Génissiat, a fascinating industrial structure

Come and discover how water is transformed into 100% renewable electricity at our site of Génissiat with its dam and hydropower plant.

This structure is an unmissable site of the industrial landscape of the Upper Rhone. Located between Ain and Haute-Savoie, it was inaugurated in 1948. Called the “French Niagara” due to the height of its head (fall), it is the result of a gigantic construction project begun in 1937 and continued during the Second World War. The largest hydroelectricity dam-plant in Europe at the time it supplied Paris with electricity from 1948 onwards.
