Vectren Electric Infrastructure Plan

The OUCC, industrial customers who have intervened, and Vectren have reached a settlement agreement in the utility's electric infrastructure case. The agreement is pending before the IURC, which may accept, modify, or deny it:

All hearings in this case have concluded. Written closing arguments have been filed, including the settling parties' proposed order.

The IURC case file is available by clicking here and entering Cause Number 44910.

For more background information on the case, please see the OUCC's fact sheet, distributed at the IURC's May 2, 2017 public field hearing in Evansville.

Vectren has filed its request under a law (Senate Enrolled Act 560) passed by the Indiana General Assembly in 2013.

The pending proposal would only affect Vectren's electric utility in southwestern Indiana. Infrastructure plans for Vectren's Indiana natural gas utilities were approved in 2014.

On August 1, 2017, Vectren filed its first electric TDSIC tracker request. In its filing (44910 TDSIC 1), the utility states that it is waiving its right to a 90-day schedule and proposing that the OUCC's testimony be due four weeks after an order is issued on the seven-year plan. The utility's requested tracker would raise a monthly residential bill for 1,000 kWh by 57 cents.

A brief summary of the 2013 law

Indiana Code 8-1-39 allows electric and natural gas utilities to submit 7-year infrastructure improvement plans for IURC approval. It requires the IURC to rule within 210 days once such a request is filed.

  • Once a 7-year plan receives IURC approval, the utility may request incremental rate increases every 6 months to pay for the projects. The rate adjustment is referred to as the Transmission, Distribution and Storage System Improvement Charge (TDSIC). The IURC has 90 days to rule on such a request.
  • TDSIC rate increases are limited to no more than 2 percent of a utility's total retail revenues.
  • The TDSIC rate mechanism (or tracker) allows the utility to recover 80 percent of the costs as they are incurred. The remaining costs are deferred until the utility's next base rate case, which must be filed before the end of the 7-year period.
