Eskom announced it would be implementing stage one rotational load-shedding as of Sunday.
The power utility said the power cuts would start at 12.15pm and would continue until 10pm.
Eskom has had to implement stage 1 load-shedding. Apologies for the inconvenience that this will cause,” spokesperson Khulu Phasiwe said.
“Customers are advised to keep checking their load-shedding schedules on the Eskom and their municipal websites, and to plan on the assumption that load shedding will take place,” the company said.
It called on residents and businesses to use electricity sparingly during this time.
“Please switch off geysers as well as non-essential lighting and electricity demand to assist in reducing demand,” Eskom said.
The power utility implements controlled power cuts to prevent the grid from being overwhelmed. Stage 1 power cuts shed up to 1,000 MW from the grid.
Eskom, which supplies more than 90 percent of South Africa’s power, last week warned of potential outages amid low coal inventories after a major supplier cut supplies and sought insolvency protection.
