In the Haute Tarentaise area, EDF operates a vast hydroelectric power network comprising water abstraction points, dams and plants, including the one at Malgovert. Commissioned in 1953, it channels the water stored in Tignes dam, began in 1948, through turbines (up to 50 m3/s). Thanks to its 4 "double Pelton wheel" units, it can generate around 680 Gwh a year, the equivalent of 280,000 inhabitants' energy consumption (Savoie has a population of 400,000).
