Hummelfossen
As early as 1906 the Matre and Haugsdal waterway was bought up by the businessman Blauuw from Bergen; the first “waterfall speculator” in the Matre area. He immediately resold it to Fr. Hiorth, who transferred all the rights to the company Matrefaldene in 1908. Behind A/S Matrefaldene were German interests, Badische Anilin und Sodafabrik, which wanted to start production of saltpetre fertilizer with nitrogen and electricity.
Tyssedal
Today Tyssedal appears like a classical industrial community, a picture of modern Norway from the turn of the former century until today. A/S Tyssefaldene was established in 1906, and on 1 May 1908 Tyssedal power station was put into operation. The work on the first stage of the facility was completed in a short time, with a work force of 500 men. They built water tunnels, regulation reservoirs, power station, penstocks, harbour, cableways, office buildings, houses and 6 km of power lines in the wild mountains above Odda to provide the new melting plant with power.
