Ambitious goals for climate change mitigation and energy security policies are driving deployment of renewable energy sources globally. However, the deployment of renewable energies at scale requires not only public but also private capital, such as foreign direct investment (FDI). Many countries with favourable conditions for renewables, such as the countries of the Middle East and North African (MENA) region, are not attracting sufficient FDI. Risk perceptions of FDI stakeholders are one of the reasons. This paper discusses the de-risking approach as a possible tool to address subjective risk perceptions and assesses with a Computable General Equilibrium (CGE) model macroeconomic feedback-effects of employing a de-risking strategy for FDI into a particular kind of renewable electricity (RES-E) technology, concentrated solar power, in the MENA region. Our results show that the application of a de-risking approach reduces the costs for deployment of CSP, and therefore, also volumes of subsidies that would be needed to make CSP cost competitive with fossil fuel based electricity generation. This, in turn, leads to positive GDP and welfare effects in the MENA region. Our results allow us developing of recommendations for energy policy the implementation of the de-risking approach as a potential consensual option with high political feasibility to reduce climate change mitigation costs.
