The Bonnevaux hydroelectric power station, known as the Pont de l’Eau Noire plant, is a recognized heritage site.
Commissioned in 1909, this hydroelectric power station is one of three in the Dranses region to generate renewable electricity from the river.
The Pays d’art et d’ histoire de Leman Mountains Explore organizes an occasional “Send the watts” tour of the Bonnevaux power station.
