Mailao is a 4,200 MW coal power station in Taiwan, Taiwan. It is operated by Formosa Plastics Group (Mailiao Power Corp). Based on its capacity (estimated), it can supply roughly 5,256,000 homes (estimated). It ranks #3 of 39 Taiwan power plants by installed capacity. In context, coal supplies about 36.3% of Taiwan's electricity; the national grid averages 633 gCO₂/kWh (13.4% low-carbon) (2025).

~18,396,000 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

4,288,112passenger cars driven for a year
2,399,061homes' yearly energy use
306,600,000tree seedlings grown 10 years to absorb it

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.

Local climate & thermal context

This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Northern Hemisphere, latitude 23.8°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 95% 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: 16/100 — 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.
