AES Ohio rates and bills: The Dayton Power and Light Company
AES Ohio's 142,651 default-service customers in Ohio paid an average of 16.12¢ per kWh in 2025, for an average bill of $158.08 a month on 980 kWh.1 Over the last 12 months (Sep 2025–Aug 2026) the average was 18.80¢, and 20.62¢ in August 2026.2 Another 326,666 homes on its wires (69.6%) buy their supply elsewhere and pay AES Ohio delivery charges averaging 7.07¢ per kWh, plus their supplier's price.
EIA-861 2025 final (released October 7, 2026) and EIA's monthly utility survey through August 2026 (preliminary); next monthly update expected November 24, 2026. Averages are revenue divided by kWh, all charges included: not the rate printed in a tariff.
24 of 88 Ohio counties served (EIA-861 2025)
The average AES Ohio default-service bill rose +12.7% from 2024 to 2025, against +5.2% for the price per kWh, because homes also used more electricity. Delivery charges for the 326,666 homes that buy supply elsewhere rose +18.4%1 per kWh, and new distribution rates approved by Ohio's utility commission took effect in November 2025.
What AES Ohio's default-service homes paid per kWh
AES Ohio is the trade name of The Dayton Power and Light Company, which carries electricity across West Central Ohio. In its 2025 annual report to the SEC the company describes itself as a transmission and distribution utility, and Dayton Power and Light remains the legal name on EIA's records.
Homes that bought both delivery and supply from AES Ohio, its default or Standard Service Offer customers, paid an average of 16.12¢ per kWh in 2025. That placed it 12th lowest among the 27 Ohio utilities with 10,000 or more such customers, 4.6% below the Ohio average and 9.3% below the national average for investor-owned utilities. Among US utilities with 100,000 or more residential customers it ranked 72nd highest of 1771.
The figure is average revenue per kWh: everything those homes were billed, divided by what they used. It folds in the monthly customer charge and the riders, so it does not match any single line of the tariff, and a small user pays more per kWh than a large one.
EIA's monthly survey, which samples AES Ohio every month, shows a higher level since then. Over the 12 months September 2025 to August 2026 the average was 18.80¢ per kWh. In August 20263 it reached 20.62¢ per kWh, +13.1%2 on the same month a year earlier. Months from January 2026 are preliminary, and a single month carries its season, so the 12-month figure is the steadier reading.

Why the 2025 bill rose faster than the price
A bill is price times use, and both moved at AES Ohio in 2025. The default-service average rose from 15.32¢ per kWh to 16.12¢ per kWh (+5.2%), while use per home climbed from 915 kWh to 980 kWh a month. Together they lifted the average monthly bill from $140.244 to $158.08, a +12.7%1 change.
The rest of Ohio's investor-owned utilities moved differently in 2025. Default-service bills rose +3.2% at AEP Ohio, +3.4% at Ohio Edison, +3.3% at Toledo Edison, and changed −0.2% at The Illuminating Company; only Duke Energy Ohio, at +15.6%, saw a larger rise than AES Ohio. AES Ohio's default-service homes also used more electricity than those of any of the five (944 kWh at AEP Ohio, 636 kWh at The Illuminating Company), so a price below the Ohio average still produced a bill that trailed only AEP Ohio's $179.101 among the six.

| Toledo Edison (OH) | $127.14 |
| Ohio Edison (OH) | $131.45 |
| Duke Energy Ohio (OH) | $154.05 |
| AES Ohio (OH) | $158.08 |
| AEP Ohio (OH) | $179.10 |
The 12 months to August 2026 point the other way on use: 931 kWh a month, below the 2025 level. The 12-month bill still came to $175.032, so the price per kWh, not use, drove that later increase.
The November 2025 distribution rate order
AES Ohio's distribution rates are set by the Public Utilities Commission of Ohio. According to the same SEC filing, the commission approved a settlement of the company's distribution rate case on November 5, 2025, and the new rates and charges took effect on November 6, 2025. That date falls inside the 12-month window above, but EIA's averages do not separate one order's effect from fuel, supply and rider changes.
The filing also records that, to comply with a state law, AES Ohio applied on November 10, 2025 for a Three-Year Rate Plan, proposing distribution rates for 2027, 2028 and 2029; when the report was filed in March 2026, a commission order was expected by the end of 2026. The guide to rate increases shows how such a decision reaches the bill.
Delivery-only homes: the lowest delivery average, rising fastest
Most homes on AES Ohio's wires do not buy their electricity from it. Of the 469,317 residential customers it served in 2025, 69.6% bought supply from a competitive supplier or a community aggregation and paid AES Ohio for delivery only; 142,6511 stayed on default service.
The delivery-only homes paid AES Ohio an average of 7.07¢ per kWh in 2025, up from 5.97¢ per kWh4 in 2024 (+18.4%). That is the utility's part of their bill, $69.27 a month on average; their supplier charges for the energy at a price EIA does not report by utility, and the two parts are not added here. At the other investor-owned utilities the delivery-only average was 7.42¢ per kWh at Ohio Edison (+1.6%), 7.71¢ per kWh at The Illuminating Company (−1.3%), 7.89¢ per kWh at Toledo Edison (+1.0%), 8.17¢ per kWh at Duke Energy Ohio (+4.6%) and 10.26¢ per kWh at AEP Ohio (−4.6%1), all changes from 2024 to 2025.
Supplier offers for the AES Ohio area are listed by the state on Energy Choice Ohio. An offer covers supply only, so it compares with the supply part of AES Ohio's Standard Service Offer, not with the 16.12¢ per kWh1 default-service average, which also contains delivery. The Ohio retail choice guide explains the comparison.
January brings the largest bill
AES Ohio's monthly data put the peak in winter. Over the 12 months September 2025 to August 2026, use per default-service home ranged from 660 kWh in April 2026 to 1,397 kWh in January 2026, and the average bill in those two months from $137.09 to $241.83. A household budgeting on the 12-month average of $175.032 a month will see its January bill well above it.

