Has three anaerobic digesters (0.8 MWs). Also, the Chariton Valley Biomass Project (a cooperative effort with Chariton Valley Resource Conservation and Development, and the U.S. Dept. of Energy) is an initiative to develop switchgrass and other grasses Operates two biomass-fueled facilities: Rapids Energy Center at Grand Rapids and Hibbard Energy Center in Duluth that mainly consume production waste from adjacent paper mills and purchased wood. Both units also burn coal. Xcel Energy has contracted for the development of 110 megawatts of electricity generated by biomass-fueled technologies. Waste wood, fastgrowth poplar trees, and poultry litter will all be used as fuel to generate electricity.
