China Launches World’s Largest Hydro-Power Project

Chinese Premier Li Qiang has announced the formal launch of a massive hydroelectric project on the Yarlung Tsangpo River in Tibet.

To mark the occasion, a groundbreaking ceremony took place on July 19, 2025, in the southeastern Tibetan city of Nyingchi near the Indian border.

According to reports, the project is expected to be the world’s largest hydro-power facility upon completion, with a projected annual electricity output of 300 billion kilowatt-hours. That’s around three times the capacity of China’s existing Three Gorges Dam. I

The Yarlung Tsangpo River originates on the Tibetan Plateau and becomes the Brahmaputra River as it flows into India’s northeastern states of Arunachal Pradesh and Assam before continuing into Bangladesh.

Owing to the trans-boundary nature of the river, China’s move has raised concerns in both India and Bangladesh regarding the downstream effects of the project. Particularly in terms of water availability, agricultural impact, and environmental disruption.

According to reports, the dam will consist of five cascade hydro-power stations, requiring a total estimated investment of 1.2 trillion yuan (approximately $167 billion).

The primary purpose of the project is to generate electricity for external markets, though it is also expected to meet some local energy needs in Tibet.

In a bid to quell regional anxiety, China has stated that the project has already been subject to comprehensive scientific assessment to ensure it would not negatively impact downstream ecosystems, geological stability, or the water rights of neighboring countries.

The Chinese foreign ministry has also been quick to point out that the dam will contribute to disaster prevention, climate change adaptation, and regional energy cooperation. The ministry further stated that the dam project will not be used for political leverage.

To manage the massive undertaking logistically, China has established a new state-owned enterprise named the China Yajiang Group, which will serve as the official project owner. The new company will be responsible for construction, operation, and ensuring environmental protections.

Speaking during the company’s inauguration, China’s vice-Premier Zhang Guoqing underscored the importance of technological innovation and ecological safeguards.

While Beijing frames the project as a forward-looking solution for clean energy and regional development, it continues to fuel tension and uncertainty in a region already marked by sensitive water politics and unresolved border conflicts.
