China today partly commissioned its largest hydropower station in Tibet, built on the Brahmaputra river, that could restrict the flow of water in the major river in the riparian regions in India and Bangladesh. The first generating unit of the 9.6 billion yuan ($1.5 billion) Zangmu Hydropower Station, which is positioned over 3,300 metres above sea level on the "roof of the world", went into operation with five other generating units due for completion next year. The huge project, which straddles the middle reaches of the Yarlung Zangbo River, the local name for Brahmaputra will have a total installed capacity of 510,000 kilowatts upon completion. It is designed to generate 2.5 billion kilowatt hours of power annually, Xinhua reported. Reports said besides Zangmu, China is reportedly building few more dams. China seeks to ally the Indian fears of running river projects which are not designed to hold water. The dams also raised concerns in India over their ability to release the water at times of conflict which could pose serious risk of flooding. In Tibet itself the dams sparked off apprehensions over their impact on the fragile environment of the Himalayan region.
