IGS Energy reviews in Pennsylvania: a clean record, but a high price

Picture a scale. On one side is what IGS gives you: a long state record, a top BBB grade and no fines. On the other is what it costs: a price above your utility's default and a 30-day notice rule to leave.

The price side is the only light one. If IGS sold at exactly the price to compare, it would earn 15 points for price instead of 7. That would lift it to 81 points, a Very good score.

This tool does two jobs. It lists the IGS plans on PA Power Switch today, utility by utility. It also turns your contract end date into the dates that matter.

These are estimates, not a bill. The dates follow Pennsylvania's rules for fixed-price contracts, and your IGS contract and letters win if they differ. Plan prices come from the state's PA Power Switch list. Counts leave out our partner's plans.

Usually not. The price to compare is what your utility charges per kWh for supply if you do not shop. It is on your bill. On Oct 20, 2026, none of the IGS plans on the state's list cost less than it, in any of the seven areas where IGS sells. IGS says so itself in its contract: "Your supply price may or may not provide savings."

"Plans that cost less" counts fixed plans of 12 months or longer on the same utility's main home rate, by price per kWh. It leaves out our partner's plans. IGS costs more than at least 85% of them in every area. The tool above repeats this count live each day.

What the gap costs

Take a home that uses 700 kWh a month, or 8,400 kWh a year. This is one year of supply charges. Delivery charges are the same whoever supplies you, so they are left out.

That extra money buys one thing: a price that stays put. A fixed price pays off only if the price to compare ends up above it. At the last change, on June 1, 2026, the price to compare rose 1.5% to 11.9% in the seven big areas. IGS's gap is 11% to 27%. In every area, that gap is larger than the June 1 rise.

Check the price on IGS's own page

The state list and IGS's site do not always match. IGS sells a standard plan and a green plan that costs about 0.3¢ more. Three state cards match the green price, two match the standard price, and two are older and lower than both.

Check the price and the date on the card before you sign. Then check IGS's sign-up page for the same plan.

Yes. IGS is a licensed Pennsylvania electric supplier with a clean state record. The state approved its first license on May 19, 2011. Legit does not mean cheap, as the price section shows.

Here are the six parts of the 73. Each point comes from a public record or from IGS's own contract.

The license

The PUC's order of May 19, 2011 approved "Interstate Gas Supply, Inc. d/b/a IGS Energy" to sell electricity in PECO's area (docket A-2011-2228643). A license effective December 5, 2012 widened that to the seven big utility areas. The PUC reissued it on January 8, 2025 to Interstate Gas Supply, LLC. It lists PPL, PECO, Duquesne Light, Met-Ed, Penelec, Penn Power and West Penn. It does not list UGI Electric.

What the complaint report shows

The PUC counted 34 complaints that named IGS in 2024 and 58 in 2023. It does not adjust its counts for company size, so we do that step. IGS served 53,472 Pennsylvania homes in 2024, so the 2024 count is 6.36 per 10,000 homes. Of the 34, 28 named IGS as the main company.

The PUC warns that a high count "isn't necessarily indicative of a non-compliance issue," because suppliers vary in size. Its table also counts payment arrangement requests with consumer complaints. So treat 6.36 as a guide, not a verdict.

Fines, lawsuits and other states

We found no Pennsylvania fine, settlement or order against IGS. We also found no court ruling against its electricity plans. The one Pennsylvania court case we found names IGS as a petitioner. IGS, NRG and Shipley challenged PUC orders about utility on-bill billing. The Commonwealth Court upheld the PUC's orders on April 28, 2023. It is a dispute over utility billing, not over IGS's plans or customers.

Actions in other states are "reported, not scored." We found none against IGS on the Massachusetts DPU's list or in web searches. We did not search every state docket. A lawsuit is only a claim until a court decides it.

Why star ratings vary

Star ratings on open review sites can mix gas and electric customers, other firms' sales calls and anger at renewal prices. We do not use them. We use state records, the BBB grade and IGS's own contract.

What we could not check

IGS is private, so no audited financial statements are public. We read the PPL and PECO contracts and a 24-month PPL copy. Contracts for the other five areas may differ in small ways.

This review covers IGS's electricity plans for homes. IGS also sells natural gas, and we do not score that. We read its Pennsylvania contract (version V0826). All three copies share one template. Here are the terms that matter, in plain words.

Your plan ends after a set number of billing cycles, not on a calendar date. The first cycle can be partial. So the true end date can differ by a few days from the date you expect. Use the date on your IGS letter or in your online account.

