Environmental Equipment InvestmentsMajor projects at Dairyland’s two largest power plants are benefitting regional air quality
Major environmental equipment installations at Dairyland’s coal-fired power plants include the "baghouse" pictured in the foreground of this photograph of the JPM plant site. Baghouses at the Genoa and JPM plants remove particulate matter. Dairyland is in the process of retrofitting its Genoa #3 (G-3) and John P. Madgett (JPM) power plants with state-of-the-art environmental control equipment to achieve significant air emission reductions. The G-3 coal-fired plant is located in Genoa, Wis. The JPM coal-fired plant is located in Alma, Wis. As part of its environmental commitment, Dairyland is in the midst of an ongoing $400 million air emission control plan at its coal-fired generating facilities in Alma and Genoa. When this plan is complete, Dairyland’s sulfur dioxide emissions will be reduced by over 90 percent. This will be in addition to the 80 percent reduction of sulfur dioxide emissions by Dairyland since the early 1970s. Nitrogen oxides emissions will be reduced by over 50 percent across the Dairyland system. Through this broad-reaching plan, Dairyland has already made major reductions in emissions of sulfur dioxide, nitrogen oxides and particulate matter by investing in new air emission control equipment. For example, Dairyland has installed fabric filter “baghouses,” designed to remove more than 99.5 percent of particulate matter from the exhaust gas stream, at both the Genoa facility and the John P. Madgett (JPM) facility in Alma. Dairyland also installed a semi-dry flue gas desulfurization system, or “scrubber,” to remove sulfur dioxide at its G-3 plant in Genoa in early 2010, and sulfur dioxide controls are planned for the JPM plant in Alma. Equipment to reduce emissions of nitrogen oxides (NOx) at G-3, JPM and the Alma Station units 4 and 5 has also been implemented. Click here for background information on the JPM power plant.
