Understanding Your Bill

Delivery Charges

Delivery charges are Nicor's costs to operate and distribute gas to you. These charges make up about 15 to 20 percent of your gas bill over one year. 

Monthly Customer Charge
This is a minimum charge for most customers and it is the same each month - even if you do not use natural gas that month. For Rate 4 business customers, this charge is based on your meter size and your potential maximum hourly use of natural gas in cubic feet per hour (cfh). Most business customers are in the "less than 1,000 cfh" category. 
 
 
  • Less than 1,000 cfh:  $20.37
  • 1,000 cfh to 10,000 cfh:  $59.82
  • More than 10,000:  $105.56
Therm Usage/Distribution Charges
These charges cover our fixed and variable operating and distribution costs. A portion of these charges varies from month to month based on the amount of natural gas you use. There are price variations at certain levels of therm usage.
 
Volumetric Delivery Charges
