Of the 6 Ohio utilities we track, AES Ohio's Standard Service Offer is the 2nd-lowest — the range runs from 10.69¢ (Duke Energy Ohio) to 11.16¢ (The Illuminating Company (FirstEnergy)). Compare all Ohio rates →

What it means: a AES Ohio customer on a 17¢/kWh third-party supplier rate pays about $630 more per year than the Standard Service Offer (10.86¢), based on ~860 kWh/month. The audit below checks your actual rate.

The worth-it line: for a switch to save at least $10/month at ~750 kWh, a supplier offer must be a fixed rate below 9.53¢/kWh — with no monthly fee and no cancellation fee. Offers between 9.53¢ and 10.86¢ technically "beat" the Standard Service Offer but save too little to justify contract risk. The full math, all utilities →

Comparing suppliers against AES Ohio's Standard Service Offer?

Ohio's official comparison tool is Apples to Apples, run by PUCO. Ohio's official comparison tool shows every licensed supplier's rate next to the default SSO — our guide explains how to read it and when switching actually saves money.

Is AES Ohio a monopoly? Can you switch?

For delivery, yes — it's a monopoly. AES Ohio is the only company that runs the poles and wires to homes in its territory, so you can't pick a different company to deliver your power. That part is a regulated monopoly: AES Ohio, owned by AES Corporation, can only charge what the PUCO approves in a rate case.

The electricity itself, though, is open to competition. You can buy your supply from a third-party supplier, or do nothing and stay on AES Ohio's default rate — the Standard Service Offer the PUCO oversees. Switching suppliers doesn't change who delivers your power or who you call during an outage; it only changes the supply line on your bill. And if a supplier is charging more than the Standard Service Offer, you can drop it and return to that regulated rate, usually within one or two billing cycles — no fee to the utility.

How often does AES Ohio's power go out?

Federal reliability data, reported by the utility to the U.S. government. SAIDI is the average total time a customer is without power in a year; SAIFI is the average number of outages.

In 2024, including major storms

8 hr 23 min

without power, across about 1.3 outages

What the average customer actually experienced.

On a typical day (storms excluded)

1 hr 46 min

without power, across about 0.9 outages

Normal operations, with major event days removed.

For AES Ohio, major storms drove roughly 79% of 2024's total outage time — the gap between the two numbers above is weather the utility couldn't fully control.

On normal-day reliability, AES Ohio is the 3rd-most reliable of the 6 Ohio utilities we track — the range runs from 1 hr 35 min (Toledo Edison (FirstEnergy)) to 2 hr 38 min (AEP Ohio) of typical-day outage time per year.

How often does AES Ohio disconnect customers for nonpayment?

Utilities report this to the federal government. It counts residential service disconnected for unpaid bills. A high rate isn't proof of wrongdoing — it's shaped by local poverty, climate, and how strong a state's shutoff-protection rules are, as much as by the utility itself.

That's the 2nd-lowest disconnection rate of the 6 Ohio utilities we track — the range runs from 2.9 per 100 (Ohio Edison (FirstEnergy)) to 12.9 per 100 (AEP Ohio).

Where your bill money goes: how AES Ohio earns its profit

Because AES Ohio is a regulated monopoly, its profit isn't set by competing for customers — it's set by regulators. The PUCO authorizes a target return on equity (around 9.5% to 10.5% for U.S. electric utilities) on the money it sinks into poles, wires, substations, and meters. It's a target, not a guarantee — a utility can earn above or below it — but a low-risk regulated monopoly reliably lands close. You pay that return back, plus the investment itself, through the delivery charge on every bill.

AES Ohio is owned by The AES Corporation. In 2024, The AES Corporation reported about $1.7 billion in net income — its profit across all of the utilities it owns, not AES Ohio alone. Source: The AES Corporation's annual report (SEC Form 10-K, fiscal year 2024). SEC EDGAR →

That authorized return is set by regulators on the utility's investment — independently of how reliable the service is or how many customers are disconnected, the two measures above.

Rate cases & increases

  • 24-1009-EL-AIR effective

    AES Ohio (formerly Dayton Power & Light) filed a distribution rate review in November 2024 seeking roughly a 14% increase (about $21.75/month for a 1,000 kWh residential customer). PUCO approved a settlement Nov. 5, 2025 allowing ~$168 million in additional annual base distribution revenue; a typical 1,000 kWh residential bill rose about 9%.

Common questions about AES Ohio

What is AES Ohio's electricity rate per kWh?
AES Ohio's Standard Service Offer (SSO) — the default supply rate — is 10.86¢/kWh for the June 2026 – May 2027 delivery year, per PUCO's Apples to Apples. Unlike most Ohio utilities (now quarterly), AES's SSO holds for the full year. Delivery charges are additional, and PUCO approved a separate ~9% distribution increase (case 24-1009-EL-AIR). Verify the current SSO at energychoice.ohio.gov.
Why is my AES Ohio bill so high?
Two increases stacked: the auction-set SSO rose with the record PJM capacity results ($269.92/MW-day in 2024, then the $329.17 cap in 2025) to 10.86¢/kWh — Ohio's highest default supply rate — and PUCO separately approved AES Ohio's distribution case (24-1009-EL-AIR) at roughly +9% on the delivery side. The supply piece is a pass-through; the delivery piece is where AES earns its regulated return.
Should AES Ohio customers switch electricity suppliers?
Only if a fixed-rate offer genuinely beats AES Ohio's 10.86¢/kWh SSO — fixed for the June 2026 – May 2027 year, which makes the comparison unusually clean (no quarterly reset to guess about). Compare on PUCO's Apples to Apples at energychoice.ohio.gov — fixed rate below 10.86¢, no monthly fee, no cancellation penalty. Check your bill for an existing aggregation supplier first.

How Ohio deregulation works for AES Ohio customers

Ohio deregulated in 1999: AES Ohio delivers your power, and the supply side is competitive. The default Standard Service Offer (SSO) is 10.86¢/kWh, locked for a full year (June 2026 – May 2027) — unusual in Ohio, where most utilities now reset quarterly. After the July 2026 quarterly resets elsewhere, AES sits mid-pack rather than highest.

The flip side: AES Ohio customers also took a delivery-side hit. PUCO approved AES Ohio's distribution rate case (24-1009-EL-AIR) at roughly +9% on the delivery charge — separate from, and on top of, the auction-driven SSO increase. Supply is a pass-through with no markup; the distribution increase is the part AES earns a return on.
