China’s recently approved a proposal to build a 60-giga-watt dam at the ‘Great Bend’ of the Yarlung Tsangpo River in Tibet has sent shockwaves in India. The highly reactive and securitised nature of Indian policy discourse on China has contributed to the threat perception that the dam shall disrupt India’s access to Brahmaputra waters as a lower riparian vis-à-vis China, or even divert the flow of the river away from the lower reaches of Tibet, to the Chinese province of Xinjiang. However, it may just be the case that this is not so much a national security threat, as it is a potential opportunity for India to build its own hydropower capabilities without worrying about China’s capabilities as an upper riparian.
A dam still on paper
Approved by the Chinese government on December 25, 2024, but only announced to the world in an article appearing in the state-run news media platform Xinhua, the new Great Bend dam is proposed to be the largest in the world. It has the potential to produce three times the energy generation capacity of the second largest dam in the world, the Three Gorges, which is also built in China.
Despite the promise of a massive investment of 1 trillion yuan (~US$ 137 billion), the founding brick for the dam is yet to be laid. And not only has such a dam been under deliberation in China for at least a decade, but the first official confirmation that a hydro-project was in the works at the Great Bend only came with the approval of China’s 14th Five-Year Plan in 2021. Even in the Plan, the proposal makes no mention of a dam on the Great Bend, but a need to create investment opportunities in “hydropower development in the lower reaches of the Yarlung Zangbo River.”
