The grid is more sensitive to unexpected disruptions, says Eskom.
Eskom has announced it will implement stage 2 load shedding from 4pm on Tuesday until Thursday.
This, it said, is to manage limited generation capacity and ensure continued supply during the working days.
The decision follows the delayed return of generation units amounting to 3 120MW, as well as an additional loss of 1 385MW in the past 24 hours due to unplanned breakdowns.
“The primary reason for this setback is the delay in returning several units from planned maintenance,” said Eskom.
“These delays, coupled with an unplanned capacity loss that has now temporarily exceeded 13 000MW, align with the risk scenarios shared in our Winter 2025 Outlook.
“Eskom is currently emerging from an intensive maintenance cycle, which is essential for long-term reliability but temporarily reduces system flexibility and resilience. As a result, the grid is more sensitive to unexpected disruptions.”
