Natural gas suppliers in Ohio

Ohio has four natural gas utilities — Columbia Gas of Ohio, Enbridge Gas Ohio, CenterPoint Energy Ohio and Duke Energy Ohio — and dozens of PUCO-certified suppliers competing to sell the gas they deliver. The default rate you pay if you never chose a supplier ranges from $0.3425 per Ccf at Enbridge to $1.037 at Duke, a threefold spread between two utilities in the same state. The complete certified supplier list is published free by the regulator at energychoice.ohio.gov; what it does not show you is the contract term, the cancellation fee, or what a promotional rate becomes after the promotion ends.

Start with your utility, not the supplier

Which suppliers can sell to you depends entirely on which utility delivers your gas, and the four default rates are not close to each other.

Utility	Default rate per Ccf	Effective	Territory
Enbridge Gas Ohio	$0.3425 (SCO)	August 11 – September 9, 2026	Cleveland, Akron and northeast Ohio
CenterPoint Energy Ohio	$0.4566 (SCO)	August 2026	Dayton and west central Ohio
Columbia Gas of Ohio	$0.4975 (SCO)	August 2026	Columbus, Toledo and much of central and western Ohio
Duke Energy Ohio	$1.037 (SSO)	Through October 31, 2026	Cincinnati and southwest Ohio

Duke is the outlier and it matters. It bills a Gas Cost Recovery rate under a Standard Service Offer rather than the Standard Choice Offer the other three use, and at $1.037 per Ccf its default runs roughly double Columbia's and triple Enbridge's. Anyone in Cincinnati comparing a supplier offer against a headline "Ohio gas rate" is comparing against a number they do not pay.

Where the certified supplier list lives

PUCO certifies every company allowed to sell retail natural gas in Ohio, and publishes the full list with each supplier's current offer for each utility. It is free, it is neutral, and no supplier pays to appear on it or to appear higher.

Open the PUCO supplier list

We do not reproduce a ranked version of that list here. Ranked lists of "best Ohio gas suppliers" are almost always ordered by what each supplier pays the site per enrollment, which makes the ordering a price the reader cannot see. The regulator's list is the one worth reading.

What to compare, beyond the rate

The rate is the number every comparison shows. These are the four that decide whether a rate is actually good, and most sites omit at least two of them.

What to check	Why it decides the outcome
Fixed or variable	A variable rate can open below the default and float above it from month two. The opening month is the pitch, not the product
What follows an introductory rate	Read the rate after the promo, because that is the one you will pay for most of the term
Contract term	A term signed in August runs through the winter that decides whether the bet paid off. Gas is seasonal in a way electricity is not
Early termination fee	Typically $50 to $200. It bounds how wrong the decision can go, and it is the number that makes switching out expensive
Ccf or Mcf	An Mcf is ten Ccf. An offer that looks ten times cheaper is a unit mismatch, not a deal

When staying on the default is the right answer

You are inside a fixed contract already, and the termination fee exceeds what a new rate would save before it expires.
You are on Enbridge. At $0.3425 per Ccf its default is currently low enough that many fixed offers do not beat it.
You value a predictable bill more than an expected saving. A fixed rate is insurance — you will beat the default in a cold winter and lose to it in a mild one, and that is the trade, not a discount.
You use more than 200 Mcf a year. Above that you are negotiating directly rather than shopping a published list.

Switching supplier never changes who delivers your gas, reads your meter or responds to a leak. That stays with the utility regardless of whose name is on the supply line.

Common questions

Who are the natural gas suppliers in Ohio?

Dozens of companies are certified by PUCO to sell retail natural gas in Ohio. The complete, current list is published by the regulator at energychoice.ohio.gov, organised by utility. Ranked lists on private sites are usually ordered by what each supplier pays per enrollment.

Which gas utilities serve Ohio?

Four: Columbia Gas of Ohio (Columbus, Toledo and much of central and western Ohio), Enbridge Gas Ohio (Cleveland, Akron and northeast Ohio), CenterPoint Energy Ohio (Dayton and west central Ohio) and Duke Energy Ohio (Cincinnati and southwest Ohio).

What is the cheapest natural gas rate in Ohio?

Among default rates, Enbridge Gas Ohio at $0.3425 per Ccf is currently the lowest and Duke Energy Ohio at $1.037 the highest — but you cannot choose your utility, only your supplier within it. Competitive offers should be compared against your own utility's rate, not against the cheapest one in the state.

Does switching gas supplier change who I call for a leak?

No. Your utility owns the pipes, reads the meter, responds to emergencies and sends the bill no matter who supplies the gas. Only the supply line on the bill changes.

Why is Duke Energy Ohio's gas rate so much higher?

Duke uses a Gas Cost Recovery rate under a Standard Service Offer rather than the auction-based Standard Choice Offer the other three utilities use. At $1.037 per Ccf it runs roughly double Columbia Gas and triple Enbridge, which also means competitive offers in Duke territory have more room to beat the default.

Do you get paid by gas suppliers?

No. We're paid by the customer, which is why there's no ranked supplier list on this page. A list ordered by commission is a recommendation the reader is paying for without being told the price.
