The Roselend Dam is located in the commune of Beaufort-sur-Doron, in the Beaufortain region of Savoie, between the Col du Pré and the Cormet de Roselend, near the Arêches-Beaufort ski resort. The surrounding mountains reach an altitude of around 2,800 meters. It is part of the Roselend La Bâthie hydroelectric complex, which includes the Roselend Dam and two satellite dams: La Gittaz and Saint-Guérin. This complex is managed by EDF's Alpes Production Unit. The Roselend La Bâthie hydroelectric complex produces the equivalent of the domestic energy consumption of 450,000 residents, thus avoiding the emission of 890,000 tons of CO2 per year. The Roselend Dam is a double-curved arch dam with buttresses. Height = 150 meters Crest length = 804 meters Water reservoir [of the hydroelectric complex] = 187 million m3 The Roselend - La Bâthie development is supplied by the Roselend dam itself, as well as by two satellite dams, La Gittaz and Saint-Guérin. The total storage capacity of these three reservoirs, connected by a system of galleries, is 213 million m3. The water collected at Roselend crosses the massif through a 12.5 km long gallery to flow at an altitude of 1,400 m into the Isère Valley, in the Tarentaise region. It is then transported to the underground plant at La Bâthie via a 2,500 m long penstock, with a drop of 1,200 m. The power plant is equipped with six Pelton-type generating units with a total capacity of 550 MW. Since 2013, EDF has been replacing the main components of each generating unit (turbine, generator, transformer, and energy evacuation cables) to achieve a total capacity of 600 MW by the end of 2018. https://youtu.be/G0Ss9v6wxQQ

At 1,968 meters above sea level, the Cormet de Roselend is a well-known pass in the Alps, located between the two iconic massifs of Beaufortain and Mont Blanc. Its 20 kilometers at a 6.2% gradient from Beaufort make it a first-category pass. Note a flat section at the twelfth kilometer at Lake Roselend, which allows you to admire the lake before beginning the final ascent.

Do not miss the lake and the dam of Roselend after the Col du Pré. Return to Beaufort and Arêches via the Col de Méraillet, whose road is more pleasant downhill.
