“Since [Monday], a generation unit each at Lethabo, Tutuka, Ingula, Drakensberg, Arnot as well as two units each at Hendrina and Matla power stations suffered breakdowns. Further, delays in returning generators to service at Arnot, Kendal and three units at Tutuka power stations have added to the capacity constraints,” Eskom said.
The power utility explained that this led to an unexpected loss of at least 15 067MW of capacity with a further 3875MW of energy on a maintenance outage.
“Eskom expects to return as many of these units to service as possible over the next few days. We also expect to rely on the use of emergency generating reserves to limit the stage of load shedding during this period.
“Eskom would again like to remind the public that load shedding is implemented only as a last resort to protect the national grid. We therefore request the public to continue using electricity sparingly to reduce the occurrence of load shedding. Eskom will promptly inform the public should there be any further significant developments,” Eskom said.
