Yangbajain Geothermal is a 25 MW geothermal power plant in Tibet Autonomous Region, China. Based on its capacity (estimated), it can supply roughly 47,116 homes (estimated). It ranks #4046 of 5,959 China power plants by installed capacity. Commissioned in 1977, it is around 49 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

This geothermal plant taps underground heat to raise steam that drives a turbine. It sits in a polar tundra climate (Köppen ET) — Northern Hemisphere, latitude 30.1°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 170% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 99/100 — this site sits in the top third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
