Yunnan Kunming (Sanfeng) power station is a 38 MW biomass power plant in Yunnan, China. It is operated by Chongqing Sanfeng Environment Group Corp Ltd. Based on its capacity (estimated), it can supply roughly 52k homes (estimated). It ranks #4198 of 6,685 China power plants by installed capacity. In context, biomass supplies about 2.0% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

At 38 MW, Yunnan Kunming (Sanfeng) power station is well above the median biomass plant in China (30 MW). Biomass plants burn organic material such as wood, residues or waste-derived fuel to raise steam; they are dispatchable and counted as low-carbon where the feedstock is sustainably sourced.

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a subtropical highland climate (Köppen Cwb) — Northern Hemisphere, latitude 25.1°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 38% 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: 35/100 — 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.
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.
The #179 largest biomass power plant of 981 in China by capacity.
