Eskom announced that load shedding will continue in Phase 5 until Saturday morning.
After that, phases 4 and 3 will be implemented by 05:00 on Monday.
The embattled power utility has warned that capacity restrictions will continue throughout next week, with current indications that stage 3 of the load shedding will be implemented for most of the week.
The power outage over the weekend will be used to refill the hydro storage dam, which was heavily used last week.
Eskom says it is currently facing constraints from diesel suppliers that are “affecting the availability of bulk diesel fuel for the Ankerlig and Gourikwa open-cycle gas turbines, which have a combined capacity of 2,000 MW. If this diesel supply uncertainty persists, higher levels of load shedding may be required.”
Since Thursday, one generating unit each at the Camden, Creel, Majuba and Matla power stations has been shut down for repairs.
One generator unit at Handrin and two at Kusile power stations were returned to operation.
