Midwest Natural Gas Corporation provides service in 10 southern Indiana counties.

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.

Pending Rate Case

Midwest Natural Gas Corporation is requesting a rate increase in a newly filed case.

All publicly filed documents in this case (Cause No. 45888) are available on the IURC's website.

Update (10-3-23): The OUCC and utility have reached a settlement agreement.  The OUCC filed supporting testimony on Sept. 29, 2023.

The utility filed its petition and the following testimony on May 17, 2023:

The OUCC issued a June 21, 2023 news release to invite written comments through Aug. 16. 2023.

Most rate cases take approximately 300 days to complete, and a final order from the IURC is not expected until Winter 2024. The OUCC's timeline outlines the steps in the process.

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.

  • 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.

Midwest Natural Gas Corporation files gas cost adjustment requests every three months.

Its most recent GCA (Cause No. 37440 GCA-159) has received approval and will affect bills for November 2023, December 2023, and January 2024.

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.

Midwest Natural Gas Corporation's current base rates received Commission approval in 2017.

Infrastructure Improvement Plan

Midwest Natural Gas Corp. has received approval of a long-term infrastructure plan with periodic rate increases as allowed by state law.
