Sundsbarm power plant is located at the old Lakshøl Bruk in Seljord Municipality in Telemark County.

Power: 103 MW

The power plant was commissioned in 1970 and is clearly visible from the E134 motorway. The power plant uses a height of fall of 480 metres from Lake Sunsbarmvatn, the main reservoir for the plant.

The large catchment area covers 418 square kilometres and includes the municipalities of Seljord, Kviteseid, Tokke and Vinje. Water flows from Lake Sundsbarmvatn through a 6.6-kilometre-long service tunnel with sedimentation chamber, surge chamber, protective grate and pipe burst valve. It then flows down into a steel-lined pressure shaft to the power plant.

After the water has passed the plant's Francis turbine, it is discharged through an outlet tunnel into the Vallaråi River, which empties into Lake Seljordsvatn.

The machine hall inside Skorvefjellet mountain is nicknamed the "Skorve Cathedral", which is the venue for an annual Christmas concert enjoyed by the public.

The power plant has an installed capacity of 103 MW.

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.
