Following the implementation of load shedding on Thursday, Eskom said it will continue with Stage 2 load shedding through to Sunday night.
“The loadshedding is necessary due to loss of generation capacity overnight,” Eskom said.
“Loadshedding is also required to manage the use of the emergency reserves, which will help us contain the stage of loadshedding required.
“The system remains vulnerable and unpredictable, should any further breakdowns occur, the stage of loadshedding may change at short notice.”
Eskom said that two generation units at the Kusile Power Station tripped due to the failure of the main coal feed conveyor belts supplying coal to the units.
“In addition, a unit each at the Kriel and Duvha tripped due to unforeseen breakdowns. We presently have four generation units whose return to service from planned maintenance has been delayed,” the utility added.
“We currently have 5 358MW on planned maintenance, while another 14 748MW of capacity is unavailable due to unplanned maintenance, breakdowns and the outage delays mentioned above.
“Eskom personnel are working tirelessly to return as much of this capacity to service as soon as possible.”
The power utility urged the public to reduce electricity consumption in order to help minimize loadshedding.
“Eskom will communicate timeously should there be any significant changes to the power system.”
