- Quarterly Gas Cost Adjustments
Natural gas utilities buy gas for their customers in a competitive wholesale market. Indiana law allows utilities to adjust rates every three months 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.
The utility's most recent adjustment (Cause No. 37394 GCA-158) was approved in May 2023 and will affect bills for June, July, and August.
- Infrastructure Plans
State law allows natural gas and electric utilities to seek IURC approval of 5-to-7-year plans for infrastructure improvements. If a plan is approved, the utility may then seek incremental rate increases as the projects proceed. Most costs are recovered through the Transmission, Distribution, and Storage System Improvement Charge (TDSIC). Vectren North's first gas TDSIC plan received Commission approval in 2014. It received Commission approval of a new five-year plan in Cause No. 45611 in April 2022.
