To compare natural gas bills for regulated Indiana utilities, see the IURC's monthly residential surveys.
Key components in natural gas bills include gas costs and base rates.
2024 Base Rate Case
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.
New rates and charges for South Eastern Indiana Natural Gas Co. received IURC approval on Dec. 11, 2024. The Commission's order approved a settlement agreement between the OUCC and the utility.
All publicly filed documents in the rate case (Cause No. 46074-U) are available on the Commission's website.
The OUCC issued a July 10, 2024 news release to invite public comments.
The utility requested the increase through the state's Small Utility Filing Procedure, which is aimed at reducing rate case expenses while not reducing the standard of review by the OUCC and IURC.
The IURC approved the utility's previous base rates in 2018.
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.
South Eastern Indiana’s GCA rate adjustments are approved every three months under IURC Cause Number 37785. Orders approving rate adjustments include specific bill impacts and are available from the electronic files on the IURC website.
