Harjavalta Hydropower Plant
New 21 MW unit for the Harjavalta hydro power plant in Finland

Description of project:
The Harjavalta power plant in Southwestern Finland consists of two units with a combined nominal flow of 360 m3/s, 26.5 m head, output of 73 MW and average annual production of 390 GWh. During the project, a new additional unit will be built parallel to the old units. The new unit increases the efficiency during small flows and decreases the need for capacity spills. Output of the unit is 21 MW and annual production is 30 GWh.
