The bottom line
IGS Energy is a legitimate regional supplier with substantial market presence. The electricity supply business is separate from the solar installation division that generates most online complaints. If you actively chose IGS Energy for electricity (rather than being approached for a solar pitch), you'll likely find standard mid-range service. The "proceed with caution" rating reflects the customer service score being dragged down by solar division complaints and the fact that other PA suppliers offer better pricing.

IGS Energy vs IGS Solar: understanding the complaints
If you're researching IGS and seeing concerning reviews, it's important to understand what business those complaints are actually about.
IGS Energy
Retail electricity and natural gas supply. You enroll online or by phone, choose a plan, and receive supply through your existing utility. Standard competitive retail energy business.
Few complaints specific to electricity supply
IGS Solar
Solar panel installation division. High-ticket sales ($20,000+) pursued through door-to-door canvassing and aggressive sales tactics.
Source of most online complaints
Online discussions about "IGS Energy scams" typically reference door-to-door solar sales experiences, not electricity supply issues. If you're considering IGS specifically for electricity supply, the solar complaints are less relevant — though they do reflect on the parent company's overall sales culture.
If you were approached at your door
If someone knocked on your door offering solar panels or energy services, take time to research independently. Never sign anything at the door. Get quotes from multiple solar installers. For electricity supply, compare rates online at your own pace. See our guide on how to avoid electricity scams.
Who is IGS Energy?
IGS Energy (Interstate Gas Supply, Inc.) was founded in 1989 and is headquartered in Dublin, Ohio. The company started as a natural gas supplier and expanded into electricity supply as states deregulated their energy markets.
IGS is privately held by IGS Inc. — not part of a large utility holding company like some competitors. The company operates across multiple states including Pennsylvania, Ohio, Indiana, Michigan, and Kentucky.

Pros and cons
What we like
- Established regional company with 35+ years of operation
- Multi-state presence offers consistency if you move

- Green energy plan options available

What concerns us

- Mid-range pricing — competitors often beat IGS on rates
- Privately held = less financial transparency
- Door-to-door sales culture raises questions about company priorities
Detailed analysis
Pricing (3.0/5)
IGS Energy's rates in Pennsylvania typically fall in the middle of the market. They're not the most expensive supplier, but they're also not competing on lowest price.
For customers who prioritize cost above all else, smaller regional suppliers like Public Power often offer better rates. IGS may make more sense for customers who value multi-state presence or want both electricity and natural gas from one supplier.
Plan diversity (3.0/5)
IGS offers a standard range of plan types: fixed-rate at various term lengths, variable-rate options, and green energy plans. The portfolio is adequate but not exceptional compared to national suppliers with deeper plan menus.
Transparency (3.0/5)
IGS meets standard disclosure requirements. Plan Information Documents are available and contain required rate and term information. Nothing notably better or worse than typical regional suppliers.
Customer service (2.5/5)
This is where IGS loses points, though context matters. Most online complaints involve the solar division rather than electricity supply. However, the volume of solar complaints and the door-to-door sales culture reflects on the overall company.
For customers specifically using IGS for electricity supply, the experience may be better than reviews suggest — but the brand reputation drag is real.
Green options (3.0/5)
IGS offers green energy plans backed by RECs, plus operates a solar installation division for customers interested in rooftop solar. The renewable portfolio is adequate but not a company differentiator.
Market presence (4.0/5)
IGS is one of the larger regional energy companies in the Midwest and Mid-Atlantic. Operating since 1989, the company has staying power. The multi-state footprint can be valuable for customers who move between IGS service areas.
As a privately held company, IGS lacks the financial transparency of publicly-traded competitors — but has demonstrated durability over three decades.

Frequently asked questions
Is IGS Energy a legitimate company?
Yes. IGS Energy (Interstate Gas Supply, Inc.) is a privately-held energy company founded in 1989 and headquartered in Dublin, Ohio. The company holds active licenses from public utility commissions in multiple states including Pennsylvania, Ohio, Indiana, Michigan, and Kentucky. IGS serves both residential and commercial customers and is one of the larger regional energy suppliers in the Midwest and Mid-Atlantic.
What is the difference between IGS Energy and IGS Solar?
IGS Energy supplies electricity and natural gas to residential and commercial customers through competitive retail energy markets. IGS Solar is a related division that sells and installs residential solar panel systems. The two operations are connected but serve different purposes. Most online complaints about IGS relate to the solar division's door-to-door sales practices, not the electricity supply business. If you're considering IGS for electricity supply only, the solar complaints are less relevant to your experience.
Why do some IGS reviews mention door-to-door sales?
Most door-to-door complaints involve IGS Solar, the company's solar panel installation division, rather than IGS Energy's electricity supply business. Solar installations are high-ticket purchases that salespeople actively pursue through door-to-door canvassing. If you were approached at your door about solar panels, that's IGS Solar. If you're researching IGS Energy for electricity supply, you would typically enroll online or by phone, not through door-to-door solicitation.
Does IGS Energy operate in Pennsylvania?
Yes. IGS Energy holds an active electricity supplier license from the Pennsylvania Public Utility Commission. The company offers residential electricity plans in Pennsylvania's deregulated utility territories. IGS also serves Pennsylvania customers with natural gas in applicable service areas.
How does IGS Energy compare to other PA suppliers?
IGS Energy typically positions in the mid-range of Pennsylvania electricity rates — not the cheapest option, but not expensive either. The company offers a standard mix of fixed and variable rate plans. For customers who prioritize lowest rates above all else, suppliers like Public Power often beat IGS on price. For customers who value a multi-state regional supplier with both electricity and natural gas options, IGS may be a reasonable fit.
