Chances of load shedding are low for the morning, but high for the evening, Eskom warned on Tuesday.
The utility started load shedding again on Sunday evening after ten consecutive days of no load shedding, as it struggles to meet the increased winter demand for electricity.
On Monday Eskom moved quickly from stage 1 to stage 2 “due to a further shortage of generation capacity”.
Eskom said in a statement on Tuesday morning it has adequate generating capacity to meet the demand in electricity.
It however warned that the power system was expected to be constrained during the evening peak period (17:00 – 21:00) mainly as a result of increased electricity demand.
In winter the electricity demand peaks in the morning and evening as more electricity is used during these times, Eskom said, appealing to customers to continue to reduce their electricity usage throughout the day, but to be aware of the need to save more during the peak periods from 06:00 to 10:00 and 17:00 to 21:00.
“As we are currently experiencing cold weather conditions across the country, we urge electricity users to consider energy efficient ways of keeping warm,” Eskom said.
