The heart of the matter


The hydraulic Fishheart fishway is a Finnish innovation enabling fish to migrate past obstacles. European energy company Fortum has recently installed the system at one of its hydropower plants


THE 25MW LEPPIKOSKI HYDROPOWER plant was completed in 1963. It is located along the Emäjoki River, in the Oulujoki river shed in Finland. The scheme has two Kaplan turbines, two embankment dams (40m and 450m long) and a 57m long concrete dam. The


concrete dam comprises a spillway with two gated openings, and a bottom outlet spillway located below a decommissioned log floating basin. The Finnish National Fishway Strategy prioritises sites according to their potential for restoring river
