description Yangbajain Fumaroles Overview
The Yangbajain geothermal field is located in the Tibet Autonomous Region of China at an altitude of approximately 4,300 meters. It hosts China's first operational geothermal power station, which began generating electricity in 1977 and was developed with technical assistance from the United Nations. The field produces steam and hot water from wells drilled into a high-temperature reservoir, and also supports space heating and greenhouses.
help Yangbajain Fumaroles FAQ
Where are the Yangbajain Fumaroles located?
The Yangbajain geothermal field is in Tibet, China, at an elevation of about 4,300 metres. It lies near the Nyenchen Tanglha range and roughly 90 kilometres southwest of Lhasa. [Lhasa government overview](https://www.lasa.gov.cn/lasa/lsyw/201912/7a3f66e1ead74a4181f029fe23b7d70f.shtml)
Are the Yangbajain Fumaroles part of a volcano?
They are surface signs of a geothermal system, where underground heat drives hot water and steam toward the surface. A fumarole is a vent for steam and volcanic or geothermal gases, so the name describes the feature rather than proving that a large active volcano sits underneath it.
When did Yangbajain begin producing geothermal electricity?
A 1-megawatt test unit at Yangbajain generated electricity in 1977. The site is widely described as Tibet's first geothermal power station and became an important source of electricity for the region.

Why is Yangbajain important to geothermal research?
It combines a high-altitude geothermal field with hot springs, steam vents and a long-running power station. The first 1-megawatt experimental unit in 1977 made the site an early Chinese example of using natural underground heat for electricity.
