In 1902 the very first power plant was built in the Turkish town of Tarsus: a small hydro power plant equipped with an 60 kW Voith Siemens Hydro turbine installed to supply a privately owned textile factory. The beginning of hydro power generation in this small plant in Tarsus also marked the beginning of Voith Siemens Hydro’s presence in the Turkish market – a presence which has continued successfully for 100 years of partnership.
