Kendal power station — South Africa

Kendal power station is a 4,116 MW coal power station in Mpumalanga, South Africa. It is operated by Eskom. Based on its capacity (estimated), it can supply roughly 5.2 million homes (estimated). It ranks #5 of 152 South Africa power plants by installed capacity. Commissioned in 1990, it is around 36 years old — long-established. Its modelled annual emissions are 18,354,000 t CO₂/yr (Climate TRACE), equivalent to about 4.3 million 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).

In context: how this plant compares

At 4,116 MW, Kendal power station is well above the median coal plant in South Africa (1,180 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

Local climate & thermal context

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 54% 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: 28/100 — this site sits in the bottom third of the power plants we cover by heating degree-days.

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.

Site climate & environmental severity

This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
