Key components in a gas bill include base rates and gas costs.
Base Rates
Base rates cover "non-gas" costs for a utility, including operational, maintenance, and capital costs. A natural gas utility is allowed to earn a return on this portion of the bill.

All publicly filed documents in the rate case are available on the IURC Portal case page for Cause No. 46086.
Indiana Utilities Corporation's previous base rates were set in February 2019.
Gas Costs
Natural gas utilities buy gas for their customers in a competitive wholesale market. Indiana law allows utilities to adjust rates periodically 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.
Indiana Utilities Corp.'s GCA rate adjustments are approved every six months under IURC Cause Number 37357. Orders approving rate adjustments include specific bill impacts and are available from the electronic files on the IURC website.
