Eskom has warned that it could be forced to implement load shedding if further generating losses occur.
This comes as the cost of repairing Unit Four at Medupi is being calculated following the hydrogen gas blast.
Eight people who were doing maintenance work on Unit Four have been suspended amid a probe into their actions.
Eskom says a unit at Medupi as well as at Tutuka and Majuba have now also tripped – and a unit at Lethabo has been taken offline for repairs.
The power utility says the grid is currently performing well – but any further loss of generating capacity could necessitate load shedding – which has not been implemented since the 22nd of last month.
