Situated at an altitude of 1,930 metres, the Emosson reservoir is partly fed by the waters of the Mont Blanc massif. Energy is generated in the Vallorcine and Martigny-La Bâtiaz stations located around 1,400 meters lower down. The water stored in the reservoir is sufficient to generate electricity to illuminate a city of 250,000 residents.
