In 10 years time (maybe even less), these old dinosaur power stations of ours are going to be on their very last legs. If we dont make plans, and fast, to make sure they are all going to be adequately replaced, we will be in a world of hurt that makes stage 8 seem like the good old days. Eskom is still very much a ticking time bomb, no matter how many of the resident experts here think because load shedding is absent, everything is hunky dory and has been fixed.
Judging by how much power was added to the grid in the last 20 years, what will be done in the next 10 is an even scarier thought.
