It gets its water from Nedre Navervatn lake which is located about 465 metres (1,526 ft) above sea level.

The plant also house a newer 2.4-megawatt (3,200 hp) Francis generator taking water from Fykanvatn lake as well.

During the Second World War the Germans started expanding with three additional turbines, but in 1942 an Anglo-Norwegian raid, Operation Musketoon, attacked the German-held power plant.

At this time it reached its peak of 120 megawatts (160,000 hp) from 6 equal Pelton turbines, which lasted until Svartisen power plant was completed in 1993.

Generators 4-6 were removed around 2012 to make room for a 2.4-megawatt (3,200 hp) Francis turbine using water from Fykanvann that opened in 2013.
