Roselend Dam
Pelton-type
Installed capacity546 MW

The Roselend Dam is an

hydroelectric power generation and supports the 546 MW La Bâthie Power Station.[3]

Design and operation

The dam has a maximum height of 150 m (492 ft) and a length of 804 m (2,638 ft). It is 3 m (10 ft) wide at its crest and 22 m (72 ft) wide at its base. The dam has a structural volume of 945,000 m3 (1,236,013 cu yd). Its reservoir, Lac de Roselend, can store 187,000,000 m3 (151,603 acre⋅ft) of water and has a surface area of 3.2 km2 (1 sq mi). Directly over the river bed is the dam's concrete arch with a 215 m (705 ft) radius. Flanking it on either side are concrete buttresses supporting the dam wall.

Pelton turbine-generators. The difference in elevation between the power station and reservoir affords a hydraulic head (drop) of 1,250 m (4,101 ft).[6] Water from the St. Guerin Dam, 5 km (3 mi) to the southwest at 45°39′00″N 6°34′46″E / 45.65000°N 6.57944°E / 45.65000; 6.57944 (St. Guerin Dam) and Gittaz Dam, 4.5 km (3 mi) to the northeast at 45°42′40″N 6°38′46″E / 45.71111°N 6.64611°E / 45.71111; 6.64611 (Gittaz Dam), provide additional water to Lac de Roselend as well.[3][7]
