Stage 1 loadshedding will continue to be implemented daily from 05:00 to 16:00 until Sunday, Eskom said on Friday.
Meanwhile, Stage 2 loadshedding will also continue to be implemented daily at 16:00 to 05:00 until Monday.
The ongoing load shedding is mainly due to the need to preserve emergency generation reserves owing to a high level of breakdowns and the delay in returning some generating units to service, Eskom said. Since Thursday morning a generating unit each at Camden, Duvha, Kusile and Majuba power stations were taken offline for repairs.
The delay in the return to service of a generating unit each at Majuba and Tutuka power stations also contributed to the generation capacity shortages. A generating unit at Hendrina power station was returned to service.
Currently, 4 846 MW are on planned maintenance, while another 14 509 MW of capacity is unavailable due to breakdowns.
