Alternative sources of income and the ability to innovate have been essential for the formation of a village society. Årvik is a brilliant example of this, and the ability to use the water as a source of income extends far back in time. Årvik’s history has been characterised by its ability to use water as an energy source from the very first settlement. Permission was granted to operate a sawmill in the river as early as in 1500.

In 2003, landowner Rolf Helge Aanderaa took important steps to realise his wish to put the river to work once again. He acknowledged that it was both challenging and risky to build a power plant on his own, which led him to enter into an agreement with Småkraft. Småkraft provided expertise and capital, and the landowners, Rolf Helge Aanderaa and Signe Kvellestad, provided the water and necessary fall height. Thus the foundation for the power project was laid.
The implementation of the project is an example of good craftsmanship. Årvik is a solid and well-built facility, which has taken the surrounding nature into account. Småkraft converted the former sand pit into a power plant in a way that deserves respect.
By ensuring experienced project management and experienced contractors, the goal of using the river in a good and gentle way has been achieved with a clear margin. The collaboration between Småkraft, landowners and political leaders in Ullensvang municipality has been of inestimable importance in the initial phases of the project.
The Pelton turbine has 6 jets with a maximum discharge capacity of 2.9 m³/sec and drives a generator of 5490 kVA, 6600 V. All power is transformed up to 22 kV and delivered to the grid. The intake dam is built as a gravity dam in reinforced concrete with an intake consisting of a screen and a slide gate. It is adapted to the local terrain. The cast iron penstock with a 1-meter diameter is 890 meters long and is entirely buried.
The power station building is constructed in accordance with Småkraft’s aesthetic guidelines and is 100 m², built above ground in a former gravel pit and well adapted to its surroundings.
To be able to deliver power to the grid, it has been necessary to upgrade the grid between Maurangersnes and Årvik.
