I wonder what sort of shift happened in recent history such that S Africa is now a region where “electricity supply is erratic or non-existent.”

What group of people built the "electricity infrastructure" you now enjoy? And if they hadn't built it, do you think you would have access to dependable electricity right now?
What matters is that now the infrastructure is built for all group of people. In 5 years'time, the infrastructure will be completely new [1]. But still, no group of people should claim that they did us a favour by using state's resources to build the infrastructure. It is their job to provide electricity for all citizens.
