Nigeria can build solar power plants, but funding remains elusive

The electricity crisis in Nigeria isn’t a technical glitch; it’s a financing one. In 2024, only 62.5 % of Nigerians had power, leaving 80 million people living in darkness or paying a fortune for diesel generators. The Nigeria Electrification Project (NEP) proved that solar mini‑grids can light up homes, but the real battle is securing the capital to scale those systems across the country.

The NEP’s first wave of 180 solar hybrid mini‑grids spanned 23 states, powering 146 000 households and adding 19.2 MW of renewable capacity. These deployments show that distributed renewable energy works in Nigeria’s varied climates and remote regions. Yet the project’s success is not a blueprint; it is a cautionary tale. Developers received a $350 grant per connection to offset equipment costs. As the naira weakened, the World Bank bumped the subsidy to $600 to cover foreign‑exchange losses, but the total pool shrank from $150 million to $56.7 million. When the subsidy was recalibrated to $450, fewer connections followed, proving that grant‑only models cannot keep pace with currency volatility and rising import prices.

Solar panels, inverters, and batteries are bought abroad, priced in dollars. Revenues, however, come in naira. When the naira slides, the cost of a single panel can rise by 20 %. Developers, who already operate on thin margins, find themselves drowning in foreign‑exchange risk. The NEP’s experience exposes a systemic mismatch: foreign‑currency debt, local‑currency income, and a subsidy that cannot fully compensate for the exchange rate swings. This mismatch is not a one‑off issue; it is a structural flaw that will repeat with every new mini‑grid developer.

Hakeem Disu of Lihon Energy admits that traditional bank lending is ill‑suited for mini‑grids. Short loan tenors and high interest rates leave little room for the long‑term, low‑margin business model that renewable developers rely on. Commercial credit remains a wall, not a bridge, for the sector. The result? Many entrepreneurs who could deliver clean power are forced to abandon projects or rely on precarious grant funding that is already stretched thin.

The 2024 Residential Energy Demand‑Side Survey shows households spent ₦327.05 billion ($246.3 million) on petrol and diesel generators, versus ₦175.05 billion ($131.8 million) on grid electricity. This misallocation represents a massive, untapped pool of capital that could be redirected toward renewable infrastructure. If the government could channel even a fraction of that spending into solar mini‑grids, the gap between projected demand and supply would shrink dramatically.

I predict that by 2028, Nigeria will see the first wave of structured finance productsblended finance, green bonds, and risk‑sharing mechanismstailored specifically for mini‑grid developers. These instruments will hedge currency risk, extend loan tenors, and provide the capital depth that grants cannot. The government’s role will shift from direct subsidies to creating a favorable regulatory environment that attracts private capital.

Everyone celebrates the NEP’s success, but that celebration masks a deeper problem: the model is unsustainable. The focus on grants ignores the fact that the real cost of a mini‑grid is in dollars. Without a mechanism to lock in exchange rates or provide long‑term financing, the sector will stall. The narrative that “solar can solve the power crisis” is incomplete unless it includes a financing strategy that matches the scale of the need.

The Nigerian government must act now. A dedicated renewable energy fund, backed by international investors and structured to mitigate currency risk, could unlock the commercial capital needed. Only then can the 80 million unserved households transition from diesel to clean, reliable power.

Nigeria’s solar potential is clear; its funding model is not. The next decade will decide whether the country turns the light on for all or keeps the dark alive.
