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.
Midwest Natural Gas Corp.’s GCA rate adjustments are approved every three months under IURC Cause Number 37440. Orders approving rate adjustments include specific bill impacts and are available from the electronic files on the IURC website.
