Toklev Power Plant is located at the top of the Siljan watercourse and is one of four power stations in this water system.
Toklev Power Plant uses the waterfall between the lakes Sporevann and Vanebuvann. The power plant was refurbished in 2007. The new generators with a Francis turbine replaced two generators that had been at the station since 1921. The flow rate of Toklev is 7.5 m3/s.
The development of the Siljan watercourse was based on a private initiative. Treschow-Fritzøe of Larvik, represented by landowner F.M. Treschow, had seen the great advantages of building a power plant in the watercourse. The power production fit well with the business activity located at the outlet of the watercourse.
In 1911, a decision was made by F.M. Treschow to develop the Siljan watercourse. This development was one of the reasons Vestfold Kraft was founded in 1920.
