China is building the world’s largest geothermal district heating system in Tibet — using the extraordinary volcanic heat of the Himalayan plateau to warm an entire region that sits at the top of the world.
The Tibetan Plateau is one of the most geothermally active regions on Earth. The collision of the Indian and Eurasian tectonic plates that built the Himalayas over 50 million years created a zone of volcanic activity, hot springs, geysers, and shallow geothermal resources that makes Iceland look geologically modest by comparison. The Yangbajain geothermal field — located 90 kilometres northwest of Lhasa at an altitude of 4,300 metres — is the highest-altitude geothermal power station in the world and has been generating electricity for Lhasa since 1977.
China’s Tibet geothermal program is now expanding far beyond Yangbajain. A new generation of geothermal district heating projects is being developed across the Tibetan cities of Lhasa, Shigatse, Nyingchi, and Nagqu — providing clean heat to communities that have historically relied on coal, yak dung, and imported diesel for space heating in one of the world’s harshest climates. The Chinese Academy of Sciences’ Tibet geothermal research institute has mapped over 400 geothermal fields across the plateau with temperatures sufficient for either heating or electricity generation.
The Xizang Geothermal Energy Development Plan — announced by the Tibet Autonomous Region government — targets 500 MW of geothermal heating capacity and 300 MW of geothermal electricity capacity across the plateau by 2030. The program is being developed with full Chinese state backing as part of the broader western China clean energy development initiative that also encompasses the plateau’s extraordinary solar and wind resources.
