are Different

AEP Ohio as the distribution utility. In AEP Ohio territory, AEP Ohio owns the wires, meters, and interconnection process. That stays true whether you take AEP Ohio’s standard generation or shop with another supplier.

Standard Service Offer generation. If you have not chosen a Competitive Retail Electric Service (CRES) supplier, generation comes through AEP Ohio’s Standard Service Offer. For those accounts, Net Energy Metering Service credits extra energy using the generation energy component of the standard service schedule — not distribution, transmission, or every other line on the bill.

CRES suppliers. Ohio lets you shop for generation. If you have a CRES supplier, AEP Ohio still delivers the power. Excess-generation credits are then arranged with that supplier. A CRES provider may offer its own credit method, or none; it is not required to offer net metering. Tell us if you are on standard service or a shopping contract when you send your bill.

Interconnection is AEP Ohio’s review to connect generating equipment or energy storage in parallel with its system. That runs through PowerClerk, technical documents, and a lockable AC disconnect. Approval of an interconnection application is not the same as permission to turn the system on.

Permission to operate comes after install, field verification, and a meter that can register energy in both directions. AEP Ohio’s application materials say the generator must not be placed in service until that notice is issued.

AEP Ohio Interconnection and Permission to Operate

Homeowners and installers apply through AEP Ohio’s online PowerClerk portal after creating an account. AEP Ohio’s generating-equipment page is the official starting point: aepohio.com generating equipment.

A complete residential application typically includes customer name and service address that match the AEP Ohio account, equipment spec sheets, a site diagram, an electrical one-line diagram, UL 1741 / IEEE 1547 inverter documentation, and proof of insurance. Meter collar devices are not approved in AEP Ohio territory.

AEP Ohio also requires a readily accessible, lockable, visible-break AC disconnect between the home’s generating equipment and the utility system. The company standard is a single isolation device, generally next to the meter, clearly labeled so crews can isolate the solar equipment.

AEP Ohio’s Quick Start guide for homeowners says that if the proposed equipment meets technical and safety requirements, an interconnection service agreement is typically issued within 35 days of a fully completed application, and that most applications are approved in the first review. Some projects take longer, especially if the application is incomplete or extra study is needed.

After install, AEP Ohio does a post-installation field verification to confirm the system matches the application. The generator must not be placed in service until AEP Ohio issues Permission to Operate. After a passing verification, AEP Ohio installs a meter that can register energy in both directions and notifies you when the AC disconnect can be closed.

Current AEP Ohio application materials (dated July 23, 2026) list a $50 application fee for inverter-based systems with export capacity of 25 kW or less. A dual-register meter for Net Energy Metering is installed at actual cost, typically $319 for residential customers when the customer bears the cost. In some cases AEP Ohio changes the meter at no charge. Fees and typical costs can change — AEP Ohio invoices the responsible party after the application is submitted. Do not send a payment without the invoice number.

AEP Ohio Net Energy Metering

For exports, credits, SSO vs CRES, and a worked billing example, see AEP Ohio net metering.

Interconnection approval is required before Net Energy Metering Service (NEMS) can start. NEMS is the PUCO-approved tariff that describes how excess solar is credited on an AEP Ohio bill. AEP Ohio does not buy your solar output as a separate power-purchase check.

When a billing period ends with net excess energy (more kWh sent to AEP Ohio than taken from AEP Ohio), AEP Ohio calculates a monetary credit and applies it to the current bill. Unused credit carries forward as dollars on future bills. AEP Ohio is not required to mail a check for leftover credit, and unused credit can be lost if you stop taking electric service at that premises.

That credit is based on the generation energy component of the standard service schedule for the account. It does not include distribution, transmission, or other non-generation charges. In plain English: solar can reduce the energy you buy from AEP Ohio, but it does not automatically wipe out every line on the bill.

To stay on NEMS, the system is intended primarily to offset your own use. AEP Ohio’s NEMS materials say generating facilities should not exceed 120% of the customer’s electricity requirements at interconnection, measured over a rolling 12-month period. Oversizing relative to your demand can disqualify NEMS and can add interconnection cost.

If you shop for generation with a Competitive Retail Electric Service (CRES) provider, AEP Ohio’s NEMS application notes that you arrange net-metering credits with that supplier. A CRES provider may offer a net-metering contract at its own price or credit method, and is not required to offer one. Tell us if you are on AEP Ohio’s standard service or a shopping contract when you send your bill.

What Changes on an AEP Ohio Bill

An AEP Ohio residential bill has more than one charge. Generation is the energy commodity. Distribution and transmission are the wires that deliver it. Riders and other line items can apply even when solar is producing.

Solar usually cuts the kWh you buy during sunny hours. Excess kWh in a billing period become a generation-energy credit, not a full retail “spin-the-meter-backward” credit that covers every utility charge. Fixed or minimum charges can still appear. Current AEP Ohio rates are posted at AEP Ohio rates.

That is why we start with your actual bill instead of a generic savings percentage. Usage, rate schedule, whether you shop with a CRES provider, roof, and which solar option you use (cash, loan, PPA, or Propel prepaid third-party ownership) all change the picture.

Sizing, Batteries, and AEP Ohio

We size from your usage, roof, and AEP Ohio NEMS rules — not from a one-size array. The 120% rolling-year cap is one reason a “cover the whole bill” pitch can be the wrong size.

A battery that operates in parallel with AEP Ohio still needs interconnection review. Energy storage does not automatically keep the lights on in a utility outage: AEP Ohio’s homeowner guide notes that most inverter-based systems shut down during a grid outage so they cannot back-feed distribution lines. Backup during an outage requires equipment designed for that purpose and a passing interconnection review.

Statewide residential solar context lives on Ohio solar panels. Columbus-specific AEP vs Division of Power notes are on solar in Columbus, Ohio.

AEP Ohio Solar — FAQs

Does AEP Ohio pay me for extra solar?

Not with a check for leftover kilowatt-hours. Under Schedule NEMS, extra energy in a billing period becomes a monetary credit based on the generation energy component of your service schedule. Remaining credit carries to later bills and can be lost if you stop taking AEP Ohio service at that home.

How long does AEP Ohio interconnection take?

AEP Ohio’s homeowner Quick Start guide says most homeowners finish the interconnection-service request in less than 35 days when the application is complete, and that most applications are approved in the first review. Incomplete paperwork, extra study, local permits, or a failed field check can add time. Permission to operate comes after install and field verification, not on the day panels go up.

What does interconnection cost?

AEP Ohio’s July 23, 2026 application information lists a $50 fee for inverter-based export of 25 kW or less, and a typical $319 residential dual-register meter charge when the customer pays actual meter cost. Construction on AEP Ohio’s system, if needed, is billed at actual cost. These figures can change; AEP Ohio invoices after the application is filed.

I shop for my generation. Does net metering still apply?

You still need AEP Ohio interconnection. Net-metering credits for shopping customers are arranged with the CRES provider. A supplier may offer its own credit method, or none. Send the bill so we can see whether you are on standard service or a shopping contract.

Will solar work if the power goes out?

Usually not, unless the system is designed and approved for backup. Standard grid-tied inverters shut down during an outage. A battery or backup-capable design has to be part of the interconnection application.

Where do I apply?

AEP Ohio’s official generating-equipment page explains PowerClerk registration, documents, and contacts for the Distributed Generation Coordinator (614-883-6775, dgcoordinator-ohio@aep.com). Solar Brokers can walk you through what the application is asking before you file.
