You have the power to choose in Illinois

In 1997, Illinois passed legislation that gave consumers the power to shop for competitive natural gas rates. Instead of requiring consumers to pay Nicor Gas supply rates, people in the area can compare supply rates and search for a different offer.

Should you find a good deal, you’re free to switch away from Nicor Gas supply without penalty. As per the energy choice law, the utility is required to deliver energy to your home, regardless of which supplier you choose. If you decide Nicor Gas supply rates aren’t right for you, the utility will still provide the same great service.
