Kangaskoski

Kangaskoski is located near the state border

Kangaskoski is the lowest rapid on the Finnish side of the Hiitolanjoki River, located about a kilometer from the Russian border. The height difference of Kangaskoski is about 4 meters. The average annual electricity generation is 3300 MWh.

The industrial history of Kangaskoski dates back over a hundred years. At the beginning of the 20th century, when the export business at the abrasive and paper mills became more complex, Aktiebolaget Simpele, the predecessor of the United Paper Mill, bought Kangaskoski and the border Syrjäkoski for electricity production. The Kangaskoski hydroelectric station, designed by Hugo Eklund and built by Suomen Rakennus Oy, was put into operation in 1925.

Kangaskoski Dam will be demolished in 2021

Kangaskoski Power Station is owned by Hiitolanjoen Voima Oy, which was transferred to the South Karelian Recreation Area Foundation in October 2019.

Today, the almost dry riverbed on the opposite bank has been a bypass channel since the beginning of the 20th century. After two years, the waters will again begin to fill the original river bed, forming natural rapids, where salmon can rise upstream.

Kaplan turbine – as a museum attraction

Kangaskoski still uses, for the most part, the original technological components of the power plant. Technological components include: the first Kaplan turbine (Tampella 1924), made in Finland, and a control unit from the time of construction. In Kangaskoski, it is planned to open the Museum of the power plant after the production of electricity is stopped in 2021.

Today, passing on the opposite bank, almost dry, the riverbed has been a bypass channel since the beginning of the 20th century. When it again becomes full-flowing, the rapids will again begin to attract valuable species of fish in their stream.
