Årlifoss is the highest of the power plants on the Tinnelva River and was completed back in 1915. This was the first power plant of the Skienfjorden municipal power company, which in 2001 was merged with Vestfold Kraft and became part of Skagerak Energi AS.

Four generating units were in operation until 1989, when a new plant with one generating unit was completed on the east side of the river. In 2003 work was completed to strengthen and expand the flood capacity of the dam. In addition, a roadway was added to the dam.

The height of fall is 16.2 metres.

The power plant is equipped with a Kaplan turbine and has an installed capacity of 22 MW. Annual production is 131 GWh.

Through its majority ownership in Skagerak Energi AS, Statkraft is co-owner of this power plant. Skagerak Kraft AS, a wholly owned subsidiary of Skagerak Energi, is responsible for daily operations, and manages the licences and obligations in terms of river management and regulating of the watercourse.
