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-163) has received approval and will affect bills for November 2024, December 2024, and January 2025.
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.
