The Capanda Dam is a hydroelectric dam on the Kwanza River in Malanje Province, Angola. Built in 1987–2007 years the Russian company Tekhnopromexport, general designer - the institute Hydroproject (Chief Engineer - Ph.D Fedosov V.E.) The facility generates power by utilizing four turbines and 130 megawatts (170,000 hp) each, totalling the installed capacity to 520 megawatts (700,000 hp) . Total cost of US$4 billion. An additional cost of more than US$400 million was spent in repairing the damage caused during UNITA's occupation of the area at the time of the Angolan Civil War in 1992 and 1999.
The principal structures include:
As of 2013 Capanda HPP generates more than half of all electricity in Angola and is the largest hydroelectric complex in the country
On September 2, 1982 Angola signed an intergovernmental Soviet-Angolan agreement for the framework contract, for the construction of a hydropower dam. The Ministry of Energy and Petroleum of Angola, formed a cabinet management group to manage construction for the Central Kwanza (GAMEK) contractor consortium of Capanda, which included the Soviet foreign trade association "Tekhnopromexport", and the Brazilian construction firm Odebrecht.
The first draft and the first topographic surveys on the alignment of the dam, were made in 1965 by the Portuguese COBA company. This project involved the construction of an arch dam, based on two gravity abutments. This project was scrapped by Soviet specialists and construction costs were later significantly reduced. Project Capanda HPP 520 MW was completed in 1989. The successfully project passed inspection by the state experts from the organizations of USSR, Angola and Brazil.
Construction began in January 1987. The Contract provided for the completion of the dam by the end of 1992. From April to October 1988, the construction of the tunnel excavation was completed. At the end of June 1989, the River Kwanzaa was blocked, and the water flowed into the tunnel. The filling of the reservoir was completed on September 1, 1992.
