Illinois Energy Solutions is not the same entity as your gas delivery company. You are not required to enroll with Illinois Energy Solutions. Beginning on 10/1/2026, the Nicor Gas' gas supply cost rate is $0.33 per therm. The utility gas supply cost will expire on 10/31/2026. For more information go to the Illinois Commerce Commission's free website at www.icc.illinois.gov/ags/consumereducation.aspx.

Enrollment eligibility is subject to Illinois Energy Solutions' credit and payment policies, and other eligibility requirements. The total Fixed Bill plan charges over the term of the plan agreement may be higher than the total cost of traditional utility service over that same period and customers may not save money on the plan. Call us at 1.888.636.1789.
