Kallioinen
There are two hydroelectric power plants on The Sotkamo Route. The lower one, called Kallioinen, is located in Sotkamo. The power plant was designed by Eino Pitkänen and Jaakko Asikainen. Kallioinen was commissioned in 1957.
History
Kallioinen is located on the Ontojoki in the municipality of Sotkamo. It is the lower of the two hydroelectric power plants in the so-called “Route of Sotkamo” that flows from the eastern border of Finland. The design process was started by Eino Pitkänen. After he passed, Engineer Jaakko Asikainen continued his work staying true to Eino Pitkänen´s vision.[1]
Kallioinen was refurbished in 2001 and is now owned by UPM Energy. The power plant has one Finnish Kaplan turbine and it produces 13.5 MW of power. Notable features of Kallioinen include special equipment that can be used for hoisting logs over the power plant.[2]
