This project studies the hydrological situation regarding small hydropower plants Kolsi and Harjavalta, situated on the river Kokemäjenjoki, in order to propose improvements for more optimal use of generation potential. It draws out the best practice from a long-term experience of project implementations in Finland. Additionally, the variant with adding one more generating unit to the Harjavalta plant was studied in details.
