Construction continues to move along at the Columbia Energy Center, near Portage, Wisconsin, where Wisconsin Power and Light Company (WPL) is installing baghouse/carbon injection and scrubber systems on Units 1 and 2.
The baghouse/carbon injection and scrubber system will reduce mercury (Hg) emissions for compliance with Wisconsin’s mercury rule and sulfur dioxide (SO2) emissions to comply with state and federal SO2 reductions. They will also provide the additional benefits of capturing fine particulate matter and reducing sulfuric acid mist.
Construction on this approximately $630 million project began in early spring of 2012. WPL continues to anticipate commercial operation of the controls in 2014.
