Nitrogen Oxide Retrofit Projects
Weston Units 1 + 2
Environmental Retrofits at WPS
A series of emission control projects have been completed at the WPS coal-fueled power plants allowing WPS to meet stricter state and federal air quality regulatory requirements.
Project Description
The new equipment was installed to better control the combustion process and thereby reduce Nitrogen Oxide (NOx) emissions by 40 to 50 percent overall. NOx contributes to acid rain, ozone and fine particulate emissions. NOx emissions and their downwind impacts are regulated under multiple State and Federal air quality regulatory programs.

Project Timeline
- Fall 2008 - Weston 1 (Completed)
- Spring 2009 - Weston 2, Pulliam 6 and Pulliam 7 (Completed)
- Fall 2009 - Weston 3 and Pulliam 8 (Completed)
- Spring 2010 - Pulliam 5 (Completed)
Equipment Installation
To better control the combustion process and reduce NOx emissions, WPS installed low NOx burners and "Separated Over-Fire Air" or SOFA. The equipment was installed during regular scheduled maintenance outages at each of the seven units. The Public Service Commission of Wisconsin (PSCW) and the Wisconsin Department of Natural Resources (WDNR) approved the construction of the NOx reduction projects.

Columbia Energy Center Sulfur Dioxide Emission Reduction Project
- Spring 2011 - WPS owns 31% of the Columbia Energy Center which has approval to install a dry flue gas desulfurization system reducing the plant's sulfur dioxide (SO2) emissions. The project is scheduled to be operational in 2014. The Columbia Plant is located near Portage, Wisconsin and WPS shares ownership with Wisconsin Power and Light and Madison Gas and Electric.
