The Cahora Bassa Dam on the Zambezi River in Tete Province is one of the largest hydroelectric projects in Africa. Constructed between 1969 and 1974, this double-curvature arch dam stands at an impressive height of 171 meters with a crest length of 303 meters. The power station has an installed capacity of 2,075 megawatts, making it one of the primary energy sources for Southern Africa. A significant portion of the electricity generated is exported to South Africa via high-voltage direct current (HVDC) transmission lines. The resulting reservoir covers approximately 2,700 square kilometers, ranking as Africa's fourth-largest artificial lake. Beyond power generation, the dam supports commercial fishing and navigation, though it significantly impacts the ecology of the lower Zambezi basin. Control over the dam remained a complex diplomatic issue with Portugal after independence, only reaching a final resolution in 2007 when the Mozambican state acquired the majority shareholding.
