  • South Africa’s state owned and state run energy utility, Eskom, reports that Stage 4 loadshedding will continue to be implemented daily until 05:00 on Sunday.
  • Thereafter, Stage 2 loadshedding will be implemented until 16:00.
  • This is necessary due to the need to recover emergency generation reserves, and the generation maintenance to be implemented in preparation for the coming week. 

Breakdowns are currently at 14 953MW of generating capacity while the generating capacity out of service for planned maintenance is 5 914MW.

In the last 12 hours a generating unit at Arnot and Kriel power stations were taken offline for repairs. Subsequently, a generating unit at Arnot, Duvha and Tutuka power stations was returned to service.

The delay in returning to service a generating unit at Kendal and Tutuka Power Stations is also contributing to the current capacity constraints.

Eskom teams are working tirelessly to return these generating units to service.

Eskom’s load forecast for the evening peak demand is 27 639MW and we appeal to the members of the public to continue reducing demand by switching off non-essential appliances.
