Hydroelectricity has marked the Tarentaise’s history and landscape. From the late 20th century onwards, its development has supported industrial activity in the Valley and tourism in its villages and resorts.Many of the Vallée des Encombres’ springs have been taken in hand, supplying the EDF’s tunnel running beneath your feet to the La Coche dam before the water is turbined in Moûtiers. Above ground, the high-voltage power line is there for all to see, and has been carrying electricity from Albertville (La Bathie) to Italy since 1971.
