Reducing Pollutants 
Our pollution reduction standards are earning praise and getting results. 
 
Ameren: A Recognized Leader In Clean Energy
Ameren's merchant generating energy centers have established a compliance strategy that targets many types of emissions. Our strategy includes: 
   
  • Installing sulfur dioxide (SO2) scrubbers at the Coffeen and Sioux Energy Centers. 
     
  • Using low-sulfur coal. 
     
  • Purchasing SO2 allowances. 
     
  • Using a combination of low NOx burners, selective catalytic reduction and intelligent combustion controls to increase operational efficiency and reduce NOx emissions by 85% from the generating fleet. 
     
  • Installing an upgraded scrubber at our Duck Creek Energy Center to significantly remove sulfur dioxide. 
     
  • Installing mercury reduction technology on 14 generating units. 
     
  • Installing upgraded particulate controls at Coffeen, Duck Creek and Labadie Energy Centers.
