When there is insufficient power station capacity to supply the demand (load) from all customers, the electricity system can become unstable, possibly resulting in a national black-out. To avoid this, Eskom either increases supply or reduces demand. To increase supply, Eskom runs its power stations at maximum available capacity. To reduce demand, Eskom first calls on customer contracts that allow for supply to be reduced or interrupted for specific periods and durations. If this is not enough, Eskom is forced to cut supply to all other customers. This can be done through either ‘scheduled’ or ‘emergency’ loadshedding
