Eskom has announced that it will implement stage 1 load-shedding from 17:00 on Friday, which is likely to continue until 22:00 this evening.
"This is due to increased electricity demand and a shortage of generation capacity resulting from technical faults at some of our power station units," said the power utility.
Eskom assured customers that load shedding is implemented as a necessary measure to protect the power system and to ensure that maintenance is carried out in order to guarantee that electricity supply can be maintained in the long term.
"Any unexpected changes on the vulnerable and constrained power system could lead to a change in the load shedding stage at short notice," said Eskom.
It made a special plea to electricity users to consider energy efficient ways of keeping warm, as cold weather is being experienced across the country.
