On December 25, 2024, Chinese state media Xinhua reported that the country had officially approved the construction of what will be the world largest hydro-dam with annual capacity of 60 gigawatts (GW), or 300 billion kilowatt-hours of electricity. The planned site is on the lower reaches of the Yarlung Tsangpo River in the Tibet Autonomous Region, in the foothills of the Himalayas.
With recent estimates suggest that the new hydropower dam’s cost to potentially exceed 1 trillion yuan ($137 billion), the planned hydropower dam is expected to surpass the country’s famous Three Gorges Dam as the largest – and most expensive – in the world. The Three Gorges dam cost 254.2 billion yuan and generates 88.2 billion kilowatt-hours annually.
The Power Construction Corporation of China (PowerChina), in partnership with the Tibet Autonomous Region government, is expected to oversee the project. When the proposal was unveiled in late 2020, Yan Zhiyong, chairman of PowerChina, hailed it as an “historic opportunity for the Chinese hydropower industry.”
Chinese officials and media have declared that the day will be a “people-centric project aimed at enriching the people and promoting Tibet’s development.” The hydropower dam’s construction is expected to boost rapid growth in local industries (such as logistics) and also create local employment opportunities.
