Dairyland Implements Major Emission Control Equipment
Dairyland Power Cooperative has installed a fabric filter “baghouse” to enhance particulate matter (very light ash) capture at its 400 MW John P. Madgett (JPM) coal-fired power plant in Alma, Wis. The new emissions control equipment was brought into service in late October at the JPM plant.
Dairyland also installed a baghouse at its 380 MW Genoa Station #3 (G-3) coal-fired power plant in Genoa, Wis, several months ago. Results have shown a major reduction in particulate matter at the Genoa power plant site.
Baghouse technology removes particulate matter from the exhaust gas stream following the coal combustion process. This technology is in addition to existing electrostatic precipitator particulatematter control equipment at each plant.
ADDITIONAL TECHNOLOGIES WILL HELP REMOVE SULFUR DIOXIDE, MERCURY, NITROGEN OXIDE
Dairyland has budgeted in excess of $250 million to retrofit G-3 and JPM, its two largest power
plants, with state-of-the-art environmental control equipment that will result in significant air
emission reductions. The baghouse equipment to capture particulates is in place. Future planned
environmental control projects include:
• The installation of a dry flue gas desulfurization system, or “scrubber,” to remove sulfur
dioxide. Preliminary estimates indicate upwards of 90 percent of sulfur dioxide could be
captured by the scrubber.
• Enhanced mercury removal, and new burners to modify the combustion process to reduce
nitrogen oxide emissions.
These technologies are scheduled to become operational over the next few years. When operational, the new air emission control equipment will achieve significant reductions of sulfur dioxide, nitrogen oxide, mercury and particulate matter.
With headquarters in La Crosse, Wis., Dairyland provides wholesale electricity to 25 member
distribution cooperatives and 19 municipal utilities. A Touchstone Energy Cooperative, Dairyland’s
service area encompasses 62 counties in four states (Wisconsin, Minnesota, Iowa and Illinois).
Dairyland’s generation resources include coal, natural gas, hydro, wind, landfill gas and animal
waste. For more information on the cooperative, please visit www.dairynet.com.
