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

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.
