Parteboda is the smaller of the two plants using the Ångesjön Lake as its reservoir. The Ljunga power plant was built in 1971–1973. It is a combination of a cliff station and a land station. The water that passes through the turbines is lead through a 6 km long drain pipe that empties into the Torpsjön Lake.​
