Coal power plant in Mpumalanga, South Africa. Approximate location -26.7767, 29.3527.
CoalMpumalangaSouth AfricaCO₂ reported
Tutuka power station is a 3,654 MW coal power station in Mpumalanga, South Africa. It is operated by Eskom. Based on its capacity (estimated), it can supply roughly 4,572,720 homes (estimated). It ranks #6 of 122 South Africa power plants by installed capacity. Commissioned in 1987, it is around 39 years old — long-established. Its measured emissions of 13,506,600 t CO₂/yr (Climate TRACE) are equivalent to about 3,148,392 cars driven for a year. 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 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 26.8°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.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
The #6 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.
