Harsprånget is a hydroelectric power station located on the Lule River in northern Sweden, just downstream of Porjus.
With an effect at 977 MW, it's the largest hydroelectric power station in Sweden, and also the third largest in the nordic countries. The name means "Hare run" in Swedish. This was also the name of the mighty rapids there, and the name was related to the sharp turns in the rapids, a little similar to the ones a hare does when fleeing. Normal year production is around 2131 GWh. Total fall height is around 107 m.
Construction of the station started in 1918. However, recession after World War I cancelled the construction, which was not started again before 1945. It was opened in 1951, then with an effect of 330 MW. In 1980, two new turbines were installed which increased the max effect to 945 MW. The effect was later increased further.
