Answer: Arunachal Pradesh
Notes: The Upper Siang Multipurpose Storage Project in Arunachal Pradesh's Upper Siang district, proposed by NHPC, aims to generate 11,000 MW of power by harnessing the Siang River, a major Brahmaputra tributary. As India's largest hydropower project, it counters similar Chinese initiatives upstream. However, local communities strongly resist it, fearing the submersion of villages, displacement of over 100,000 Adi tribe members, and environmental disruptions in the seismically vulnerable region. Legislative amendments facilitating faster approvals without thorough environmental clearances have intensified opposition. The Siang River, originating near Mount Kailash in Tibet, becomes the Brahmaputra in Assam.
