The main objective of the project is to explore the possibilities of developing technologies for small-scale hydropower plants in the North Calotte area that would be environment-friendly, in line with the existing legislation and that would not impede natural fish migration. The technology will first and foremost be used for renovation of the existing hydropower plants to bring them in line with the existing ecological requirements, as well as for rebuilding of spillways in the existing dams that are lacking fish tunnels and do not produce energy
