Hernic Waste Heat Plant is a 26 MW waste power plant in North-West, South Africa. It is operated by Hernic Ferrochrome. Based on its capacity (estimated), it can supply roughly 35,102 homes (estimated). It ranks #88 of 122 South Africa power plants by installed capacity. Commissioned in 2013, it is around 13 years old — relatively modern. In context, the national grid averages 699 gCO₂/kWh (17.8% low-carbon) (2025).

This waste plant recovers energy by combusting municipal or industrial waste. It sits in a humid subtropical (dry winter) climate (Köppen Cwa) — Southern Hemisphere, latitude 25.7°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 75% 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: 22/100 — 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.
