That doesn't exclude generation for self-use of course, jus generation and selling to a party that is not Eskom. This will upset those that are beating the drum for an internet of things styley peer-to-peer transmission of energy. Whilst such an idea works on the roads (I can hire fedex to deliver my package to my customer) it does so because the government takes care of all the maintenance of the networks (the roads).
The problem with all this peer-to-peer crypto-energy guff is that it requires exactly the same of the electricity grid, namely that the government says "sure we'll pay for all the transformers and power lines and distribution grids , any amount of power no problem" and that is not realistic even for very advanced grids such as that found in the UK. It might happen if all you are doing is transmitting a few dozen kWh from a roof top power panel to the factory down the road but what happens if I want to tens of MWh of energy from my PV farm in Wales to an eV charging station in the middle of London ?
In SA Eskom and Nersa will always find enough problems to this situation because of the age and relative inflexibility of their grid. Large scales batteries will help them hugely with that, as they will also help organisations such as the mines store energy from PV in the middle of the day for use throughout the evening and night.
