Scientific and technical heritage in Aussois
A natural energy reservoir
The Plan d'Amont and Plan d'Aval dams were built in the middle of the twentieth century, and involved a huge amount of work. More than 2,000 workers were on site. A cable car was even built to transport the stones extracted on the Parc des Lozes side to the construction site. The titanic site was even used as a backdrop for the film "La meilleure part", starring Gérard Philippe and Jean Lefebvre.
Fed by mountain streams, the water from the dams is then turbined in the valley's power stations. A scientific heritage to be discovered from the lookout above Plan d'Aval or during a walk on the Plan d'Aval dam, with panels presenting the history of these dams and of hydroelectricity in Haute Maurienne Vanoise. On average, the valley's various facilities produce the equivalent of 2 times the annual residential consumption of the Savoie department.
