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 was Africa's largest arch dam.[1] The powerhouse contains four 75 MW turbines,[1] generating 300 MW of electricity altogether. A 105 kilometres (65 mi) transmission line connects it to the national grid at Mek'ele.[1]

The Tekeze hydroelectric was competed in February 2009.[1] The final cost was $360 million which was $136 million over budget. It was Ethiopia's largest public works project.[1] The dam helped to reduce power shortages as Ethiopia's power demand increases.

Background[edit]

The Tekeze Hydro Electric project constructed the highest double curve arch dam in Africa, topping the previous highest, the 185 metres (607 ft) Katse Dam in Lesotho.[1] The contractors behind the project were CWGS.
