In December 2011, Dairyland Power Cooperative said it will stop using three aging coal-burning units at the Alma Station, adding up to about 60 megawatts. The three units, all built in the 1950s, generated just 0.4 percent of the cooperative’s power in 2011 and would now only be used for emergencies. Two other Alma coal plant units with 120 megawatts of capacity would continue supplying the network.[1]

Units 1-3 were retired in 2012, and units 4-5 retired in 2014.[2]
