Kaldsåni power plant

Hovden Farm is located in Hovden in Bykle municipality. Hovden Farm also owns the waterfall rights at Kaldsåni. The landowners realised that the river had a good potential for small-scale power.

In 2008, a contract was signed with Småkraft, which assumed the risk, the work with the licensing process and the development itself. NVE granted a license in 2012. The excavators arrived in 2013. And in 2015, the power plant was rdeliver its contribution in the form of new renewable energy and local business revenues.

With its natural stone walls and a glass façade, the station building has an attractive exterior and has been nicely adapted to the terrain facing Lake Hartevatn.

Fjellgarden Hovden is owned by Sætersdalen AS, a company that is over 100 years old. On the farm there is a residential building, a storehouse, an “eldhus” (fire house), a cabin and an operations building for the feeding of 100 sheep during winter.

THE PROJECT

The implementation of the project has had its challenges along the way, including a hard winter during the construction phase, as well as a short construction season.

Collaboration with the landowners has been good. Their presence and contributions in the form of local knowledge and assistance during both the application phase and the construction phase enabled a smooth project implementation.

The intake dam is built with a concrete threshold to create an intake basin. The intake construction itself is a concrete construction with beam fence, which is integrated into the threshold. The intake is well adapted to the terrain on the site, and appears to be a modest intervention. The penstock is made of GRP pipe and is buried from the intake to the station. It is 1620 metres in length and 800 mm in diameter. The power station building, 100 m2 in size is constructed with the familiar Småkraft design and is well integrated in the terrain. Outflow is led through the channel out into the mouth of the river.
