Wapda completes Allai Khwar hydropower project

The Water and Power Development Authority (Wapda) has successfully completed the 121MW Allai Khwar hydropower project by putting it on mechanical run on Monday.

A spokesperson of the Wapda said that the project will start electricity generation on trial basis by the end of the current month, while commercial generation is planned during the first week of March.

Allai Khwar hydropower project has been constructed on Allai Khwar, a tributary of River Indus in Battagram district of Khyber-Pakhtunkhwa. Main components of the project include 88-metre long and 51-metre high concrete dam, the 2.3 kilometres long steel-lined tunnel, power house comprising two generating units of 61.5MW each, at record design head of 687 metres and a switchyard, he said.

Environment-friendly Allai Khwar hydropower project generates 560 million units of low-cost hydel electricity per annum, resulting in saving of millions of dollars on the corresponding generation of costly thermal energy. Annual benefits of the project have been estimated at around Rs4.5 billion.

Allai Khwar is the second of the three high-head hydropower projects, which has gone operational. The other two include the 72MW Khan Khwar and the 130MW Duber Khwar hydropower projects.

The Khan Khwar hydropower project has already been completed in November 2010, while the third one, Duber Khwar hydropower project, is also near completion, he said.Allai Khwar hydropower project is a part of least-cost energy generation plan of Wapda being executed on priority basis to cope with the increasing needs of electricity and water in the country.

Under the plan, Wapda is working on 26 large and medium-sized projects with cumulative electricity generation capacity of 21,000MW and water storage capacity of 13 million acres feet (MAF). Of these projects, six multipurpose schemes with power generation capacity of over 400MW and water storage capacity of 1.23MAF will be completed in the next two to three months.
