Natural Gas



Proudly Serving the Prairie State

Here in Illinois, we’re proud to offer a wide range of products and services to homeowners like you. These include electricity, natural gas, solar, and home warranty products available at a variety of term lengths and protection levels. We even offer products that can make your home smarter and some that can help the planet. The state became deregulated for natural gas in 1997 and electricity in 2002, and we began supplying the area beginning in 2003 and 2011, respectively. 

Connected to the Community

We’ve been an advocate for the consumer since day one, and in every community where we live and work. Additionally, we’re committed to investing our time and dollars to support schools and nonprofits throughout the state. We’re also passionate about creating strong relationships by supporting area teams like the Chicago Bears (we supply electricity to Halas Hall) and organizations that share our dedication to building strong communities, like the Chicagoland Speedway & Route 66 Raceway (as their natural gas and electricity supplier).
