History

The power plant was built in 1920 to a design by the architect

Olaf Nordhagen Johan Olaf Brochmann Nordhagen (16 March 1883 – 6 November 1925) was a Norwegian educator, architect, engineer and artist. He is most commonly associated with his restoration designs for Nidaros Cathedral in Trondheim, Norway. Biography Olaf ...

. It opened with two Pelton turbines at 20 MW each delivering power at 25 Hz. In 1922 a third one was opened. At the time these were the largest turbines in operation in Norway.
During the

Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposi ...

, attacked the German-held power plant. The plant slowly got back into operation, but the tree generators were never completed by the end of the war. They were completed between 1948 and 1949. At this time it reached its peak of 120MW from 6 equal Pelton turbines, which lasted until Svartisen power plant was completed in 1993.
Because Svartisen used most of the water, Glomfjord was scaled back and only generator 3 was being used. It was also converted to 50Hz operation and connected to the main power grid.
Today only generators 1-3 remains with 3# in normal operation. 4-6 were removed around 2012 to make room for a 2.4MW Francis turbine using water from Fykanvann that opened in 2013.
