The 7, 2 MW Qorlortorsuaq hydropower project is located in south western Greenland. The project harneses the outflow of water from a natural lake in the area by constructing a headrace tunnel into the bottom of the lake and raising the lake level by 7 m by a small dam. The headrace tunnel runs 220 m through a hill and is connected to a 280 m long steel penstock, feeding two horizontal axis Francis turbines, in a conventional powerhouse.
A short tailrace canal directs the turbine water to the sea. The harnessed head is approximately 125 m. The power is fed to the towns of Narsaq and Qaqortoq by approximately 70 km of 66kV transmission lines.
