The current landscape of decentralised renewable energy (DRE) projects is marked by significant technological advancements and a robust push towards sustainable energy solutions. As nations grapple with the urgent need to combat climate change and reduce reliance on fossil fuels, DRE technologies have emerged as pivotal players in the global energy transition. Innovations in solar, wind, and energy storage are driving the sector forward, while hybrid microgrids and smart storage solutions are enhancing the viability and efficiency of decentralised systems. Concurrently, supportive government policies and increased corporate investments are catalysing the growth of DRE projects, making them a cornerstone of future energy infrastructure.
DRE technologies, therefore, play a crucial role in enabling equitable energy transitions and ensuring energy security for many emerging and developing economies. These technologies address pressing challenges faced by developing countries, including supporting diverse energy needs, reaching last-mile communities, and meeting rising energy demands in a climate-responsible manner.
The potential market for clean energy technologies is substantial, with estimates of US$53 billion in India and US$11 billion across Africa. Additionally, the DRE sector is projected to create significant employment opportunities, with 89,000 jobs in India and 58,000 in Kenya by 2023. However, realising this potential requires substantial financial investment. It is estimated that an annual investment of US$45 billion is necessary to achieve Sustainable Development Goal 7, access to clean and affordable energy, by 2030.
Challenges facing decentralised energy projects
Such a dynamic environment presents both challenges and opportunities, underscoring the critical need for scalable development finance to unlock the full potential of decentralised energy solutions.
The primary hurdle is the substantial upfront costs associated with purchasing and installing solar panels, inverters, mounting systems, and other equipment. This initial financial burden often deters potential investors and project developers. Furthermore, financiers are often sceptical about funding entrepreneurs basing their businesses on customised DRE solutions, particularly in emerging markets. This hesitancy stems from perceived risks associated with new technologies, uncertain market demand, and the lack of established track records for many DRE projects.
The financing landscape is further complicated by the diverse needs of different stakeholders. Large corporates, micro-, small and medium-sized enterprises (MSMEs), and households each require specific policy interventions and tailored financing solutions. For instance, while large corporates may have access to long-term financing, they struggle with high costs due to policy, offtake, and technology risks. Additionally, there is a notable gap in the availability of long-term, low-cost financing options. The domestic green bond market, particularly for issuances beyond ten years, remains underdeveloped. This shortage of patient capital hampers the growth of DRE projects, which often require extended periods to achieve profitability.
Strategies to overcome financing barriers
To scale development finance and increase capital flows to decentralised energy projects, a multi-faceted approach is necessary. This can be achieved through:
- Innovative financing models: Power Purchase Agreements (PPAs) are essential for financing decentralized energy projects by providing stable revenue streams and attracting investors. In the U.S., corporations like Amazon use PPAs to meet sustainability goals and lock in energy prices. Europe sees the rise of virtual PPAs for flexibility across borders. Africa employs take-or-pay PPAs for solar projects, ensuring payment even without off-take, as seen in Senegal. Despite challenges, standardizing contracts and integrating risk mitigation enhance PPA appeal, driving global renewable energy adoption
- Blended finance: It combines debt, equity, and grants to reduce risks and enhance returns, making projects more attractive to private investors. An example is CrossBoundary Energy Access, which uses this approach to fund solar-powered mini-grids in Africa, blending philanthropic and commercial capital to de-risk the project and attract private funding. Benefits include risk mitigation, scalability, and inclusivity, though challenges like stakeholder coordination and tailored financial instruments persist. Effective governance and capacity-building can address these issues
- Green bonds and sustainability-linked loans: Green bonds and sustainability-linked loans (SLLs) are vital for financing decentralized energy projects by mobilizing long-term capital. Green bonds have surged in popularity, growing from $246 billion in 2017 to $4.3 trillion by 2024, driven by investor demand for sustainable investments. Key strategies for their effectiveness include strong disclosure standards, credible ESG strategies, and regulatory support. SLLs incentivize borrowers to meet sustainability targets with financial benefits like reduced interest rates
- Risk mitigation instruments: Risk mitigation instruments are vital for making decentralized renewable energy (DRE) projects more attractive to investors by addressing political, regulatory, currency, and technology risks. Political risk insurance, such as that provided by MIGA, protects against expropriation and currency inconvertibility. Currency risk hedging tools like those from TCX Fund manage exchange rate volatility. Partial credit guarantees, exemplified by the African Development Bank, enhance project creditworthiness. Liquidity facilities, like IRENA’s Africa Clean Energy Facility, ensure payment continuity. While effective, these instruments face challenges like complexity and limited availability, necessitating cost reduction and capacity building for broader adoption
- Carbon finance integration: Leveraging carbon credits enhances the viability of decentralized renewable energy (DRE) projects by providing additional revenue streams, attracting investment, and improving project economics. In China, the national Emissions Trading System (ETS) supports large-scale solar and wind projects, generating carbon credits sold domestically and internationally. In India, carbon credits from solar home systems and mini grids aid rural electrification. Africa benefits from community-based projects like clean cookstove initiatives, generating credits to subsidize costs. Despite challenges like market volatility and regulatory uncertainty, carbon finance significantly supports sustainable energy development globally
- Tailored solutions for different stakeholders: Tailored financing solutions are essential for advancing decentralized renewable energy (DRE) projects across various stakeholders. Large corporations leverage green bonds and corporate PPAs to fund substantial renewable energy initiatives, as seen with Apple and Google in Europe. MSMEs benefit from leasing models and energy-as-a-service (EaaS) options, reducing upfront costs and financial risks, exemplified by SIDBI in India and Calibrant Energy in Southeast Asia. These customized financing models help drive global renewable energy adoption and sustainability
- Government support and policy framework: India, Germany, the United States, Japan, and Australia have implemented various policies to support renewable energy. India promotes solar energy through schemes like PM-KUSUM, providing financial aid to farmers. The U.S. employs tax incentives, grants, and loan guarantees to drive solar and wind investments. Australia’s Renewable Energy Target scheme issues tradable certificates to renewable producers. These diverse strategies demonstrate the importance of supportive policies and incentives in advancing renewable energy projects globally
- Capacity building and standardisation: Investing in capacity building for local financial institutions and standardizing project assessment methodologies are key to enhancing investment in decentralized energy projects. Capacity building, exemplified by IRENA’s Africa Clean Energy Corridor, trains local banks to evaluate better and finance renewable energy projects, reducing transaction costs and boosting investor confidence. Standardizing methodologies, like the Climate Bonds Standard, ensures consistent project evaluations, making investments more attractive. Regional collaborations, such as the APEC Energy Working Group, and national initiatives, like India’s National Institute of Solar Energy (NISE), further support these efforts by sharing best practices and providing targeted training. These strategies collectively foster a robust financing ecosystem for sustainable energy development
By implementing these solutions, we can address the financing challenges facing DRE projects and unlock the sector’s full potential. This approach will not only drive the transition to clean energy but also support economic development and job creation in emerging markets. As the world moves towards a sustainable future, scaling development finance for decentralised energy projects will play a crucial role in achieving global climate goals and ensuring equitable access to clean energy.