A fixed plan ends on a set date. If you do nothing, IGS moves you to a monthly variable price. State rules make IGS warn you twice first.

1. 60 to 45 days before the endFirst notice. IGS tells you the plan is ending. It can come by mail or, if you chose it, by email.
2. At least 30 days before the endSecond notice, called the options notice. It must go by first-class mail. It lists three choices: stay, switch suppliers or go back to your utility.
3. From the second notice to the end dateNo cancel fee. PA Power Switch puts it as the last 30 days of your contract.
4. The end dateYour fixed price ends. IGS's contract then moves you to a monthly variable price.
5. After the end dateYou can leave at any time with no fee. IGS can change the price each month.

If you do nothing, the PUC says the supplier can move you to a month-to-month variable rate or to a fixed rate. Cancel fees do not apply then, and you can leave without penalty by telling the supplier. The supplier must tell you the price for the first billing cycle.

What IGS's monthly price looks like

IGS posts its monthly variable prices on its site. For October 2026 it posted 17.99¢ in six areas and 16.99¢ in PECO's. IGS says its posted prices are "not indicative of present or future pricing." Its contract says the price can change each month, based on energy and other costs "plus IGS Energy costs, expenses and margins."

At 1,000 kWh a month, 17.99¢ in PPL's area costs about $49 a month more than the price to compare, or about $589 a year. In PECO's area, 16.99¢ costs about $52 more a month, or about $628 a year.

IGS's posted prices move in steps. From July 2025 through May 2026 it posted 16.99¢ for PPL's area. Since June 2026 it posts 17.99¢. In PECO's area the price went from 14.99¢ to 16.99¢ in June 2026. Both rises came at the June 1 change in prices to compare. Another change comes December 1, so run the tool again after the new numbers post.

You do not need a reason to leave. You do need the right date. Follow these steps in order.

1. 1
   Find your end date and your fee.

   Look on your IGS bill, your contract or your online account. Then run the tool above. It turns your end date into your no-fee dates.

2. 2
   Pick where you go next.

   Choose a new supplier or go back to your utility's price to compare. PA Power Switch says switching back to your utility costs nothing. Read any new supplier's fee and renewal terms first.

3. 3
   Time the switch.

   Leave in the no-fee stretch and you owe no cancel fee. Leave earlier and IGS may bill $99, $149 or $199, depending on your plan. PA Power Switch says you can likely change suppliers in three business days once your utility is told of the switch.

4. 4
   Tell IGS.

   Call 800.280.4474, weekdays 8am to 8pm or Saturdays 9am to 3pm Eastern. Or write to IGS at P.O. Box 9060, Dublin, OH 43017. Ask for your last day of service and any fee, in writing. Your contract asks for 30 days' notice.

5. 5
   Check your last bill.

   Look for the end date and for any fee. If a fee looks wrong, use the complaint steps below.

IGS calls itself "private and family-owned" and says it has served customers "since 1989." It has no public audited financials, so we could not check its books.

We review three of those brands in Texas: Just Energy (Texas review), Amigo Energy (Texas review) and Tara Energy (Texas review). Those scores use Texas records. They do not change IGS's Pennsylvania score.

On Oct 16, 2026, IGS ranked tenth of 21 Pennsylvania suppliers. Its clean record puts it near the middle. Price keeps it from the top.

Read the last column as each supplier's 12-month plan against the price to compare. 100% means the same price. Under 100% means cheaper. See all 21 suppliers in our Pennsylvania supplier ranking, and read how we score.

Most problems end faster if you work through these steps in order.

1. 1
   Call or write IGS.

   The PUC asks you to try the company first. Use 800.280.4474 or CustomerSupport@igs.com. Write down the date, the time and the name of the person you spoke to.

2. 2
   If it is about a bill or a switch you did not approve, tell your utility too.

   A claim that your supplier changed without your consent counts as a dispute your utility must look into.

3. 3
   File an informal complaint with the PUC.

   Use the form at puc.pa.gov/complaints or call 800.692.7380. The PUC says an informal complaint "does not involve a legal proceeding."

4. 4
   Ask the Office of Consumer Advocate for help.

   It speaks for consumers in utility matters. IGS's contract lists its number as 800.684.6560.

Use 800.692.7380 for the PUC. That is the number on the PUC's own site. IGS's contract prints that number once and a different one, ending in 7390, once.
