Stage 2 load-shedding will start at 11:00 on Friday, Eskom announced

Three units at the Kendal power station were taken off and it is anticipated that the fourth and remaining unit will also be shut down. The conveyor belts supplying these units are currently not running due to a power fault.

"No coal is reaching the station at this point." Eskom said in a statement.

"We unfortunately do expect the load shedding stage to escalate into the weekend as soon as we have a better understanding of when these problems will be resolved."

In addition, units at the Lethabo and Majuba power stations were delayed in returning to service, and a unit at Tutuka tripped.
