IGS Energy Review 2026: Plans, Pricing, and How It Compares

IGS Energy is one of the largest private retail energy companies in the United States, serving residential and commercial customers in Ohio, Pennsylvania, New York, New Jersey, Maryland, Virginia, and other deregulated markets. Unlike the publicly traded giants, IGS operates as a privately held company — a fact it uses as a marketing point around customer-focused service. This review covers IGS Energy’s plans, pricing, customer ratings, and whether it’s worth considering in 2026.

About IGS Energy

IGS Energy (Interstate Gas Supply, Inc.) was founded in 1989 and is headquartered in Dublin, Ohio. It’s one of the few large retail energy suppliers that remains privately owned, which the company argues allows it to focus on long-term customer relationships rather than quarterly earnings. IGS serves approximately 500,000 residential and commercial customers across more than a dozen deregulated states.

Beyond retail electricity, IGS also operates in the natural gas supply market and has solar energy and energy efficiency divisions. If you want a single supplier for both gas and electricity, IGS is one of the few retail providers that offers bundled residential energy accounts.

IGS Energy Plan Types

Fixed-Rate Electricity Plans

IGS’s core residential offering is fixed-rate electricity, available in 12, 18, and 24-month terms depending on your state and utility territory. Fixed rates protect you from market volatility for the contract duration. IGS typically positions its fixed-rate pricing slightly above the lowest-cost provider in any given market, competing on service quality and stability rather than rock-bottom price.

Variable-Rate Plans

IGS offers variable-rate plans in most markets for customers who want flexibility without a long-term commitment. Like all variable plans, rates float monthly with wholesale market conditions. IGS does not publicize its variable pricing in advance — you’ll know the rate when your monthly statement arrives.

Green Power Plans

IGS offers green electricity options backed by renewable energy certificates (RECs) sourced from wind and solar projects. The availability and pricing of green plans varies by state. In Ohio and Pennsylvania, green add-on options are commonly available on top of standard fixed-rate plans.

Commercial Energy Plans

IGS has a significant commercial and industrial (C&I) customer base. For small business owners, IGS offers fixed and indexed commercial plans with account management support — a differentiator versus consumer-focused REPs that don’t invest heavily in B2B service.

IGS Energy Pricing in 2026

IGS’s residential electricity rates are competitive but not typically the lowest in any market. In 2026, approximate all-in rates for a standard 1,000 kWh/month household:

• Ohio (AEP Ohio/Duke/FirstEnergy): 9–11 cents/kWh for 12-month fixed plans
• Pennsylvania (PECO/PPL territory): 9–12 cents/kWh depending on territory and contract length
• New Jersey (PSE&G/JCP&L territory): 10–13 cents/kWh for fixed residential plans
• Maryland (BGE/Pepco territory): 9–12 cents/kWh for standard fixed plans

These ranges are illustrative — current offers change frequently. Use a rate comparison platform to see IGS’s live offers against your local utility’s price-to-compare rate.

IGS Energy Customer Service and Satisfaction

IGS consistently scores above average on customer satisfaction for a regional retail supplier. The privately owned structure does appear to translate into a more accessible customer service experience — customers report shorter hold times and more empowered representatives compared to large publicly traded suppliers. IGS has an A+ BBB rating and relatively few formal utility commission complaints per customer served.

A notable strength: IGS’s online account management and billing portal are cleaner and more functional than several larger competitors. The ability to see your rate, contract end date, and renewal options clearly displayed in the account portal reduces the confusion that fuels complaints at other REPs.

IGS Solar

IGS operates a solar division (IGS Solar) that installs residential solar systems. If you’re interested in adding solar alongside your electricity supply contract, IGS is one of the few retail suppliers that can offer both services under the same company umbrella. This integrated approach appeals to homeowners who want a single point of contact for their electricity needs.

IGS vs Competitors

• IGS vs Constellation: Constellation is a larger, more nationally present supplier. In mid-Atlantic and midwest markets, Constellation often wins on price for multi-year fixed contracts. IGS tends to edge out on customer service scores and contract flexibility.
• IGS vs NRG: NRG has broader national presence and the Green Mountain renewables subsidiary. For customers in Ohio and Pennsylvania who value regional expertise, IGS’s home-state advantage is meaningful.
• IGS vs Direct Energy: Direct Energy and IGS compete directly in several northeast and midwest markets. Direct Energy is more aggressive on promotional pricing; IGS trades on stability and service quality.

Is IGS Energy a Good Choice?

IGS is a strong option for customers in Ohio, Pennsylvania, and mid-Atlantic markets who prioritize reliable service, transparent billing, and a supplier that will still be operating in five years. It’s a particularly good fit for small business owners who want dedicated account support. If your only criterion is the lowest possible rate, you’ll often find cheaper options by shopping comparison platforms. But if service quality, contract transparency, and stability matter to you, IGS deserves a spot in your comparison set.

Frequently Asked Questions

Is IGS Energy a reputable company?

Yes. IGS Energy has been operating since 1989 and is one of the largest privately held retail energy companies in the US. It holds an A+ BBB rating and has a strong track record in its core markets (Ohio, Pennsylvania, mid-Atlantic states).

What states does IGS Energy serve?

IGS Energy serves customers in Ohio, Pennsylvania, New York, New Jersey, Maryland, Virginia, Illinois, Indiana, Michigan, and several other deregulated states. Availability varies by utility territory within each state.

Does IGS Energy have early termination fees?

Most IGS fixed-rate residential plans include an early termination fee (ETF), typically in the $75–$150 range depending on your plan and state. Variable-rate plans generally have no ETF. Always check your supply agreement for the exact terms.

Can I get both gas and electricity from IGS?

Yes. IGS operates in both natural gas and electricity retail markets. In many of its service states, you can bundle both commodities under a single IGS account, simplifying your energy supplier management.

How does IGS handle contract renewals?

IGS sends renewal notices before your fixed-rate contract expires. If you don’t act, you’ll typically roll to a variable-rate plan at market pricing. IGS has a better-than-average reputation for clear renewal communications — but still set a calendar reminder 45 days before your contract end date to shop the market actively.

Does IGS offer renewable electricity?

Yes. IGS offers green electricity plans backed by renewable energy certificates (RECs) in most of its service states. These are typically available as an add-on to standard fixed-rate plans or as standalone green products at a small premium.
