Why private capital alone is not enough
Africa has world-class solar resources, yet deployment is far too slow to meet either climate or energy-access goals. The reason is financial, not technical. The IEA finds that private finance still accounts for less than 30% of electricity-access funding in these regions — leaving a gap that public money alone cannot fill.[5]
The shortfall is not a temporary market failure but a structural one. Investors price the risk of these markets as systemic rather than project-specific: it is the country and currency environment they fear, not the individual solar power plant. That logic produces four recurring barriers:
Barrier | Why it blocks private investment |
The ‘Affordability Gap’ | Most people without power live in extreme poverty. Private firms cannot set prices high enough to recover their investment without making the service unaffordable for the very customers they are meant to serve. |
Currency Incompatibility | Investors bring in ‘hard’ currency (USD or EUR) to build projects but earn revenue in local ‘soft’ currency. If that currency crashes — common in volatile economies — the value of the investment evaporates instantly. |
High Transaction Costs | Due diligence, legal fees and supply chains for a small solar project in a remote area can cost almost as much as for a massive wind farm in Europe — making small-scale development inefficient for large equity firms. |
Off-taker Risk | In centralised systems, the ‘off-taker’ buying the power is usually a state-owned utility. Many are deeply indebted or technically insolvent, so private generators fear they will never be paid for the electricity they produce. |
The structural problem
Development finance institutions (DFIs) have tried to close these gaps with guarantees and concessional finance — using concessional money to de-risk private capital. In practice this has largely failed to mobilise investment at the scale required.
So why does the sector keep pushing private capital? Public debt. Borrowing in low-electrification countries has reached record highs, and most of these governments simply lack the fiscal space to take on more debt to build state-owned grids. Private capital is necessary because the public alternative looks unaffordable.
Private capital has not unlocked development where electrification rates are low — and the barriers are structural, not incidental. With under 30% of access finance coming from private sources and concessional finance falling short, the gap will not close with private capital alone.
