China has started to build a massive dam on Tibet’s longest river, a move approved by the central government in December despite concerns by India, Bangladesh and Tibetan rights groups about its impacts on residents and the environment.
The structure is expected to cost more than 1 trillion yuan (US$137 billion). Once completed, it would be the world’s largest hydropower dam, generating 300 billion kilowatt-hours of power annually, about three times the power of China’s Three Gorges Dam, Xinhua, a state-run news agency, reported last year. Operations are expected to begin sometime in the 2030s.
Premier Li Qiang attended a commencement ceremony with other officials in Nyingchi in southeastern Tibet over the weekend.
Xinhua reported that the electricity generated “will be primarily transmitted to other regions for consumption, while also meeting local power needs in Tibet.”
