Hendrina power station

Coal power plant in Mpumalanga, South Africa. Approximate location -26.0314, 29.6014.

CoalMpumalangaSouth AfricasubcriticalCO₂ modelled

Hendrina power station is a 2,000 MW coal power station in Mpumalanga, South Africa. It is operated by Eskom. Based on its capacity (estimated), it can supply roughly 2.5 million homes (estimated). It ranks #18 of 152 South Africa power plants by installed capacity. Commissioned in 1973, it is around 53 years old — an older, legacy facility. Its modelled annual emissions are 7,308,500 t CO₂/yr (Climate TRACE), equivalent to about 1.7 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).

Data provenance

The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

In context: how this plant compares

At 2,000 MW, Hendrina 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.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

~7,308,500 t CO₂/yr (modelled) — in everyday terms

This facility's annual emissions are roughly equivalent to:

1.7 millionpassenger cars driven for a year
953khomes' yearly energy use
122 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; modelled emissions from Climate TRACE.

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 26.0°S — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 52% 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

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.
