Dagang Oilfield captive power station is a 50 MW coal power plant in Tianjin, China. It is operated by PetroChina Dagang Oilfield Branch [100%]. Based on its capacity (estimated), it can supply roughly 63k homes (estimated). It ranks #3532 of 6,685 China power plants by installed capacity. In context, coal supplies about 54.3% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

At 50 MW, Dagang Oilfield captive power station is below the median coal plant in China (700 MW). Technically it is described as subcritical. 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.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a monsoon hot-summer continental climate (Köppen Dwa) — Northern Hemisphere, latitude 38.7°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).
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 corrosive environment (estimated ISO 9223 class C4 — High), with thermal cycling 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.
The #1836 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.
