Yudean Xinhui power station is a 780 MW gas power station in Guangdong, China. It is operated by Guangdong Yudean Xinhui Power Generation Co Ltd. Based on its capacity (estimated), it can supply roughly 879k homes (estimated). It ranks #1136 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 1,393,800 t CO₂/yr (Climate TRACE), equivalent to about 325k cars driven for a year. In context, gas supplies about 3.2% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

At 780 MW, Yudean Xinhui power station is well above the median gas plant in China (284 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG); Harbin Electric General Gas Turbine (Qinhuangdao) Co., Ltd.:. Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 22.3°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 89% 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: 17/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
A gas turbine here also runs ~5% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).
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.
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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
