The power plant is located 11 kilometres above the mouth of the Rana River at Mo i Rana and uses the height of fall of 25.6 metres in the Reinforsen rapids.
The power plant has two generating units equipped with Francis turbines. The power plant has a long history starting from when it was commissioned in 1925. Dunderland Iron Ore Company was responsible for the development and operation of Reinforsen until 1950.
The turbines have a maximum discharge of 19 cubic metres of water per second which enters the plant via a tunnel and then through a wooden penstock. The penstock is 150 metres long and has a diameter of 3.2 metres. Penstocks with this type of construction were widely used in the past, but there are very few still operating today.
