The power utility Eskom explained that load-shedding is applied to ensure that the national power system remains stable in case the system struggles to generate enough capacity to keep the lights on countrywide.
These power outages are implemented to protect the power grid from complete failure – which may result in a total nationwide blackout for a prolonged period.
Load-shedding stages
The higher the load-shedding stage, the more frequent residents of the country will experience blackouts. This also means a greater number of citizens will be without electricity for prolonged periods of time across the country.
For example, load-shedding in stage 8 means a greater number of customers countrywide will experience blackouts more frequently and be left in the dark up to 12 hours a day.
Stage 1: allows for up to 1 000 MW of the national load to be shed.
Stage 2: allows for up to 2 000 MW of the national load to be shed.
Stage 3: allows for up to 3 000 MW of the national load to be shed.
Stage 4: allows for up to 4 000 MW of the national load to be shed.
Stages 5: allows for up to 5 000 MW of the national load to be shed.
Stage 6: allows for up to 5 000 MW of the national load to be shed.
Stage 7: allows for up to 7 000 MW of the national load to be shed.
Stage 8: allows for up to 8 000 MW of the national load to be shed.
