These past few winters we've endured all sorts of surprises, including Polar Vortexes and massive snowstorms. If there's a lesson to be learned, it's that you never know what winter will bring. Enroll in Illinois Energy's Guaranteed BillSM plan and no matter how cold it gets or how much gas prices change, you'll have the same monthly payment for 12 months.
And as a special bonus for enrolling online in our Guaranteed Bill plan, we'd like to offer you a $25 Visa® Reward Card!*
Please note: Our name changed from Nicor Advanced Energy LLC to Illinois Energy, USA, LLC on November 1, 2017.
