Community Natural Gas Co. provides service in 10 southern Indiana counties.
To compare average residential billing amounts for regulated natural gas utilities, see the IURC's monthly residential surveys.
Key components in natural gas bills 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.
Community Natural Gas Co. and the OUCC reached a settlement agreement in the utility's most recent rate case (Cause No. 46209), which received Commission approval in September 2025. All publicly filed documents in the case, including testimony supporting the settlement, are available on the IURC website.
Previous base rates for Community Natural Gas Co. were approved in October 2022.
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.
Community’s GCA rate adjustments are approved every three months under IURC Cause Number 37488. Orders approving rate adjustments include specific bill impacts and are available from the electronic files on the IURC website.
