Eskom announced late on Saturday evening that no load shedding was planned for Sunday.
The embattled power utility said however, that the power system remained constrained, and load shedding may be implemented at short notice.
Last week, Eskom blamed the implementation of load shedding, which began on Wednesday, on boiler leaks and the breakdown of a conveyor belt transporting coal to Medupi power station.
It added that delays in returning units that were on planned maintenance to service, contributed to supply constraints, as did diesel shortages.
