Wapda to initiate three hydropower projects

With a view to meeting the ever-increasing needs of electricity and water in the country, the Water and Power Development Authority (Wapda) is going to start construction work on three more projects in couple of months, as all pre-requisites for initiation of these projects are almost complete.

According to a statement issued Tuesday, with a cumulative generation capacity of about 1540 megawatts and gross water storage capacity of 250,000 acres feet, these projects include two hydropower projects namely Tarbela 4th Extension and Keyal Khwar, and one medium-sized dam i.e. Naulong.

The projects are part of Wapda’s least cost energy generation and water storage plan, under which 26 projects of more than 21,000 MW power generation and 13 MAF water storage capacity are in various phases of their implementation.

The 1410 MW-Tarbela 4th Extension Project is being undertaken as the 4th extension of Tarbela hydel power station. Three generating units, 470 MW, each will be installed to raise the capacity of Tarbela power station from 3478 to 4888 MW. Annual energy contribution of Tarbela 4th Extension Project has been estimated at 3480 million units and annual benefits at Rs30 billion.

The World Bank is providing $ 840 million for construction of the project. Keyal Khwar hydropower project is located on Keyal Khwar, a right tributary of River Indus in Dasu district of Khyber Pakhtunkhwa. Power generation capacity of the project is 122 MW with annual energy contribution of about 426 million units of low-cost electricity to the National Grid with estimated annual benefits of about Rs3.5 billion.

Naulong Dam is located on Mula River in Jhal Magsi district of Balochistan. The project, with a water storage capacity of nearly 250,000 acre feet, will irrigate 47,000 acres of land. In addition, 4.4 MW electricity will also be generated. Benefits of the project have been calculated at more than Rs2.5 billion per annum.

Wapda has already started construction work on Golen Gol hydropower project and Nai Gaj dam. The 106 MW-Golen Gol hydropower project is being constructed on the River Golen Gol, a major tributary of the River Mastuj in Chitral district of Khyber Pakhtunkhwa.

On completion, the project will generate about 436 million units of electricity annually. Likewise, Nai Gaj Dam Project is being constructed across Gaj River in Dadu district of Sindh. The 194 feet high dam will store 300,000 acre feet of water to irrigate about 40,000 acres of land. Besides, the project will also generate 4.2 MW electricity. Annual benefits of the project have been estimated at about Rs3.5 billion.
