Ohio Commercial Electricity 2026: AEP, Duke, FirstEnergy and the SSO Auction Explained
Ohio has one of the most active energy-choice markets in the country, and it works a little differently from other deregulated states. The default rate most Ohio businesses fall back on—the Standard Service Offer, or SSO—is set through competitive auctions rather than a single utility-set number, and Ohio's uniquely widespread governmental aggregation means many businesses are already buying power through a community program without realizing it. Understanding both is the key to knowing whether you are overpaying in 2026.
This guide explains how Ohio's SSO auction works, the major utilities and their territories, how governmental aggregation affects commercial accounts, why PJM capacity costs are pushing rates up, and the steps an Ohio business should take to shop competitively. It is written for owners and facility managers from Columbus to Cleveland to Cincinnati.

How Ohio's Energy-Choice Market Works
As in other deregulated states, an Ohio electric bill separates the regulated delivery service—owned by your utility—from the competitive generation (supply) service. Your distribution utility maintains the wires and delivers power no matter who supplies it. For the generation portion, you can take the utility's default Standard Service Offer, enroll with a competitive retail electric supplier (CRES), or be served through a governmental aggregation.
The Public Utilities Commission of Ohio (PUCO) oversees the market and runs the "Apples to Apples" comparison chart through its Energy Choice program, which lists CRES offers by utility. That tool, plus your Standard Service Offer price, gives you the benchmark to judge any supplier quote.
The Standard Service Offer (SSO) Auction
Ohio's default generation rate is not simply declared by the utility. Instead, each major utility procures the power for its default customers through a series of competitive wholesale auctions, and the blended results set the Standard Service Offer price. Because those auctions clear at different times and reflect prevailing market conditions, the SSO changes as new auction tranches roll in.
This design matters for two reasons. First, the SSO is genuinely market-linked, so it rises and falls with wholesale prices rather than staying flat. Second, because it is a blended average of multiple auction results, it can lag the current market—sometimes making a competitive fixed offer more attractive, sometimes less. The only way to know is to compare a real supplier quote against your current SSO on an all-in basis. Learning to read your commercial electric bill shows you exactly which line the SSO or supplier rate occupies.
Ohio's Major Utilities
| Utility | Primary Territory | Grid Operator |
|---|---|---|
| AEP Ohio | Columbus & central/southeastern Ohio | PJM |
| Duke Energy Ohio | Cincinnati & southwestern Ohio | PJM |
| FirstEnergy: Ohio Edison, Illuminating Co., Toledo Edison | Northern & northeastern Ohio (incl. Cleveland, Akron, Toledo) | PJM |
| AES Ohio | Dayton & the Miami Valley | PJM |
Every Ohio utility operates within PJM Interconnection. As in Pennsylvania and New Jersey, that means PJM's wholesale energy and capacity costs flow into both the SSO and competitive supplier pricing.
Governmental Aggregation: Ohio's Distinctive Wrinkle
Ohio is a national leader in governmental aggregation—programs in which a city, county, or township negotiates a group electricity rate on behalf of residents and small businesses in its jurisdiction, then enrolls eligible accounts (usually on an opt-out basis). If your business is in a community with aggregation, you may already be served through that program's supplier rather than the utility's SSO.
Aggregation can be a good deal, but it is not automatically the best deal for a commercial account, and larger businesses are often excluded from residential-style aggregation pricing. Two action items follow: first, confirm whether your accounts are enrolled in an aggregation and at what rate; second, compare that rate against a supply offer sized to your actual commercial load. A group rate designed for households will not necessarily reflect what your facility could secure on its own.
Why Ohio Rates Are Rising in 2026
Like every PJM state, Ohio is absorbing the effect of record capacity auctions. The 2026/2027 PJM capacity auction cleared near $329 per megawatt-day—roughly a 22% increase—and the following auction set another record. Capacity is what generators are paid to be available at peak, and that cost is embedded in both the SSO and competitive offers.
The drivers, documented by PJM and the U.S. Energy Information Administration, are rising demand (data centers and electrification), generation retirements outrunning new supply, and market volatility. For Ohio businesses, a rising default environment makes locking a well-timed fixed rate more valuable. Our PJM capacity auction guide explains the full mechanism, and our piece on AI data centers driving grid demand covers the demand side.
How Ohio Businesses Should Shop in 2026
- Identify your current supply. Determine whether you are on the SSO, a competitive supplier, or a governmental aggregation—and note the rate.
- Benchmark against the SSO and Apples-to-Apples. Your Standard Service Offer price and PUCO's comparison chart are the reference points every offer must beat.
- Pull 12 months of usage. Accurate interval data via a letter of authority lets suppliers price your true load.
- Compare like-for-like or run a live auction. Match term and contract structure, or use a reverse auction.
- Protect the renewal. Do not roll onto a holdover or default—see the auto-renewal trap.

Frequently Asked Questions
What is the Standard Service Offer in Ohio?
The Standard Service Offer (SSO) is the default generation rate you pay if you do not choose a competitive supplier or belong to an aggregation. Ohio utilities set the SSO through competitive wholesale auctions, so it is market-linked and changes over time. It is the benchmark every competitive offer should beat on an all-in basis.
Can Ohio businesses choose their electricity supplier?
Yes. Ohio is an energy-choice state, so commercial customers in AEP Ohio, Duke, FirstEnergy, and AES Ohio territories can buy generation from any certified competitive retail electric supplier while the utility delivers the power. PUCO's Apples-to-Apples chart lists offers by utility.
What is governmental aggregation and does it affect my business?
Governmental aggregation is a program where a city, county, or township negotiates a group electricity rate for eligible accounts in its area, often on an opt-out basis. Your business may be enrolled automatically. Confirm whether you are in an aggregation and compare that rate against a supply offer sized to your commercial load.
Why are Ohio electricity rates increasing in 2026?
The primary driver is record PJM capacity prices—about $329 per megawatt-day for 2026/2027, up roughly 22%—alongside rising demand from data centers, generation retirements, and volatility. These wholesale costs flow into both the SSO and competitive supplier offers.
Is Ohio's SSO a fixed rate?
No. The SSO is a blended result of competitive auctions and changes as new auction tranches take effect, so it is not a fixed rate you can rely on. A competitively sourced fixed contract can lock your generation cost and remove that exposure—compare the two before deciding.
Should a business leave its governmental aggregation?
Not automatically, but it is worth checking. Aggregation rates are designed for broad participation and may not reflect what your specific commercial load could secure independently, and larger accounts are sometimes excluded. Benchmark your aggregation rate against a tailored supplier quote before staying or switching.
Conclusion
Ohio's market gives commercial buyers real choice, but its two defining features—the auction-based Standard Service Offer and pervasive governmental aggregation—mean the "default" you are on may not be the best available. With record PJM capacity costs feeding into every rate in 2026, the businesses that come out ahead are the ones that identify their current supply, benchmark it against the SSO and real supplier offers, and lock a well-timed fixed rate before the next increase.
