The John P. Madgett Station (JPM) is south of the former Alma Station site, along the Mississippi River in Alma, Wis. JPM was built in the late 1970s at a cost of $179 million.
Named after the late John P. Madgett, general manager of Dairyland Power Cooperative from 1947 to 1978, JPM has been in commercial operation since November 1979. The single-unit station has a generating capacity of 387 MW of electricity.
