I'm on the fence about the guy in general.
On one hand he has reduced Eskom's debt dramatically. He also has seen Eskom through one of the most economically disruptive periods in living memory.
On the other hand he has catastrophically failed to address load shedding in any meaningful way. Losses through unplanned breakdowns are higher than ever with seemingly no concrete plan to make up that lost ground. Excessive increases year on year are ridiculous. I basically pay double what I paid for electricity 5 years ago with ever-degenerating service delivery.
Now that the COVID mess is easing across the world, and that excuse is evaporating for him, I'd like to see what progress he makes towards improving Eskom's generating capacity in the coming year or 2.
