The Kinnforsen power station is located 300 metres upstream of the intake to the Kvassteinåga power plant. The power plant utilises a 163-metre waterfall at an elevation of 329, while the power station is at an elevation of 166. The waterway consists of a 1450-metre buried penstock with a diameter of 1 m. Øijord & Aanes were the general contractors for the project.
Fagbygg was the subcontractor for the construction of the power station and intake. Electromechanical equipment was supplied by Spetals Verk, while Brødrene Dahl supplied the equipment for the waterway.
