SASOL ONE is a 314.5 MW other power station in Orange Free State, South Africa. Based on its capacity (estimated), it can supply roughly 236k homes (estimated). It ranks #52 of 152 South Africa power plants by installed capacity. Its modelled annual emissions are 622,020 t CO₂/yr (Climate TRACE), equivalent to about 145k cars driven for a year. In context, the national grid averages 699 gCO₂/kWh (17.8% low-carbon) (2025).

Known, modelled and calculated values are kept separate. Missing fields are shown as unavailable.
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.

This facility converts its energy source into electricity for the grid; its capacity, fuel type and location determine its role in the national power mix.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.
This facility's annual emissions are roughly equivalent to:

This other plant generates electricity for the grid. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — 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 56% 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: 27/100 — 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.
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.
