Mae Mah is a 2,400 MW coal power station in Lampang, Thailand. It is operated by Electric Generating Authority of Thailand. Based on its capacity (estimated), it can supply roughly 3,003,428 homes (estimated). It ranks #3 of 196 Thailand power plants by installed capacity. Commissioned in 1995, it is around 31 years old — long-established. In context, coal supplies about 17.8% of Thailand's electricity; the national grid averages 546 gCO₂/kWh (16.6% 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 tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 18.3°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 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.

The #1 largest coal power plant of 5 in Thailand by capacity.
Thailand has 5 coal power plants in this dataset, together about 5,260 MW of capacity.
