Heavy winds and rain that subsided on Thursday afternoon led to power outages in parts of the Western Cape.
Eskom says it is working hard to restore the power supply.
These interruptions are not yet the looming load that many people are starting to chew on.
Early in the morning, Eskom warned that there was “a great chance of load shedding during the evening rush hour” from 17:00 to 21:00.
Although the same warning was also sent out on Wednesday, there are now more generating units that are not working.
If it shuts down, it will be the first time since March 15.
The power giant says one unit of the Tutuka power station kicked off, while another was taken off the network.
Also, a unit at the Lethabo power station is not currently supplying power.
In addition, there are delays in getting a unit each back at the Duvha and Kendal power stations.
Eskom warns that any further problems will put it under pressure to generate enough electricity when demand starts rising early in the evening.
Eskom has been warning for several days that he is experiencing problems at his power stations and that there is a chance that he will have to re-apply load shedding.
The news that many South Africans can sit without electricity comes precisely when a large cold front sweeps across the country. Earlier this week, the South African Weather Service (SAWS) warned that icy weather was on its way.
Light snow can occur over the high mountain ranges of the Western Cape, while the mercury in Gauteng is expected to drop to close to 0 ° C overnight.
Eskom warns that the pressure will continue until the weekend.
