Construction Commences on Earth's Most Expensive Hydropower Gigantic Structure, Valued at $167 Billion (China)

In a significant move towards its green and low-carbon energy transition, China has initiated the construction of the Yarlung Tsangpo Megadam, the world's largest hydropower dam, located in the lower reaches of the Yarlung Tsangpo River in the Tibet Autonomous Region. With an estimated financial investment of 1.2 trillion yuan ($167.8 billion), this project is substantially more expensive than the Three Gorges Dam.

The megadam, comprising five cascade hydropower stations, is expected to produce approximately 300 billion kilowatt-hours of electricity annually, almost triple the amount generated by the Three Gorges Dam, currently the world record holder. Much of the electricity from the Yarlung Tsangpo megadam will be delivered to other parts of China beyond Tibet.

However, the construction of the Yarlung Tsangpo megadam presents significant geopolitical and water security concerns for both India and Bangladesh, given its location on a transboundary river system. The Yarlung Tsangpo River becomes the Brahmaputra once it enters India and later flows into Bangladesh. The dam will regulate and store water upstream, which could affect the volume, timing, and seasonality of the river flow essential for agriculture, drinking water, and ecosystems in both countries.

India and Bangladesh depend heavily on the Brahmaputra for water supply. Altered flows could disrupt irrigation, fisheries, hydropower generation, and floodplain fertility downstream, raising fears about water scarcity and food security. The dam amplifies China’s strategic leverage over downstream neighbors by controlling a major shared water resource, potentially exacerbating regional tensions and mistrust.

Environmental risks are also a concern, as the dam construction and reservoir could alter local ecology and sediment transport, affecting downstream environmental health. The project aims to improve the local eco-environmental monitoring network system and promote harmony between humanity and nature.

Several of China's downstream neighbors, including India and Bangladesh, have expressed concern about the construction of the Yarlung Tsangpo megadam and its potential impact on their water security. There is currently limited formal water-sharing or dam operation agreements between China and downstream countries, increasing uncertainty about how water release decisions will be managed during droughts or floods.

Despite these concerns, hydropower is considered a renewable and "clean" energy source that doesn't produce direct air or water pollution. Hydropower plants, like the Yarlung Tsangpo megadam, make use of gravity and the kinetic energy of flowing water to spin turbines and generate electricity.

Climate change is driving more intense droughts and widespread water shortages, potentially leading to the rise of "water conflicts" in which states and militia groups vie for control over access to critical water supplies. In this context, the urgency for diplomatic dialogue to address shared water security and ecological sustainability concerns is evident.

Chinese Premier Li Qiang announced the start of construction on July 19 at a groundbreaking ceremony in Nyingchi City, where part of the hydropower system will run through. As the project progresses, it will be crucial to engage in constructive dialogue to address the concerns of downstream countries and ensure a sustainable and peaceful outcome for all parties involved.
