Yixing - Union 1-4 Coal is a 150 MW coal power station in Jiangsu Sheng, China. It is operated by Union Energy Co. Based on its capacity (estimated), it can supply roughly 187,714 homes (estimated). It ranks #1679 of 5,959 China power plants by installed capacity. Commissioned in 1995, it is around 31 years old — long-established. In context, coal supplies about 54.3% of China's electricity; the national grid averages 525 gCO₂/kWh (41.7% low-carbon) (2025).

This facility's annual emissions are roughly equivalent to:
Estimated, not measured: from installed capacity at a typical 50% load factor × a typical coal emission factor (~1000 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 31.4°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 27% 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: 39/100 — this site sits in the mid 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.
