AES Ohio Interconnection

AES Ohio posts interconnection applications and technical requirements on its interconnection page. Applications are submitted through AES Ohio’s online interconnection system. Net metering billing rules are in AES Ohio’s PUCO-approved tariff (section D, Net Metering).

AES Ohio’s published residential levels (as of the live interconnection page we reviewed in September 2026):

• Level 1 — most residential systems 0–25 kW. Application cost listed at $50.
• Level 2 — 25 kW to 2 MW. Application cost listed at $50 + $1 per kW, plus any network upgrades.
• Level 3 — above 2 MW. Higher study and application costs; longer timeline.

AES Ohio also lists a $95 one-time fee to exchange the existing utility meter with a net meter when that upgrade is required. On its net-metering page, AES states that the average total cost for AES Ohio-related charges for a residential customer is $130 (application review plus meter exchange). Fees can change — confirm on the current AES Ohio pages when you apply.

Net Metering and Bill Credits

AES Ohio’s interconnection FAQ describes net energy metering with a special meter that measures energy taken from the grid and excess generation sent to the grid, then calculates the difference (“net”).

In AES Ohio’s net-metering materials, that two-way accounting is commonly framed as:

• Delivered — energy AES supplies to the customer
• Received — energy the customer sends back to the grid
• Net kWh — Delivered minus Received

AES states that when generation exceeds delivered energy during a billing month, the customer receives a generation credit for excess energy. AES states that this credit is based on the Standard Offer Rate unless the customer has an alternate generation supplier / net-meter contract. Not every AES customer automatically receives the same export credit — competitive retail supply contracts can change the generation line.

AES answers “Will I get a check for extra power I generate?” with No. Extra generation becomes a credit that offsets charges on the current bill, with any remaining credit applied to the next month’s bill.

AES also states that most inverter-based systems will not keep the house powered during a utility outage — a safety design so the array cannot back-feed distribution lines. Backup needs a properly configured battery and inverter. See solar batteries in Ohio.

AES Ohio’s FAQ cites Ohio Rule 4901:1-10-28 for sizing: a customer-generator must not exceed 120% of the previous year’s historical usage. That statewide rule sits under the AES tariff.

Timeline Notes (From AES Ohio)

AES Ohio publishes business-day clocks for complete applications. For Level 1, their table lists 10 days to notice receipt, 10 days to notice approval, and 5 days to provide the interconnection agreement after the relevant triggers. Incomplete applications are returned with what is missing.

Those clocks start when AES Ohio has a complete application. City permits and equipment lead times are separate. We give a realistic schedule for your address when we quote.

AES Ohio Solar — FAQs

Will AES Ohio mail a check for leftover solar?

AES Ohio’s posted FAQ says no — you receive bill credits, with unused credit applied to later bills.

Will solar keep the lights on in an outage?

Usually not with a standard grid-tied inverter. AES Ohio’s FAQ is explicit that most inverter-based systems shut down so they cannot back-feed lines.

How big can my system be?

AES Ohio points to OAC 4901:1-10-28: do not exceed 120% of the previous year’s historical usage.
