Tossevikelva power plant is located in Ringerike municipality in Buskerud. The power plant has an annual production of 6.7 GWh, which corresponds to the electricity consumption of around 444 households.
After a construction period of 11 months, the power plant was put into operation in October 2014. The dam and intake were built in the winter just after Christmas, when there was little water in the river. The spillway of the dam is 15 m long, in addition to a 3-metre spillway by the grate where the minimum water flow comes out (24 l/s in winter and 35 l/s in summer).
The penstock is about 2.7 km with Ø700 mm ductile pipes. The trench primarily contained a combination of rock and soil. The gross head is 307 m.
The power station has a floor area of about 60 m2 and also houses the grid station for Ringeriks Kraft.
A 6-nozzle Pelton turbine has been installed with a turbine capacity of 2.6 MW.
