Indianapolis Power & Light Company (IPL) has received approval to install new pollution control equipment at its Petersburg generating station and Unit 7 of its Harding Street station, primarily to reduce mercury emissions. The utility also received approval to recover the construction costs through rates, with rate adjustments to be requested every six months.
The Indiana Utility Regulatory Commission (IURC) issued its order in this case (51 pages) on August 14, 2013.
In filings, IPL stated that it requested the plan to comply with the U.S. Environmental Protection Agency's (EPA's) Utility Mercury and Air Toxics Standard (MATS) rule. IPL estimates the compliance plan's capital costs at nearly $511 million, not including financing and demolition costs.
An IURC public field hearing was held on Thursday, January 24, 2013, with the OUCC issuing a January 11, 2013 news release to invite comments. The fact sheet the Indiana Office of Utility Consumer Counselor (OUCC) distributed at the field hearing offers more information.
