Does Nigeria need a $100 billion investment in the power sector?

The Minister of Power recently declared that Nigeria requires over $100 billion in public and private investment across generation, transmission, and distribution to deliver reliable electricity. The figure is staggering. But is capital really the binding constraint?

The privatisation of 2013, selling generation and distribution assets to private operators, was supposed to unlock efficiency; however, this target has not been met. Successive administrations have injected over N10 trillion in direct interventions, subsidies, and bailouts, including the Central Bank, which had deployed approximately N2.3 trillion in power sector interventions by 2023. A N501 billion bond was fully subscribed in early 2026 to clear GenCos’ debt. President Tinubu recently approved an additional N3.3 trillion in legacy debt settlement in April 2026. International partners have added more than $2 billion through World Bank programmes.

Yet the results remain weak. According to Nigerian Electricity Regulatory Commission data, the grid has collapsed 105 times in the decade since privatisation, 93 collapses under the previous administration and at least 12 within the first sixteen months of the current administration. Installed capacity stands at roughly 13,625 MW, yet only about 4,500 MW is distributed daily. Meanwhile, 90 million Nigerians resort to generators, spending nearly $22 billion annually on fuel, which is more than the cost of fixing the grid several times over.

The sector’s liquidity crisis has deepened into a debt trap of approximately N6.6 trillion. Generation companies cannot pay for gas because distribution companies cannot collect adequately from customers. Until this circular debt is resolved, new investment will flow straight into the same trap.

Egypt offers an instructive comparison. It added 28,229 MW of capacity in just three years (2015–2018), reaching approximately 55 GW. South Africa, despite its struggles, entered 2026 with an additional 4,400 MW of available capacity, pushing its energy availability factor above 64 per cent.

For Nigeria’s estimated 240 million citizens to reach South Africa’s current per-capita generation levels (approximately 692 MW per million people), the country would need roughly 166,000 MW of installed capacity, more than 12 times its current 13,625 MW. At current capital costs of $1.5–2 million per MW for gas generation, the generation component alone would demand between $100 billion and $200 billion. This excludes transmission and distribution. The $100 billion figure, therefore, is not an overestimate. It may be a minimum down payment, but only if deployed effectively.

The challenge is not insufficient funding. It is how the money is spent. The Gbarain and Mambilla power plants remain uncompleted after decades of expenditure. Hundreds of transmission projects funded since 2007 remain incomplete. The most critical obstacle is the debt trap. The N6.6 trillion circular debt means new investment is immediately absorbed by outstanding obligations rather than new infrastructure.

Equally problematic is the political economy of tariffs. Cost-reflective tariffs have been impossible to implement for two decades because labour unions and political opponents block every increase. Without a mechanism to insulate tariff-setting from electoral cycles, private capital will remain wary.

Nigeria has committed to net-zero carbon emissions by 2060. The Energy Transition Plan estimates cumulative investment needs of $410–500 billion above business-as-usual by 2060, requiring a leap to 277 GW of installed capacity with heavy renewable penetration. The proposed $100 billion, therefore, represents not the full transition cost but a critical down payment on a much larger, decades-long effort.

This is urgently important because global oil demand is projected to decline. With oil accounting for 90 per cent of export earnings and 50 per cent of government revenue, Nigeria faces a future where fossil fuel dependence becomes an economic liability.

Nigeria’s solar irradiation averages 5.5 kWh/m²/day, one of the highest in the world. Decentralised solar mini-grids could unlock growth and create jobs. The resource is abundant. What is missing is the institutional framework to deploy it.

The $16–17 billion in foreign investment that flowed into Nigeria’s energy sector in 2024, reported by NNPC officials at CERAWeek 2025, proves that capital is available when the regulatory environment is clear. The Electricity Act 2023, which grants states authority to regulate their power markets, is a promising start.

Does Nigeria need $100 billion in power sector investment? Yes, but only if accompanied by fundamental reform. First, the N6.6 trillion circular debt must be cleared through a transparent, one-time settlement. Second, establish credible, independent tariff regulation. An independent regulator with fixed multi-year review cycles and a transparent subsidy mechanism for poor households is essential. Third, complete abandoned infrastructure, a $100 billion investment, might simply replicate the failures of the billions already spent.

The global energy transition is not waiting. The oil revenues that sustain this country are not guaranteed forever. The window for action is closing. The implication is clear: future electricity demand will rise significantly. Meeting both current deficits and future needs will require not just expansion but transformation. This means investing in cleaner generation sources such as solar and gas-to-power, upgrading grid infrastructure to handle variable energy inputs, and deploying distributed energy solutions such as mini-grids to complement the national grid. The cost of achieving this transition will likely exceed $100 billion over time.
