Rates and Costs
We want you to be informed about your rate options.
Nicor Gas has its Rates and Riders on file with the Illinois Commerce Commission (I.C.C.) and they are also listed in our Schedule of Rates for Gas Service (I.C.C. No. 16) – also called our Rate Book.
A number of Riders on file with the I.C.C. are updated monthly, including Rider 6 – the Gas Supply Cost (GSC). Updates to information sheets are posted on the first of each month.
