Suiyang power station is a 300 MW coal power station in Guizhou Sheng, China. It is operated by State Power Investment Corporation Guizhou Jinyuan Suiyang Industrial Co Ltd. Based on its capacity (estimated), it can supply roughly 375k homes (estimated). It ranks #1914 of 6,685 China power plants by installed capacity. Commissioned in 2018, it is around 8 years old — recently built. Its modelled annual emissions are 970,880 t CO₂/yr (Climate TRACE), equivalent to about 226k cars driven for a year. 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 300 MW, Suiyang power station is below 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.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 27.9°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 31% below 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: 38/100 — this site sits in the mid 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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
