Stage 4 load-shedding equates to about 4,000 MegaWatts per hour or 4 GigaWatts per hour of electricity not being available. This is about 20 % of Eskom Power Generation of about 21 GigaWatts. Stage 4 implies 4 million kettles being boiled at the same time. It would take an equivalent to nearly the full installed generating capacity of the giant Medupi power station – which it is now estimated will cost R18 billion to complete.
One could infer that 20% of the business are not operating due to lack of electricity. The question is whether the would be a return on the R18billion investment.
