Taming nature and putting its energy to the service of man…it’s a challenge which has been mastered thanks to the construction of hydro-electric barrages.

Three exceptional dams have revolutionized the technique of barrage building and marked their era by engineering records: In 1960, the Barrage of Serre Ponçon was the first of a series of truly gigantic feats. At a height of more than 120 meters, its reservoir constitutes the greatest artificial lake in France. Yet, to achieve this, in the valley below, two villages had to be flooded.

The Barrage of Romanche-Gavet was inaugurated only recently. Since 2020, it stands for a technology without par. It replaces no less than five barrages while being virtually invisible.
