The 15 MW Sisimiut hydropower project in western Greenland, north of the town Sisimiut, involves harnessing of the outflow of a natural lake by constructing a headrace tunnel into the bottom of the lake and thus creating a reservoir. The headrace tunnel is 4.1 km long and will feed a 420 m long pressure tunnel to an underground powerhouse, housing two Francis units, each being 7.5 MW.
The harnessed head is 79m and the design flow is 22m3/s. Power is transferred from a GIS substation, using a 26km long 66kV transmission line, to the town of Sisimiut.
Services included:
- Assistance during commissioning
- Recommendations in regard to the improvement of operation systems
- Setting up maintenance and operation programs
- Training operators and technical management of operations during the one year guarantee period
