Developing Country Finance

Solar panels cost the same in Lagos as in London. The financing does not. A solar project in Nigeria might pay 12-15% interest on capital. The same project in Germany pays 3-5%. Since solar is almost entirely a capital cost (fuel is free), the cost of capital is the cost of energy. This single factor can double the price of clean electricity in the countries that need it most.

The transition investment gap shows that emerging markets need roughly $1 trillion per year in clean energy investment but receive about $300 billion. The gap is not primarily about technology availability. It is about risk premiums. Investors demand higher returns in countries with currency volatility, weak contract enforcement, political instability, or sovereign default risk. These premiums make projects that are bankable in rich countries unbankable in poor ones.

The cost-of-capital multiplier. A 100 MW solar plant costs $80 million to build anywhere. At 4% financing (Germany), the levelized cost is roughly $35/MWh. At 12% financing (Nigeria), the same plant produces power at roughly $70/MWh.

Can development banks close this gap?

Partially. Multilateral development banks (World Bank, African Development Bank) offer concessional loans at below-market rates and provide guarantees that reduce private investor risk. But their total lending capacity is roughly $100 billion per year across all sectors, a fraction of what is needed. Closing the gap requires "blended finance" structures where public money absorbs the riskiest portion, making the rest attractive to private capital.
