Founded in 1954, Electricité d'Emosson SA, based in Martigny, is the owner of the Emosson hydropower complex, which captures the waters of the Mont Blanc range to supply a lake at an altitude of 1930 metres. This water is then turbined in the power stations of Vallorcine in Haute-Savoie (France) and La Bâtiaz in Martigny (Switzerland). The Swiss firm Alpiq and French firm EDF each own 50% of Electricité d'Emosson SA, and Alpiq has full access to the electricity generated by the two power stations.
