The original power plant was commissioned in 1918 with three turbines of 9 MW each, and was expanded in 1938 and 1972. The Norwegian state took over the plant in 1964 as a result of right of reversion. Bjølvefossen AS leased the plant until 1997 when Statkraft took over operation and began planning a new plant. The new power plant began production in 2004 with an installed capacity of 98 MW.

New Bjølvo power plant is located inside the mountain with an access tunnel of 1,200 metres from the reception building to the outlet. The old power plant was demolished after extensive historical documentation work was undertaken in 2014 and 2015.

The new Bjølvo power plant was developed to provide energy for the Elkem Bjølvefossen metal smelter in Ålvik.
