Ulaanbaatar-4 Thermal Power Plant is a 570 MW coal power station in Ulaanbaatar, Mongolia. It is operated by Thermal Power Plant-4 SSH Co. Based on its capacity (estimated), it can supply roughly 713,314 homes (estimated). It ranks #1 of 8 Mongolia power plants by installed capacity. Commissioned in 1984, it is around 42 years old — long-established. In context, coal supplies about 85.8% of Mongolia's electricity; the national grid averages 816 gCO₂/kWh (8.4% 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 47.9°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 198% above 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: 100/100 — this site sits in the top 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 3 in Mongolia by capacity.
Mongolia has 3 coal power plants in this dataset, together about 804 MW of capacity.
