A new analysis highlights a persistent mismatch in renewable energy financing across African markets, where growing climate finance commitments are not translating into bankable projects on the ground.
The study finds that structural weaknesses in global financial systems are a key barrier. These include outdated credit rating frameworks that cap project ratings under the “sovereign ceiling,” meaning even well-structured solar and wind projects are rated no higher than the country in which they operate. This increases borrowing costs and limits access to long-term capital, despite many projects having secured revenues through long-term power purchase agreements.
It also points to a heavy reliance on short-term lending cycles, with average loan tenors in emerging markets falling to as low as five years, compared to infrastructure lifespans of 20 to 30 years. This creates refinancing risks that can significantly raise costs over time and, in some cases, threaten project viability if market conditions tighten or interest rates rise.
The analysis further notes that existing guarantee and blended finance instruments are often too complex or narrowly designed, limiting their effectiveness in de-risking investments. It concludes that without reform in credit rating practices, debt structuring, and development finance tools, a significant portion of Africa’s renewable energy potential will remain underfunded despite strong policy momentum for clean energy expansion.
