Jiayuguan - Datang Coal is a 1,200 MW coal power station in Gansu Sheng, China. It is operated by Datang Gansu Power Generation Co Ltd. Based on its capacity (estimated), it can supply roughly 1.5 million homes (estimated). It ranks #843 of 6,685 China power plants by installed capacity. Commissioned in 2004, it is around 22 years old — relatively modern. In context, coal supplies about 54.3% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

In context: how this plant compares
At 1,200 MW, Jiayuguan - Datang Coal is well above the median coal plant in China (700 MW). Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a cold desert climate (Köppen BWk) — Northern Hemisphere, latitude 39.8°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 72% 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: 87/100 — this site sits in the top third of the power plants we cover by heating degree-days.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with dust abrasion the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
How it compares & nearby plants
The #653 largest coal power plant of 1907 in China by capacity.
China has 1907 coal power plants in this dataset, together about 1,882,493 MW of capacity.
