The Grande Dixence dam, the highest gravity dam in the world, is part of a vast complex which includes four pumping stations (Z'Mutt, Stafel, Ferpècle and Arolla) and three production plants (Fionnay, Nendaz and Bieudron), with a total capacity of 2000 MW.

The Grande Dixence hydroelectric complex thus produces some 2 billion kWh each year and accounts for 20% of Switzerland's storage energy. It supplies the equivalent of 500,000 households with electricity.
