This is the exact reason there's loadshedding in the first place! Too many people have been added to the grid in the past twenty years - much more than the failing grid could ever support. Had they actually taken a page from the old hierarchy's book and upgraded power stations and the grid according to the exponential growth of the population, we wouldn't have this problem. Instead, it was a case of "oh look, we've taken over - let's give EVERYONE electricity at once! Viva!" But of course, like everything else, it was just assumed that the infrastructure would look after itself - roads, schools, electricity, water. "What? You mean someone actually has to plan and maintain all these things?" Added to that the South African attitude of "it's not my job", and we have a country one "human error" (read: Koeberg) away from total collapse.
Sure, go ahead and give 8 municipalities their (free!) power - the rest of us will just sit in the dark.
