Researchers from the Faculty of Economics and Business, University of Zaragoza, Spain examine how different risk allocation strategies in renewable energy projects affect the amount of private investment in such projects, particularly those involving both public and private sectors. By analyzing 2,215 projects in 73 developing countries from 1997 to 2019, which include technologies like solar, hydro, wind, waste, biogas, biomass, and geothermal, the study finds that projects where private partners take on more responsibilities tend to attract more private investment. Additionally, several project-level and institutional factors also drive private investment, highlighting the significant role of risk transfer to the private partner. These findings show both complementary and substitution effects with other influencing factors.

Renewable Energies: Essential Tools to Combat Global Warming

The study highlights the severe impact of fossil fuel burning on global warming, especially in developing countries due to their geographical and economic vulnerabilities. Renewable energies are promoted as essential tools to combat global warming and transition to a low-carbon economy, aligning with the United Nations' Sustainable Development Goals (SDGs). Public-private partnerships (PPPs) are seen as effective mechanisms for promoting renewable energy in developing countries, pooling resources, and creating synergies between public authorities and private companies.

Factors Influencing Private Investment in Renewable Energy Projects

The literature review delves into the impact of risk allocation strategies on private investment, identifying various risk sources such as bounded rationality, external environment, and opportunistic behavior. It categorizes risks into macro, meso, and micro levels, suggesting that meso risks should be primarily managed by the private sector for efficiency. The study employs different proxies to measure the level of risk transferred to the private sector, revealing that higher risk transfer correlates with increased private investment. Other project characteristics, such as the contract award method, participation of local partners, government support programs, and the involvement of development institutions, also significantly impact private investment.

The research formulates several hypotheses to explore these factors, proposing that direct negotiation methods, local partner participation, government support, development institutions' backing, and unsolicited proposals positively relate to the volume of private investment. To approach these hypotheses, the study uses a variety of proxies and dummy variables to measure the impact of these factors. It employs generalized linear models (GLM) with multilevel fixed effects to analyze the data, controlling for country-specific differences.

Empirical Findings: Key Drivers of Private Investment

The empirical findings confirm that projects with higher risk transfer to the private sector attract more private investment, supporting the main hypothesis. The results also validate the positive impact of direct negotiation methods, local partner participation, government support programs, and development institutions' backing on private investment. Furthermore, the study explores the interaction effects between risk transfer and other factors, finding both complementary and substitution effects.

For instance, bundling responsibilities in the private partner alleviates opportunistic behaviors, such as underinvesting during the construction phase, which would jeopardize the private contractor's interests during the operation phase. The temporary allocation of greater property rights to the private contractor in PPP types where the private partner takes on more responsibilities broadens the scope for efficiency gains. This makes the project more attractive to private investors due to greater possibilities for business and better control over project assets.

Other significant findings include the positive impact of having local partners in the project, which helps alleviate the uncertainties faced by foreign private contractors due to their unfamiliarity with the local economic and institutional environment. Government support programs, both direct and indirect, are crucial as they reduce uncertainties and transaction costs, making projects more attractive to private investors. Development institutions like multilateral development banks (MDBs) provide crucial financial and technical support, reducing the perceived risk for private contractors and acting as catalysts for private investment.

Additionally, unsolicited proposals, where the initiative for the project comes from the private sector, are shown to attract more private investment. These proposals often bring innovation and creativity to PPPs, especially in developing countries with limited public sector capacity. The study also highlights the importance of a sound economic environment, institutional stability, and a friendly environment for renewable energies in attracting private investment.

Practical Implications for Policymakers and Investors

The conclusion emphasizes the practical implications of these findings for policymakers, private investors, and project managers. Understanding the impact and interaction of various factors on private investment can guide stakeholders in optimizing risk allocation practices to enhance the effectiveness and sustainability of renewable energy projects. The study contributes to the academic literature on PPPs in renewable energies and provides valuable insights for promoting private investment in developing countries, offering a roadmap for better collaboration between public and private sectors to achieve sustainable development goals.
