Duke Energy has received authorization to install new pollution control equipment at its Cayuga, Gallagher and Gibson generating stations, 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 39-page order in this case on April 3, 2013.
In filings with the IURC, Duke Energy stated that the U.S. Environmental Protection Agency's (EPA's) Utility Mercury and Air Toxics Standard (MATS) rule was the primary reason for its request. The Indiana Office of Utility Consumer Counselor (OUCC) filed testimony with the IURC on November 29, 2012, recommending reductions to the costs Duke Energy was seeking to recover. The Commission's order reduced the allowed cost recovery by more than $50 million from the utility's original request.
