View of the dam construction

Tarbela hydropower extension, Pakistan

We carried out detailed design and supervised construction of a new hydropower station and tunnel at Tarbela Dam, enabling water for irrigation to be used for electricity generation as well.

The dam


Tarbela Dam, on the Indus River in Pakistan, is the largest earth fill dam in the world. With a reservoir covering 97 square miles (250 square kilometers) it offers enormous potential for both irrigation and hydropower.


For our client, the Water & Power Development Authority, we provided leading-edge skills to harness this existing resource. Relevant expertise included tunneling, power generation, transmission, irrigation, and community engagement.


At the preliminary design stage, we applied rigorous value engineering to a third party design concept to generate 40% more power using available water resources than originally thought possible.
