In context: how this plant compares
At 700 MW, Longmay Shuangyashan power station is around the median coal plant in China (700 MW). Technically it is described as supercritical. 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.

Climate zone & how it works
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a monsoon warm-summer continental climate (Köppen Dwb) — Northern Hemisphere, latitude 46.6°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
Site climate & environmental severity
This site sits in a benign, low-corrosion environment (estimated ISO 9223 class C1 — Very low), with thermal cycling 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 #974 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.
