A value proposition of CSP for South Africa

Concentrating solar power (CSP) offers the potential for a high degree of localization and an alternative strategy to meet electricity demand for South Africa in a future of uncertain conventional resources. The integrated resource plan (IRP) makes strides to introduced renewables to the electricity generation system by 2030, but we argue that the proposed mix is too reliant on resources that are not only unsustainable but also at risk in the short to medium term. Coal and other conventional resources may be more limited than originally anticipated, which if true requires action to be taken soon. A balanced mix of PV, wind and CSP can provide the energy supply needed, but steps are needed soon to take advantage of the localization potential and excellent sustainable energy resources.
