The power utility issued an update on Saturday morning.
"Due to a continued shortage of generation capacity, Stage 1 load shedding will be implemented at 17:00 until 22:00 this afternoon. Stage 1 load shedding will be repeated at the same time tomorrow afternoon."
Currently, 4 279 MW is out on planned maintenance and another 15 943 MW is unavailable due to breakdowns.
"We appeal to all South Africans to help limit the impact of the shortages by continuing to reduce the usage of electricity and to switch off all non-essential items," the power utility said.
Eskom spokesperson Sikonathi Mantshantsha said an outlook for the coming week would be given on Sunday.
