Nuclear power plants are cheap to run, but expensive to build. The reason why the Koeberg generation rate (as Eskom calculates it) is so low is because of their principle of "sunk cost". They do that with coal as well. Running cost per kWh is about R0.30 for coal, because maintenance is not discounted. So, it costs them less per day than new RE projects, at R0.62. This excludes the cost of stand by or baseline. The estimates for new coal is R 1.05 and New nuclear R 1.30. All probably based on optimistic build cost forecasts. This paints a very bleak picture. (The figures are from memory and not researched. I will not claim any degree of accuracy).

Our industrial base was destroyed, first by the 2008 disruptions and then by the price increases allowed. At current delivered prices, industrialising is impossible. Nuclear won't stimulate it. Demand must come first, supplied by the cheapest generating option, in modular mode, by RE and gas. Small quickly built plants with short horizons.
