Power utility Eskom says says it is not planning any power cuts for Wednesday after the country's generation capacity improved.
Eskom instituted load shedding overnight, which was suspended at 5 a.m.
The utility said that generation units at the Tutuka, Duvha, Medupi and Hendrina power stations were successfully returned to service, which helped boost capacity. A further two units are expected to return to service later on Wednesday.
But it has warned that it may again implement electricity rationing at short notice.
"As previously communicated, the possibility of load shedding remains elevated while Eskom continues to implement reliability maintenance, and as such the system will continue to be constrained during this period."
