Hamilton Ohio Utility Companies: Electric Rates Guide 2026

A homeowner on South Front Street in Hamilton opens her July bill and sees a line labeled "Price to Compare" near the top. That number is the key to understanding whether she is overpaying for electricity, and it all starts with knowing which company delivers power to her address.

Hamilton, Ohio is served by AES Ohio (formerly Dayton Power and Light). AES Ohio is a regulated electric distribution utility, meaning it owns and maintains the poles, wires, and meters that bring power to homes and businesses across the greater Dayton and southwest Ohio region. The Public Utilities Commission of Ohio (PUCO) sets the rules AES Ohio must follow, including the rates it can charge customers who stay on default supply.

The city of Hamilton does not operate its own municipal electric system for residential customers. Delivery of electricity, outage response, and meter reading all run through AES Ohio. What residents can choose is their electricity supplier, the company that actually generates or procures the power flowing through those AES Ohio wires.

Every AES Ohio customer who has not shopped for a competitive supplier automatically buys electricity at the Standard Service Offer rate. The PUCO requires AES Ohio to print this as the Price to Compare on every bill, specifically so customers can evaluate competing offers against it.

As of July 2026, the AES Ohio default supply rate sits at approximately 9.4 cents per kWh. That figure covers only the supply (generation) portion of the bill. Delivery charges, transmission costs, and various riders are separate line items that every customer pays regardless of supplier.

For a household using 900 kWh in a month, the supply portion at the default rate works out to roughly $84.60 before delivery and other fixed charges are added. The total bill will be higher once distribution and miscellaneous fees are included, but the supply rate is the piece a shopper can actually change.

It is worth noting that the default rate is not fixed forever. PUCO reviews and adjusts it periodically, so the number on a bill today may differ from what appears six months from now. Check ElectricRates.org's Ohio page for the most current figures before making any supplier decision.

Ohio deregulated its electricity market in the early 2000s, giving residential and commercial customers the legal right to buy their electricity supply from a licensed competitive retail electric service (CRES) provider rather than from the utility itself. The utility still delivers the power, reads the meter, and handles outages. Only the supply procurement changes.

The PUCO oversees competitive suppliers and maintains licensing requirements to protect consumers. Ohio's official comparison tool is Energy Choice Ohio, sometimes called the "Apples to Apples" chart. It lists every licensed supplier offering service in a given utility territory, along with their rate, contract length, cancellation terms, and whether the rate is fixed or variable.

The process for Hamilton residents is straightforward. A customer visits Energy Choice Ohio, selects AES Ohio as their utility, and reviews available offers. If they find a rate below the current Price to Compare, they can enroll directly with that supplier. AES Ohio continues delivering power and billing for delivery charges. The supplier change typically takes effect within one to two billing cycles, and customers can switch back to the default service if they choose, though early termination fees may apply depending on the contract.

The spread between what a shopper can find and what the default charges can be meaningful. As of July 2026, the lowest competitive supplier rates available in Ohio reach approximately 7.6 cents per kWh in some territories, including AES Ohio service areas. Compared to the 9.4-cent default, that gap represents real money over a year.

Consider a Hamilton household averaging 800 kWh per month. At the default 9.4 cents, annual supply costs come to roughly $902. At a competitive rate near 7.6 cents, the same usage brings annual supply costs down to around $730. The difference, about $172 per year, does not require any lifestyle change or efficiency upgrade. It just requires spending twenty minutes on Energy Choice Ohio.

That said, not every offer on the market beats the default. Variable-rate plans in particular can start low and rise sharply when wholesale power prices spike. A fixed-rate contract offers predictability; a variable rate does not. Hamilton residents should read the full offer terms, including the contract length and any cancellation penalties, before enrolling with any supplier.

Ohio has several investor-owned utilities, each with its own PUCO-approved default supply rate. Knowing where AES Ohio stands relative to the others gives Hamilton residents useful context.

