Mott MacDonald is design engineer for Tarbela Dam hydro project extension in Pakistan

Mott MacDonald, in a joint venture with Coyne et Bellier of France, has been appointed by the Water and Power Development Authority of Pakistan as design engineer for an extension project at the Tarbela Dam hydropower project, Mott MacDonald reported.

The project, with finance arranged by the World Bank, will extend the power generation facilities at Tarbela Dam, which is situated on the Indus River, 100 kilometers northwest of Islamabad. The extension is expected to add about 1,000 MW of electrical capacity to the national power system.

The dam, completed in 1974, was designed to store water from the River Indus for irrigation, flood control and the generation of hydroelectric power.

The 148 meter high, 3000 meter long dam has two gated spillways and five tunnels that provide irrigation releases and power generation. At the time of construction the dam tunnels 1, 2 and 3 were scheduled for power generation and tunnels 4 and 5 were designed exclusively for irrigation release.

Mott MacDonald has been appointed on the development of existing tunnel 4 which is to be used for power generation and is likely to add two units of 480 MW each to the scheme. Mott MacDonald will carry out a detailed feasibility study to manage the implementation of the extension so that it does not affect the irrigation release and sediment management. This will also include the modification of intake structure, the construction of a powerhouse and the penstock between the outlet of the tunnel and the new powerhouse.

The project is due for completion around 2016 and has an estimated capital value of approximately US$500 million.

Recently, Mott MacDonald announced it will continue to monitor construction of Pakistan’s 84-MW New Bong Escape hydro project, the first private hydropower development in Pakistan to reach financial close.

Mott MacDonald was appointed as lender’s engineer for a consortium of lenders (Asian Development Bank, Habib Bank Limited, Islamic Development Bank, National Bank of Pakistan, International Finance Corporation and Proparco) on the New Bong Escape Hydroelectric Project in 2005. The project was Pakistan’s first private hydroelectric project to reach financial close (December 2009), Mott MacDonald reported.
