Eskom has no medium term or long term future.

Technological and busines disrupters will see to that.

Renewable energy is microchip based and subject to a form of moores law - costs per kwh reduce by around 14% every year.

Coal, nuclear and diesel generated electricity cost rise constantly over time.

Utility level battery and other forms of storage of renewables is already a reality - in some new applications in California and South Australia, the cost of renewable generation WITHOUT SUBSIDIES is below the cost of transmision - in other words, even if the ESKOMS of that part of the world generated the electricity for free, it would be cheaper to use renewables owing to the cost of transmission.

Please look up Tony Seba (Stanford University) presentations of "clean disruption" on you tube.

Forget about "we don't need Nuclear", even though it is true.
We don't even need Medupi and Kusile!