Next to AES Indiana
The AES Corporation's 2025 annual report lists two US utilities: AES Ohio, a transmission and distribution utility, and AES Indiana, which also generates power. They are close in size, 469,317 and 469,6341 residential customers in 2025, but EIA reports no delivery-only residential customers at AES Indiana: every home on its wires buys full service from it.
AES Indiana's homes paid an average of 14.69¢ per kWh in 2025 (+6.8% on 2024) and 15.43¢ per kWh2 over the 12 months September 2025 to August 2026; its average bill was $138.29 for 941 kWh1 a month. The two answer to different state commissions, and one generates power while the other only delivers it, so the gap describes 2025 and predicts nothing for either.

Outages, smart meters and rooftop solar
AES Ohio customers averaged 168 minutes without power in 2025 including major event days, fewer than the Ohio average of 205 minutes, and 96 minutes excluding major event days, with 0.99 interruptions per customer (IEEE 1366 measures). AES Indiana's customers averaged 295 minutes5 on the same all-events basis.
Advanced meters made up 92.4% of AES Ohio's residential meters in 2025. Rooftop solar is rare: 474 net-metered residential installations, 1.0 per 1,000 customers, with 3.9 megawatts6 of capacity.
Businesses buy supply elsewhere too
The split between default service and suppliers is wider for businesses. In 2025, 10,335 commercial customers took full service from AES Ohio and paid 14.18¢ per kWh on average, while 47,589 took delivery only, at 3.57¢ per kWh for that part of their bill. Only 114 industrial customers were on full service (13.17¢ per kWh), against 1,366 on delivery only (1.88¢ per kWh1). Full-service and delivery-only averages cover different parts of the bill and cannot be compared directly.
Counties served and help with bills
EIA's service-territory file lists AES Ohio in 24 Ohio counties: Auglaize County, Brown County, Butler County, Champaign County, Clark County, Clinton County, Darke County, Delaware County, Fayette County, Greene County, Hardin County, Highland County and 12 others. In all 247 at least one other utility also reports customers, so a town or ZIP code does not settle which utility serves a home; AES Ohio's own service map does, by address. For the state picture, see electricity in Ohio.

AES Ohio and Dayton Power and Light questions
Is AES Ohio the same company as Dayton Power and Light?
Yes. The utility's legal name is The Dayton Power and Light Company, and it does business as AES Ohio; EIA lists it as The Dayton Power and Light Company (AES Ohio). It is a subsidiary of The AES Corporation, which also owns AES Indiana.
What is AES Ohio's rate per kWh?
EIA does not publish tariffs; it publishes what customers paid on average. Default-service homes paid 16.12¢ per kWh1 in 2025, 18.80¢ per kWh over the 12 months September 2025 to August 2026, and 20.62¢ per kWh2 in August 20263 (preliminary). Each is total residential revenue divided by kWh, so it includes the customer charge, delivery, supply and riders.
What is the average AES Ohio electric bill?
$158.08 a month in 2025 for default-service homes using 980 kWh1, and $175.03 over the 12 months September 2025 to August 2026. In EIA's monthly data the highest month was January 2026 at $241.832.
Why did my AES Ohio bill go up?
EIA's figures show averages, not individual accounts. On average, a default-service bill went from $140.24 in 2024 to $158.08 in 2025: the price per kWh rose 5.2% and use per home rose from 915 kWh4 to 980 kWh1 a month. New distribution rates took effect on November 6, 2025, after an order by the Public Utilities Commission of Ohio.
