Vectren Energy Delivery is requesting approval to install new pollution control equipment at its electric generating stations to reduce mercury and sulfur trioxide emissions.

In filings with the Indiana Utility Regulatory Commission (IURC), Vectren states that it is seeking the plan to comply with several U.S. Environmental Protection Agency (EPA) rules, including the Utility Mercury and Air Toxics Standard (MATS) rule. Vectren estimates the compliance plan's capital costs at between $70 and $90 million. While the utility is not seeking rate recovery of these costs in its current case, it is allowed to request recovery at a future time under Indiana law.

Vectren filed its petition (17 pages) initiating this case on January 17, 2014. For all publicly filed documents in this case, including Vectren's testimony and exhibits, please visit the IURC's electronic document system and enter docket number 44446.

The Indiana Office of Utility Consumer Counselor (OUCC) filed amended testimony (9 pages) on July 17, 2014, in addition to its May 28, 2014 case-in-chief:

  • OUCC Testimony: Armstrong (65 pages)
  • OUCC Testimony: Rutter (99 pages)