As of July 2026, the default supply rates across the state's major utilities break down as follows:

Ohio Edison: ~9.3 cents/kWh
AES Ohio: ~9.4 cents/kWh
The Illuminating Company: ~9.5 cents/kWh
Toledo Edison: ~9.7 cents/kWh
Duke Energy Ohio: ~10.1 cents/kWh
AEP Ohio: ~10.7 cents/kWh

AES Ohio's default sits toward the lower end of that range, which is modestly good news for Hamilton customers. Still, the 7.6-cent competitive floor available in some territories means shopping can produce savings even from an already-below-average starting point. Customers of AEP Ohio or Duke Energy Ohio, whose defaults are considerably higher, may find the savings opportunity even larger.

Rate comparisons matter most to households with tight budgets, and Ohio has programs specifically designed to help income-qualified customers lower their electric costs.

PIPP (Percentage of Income Payment Plan) is administered through the PUCO and caps monthly electric payments at a percentage of a household's gross income. Eligible customers make reduced payments, and the remaining balance is forgiven over time as long as they stay current. PIPP eligibility is generally tied to household income relative to the federal poverty guidelines, but the exact thresholds should be confirmed directly with the PUCO or a local community action agency, as they are adjusted periodically.

HEAP (Home Energy Assistance Program) is a federally funded program administered in Ohio through the Ohio Development Services Agency. HEAP provides one-time or seasonal bill credits to income-qualified households. Butler County residents, including those in Hamilton, can apply through the local community action agency.

AES Ohio also offers its own customer assistance options; calling AES Ohio's customer service line or visiting their website is the best way to see what is currently available. These programs stack on top of any savings from competitive suppliers, so they are not mutually exclusive.

One of the most practical things a Hamilton resident can do is learn to read the AES Ohio bill before shopping for a supplier. The bill separates supply from delivery clearly, and that separation is the foundation of the whole choice process.

The Price to Compare line, typically found in the generation or supply section, is the current rate in cents per kWh that AES Ohio charges for default supply. Any competitive offer must be compared to this number, not to the total bill, because delivery charges will remain the same regardless of supplier.

Other line items include distribution charges (for maintaining the local grid), transmission charges (for moving power from generators to the region), and various riders tied to regulatory mandates or infrastructure investments. None of these change when a customer enrolls with a competitive supplier.

If the bill shows a supplier name other than AES Ohio in the supply section, the customer has already enrolled in competitive service. The rate shown there is what that supplier is currently charging. It is worth comparing that number to the current Price to Compare, especially if the original contract has expired and the account has rolled onto a variable month-to-month rate.

Shopping for electricity in Hamilton is not complicated, but a few habits prevent the common mistakes.

Start with Energy Choice Ohio. The PUCO-maintained Apples to Apples chart is the most reliable single source for comparing licensed suppliers. It filters by utility territory and shows offer details in a standardized format, making it easier to compare offers side by side.

Favor fixed rates for predictability. A fixed rate locks in your supply cost for the contract term, insulating you from wholesale price swings. Variable rates can fall below fixed rates at times, but they can also spike well above the default during periods of high demand or tight supply.

Check the contract length and exit terms. A two-year fixed rate is a different commitment than a six-month introductory offer. Know what happens if you move, sell the home, or simply want to switch suppliers mid-contract.

Do the math on your actual usage. Pull three to four recent AES Ohio bills and note your average monthly kWh. Apply both the default rate and any competitive offer to that real number to estimate actual savings, not hypothetical ones.

Revisit your rate annually. Competitive offers expire. A rate that was the best deal eighteen months ago may have rolled to a higher variable rate. Setting a calendar reminder to recheck Energy Choice Ohio once a year takes five minutes and can prevent unpleasant billing surprises.

Hamilton residents covered by AES Ohio have a straightforward path to potentially lower electric bills. The AES Ohio default supply rate stands at approximately 9.4 cents per kWh as of July 2026. Competitive offers available in the territory can reach as low as 7.6 cents per kWh, though specific offers change frequently.

The PUCO's Energy Choice Ohio comparison tool is the right place to start, and checking back periodically ensures you are always on the best available rate for your household. Assistance programs through PIPP and HEAP exist for income-qualified customers and are worth exploring regardless of whether you shop for a competitive supplier.
