Before, there were 20 waterfalls from the waterfall bridge in Spydeberg down to Valdisholm. Now there are 4 waterfalls and 3 power plants.
The power plants in Indre Østfold are among Norway's oldest, and Vamma is Norway's largest river power plant.
Vamma power plant is a hydroelectric power plant in Glomma in Indre Østfold and Skiptvet municipality.
The power plant utilizes a drop of 28.5 meters between Kykkelsrud and Vamma. In 1903, the power plant at Kykkelsrud was completed. In 1907, the next big power adventure started up in Askim – Vamma. After a period of discussion, the leading politicians came to the conclusion that a combined development of the waterfalls from Mørkfoss to Solbergfoss should be done together in one power plant. This was completed with its first construction stage in 1924. In 1925, three of the country's largest hydroelectric plants were in operation in Askim and all were Norwegian-owned.
The power plant was started in 1907 by Vamma Fossekompagnie, of which Sam Eyde was the founder, with a view to securing energy for the production of artificial fertilizers. This production never got off the ground and Hafslund took over the plant.
