Cape Town - After a morning of stage 1 load shedding, Eskom on Thursday announced that evening load shedding would move to stage 2 from 5pm to 10pm.
That means it needs to shed 2 000 MW of electricity off the grid in order to meet the demand.
"The cooler weather conditions have put further pressure on an already constrained electricity grid.
"We would like to thank all electricity users for responding to our calls to save and we urge everyone to save as much as they can because every little bit counts.
"We have asked our industrial customers to also contribute towards savings through load curtailment, which goes a long way in addressing capacity constraints.
"The system will be short of 2 000MW this evening, however it is important to note that although certain areas will be without electricity for a certain period, about 93% of South Africans will still continue to receive full power supply at the same time," Eskom said in a statement.
