Komati Power Station is a 1,000 MW coal power station in Mpumalanga, South Africa. It is operated by Eskom. Based on its capacity (estimated), it can supply roughly 1,251,428 homes (estimated). It ranks #17 of 122 South Africa power plants by installed capacity. Commissioned in 1963, it is around 63 years old — an older, legacy facility. In context, coal supplies about 81.4% of South Africa's electricity; the national grid averages 699 gCO₂/kWh (17.8% 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 subtropical highland climate (Köppen Cwb) — Southern Hemisphere, latitude 26.1°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 48% 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: 30/100 — 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 #14 largest coal power plant of 18 in South Africa by capacity.
South Africa has 18 coal power plants in this dataset, together about 44,563 MW of capacity.
