Nicor Gas "Price to Compare"

If you don’t sign up with an energy supplier of your choice, Nicor Gas will continue to provide you “default” energy service at a rate approved by your state’s public utility commission. If possible, you should avoid the “default” energy service, since you will likely pay a higher rate than you would with an independent energy supplier.

This rate is your “Price to Compare.” The Price to Compare can help you figure out how much you’ll save by switching from the utility’s plan to one offered by an independent energy supplier. If the supplier’s rates beat the utility‘s “Price to Compare,” you can save the difference per therm by switching to that supplier. Nicor Gas customers can easily shop for natural gas plans to see if there’s one better than the default rate.
