Did Yelland select the lead-in photograph for this article?   Concentrated Solar Power (CSP) is scarcely the greatest poster-child for the renewables.
The cost of power generated is strongly influenced by the capital cost of the plant (as reflected in the interest and depreciation-charge calculations), plus maintenance costs, with fuel cost a relatively distant component.  The cost of the Xina-One plant is reported at around R12-billion for a 100 MW plant (Reported as a total of US$880-million; the exact Rand figure depends on the US$ exchange rate used), equivalent to R120-million per MW of nameplate capacity.  On the other hand, the general consensus for the proposed 9 600 MW of nuclear generation is R1-trillion total, equivalent to about R104-million per MW.
