IGS Energy Reviews: Ohio Customers Rate the Supplier (2026)

A Columbus, Ohio family came home one evening to a door-to-door sales rep offering to lower their electric bill through a company called IGS Energy. They signed on the spot. Six months later, one sibling swore by the savings; the other had quietly switched back to their utility. Same company, very different outcomes, and those two experiences show up again and again in online reviews.

IGS Energy (Interstate Gas Supply) is headquartered in Dublin, Ohio and has operated as a retail energy marketer in the state for decades. It sells electricity supply to residential and small commercial customers across most Ohio utility territories, including AEP Ohio, Duke Energy Ohio, Ohio Edison, The Illuminating Company, Toledo Edison, and AES Ohio. The company is licensed and overseen by the Public Utilities Commission of Ohio (PUCO), which means it must follow state consumer-protection rules covering contract disclosures, cancellation rights, and billing practices.

Aggregate ratings for IGS Energy on consumer platforms tend to cluster around three recurring themes.

Positive reviews most often come from customers who enrolled in a fixed-rate plan during a period when the utility's Standard Service Offer was elevated. These customers locked in a set cents-per-kWh rate, watched their supply charge stay flat through winter price spikes, and felt they had made a smart move. They also mention that enrollment was quick and that the utility still handles delivery and billing, so the experience felt familiar.

Negative reviews concentrate on two situations. First, customers who started on a promotional rate that later rolled to a variable rate report bill shock when that variable rate climbed well above their utility's Price to Compare. Second, some customers describe difficulty canceling or say they did not fully understand the contract term before signing. PUCO rules give Ohio customers a three-day right to rescind a supplier agreement without penalty, but some reviewers say they did not know that window existed.

Neutral or mixed reviews often come from customers who saved for a while and then saw their rate rise at renewal. The underlying frustration is usually about communication: they wanted a clear renewal notice before being auto-renewed or rolled to a new rate.

The pattern is consistent with competitive-supplier markets broadly. The product itself is commodity electricity; the difference between a good and bad experience usually comes down to whether the rate offered at enrollment was genuinely below the Price to Compare, and whether the contract terms were fully explained.

Ohio deregulated its electricity market, which means residential customers in most of the state can choose who supplies their electricity. The utility (AEP Ohio, Duke Energy Ohio, AES Ohio, Ohio Edison, Toledo Edison, or The Illuminating Company) still owns the wires and delivers power to your home. That delivery charge does not change no matter which supplier you pick. What changes is the supply portion of your bill.

If you do nothing, your utility serves as your default supplier through what Ohio calls the Standard Service Offer. The price for that default supply is called the Price to Compare, and it appears on your bill each month. That number is your baseline. Any competitive supplier offer worth taking should beat it, at least over the life of the contract.

As of August 2026, default supply rates across Ohio utilities look like this:

The lowest competitive supplier rate available in the state as of August 2026 is around 7.6 cents/kWh, though availability varies by territory. An IGS Energy fixed-rate quote that comes in below your utility's Price to Compare is potentially worth taking. One that comes in above it is not, regardless of how the sales pitch frames it.

The process is straightforward, though many customers skip it.

Step 1: Find your Price to Compare. Pull up your most recent electric bill. Most Ohio utilities print the Price to Compare clearly, usually labeled exactly that way. It is expressed in cents per kWh and covers only the supply portion.

Step 2: Get IGS's specific offer in writing. Ask for the rate in cents per kWh, whether it is fixed or variable, the contract term in months, any early termination fee, and what happens at the end of the term. A reputable supplier will hand you all of this in a disclosure document before you sign.

Step 3: Use Energy Choice Ohio. The state-run comparison tool, commonly called the Apples to Apples comparison chart at energychoice.ohio.gov, lists every PUCO-licensed supplier offering service in your utility territory, along with their current rates and contract terms. Look up IGS's current offers there alongside competitors. If IGS's rate is not the lowest fixed-rate option available in your territory, you may be leaving money on the table.

Step 4: Do the math for your usage. Take your average monthly kWh usage (also on your bill) and multiply it by the difference between IGS's quoted rate and your Price to Compare. That tells you your monthly savings or cost in real dollars, not percentages.

IGS Energy has historically offered both fixed-rate and variable-rate plans, and understanding the difference is critical for interpreting reviews accurately.

A fixed-rate plan locks your supply rate for a set number of months. Your bill will still fluctuate because you use more or less electricity, but the per-kWh rate stays constant. This is the plan most people think they are signing up for when they read a positive IGS review.

A variable-rate plan adjusts monthly based on market conditions. In a low-price environment, variable rates can be attractive. During cold snaps or grid stress events, they can spike significantly above the utility's Standard Service Offer. Many of the negative IGS reviews come from customers who were on variable plans and were not fully aware of that fact.

PUCO rules require suppliers to disclose whether a rate is fixed or variable, but the disclosure is sometimes buried in contract language. Before enrolling with any supplier, confirm in writing which type of plan you are signing, the exact rate, and the exact term.

Ohio law gives customers meaningful protections when dealing with competitive suppliers, and knowing them matters whether you are considering IGS or any other marketer.

Three-day right to rescind. After signing a supplier agreement, you have three business days to cancel without penalty. This applies to contracts signed at the door, over the phone, or online. If you feel pressured into signing, use this window.

Early termination fees. Fixed-rate contracts often include an early termination fee if you cancel before the term ends. The amount must be disclosed upfront. Variable-rate plans typically have no ETF because there is no set term.

Automatic renewal. Some contracts renew automatically at the end of the term. PUCO rules require the supplier to notify you before an automatic renewal takes effect, but the notification window can be short. Mark your contract end date and set a calendar reminder to reassess.

Filing a complaint. If you believe a supplier has violated Ohio rules, you can file a complaint directly with PUCO. The commission mediates disputes between customers and licensed suppliers and has the authority to investigate and sanction companies.

For assistance with bills, lower-income Ohio households may also qualify for programs like HEAP (Home Energy Assistance Program) or PIPP (Percentage of Income Payment Plan), administered through the Ohio Development Services Agency. Contact PUCO or your utility for eligibility details.

The short answer is no. IGS Energy is a licensed competitive electric supplier regulated by PUCO. It is not a scam in the legal sense. The company has been operating in Ohio for a long time and has served a large number of customers.

That said, some practices that generate negative reviews, including aggressive door-to-door sales, promotional rates that roll to higher variable rates, and auto-renewal clauses, are legal but create customer frustration. Those practices are not unique to IGS; they appear across the competitive supplier market.

The better question is whether a specific IGS offer makes financial sense for a specific customer at a specific moment. That answer changes based on your utility territory, current market prices, and the exact terms being offered. A blanket "IGS is great" or "IGS is a rip-off" verdict misses the point. The Price to Compare on your bill is the only honest benchmark.

Ohio's deregulated market includes many licensed suppliers beyond IGS. The Apples to Apples comparison on the Energy Choice Ohio website lists all of them, filterable by utility territory and rate type. That is the most reliable starting point because every offer listed there has been submitted to PUCO.

A few things to keep in mind when comparing:

As of August 2026, the gap between the highest default supply rate in Ohio (around 11.2 cents/kWh with The Illuminating Company) and the lowest available competitive rate (around 7.6 cents/kWh) is meaningful for a household that uses several hundred kWh per month. Whether IGS Energy fills that gap better than another supplier depends entirely on what is on the table in your territory right now.
