Eskom said on Wednesday it will implement stage 1 load-shedding from 17:00, which will likely continue until 22:00.
It said the power system was constrained but stable for most of the day, thus enabling Eskom to perform maintenance without the need for load-shedding.
"However, due to increased electricity demand and a shortage of generation capacity due to power station units being on maintenance, Eskom will implement stage 1 load-shedding from 17:00."
The utility warned that any unexpected changes on the vulnerable and constrained power system could lead to a change in the load-shedding stage at short notice.
As the cold weather is contributing to the increased demand on the grid, Eskom urged electricity users to consider energy efficient ways of keeping warm.
