The Andekaleka Dam is a gravity dam on the Vohitra River near Andekaleka in eastern Madagascar. The primary purpose of the dam is hydroelectric power generation and it diverts water from the Vohitra east into a 4 kilometres (2.5 mi) headrace tunnel where it reaches a 91 megawatts (122,000 hp) underground power station. After water charges the turbine-generators, it travels down a 500 metres (1,600 ft) tailrace tunnel before it reenters the Vohitra River. The drop in elevation between the dam and power station affords a hydraulic head of 235 metres (771 ft). The dam and power station were funded by the World Bank at a cost of US$142.1 million. It was constructed between 1978 and 1982. The power station can house up to four generators. The first two were operational in 1982 and a third in 2012.
