Skollenborg is a typical run-of-river power plant and was built in 1983 to replace the old power plants Labro and Gravenfoss.
The power plant uses a height of fall of 60 metres in the Numedalslågen River and is equipped with two Kaplan turbines which together produce 97 MW. Annual mean production is 395 GWh.
Traces of Norway's first silver mine can be seen in the access tunnel to the power plant.
