Africa has some of the world’s best solar resources, yet it remains one of the most expensive places to finance utility-scale renewable energy. The reason is not the cost of solar panels. It is the cost of capital. Across the continent, developers are bringing increasingly competitive projects to market, while governments continue to improve procurement frameworks and utilities sign long-term power purchase agreements. Yet many projects still struggle to reach financial close because lenders apply a significant risk premium to African markets. This is what the industry calls the Africa Premium.
International lenders price more than engineering risk. They also price sovereign credit, currency volatility, utility payment performance, political stability, and contract enforcement. Those risks translate directly into higher interest rates. As financing costs rise, the cost of electricity rises alongside them. Projects that appear commercially attractive on paper become difficult to finance, even when the underlying solar resource is exceptional. The result is a market where Africa often pays more to finance clean energy than regions with far weaker renewable resources.
High borrowing costs remain one of the biggest obstacles to scaling renewable energy. Weak utility balance sheets, transmission constraints, lengthy procurement processes, and expensive debt combine to slow project development and push tariffs higher than they need to be. This is why reducing the cost of capital has become just as important as improving technology.
The solution is allocating risk more intelligently. Institutions such as the African Development Bank (AfDB) and the Multilateral Investment Guarantee Agency (MIGA) help lower financing costs by providing guarantees, blended finance, political risk insurance, and project preparation support.

These instruments improve confidence among commercial lenders by protecting against the risks private markets are least willing to absorb. When lenders perceive lower risk, they require lower returns. That translates into cheaper debt, more competitive tariffs, and projects that are more likely to reach financial close.
MIGA focuses primarily on political and sovereign risk, offering protection against events such as expropriation, breach of contract, and currency transfer restrictions. AfDB takes a broader approach by combining concessional finance, guarantees, project preparation, and risk-sharing facilities to improve overall project bankability. Their methods differ. Their objective is the same. Reduce financing risk enough to attract private capital.
Africa’s energy transition is constrained by the price investors place on financing them. Until the cost of capital falls, the continent will continue to pay more for clean energy than its resource base justifies. Reducing the Africa Premium is one of the most important energy policy challenges on the continent.
