Cape Town - Eskom will implement stage 1 load shedding from 17:00 on Tuesday, 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," Eskom said in a statement on Tuesday.

"Eskom would like to assure 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 our supply of electricity 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.
"As we are currently experiencing cold weather conditions across the country, we urge electricity users to consider energy efficient ways of keeping warm," said Eskom.
