Allai Khwar Hydropower Plant is a run-of-the-river, high head project of 687 metres, located in the Battagram District on the Allai Khwar River, a left bank tributary of Indus River in NWFP Province. It is approximately 245 km from the federal capital of Islamabad and 330 km from the provincial capital of Peshawar, in the Islamic Republic of Pakistan.[1]

The total electricity generation capacity of the Allai Khwar Plant is 121 MW.[2] There are two Pelton-type turbine based electricity generating units of 60.5 MW each installed at Allai Khwar Hydroelectric Station with the total average annual generation yield of 463 million units (GWh) of least expensive electricity.[3] The project is completed by the technical assistance of international corporations via a consortium between local and Chinese firms headed by Dongfang Electric which was responsible for the civil works. The E&M works were carried out by Andritz Hydro GmbH Austria. The transmission line was laid by the North East China Electric Power Corporation along with the assistance of a local firm Imperial Construction Company (ICC) from Lahore.

Financing[edit]

Islamic Development Bank (IDB) provided a loan of US $38.435 Millions from July 2009 onwards to complete the remaining works on the project. The total cost of the project is estimated to be PKR 13.8 billions. The annual benefits of the project are estimated to be around PKR 4.5 billions.[4]

Construction[edit]

Construction of Khan Khwar Hydropower Plant was commenced in January 2005 and the project was completed in March 2013. Power House is in commercial operation since 25 March 2010. The project was officially inaugurated on 4 March 2013 by President of Pakistan Asif Ali Zardari.[5] The Chinese firm handed over the Project to Water and Power Development Authority on October 8, 2013.[6]
