Stage 2 load-shedding will be implemented from 17:00 on Tuesday due to delays bringing generating units back online, Eskom said in a statement.  Eskom earlier warned that the power system was severely constrained. Breakdowns currently total 15 498 MW of capacity, while another 1 273 MW of capacity is unavailable due to planned maintenance. Unit 1 of the Koeberg power station has been offline since January for maintenance work. It was supposed to return to service last month, but this still hasn’t happened.
