Wind power plant in Western Cape, South Africa. Approximate location -34.227, 19.3727.
WindWestern CapeSouth Africa
Dassieklip is a 27 MW wind power plant in Western Cape, South Africa. It is operated by BioTherm Energy. Based on its capacity (estimated), it can supply roughly 22,976 homes (estimated). It ranks #86 of 122 South Africa power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 4.7% of South Africa's electricity; the national grid averages 699 gCO₂/kWh (17.8% low-carbon) (2025).

Operated by BioTherm Energy.
This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Southern Hemisphere, latitude 34.2°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 61% 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: 26/100 — 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.
