Southern Grid Hainan Wenchang Gas power station is a 920 MW gas power station in Hainan, China. It is operated by China Southern Power Grid Peak and Frequency Modulation Power Generation Co Ltd. Based on its capacity (estimated), it can supply roughly 1,036,182 homes (estimated). It ranks #648 of 5,959 China power plants by installed capacity. Its measured emissions of 668,790 t CO₂/yr (Climate TRACE) are equivalent to about 155,895 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).

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 19.8°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 100% 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: 13/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.
In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
A gas turbine here also runs ~7% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

The #46 largest gas power plant of 315 in China by capacity.
China has 315 gas power plants in this dataset, together about 116,718 MW of capacity.
