Grandiose hydroelectric power station in Iceland for which it was necessary to drill 70 kilometers of tunnels

The reason for the construction of the Kaurahnjukar hydroelectric power station with a capacity of 690 MW was the government's plans to develop the economy of Iceland. It was decided to invest in expanding energy-intensive industries, and for this it was necessary to more fully use the country's hydropower potential. So the plan for the construction of the Kaurahnyukar hydroelectric power station came about, which would provide an electric power plant to the nearby aluminum plant.

The new hydroelectric station, the construction of which was completed in 2009, has a very complex structure and includes a whole range of structures. These are 5 dams, 3 reservoirs, an underground hydroelectric building and a tunnel system. In order for the hydropower plant to work successfully, the builders had to channel the waters of two rivers fed from the glacier through an underground tunnel, and the total length of the underground structures was 73 kilometers. The video below shows how an unusual hydropower plant in Iceland works.
