India initiated biggest hydroelectric project in AP

India has started its largest hydropower project, an 11,000 megawatt (MW) installation in Upper Subansiri, Arunachal Pradesh, fearing to China's threat of "water wars."
It is also moving three stalled projects forward for possible allocation to NHPC in response to Chinese dams being built in the northeast, after recommendations from an appraisal committee and in-principle clearance by the ministry of power. According to government sources, a 60,000MW Chinese project on the Yarlung Zangbo (Brahmaputra) planned at Medog on Arunachal Pradesh’s border could be a cause for concern for multiple reasons — scarcity of water if China decides to divert it, floods affecting lakhs in Arunachal Pradesh and Assam if China sudenly releases water, as well as environmental concerns.
For India, the Brahmaputra accounts for nearly 30% of freshwater resources and 40% of total hydro power potential of the country. Almost 50% of the basin of the Brahmaputra is in Chinese territory.
According to sources, the 2,000 MW Lower Subansiri project will be finished in the middle of this year. In addition to producing power, the several hydroelectric projects are anticipated to help reduce water scarcity for up to a year in the event of a Chinese diversion and manage flooding in the event that China releases exceptionally high levels.
The hydro electric projects overdrive in the north-east, and especially in Arunachal Pradesh, which shares its border with China, is seen as strategic move to counter the potential effects of Chinese flow diversion through the dams it is constructing, considering that 50% of the river basin of Brahmaputra is in the Chinese territory.
