Eskom says due to a shortage of generation capacity, Stage 2 load shedding will be implemented from 4 pm to 5 am tomorrow morning.
“We may extend load shedding, since we expect these constraints to persist for the rest of the week. We are currently using emergency generation reserves extensively to supplement supply,” said the electricity giant.
The Power Utility announced on Tuesday that the Kusile power station generation unit tripped, which further compounded the problem, adding that a unit at each of Matimba and Arnot power stations did not return to service.
Eskom said its current breakdowns amount to 17 933MW, while planned maintenance is 3 451MW.
Load shedding is implemented as a last resort to ensure the stability of the power system, according to the electricity company.
“Once again, we apologise for the inconvenience that load shedding has caused the people of South Africa.”
Eskom is urging the public to use electricity sparingly, and will notify the public if any major changes occur to the power system.
