We aren't having load shedding because tens of thousands of people are installing embedded generation.
Embedded generation means generation at the point of use, or generation that is embedded inside the grid, rather than Eskom power stations which are at the source generation points on the grid.
Embedded generation including:
solar-electric photovoltaic (PV) systems
wind turbine systems
generators: petrol, diesel
gas-engines (gas generators)
Even without load shedding, electricity prices are incredibly high in South Africa, and the threat of load shedding looms for at least the next 3 years, according to Eskom, and many more years according to me and the Intergrated resource plan
