A significant increase in unplanned breakdowns is preventing Eskom from undertaking urgently needed planned maintenance and is leading to a dramatic increase in load shedding.
According to an extensive data investigation by News24, Eskom's leadership between 2015 and 2018 was able to keep the lights on thanks to steadily declining demand, the addition of new generation capacity and a management system which seemingly encouraged power station managers to avoid outages at all costs, even to the detriment of generating units.
On Wednesday, Eskom announced that it would be implementing stage 4 load shedding, because of numerous breakdowns, including a unit at Koeberg nuclear power station being offline, after a fault on a water feed pump that caused the unit to shut down safely.
