Newly completed double arch dam. Now Africa's highest.
Tekezé Dam is a double-curvature arch dam in the Tigray region of northern Ethiopia on the Tekezé River, a Nile tributary that flows through one of the deepest canyons in the world. At the time of completion, the 188 metres (617 ft) high dam is said to be Africa's largest arch dam. The dam consists of four turbines, generating 300 MW of electricity together. The dam helped to reduce power shortages as Ethiopia's power demand continues to increase.
