Energy Access Financing

Electrifying the 750 million people who lack electricity access would cost roughly $30-40 billion per year for a decade. For context, the world spends $2.8 trillion per year on energy. The cost of universal energy access is a rounding error in global energy spending. The problem is not affordability at the global level; it is getting capital to where it is needed.

The financing gap has three layers. Country risk: the nations with the worst energy access (DRC, Chad, Niger, South Sudan) have the highest sovereign risk ratings, making private capital prohibitively expensive. Project scale: electrifying rural villages requires thousands of small projects ($50,000-500,000 each), not a few large ones that institutional investors prefer. Revenue uncertainty: households earning $1-2/day can pay very little for electricity, making cost recovery uncertain without subsidies.

Mini-grids as the emerging model. For the 500+ million people too remote for grid extension, solar mini-grids (50-500 kW serving 500-5,000 customers) are increasingly cost-effective. Companies like Husk Power and PowerGen deploy mini-grids across sub-Saharan Africa at $0.30-0.50/kWh, roughly competitive with diesel generators. But financing a portfolio of hundreds of mini-grids requires aggregation structures that bundle small projects into investment-grade packages.

Why hasn't the private sector solved this?

Because the combination of high risk, small scale, and low revenue per customer makes returns unattractive relative to alternatives. Private investors can earn 8-12% deploying solar in Texas with virtually no country risk. Earning 5% deploying mini-grids in Niger requires navigating political instability, currency risk, and regulatory uncertainty. Blended finance (public money absorbing first losses to make private returns acceptable) is the standard prescription, but it has not scaled to meet the need.
