Coal power plant in Chongqing Shi, China. Approximate location 30.1621, 106.5474.

CoalChongqing ShiChinaultra-supercriticalCO₂ modelled

Chongqing Shuanghuai power station is a 1,920 MW coal power station in Chongqing Shi, China. It is operated by China Power Investment Corporation (CPI). Based on its capacity (estimated), it can supply roughly 2.4 million homes (estimated). It ranks #422 of 6,685 China power plants by installed capacity. Commissioned in 2011, it is around 15 years old — relatively modern. Its modelled annual emissions are 8,058,200 t CO₂/yr (Climate TRACE), equivalent to about 1.9 million 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 1,920 MW, Chongqing Shuanghuai power station is well above the median coal plant in China (700 MW). Technically it is described as ultra-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.

~8,058,200 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

1.9 millionpassenger cars driven for a year
1.1 millionhomes' yearly energy use
134 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.

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 (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 30.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 46% 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: 31/100 — this site sits in the bottom 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

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.
