Base Rates

CenterPoint Energy Indiana North's pending rate case is IURC Cause No. 45468. The utility initially proposed an annual increase of $20.8 million, modifying the request to $19.9 million in rebuttal testimony.

A settlement agreement among all of the case's parties would reduce rates by $5.9 million if approved. The OUCC and CenterPoint Energy have filed testimony supporting the agreement which is now pending. The IURC may approve, deny, or modify any settlement agreement it considers.

The case's evidentiary hearing is continued until Aug. 6, 2021.

The OUCC recommended denial of Vectren's request in the following testimony, as described in our April 1, 2021 news release:

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. 39374 GCA-150) was approved in May 2021. The OUCC filed testimony in April.

Seven-Year Infrastructure Plan

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 current gas TDSIC plan received Commission approval in 2014.
