To compare average residential gas bills, see the IURC's monthly residential surveys.
Key components in a Citizens 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.
Citizens’ GCA rate adjustments are approved every three months under IURC Cause Number 37399. Orders approving rate adjustments include specific bill impacts and are available from the electronic files on the IURC website.
