Construction and background
Golen Gol Hydropower Project is a run-of-the-river project designed for the generation of 108 MW consisting of three vertical Pelton wheel turbine units in one phase with average energy output of 436 Gwh. Golen Gol Hydropower Project is a part of least-cost energy generation plan, being executed by WAPDA to harness the indigenous hydropower resources of the country. WAPDA awarded the contract to SAMBU-SARCO joint venture comprising a Korean and a Pakistani firm. Sambu, an independent power provider (IPP), won the project in the last quarter of 2010 and construction work started in Jan 2011
Sambu has already successfully completed Pakistan's first IPP hydropower plant, 84MW New Bong Escape Hydropower Project, which is commercially operational since March 2013. Korean company has also been awarded a contract to construct Pakistan's third IPP hydropower plant, 100MW Gulpur Hydropower Project on BOOT (Build, Own, Operate, Transfer) basis Joint Venture with other Korean firm and execution of work is in progress.
The Saudi Fund for Development is the major source of funding for the 108-MW Golen Gol hydropower project being developed by Pakistan's WAPDA. The Golen Gol project is also being funded by the Kuwait Fund for Arab Economic Development (KFD) and Organization of the Petroleum Exporting Countries (OPEC). Saudi Fund, Kuwait Fund and Opec Fund are providing $107 million for the construction of GGHPP.
Major benefits and uses
On its completion, Golen Gol Hydropower project will generate about 436 Mega Units (GWH) of inexpensive electricity annually to earn revenue of about Rs 1 billion. Being an environment friendly hydropower project, it will help reduce dependence on expensive thermal power, thereby saving foreign exchange amounting to $34 million (equivalent to Rs 3 billion) to the country. According to estimation, Golen Gol hydropower project will add about Rs 9 billion per annum to the national economy through socio-economic uplift in the country caused by the project.
Construction of Golen Gol Hydropower Plant was commenced in June 2009 and the project is expected to be completed in October 2017. The total cost of the project is about PKR 16 billion. Golen Gol Hydropower Project is part of the least-cost energy generation plan of the Government of Pakistan. It is being executed by Wapda on priority basis to harness indigenous hydropower resources to improve the ratio of hydel electricity in the national grid and help provide relief to the consumers.
Salient features
Type: Concrete Diversion Weir
Diversion Weir Length: 60 m.
Diversion Weir Height: 12 m.
Design Discharge: 30 Cusecs
Headrace Tunnel Length: 3800m long, 3.7m in diameter
Gated Flushing Section Width: 19.72m
Sand Trap: 83.7m
Headrace Channel: 102m
