The small-scale Louhikoski hydropower plant with pipes is quite rare in the Finnish conditions. The upper channel conducts the water into a long entry pipe that takes the water into three turbines.

The State participates in the project to demolish the Louhikoski hydropower plant in the River Saramojoki in Nurmes and to free the river. This was made possible by the decision of Pohjois-Karjalan Sähkö to demolish the plant free of charge and the fact that the demolition will not lead to any obligations related to the dam, regulation or other matters.

The River Saramojoki is one of the most significant watercourses that discharge into Lake Pielinen. Because there are no other major structures that prevent the passage of fish in the river, the demolition of the plant opens an extensive river basin for migratory fish.

In particular, the project will enable the River Vuoksi lake trout that has been classified as threatened to breed in the wild and build a stronger population in Lake Pielinen. Besides the interests of fisheries, this multiple-use project serves the objectives to promote tourism and the need to reorganise the hydropower economy. The water permit application for the project will be submitted to the Regional State Administrative Agency within the next few weeks.

The project to demolish the Louhikoski hydropower plant was launched on the initiative of the electricity company Pohjois-Karjalan Sähkö as the company was looking for alternatives to the renovation of the plant. The total costs of the demolition will be about EUR 1.7 million. The State will contribute about 25% of the total costs of the project. Besides the migratory fish programme NOUSU, the project to demolish the Louhikoski hydropower plant and free the river will be funded by several public organisations and private donors.

-This is the first demolition project concerning a small-scale hydropower plant that receives funding from the migratory fish programme NOUSU. Setting the River Saramojoki free provides the opportunity to develop the fisheries, recreational use and nature tourism of this river basin in quite a unique manner. The project serves as a good example of a joint effort for the benefit of watercourses and migratory fish, says Jari Leppä, Minister of Agriculture and Forestry.
On 11 September 2020 Minister Leppä met key stakeholders in Nurmes and the Lake Pielinen area, visited the Louhikoski hydropower plant and examined the demolition plans.

-The implementation of this quite unique project that will enhance the value of Lake Pielinen and the River Saramojoki river basin was made possible by the strong commitment of the State and broad cooperation between the municipalities and other stakeholders in the area, says Asko Saatsi, Chief Executive of Nurmes.

By means of support and measures under the migratory fish programme NOUSU Prime Minister Sanna Marin’s Government aims to improve the status of migratory fish and threatened fish populations in different parts of Finland. The programme continues the work started as a key project by Prime Minister Juha Sipilä’s Government.
