Holen power plant is located at Lake Bossvatn in Bykle Municipality, Aust-Agder County. The power plant is a reservoir plant that uses the height of fall between the Lakes Vatnedalsvatn, Urevatn and Botsvatn in Bykle Municipality.
The first two generating units were commissioned in 1981 and use water from the Lake Vatnedalsvatn reservoir and six tributaries and streams that flow into the service tunnel. The third generating unit was commissioned in 1986 and uses water from Lakes Urevatn, Reinevatn and Skarjesvatn.
All three units are equipped with Francis turbines. The height of fall for generating units 1 and 2 is 316 metres, while the height of fall for the third unit is 651 metres.
Through its ownership in Skagerak Energi AS and Agder Energi AS, Statkraft is co-owner of this power plant. Otra Kraft DA is responsible for daily operations, and manages the licences and obligations in terms of river management and regulating of the watercourse.
