Loadshedding was suspended on Sunday morning at 10am.
Eskom said it recovered about 3, 000 Megawatts (MW) of generation capacity and replenished sufficient emergency reserves in the past 44 hours.
Speaking at a media briefing on Saturday, Dr Kgosientsho Ramokgopa, the Minister of Electricity and Energy, said about 17,000 MW were lost in the last week.
Loadshedding stage 3 was expected to end on Monday, at 5am.
Dr Ramokgopa said he would go back to Eskom to try establish the root cause of loadshedding after more than 300 days of progress.
At the same briefing, Dan Marokane, CEO of Eskom, said 3,200 MW were retained on Saturday morning, including 2 units at Kusile. Another 2,800 MW were returned sooner to the system.
He said Eskom is working hard to bring Kusile Unit 6 back to the system and have it synchronized by mid March 2025.
Bheki Nxumalo, Executive for Generation at Eskom, said his teams are working hard to bring Medupi Unit 4 back to the system at the start of April 2025.
He also said good weather has boosted these efforts, and in addition, maintenance would be spread across all seasons from now on.
Another step in the right direction, is the re-introduction of an independent service provider to alert management and the board of red flags, Mtetho Nyathi, Board Chairperson, said.
He said Eskom had failed three times, which is unacceptable and that a stick approach would be used, as much as the carrot, in supporting management.
Progress on the recovery of Koeberg Unit 2 is also reportedly underway to restore 4,091 MW back to service by Monday.
