Eskom announced on Thursday, a stage 1 rotary load that will run from 12:00 to 22:00.
The power source stated in its statement that the load was caused by one of its devices being out of planned maintenance.
"Rotating load in Stage 1 requires 1000 MW of full-load load. Load relieving is done as a last resort to protect the energy system from total collapse or blackout," Eskom said.
