Kvernhuselva power plant

Kvernhuselva power plant is located in Gulen municipality in Vestland county.

History


Landowners in Instefjorden entered into an agreement with Småkraft in 2005. The NVE granted a licence for the power plant in 2010. In 2020, a detailed plan and grid agreement were in place, and construction of the Kvernhuselva power plant could begin.

The facility is built with roadless intake just downstream of Storlivatnet lake, 393 meters above sea level. The intake is built on rock, has a low profile and has a neat stone wall around the pool. From the intake, the waterway runs about 700 metres through drilled holes, and then 150 metres of buried penstock to the power plant. The drilled holes contain steel pipes throughout the entire length.
The power plant is nicely situated between two mill houses, and has a glass façade facing the E39 highway and the village.
