Английская Википедия:Andekaleka Dam
Шаблон:Infobox dam 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 Шаблон:Convert headrace tunnel where it reaches a Шаблон:Convert underground power station. After water charges the turbine-generators, it travels down a Шаблон:Convert tailrace tunnel before it reenters the Vohitra River. The drop in elevation between the dam and power station affords a hydraulic head of Шаблон:Convert.[1][2] 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.[3] The power station can house up to four generators. The first two were operational in 1982 and a third in 2012.[4] Generator one and two host Vevey and Jeumont turbines while the third is made by HEC.[5][6] They all use Francis reaction turbines [7] which typically range from 10 to 700MW [8] and with water head operating from 10 to 600 meters [9]
Fire
On 02 January 2022 a fire broke out in its power plant. This caused many black-outs in Antananarivo and its surroundings. The power units will be again functional around mid-June 2022.[10]
