The 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 the Indus River in Khyber Pakhtunkhwa province, Pakistan. It is approximately 245 km from the federal capital of Islamabad and 330 km from the provincial capital of Peshawar.^[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 installed at the Allai Khwar Hydroelectric Station, with a total average annual generation yield of 463 million units (GWh) of least expensive electricity.^[3] The project was 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 with the assistance of a local firm, Imperial Construction Company (ICC) from Lahore.
