Tyssedal

Tyssedal is a typical monotown, depending upon the energy received from the hydropower station. The first hydropower station in Tyssedal, Tysso I, is today part of the Norwegian Museum of Hydropower and Industry. The ilmenite smelter "Tinfos Titan and Iron" (TTI) (once owned by Tinfos, known as the Eramet Titanium & Iron plant) is located here and is the largest employer in the village. The smelter was converted from making aluminium in the late 1980s. Tyssedal grew up around this smelter in the early-twentieth century. In 2024 Eramet sold its plant to Ineos Enterprises for $245 million. ==Language==

Tyssedal drew migrants from different parts of Norway, who spoke different Norwegian dialects. From these there developed a compromise dialect, what linguists call a koiné language. Tyssedal and the nearby town of Odda—which arose in the same time and socio-economic circumstances but from a more homogeneous population—provided valuable insights to linguists studying this phenomenon. Professor Paul Kerswill conducted an intensive study of the Norwegian spoken in the two communities, relating them to very different geographical origins: The workers in Odda came predominantly (86%) from western Norway. In Tyssedal only about one third came from western Norway; one third came from eastern Norway; and the rest from other parts of the country. The dialects that evolved in these two communities were radically different from each other, though spoken at a short geographical distance from each other. ==See also==
