Ghazi-Barotha Hydropower Project 


is a 1,450 MW run-of-the-river hydropower connected to the Indus River about 10 km (6.2 mi) west of Attock in Punjab, Pakistan. Construction of the project that began in 1995 consists of 5 generators each with a maximum power generation capacity of 290MW. Inauguration of the plant on 19 August 2003 by President General Pervez Musharraf also saw the commissioning of the first 2 of the 5 generators i.e. Unit 1 and Unit 2. The last generator was commissioned on 6 April 2004 and the project was completed by that December. It cost US$2.1 billion with funding from Pakistan's Water and Power Development Authority (WAPDA), the World Bank, Asian Development Bank, Japan Bank for International Cooperation, Kreditanstalt für Wiederaufbau, European Investment Bank and Islamic Development Bank.


About 1,600 cubic meter per second of water is diverted from the Indus River near the town of Ghazi about 7 km downstream of Tarbela Dam (3,478 MW). It then runs through a 100 metre wide and 9 metre deep open power channel which is entirely concrete along its 52 km length down to the village of Barotha where the power complex is located. In the reach from Ghazi to Barotha, the Indus River inclines by 76 meters over a distance of 63 km. After passing through the powerhouse, the water is returned to the Indus. In addition to these main works, transmission lines stretch 225 km.

 

The World Bank classed it "A" for adequate attention to environmental and social issues. The feasibility report was prepared in 1993 during the first tenure of Benazir Bhutto's administration and the Government of Pakistan entered into an agreement for the financing and construction of the project on 7 March 1996.
