20 Francs Hydropower

Hydropower is one of the oldest energy sources in the world and was already used more than 5,000 years ago. It offers an efficient, climate- and environmentally-friendly form of generating electricity. In Switzerland, the hydropower plant network consists of run-of-river power plants (usually consisting of a barrage formed of a weir in a flowing body of water, for example, river power plants), storage power plants (hydropower plants with natural or artificial water storage reservoirs) and pumped storage power plants (consisting of two water basins located at different heights, for example, Grimsel). A total of 677 plants are in operation throughout the country, producing an average of around 36,741 gigawatt hours of electricity per year and thereby supplying 56% of Switzerland's energy needs. Around 11% of Switzerland's hydropower generation comes from centralised international hydropower plants on border waters.
