Eskom has announced it will implement stage 3 load shedding on Tuesday.
On Monday, the power utility went from implementing stage 2 load shedding to stage 4 load shedding.
It cited failure of a number of generating units.
State 3 allows for 3000 megawatts to be cut from the national grid.
Eskom spokesperson Khulu Phasiwe tweeted on Tuesday morning that Eskom would be implement stage 3 loadshedding from 08:00 until 23:00.
“The power system remains constrained. We'll continue to provide regular updates about the state of the power system through various media platforms,” Phasiwe said.
Eskom's board said the Medupi and Kusile power stations show a lack of reliability to contribute meaningfully to Eskom’s generating capacity.
President Ramaphosa said the rotational load shedding came as a shock.
