Mandraka Power Station
The dam supplies water to a 24 megawatts (32,000 hp) hydroelectric power station 1.9 km (1.2 mi) to the east, down in the valley. The change in elevation between the dam and power station affords a hydraulic head on 226 metres (741 ft).[2][3] The dam and power station are operated and owned by Jirama and the four 6 megawatts (8,000 hp) Pelton turbine-generators were commissioned between 1958 and 1972.[4]
