Cape Town - Eskom has implemented stage 1 load shedding from 09:35 on Thursday, which is likely to continue until 22:00 this evening.
"This is due to increased electricity demand due to the cold front that is currently sweeping through the country and a shortage of generation capacity resulting from technical faults at some of our units," Eskom said in a statement.
"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."
