MADISON, Wis., July 2, 2014 /PRNewswire/ -- Additional air quality improvements are planned for one of Wisconsin's largest power plants. Today Alliant Energy's Wisconsin utility, Madison Gas & Electric Co. and Wisconsin Public Service Corp. jointly filed a request with the Public Service Commission of Wisconsin (PSCW) to install air quality improvement technology at Columbia Energy Center near Portage, Wis.

"This project will improve the environment, create jobs and support Wisconsin businesses," said John Larsen, President of Alliant Energy's Wisconsin utility. "This air quality control system will help us provide customers with cleaner, reliable and efficient electricity for decades to come."

The equipment responsible for cleaning the air is a selective catalytic reduction system (SCR) at Columbia Unit 2 that will reduce nitrogen oxide (NOx) emissions by approximately 50 percent. The estimated project cost is $150 million.

The SCR project is expected to begin construction in 2016 with an anticipated completion in 2018. The project will provide hundreds of jobs during peak construction.

Alliant Energy and its co-owner utility partners are completing their first major environmental investment at the plant. This year, baghouse and scrubber systems will be put into operation at Columbia Units 1 and 2, which will reduce sulfur dioxide (SO2) and mercury emissions by approximately 90 percent on each unit.

These projects are part of Alliant Energy's plan to invest in air quality control systems at its newer, larger and most efficient generating units.
