IPL Environmental Controls Construction Project

Indianapolis Power and Light Company (IPL) provides electric service to more than 470,000 users in the area and surrounding communities, with Petersburg and Harding Street Plants, the company’s two biggest plants, accounting for a majority of that generation. In order to meet EPA Mercury and Air Toxics Standards (MATS) compliance, IPL is retrofitting five units at these sites with new environmental control equipment. 

The team of Kiewit and Sargent & Lundy LLC was selected to  engineer, procure and construct the pulse jet fabric filters, SBS, ACI, ESP upgrades and associated BOP equipment. Equipment includes Siemens PJFFs and Howden fans. 

These upgrades will keep the existing coal-generation fleet in compliance with EPA regulations while keeping the cost of power low to rate payers. Once complete, the upgrade is estimated to reduce mercury emissions by 80 percent. The work is expected to take about three years and add 300-400 jobs during the peak of construction.
