I lived in South Africa for 14 years and left when load shedding was just getting established. South africa was busy building more and larger coal fired generating plants and that was supposed to be the solution. My wife is South African and her family lives with the increasing frequency and duration of load shedding. I think you are right, that it is a coming attraction and that there are as the song goes, no hiding places (Simon and Garfunkle - save the life of my child)
