Load shedding is a euphemism for a planned power failure, and while highly disruptive, is preferable to having the country's power grid shut down if the demand exceeds supply.
The national energy supplier Eskom monitors the demand for electricity and their ability to supply it. This monitoring is made public via the Power Alert website and has three levels before load shedding is required.
- Green - Grid is stable - avoid unnecessary power use
- Yellow - Grid is under pressure - reduce unnecessary energy use
- Red - Grid is nearing capacity - turn off power intensive appliances
