Electricity Minister Kgosientsho Ramokgopa attributed the “unwelcome” ramp up in the intensity of loadshedding to Stage 6 to a need for Eskom to rebuild its emergency reserves that had been depleted by the failure of large coal units during the week and a 1 500 MW spike in demand, which was attributed to the heat-wave conditions affecting parts of the country. Eskom implemented Stage 6 loadshedding at midday on November 24, a period that coincided with the yearly Black Friday retail event, during which shoppers flock to malls to take advantage of price specials.
