Tekezé Dam is a double-curvature arch dam located between Amhara and Tigray regions 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

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 Tekezé Dam was Africa's largest double-curvature arch dam.[2] The resulting reservoir is 105 km2 large and it has a capacity of 9.3 billion m3 of water.[3]

Tekeze Power Station

The powerhouse contains four 75MW turbines,[2] generating 300MW of electricity. A transmission line connects it to the national grid at Mekelle.[2]
