Blended Finance and the Diffusion of Renewable Energy Innovation : An exploratory study on bridging the commercialization fundinggap of renewable energy projects in Southeast Asia

Abstract: Blended finance has the past decade become an increasingly popular way for development banks in Southeast Asia to invest in renewable energy projects with the aim of mobilizing additional private investments. Although definitions of the method differ among stakeholders, blended finance is a way of blending development loans with below-market-rate funds to lower risks experienced by private investors. This relatively unexplored financing approach could be one of the solutions to bridge the large private funding gap the region's renewable energy sector is currently experiencing. This paper investigates if and how blended finance contributes to the diffusion of renewable energy innovation in Southeast Asia, through the mobilization of further private investments. To do this, the de-risking effects of blended finance have been investigated, as well as which stage in the diffusion innovation process blended finance is relevant, and how it contributes to the innovation functions of an energy technology innovation system. Exploratory interviews were held with both regional climate finance experts, as well as with eight blended finance investment executives. The findings from this thesis show that blended finance helps renewable energy technologies in their product commercialization and market formation stage, by targeting first-mover projects. During this stage, renewable energy projects in Southeast Asia experience especially high barriers to attracting private investments, the so-called commercialization valley of death. Further, blended finance contributes to four out of seven innovation functions in the energy technology innovation system: Resource mobilization, knowledge diffusion, creation of legitimacy and market creation. The financial risks of renewable energy projects are being mitigated as the public loans and concessional funds lower costs and create increased returns, leading to projects being more financially attractive for private investors. The perceived risks among private investors are being mitigated through knowledge diffusion and the creation of legitimacy. Development banks spread the knowledge about investments in renewable energy projects, as well as the technology, and the very existence of blended finance investment brings a quality mark for renewable energy projects. The paper additionally found that the lack of a common definition of blended finance leads to a lack of common methodologies, data availability and evaluations of the approach. This in turn leads to little research and difficulties in collaboration among blended finance investors, ultimately resulting in the approach being hard to scale.
