"Due to a shortage of generation capacity, Eskom cautions the public that stage 2 load-shedding might be required ... during the evening peak period of 4pm to midnight over the next three days. Eskom will promptly communicate any further changes," said Eskom.
"The delay in returning a generation unit to service each at Arnot, Kusile and the Koeberg power stations, as well as the failure of a generation unit each at Medupi, Hendrina, Camden and two units at Majuba power station, have exacerbated the capacity constraints.
"Some generation units at other power stations are expected to return to service over the next few days.
"However, should there be any further loss of generation capacity over the next three days, or should some units fail to return to service as anticipated, load-shedding may be required to be implemented at short notice."
