Indiana Natural Gas Corp. Rates

Indiana Natural Gas Corporation provides service in 7 southern Indiana counties: Bartholomew, Brown, Crawford, Dubois, Lawrence, Harrison, and Orange.

To compare average natural gas bills, see the IURC's monthly residential surveys. Key components of a natural gas bill include gas costs and base rates.

Gas Costs

Natural gas utilities buy gas for their customers in a competitive wholesale market. Indiana law allows utilities to adjust rates every three months to recover changes in those costs, which can go up or down. These costs comprise a significant portion of a residential bill and are recovered through the Gas Cost Adjustment (GCA) process.

  • Utilities may recover wholesale gas costs on a dollar-for-dollar basis but may not profit on them.
  • Before adjusting rates to reflect the costs, a utility must demonstrate that it has shopped prudently in the competitive market.
  • Each GCA filing requires OUCC review and IURC approval.

The utility's most recently approved request (Cause No. 37418 GCA-153) will affect bills for May, June, and July.

Base Rates

Base rates cover a utility's operational, maintenance, and capital costs. Investor-owned utilities are allowed to earn a return on base rates.

The IURC approved Indiana Natural Gas Corporation's base rates in 2014.
