Eskom moved to stage 4 load-shedding on Wednesday afternoon  following the breakdown of several units as well as additional demand caused by the cold weather. 

The power utility said stage 4 load-shedding would be implemented from 3pm to 10pm and from 8am to 10pm on Thursday. Constraints on the system are expected to persist for the rest of the week.

Eskom said teams had returned a generation unit each at Tutuka, Komati, Hendrina and the Camden power stations. However, two additional units had suffered breakdowns at the Matla and Kriel power stations.

“[Breakdowns], together with the need to conserve emergency generation reserves, necessitates that load-shedding be implemented in order to protect the integrity of the system,” a statement said.

Eskom had said earlier that a further deterioration in generation performance might necessitate the escalation of load-shedding at short notice.

Unplanned breakdowns amount to 11,300MW of capacity, adding to the 5,040MW out on planned maintenance.
