Grande Dixence hydroelectric power plants

Grande Dixence consists of multiple power stations linked by underground channels running across vast distances through alpine terrain. The network harnesses elevation changes to direct water through different facilities for electricity production.

The project started in the 1950s as one of Switzerland's most ambitious water management undertakings. It expanded over decades as additional dams and facilities strengthened the nation's power grid.

The valley reveals how people and machines coexist in mountain terrain, with traditional villages standing near modern water management facilities. Locals have integrated these structures into their sense of place, viewing them as part of their regional character.

Visitors can tour the facility in groups on designated days with advance registration required. Sturdy footwear and warm clothing are recommended, as mountain temperatures stay cool even in summer.

One of the facilities uses an exceptional water drop of over 1800 meters to generate power. This height creates one of Europe's most intense conversions of water into electricity.
