Tekezé Dam is a double-curvature arch dam in the northern Tigray region of Ethiopia. It is situated on the Tekezé River, a tributary of the Nile that flows through one of the deepest canyons in the world.

Overview[edit]

CWGS was contracted to build the Tekezé Dam. The hydroelectric project was completed in February 2009. Its final cost was $360 million, which was $136 million over budget. The dam was Ethiopia's largest public works project.[1] The dam helped to reduce power shortages as Ethiopia's power demand increases.

At the time of its completion, the 188 metres (617 ft) Tekezé Dam was Africa's largest arch dam.[2]

Tekeze Power Station[edit]

The powerhouse contains four 75 MW (101,000 hp) turbines,[2] generating 300 MW (400,000 hp) of electricity. A 105 kilometres (65 mi) transmission line connects it to the national grid at Mek'ele.[2]
