Eskom CEO Andre de Ruyter reports that action will be taken against management at some power stations after an unexpectedly sharp deterioration in the performance of certain coal-fired generators on Monday, which precipitated the re-introduction of load-shedding only 24 hours after rotational cuts were initially suspended. Load-shedding was re-instated at 21:00 on Monday February 7 after full and partial unplanned breakdowns surged to nearly 16 000 MW at a time when more than 3 300 MW was down for planned outages.
