Nigeria’s Power Sector: The Big Picture

Nigeria stands at a critical juncture in its economic development, yet a fundamental challenge continues to undermine every sector of the economy: the inadequate and unreliable supply of electricity. As Adetayo Adegbemle, Executive Director of PowerUp Nigeria, a consumer rights and power sector policy advocacy organisation, has persistently highlighted, the electricity sector represents far more than a utilities problem—it is the backbone upon which Nigeria’s industrial renaissance must be built. The power sector crisis has become synonymous with Nigeria’s broader economic struggles, particularly for the manufacturing sector, which once served as a pillar of growth and employment.

The statistics paint a sobering picture of Nigeria’s manufacturing landscape. Over 60 per cent of manufacturing firms have exited the national grid, representing an unprecedented abandonment of critical infrastructure by the very enterprises that should be anchoring economic growth. This mass exodus is not a sudden development but the culmination of years of frustration, mounting costs, and deteriorating grid reliability. What was meant to be an engine of development has become a liability that manufacturers can no longer afford to ignore.

The financial burden imposed by an unreliable power supply has become staggering. Manufacturers spent N676.6 billion on alternative energy in the first half of 2025, a figure that barely decreased from the N708.1 billion spent in the second half of 2024. This represents an extraordinary annual outflow of resources dedicated solely to generating electricity that should have been provided by the national grid. More disturbingly, despite this expenditure, manufacturers could not meet their power needs due to the country’s unreliable and unaffordable electricity supply. The paradox is stark: manufacturers are spending billions on generators while still operating below capacity and unable to reliably serve their customers.

The true cost of Nigeria’s power crisis extends far beyond generator expenses. The lack of electricity supply has hampered business growth in the manufacturing sector, leading to yearly economic losses estimated at $26.2 billion (N10.1 trillion), equivalent to about 2 per cent of World GDP. To contextualise this figure, this annual loss is equivalent to the entire budget allocation for Nigeria’s health sector in recent years. It represents resources that could be invested in education, infrastructure, healthcare, or poverty reduction—instead, they are squandered on compensating for the state’s failure to provide basic services.

The African Development Bank’s assessment is equally damning: power outages cost Nigerian businesses about three per cent of their annual sales, with more than 70 per cent of firms relying on generators because of the country’s unreliable electricity supply. This three percent loss, when aggregated across Nigeria’s entire business landscape, translates into hundreds of billions of naira that could have supported growth, employment, and poverty reduction.

Understanding why power supply is so critical to manufacturing requires examining the sector’s cost structure. The manufacturing sub-sector in Nigeria spend on average 90% of its variable cost on infrastructure, with electric power accounting for half of the amount. This means that electricity costs represent approximately 45% of a typical manufacturer’s variable costs—a burden that no other competitor in more developed nations faces to such an extent. When grid electricity becomes unreliable, manufacturers are forced to operate their own generation facilities, effectively doubling their power costs while simultaneously reducing their competitiveness in both local and international markets.

I have noted that manufacturers spend several billion dollars annually on alternative energy sources, an expense they in turn push to consumers. This cost pass-through is inevitable, leading to higher prices for consumer goods and services, which ultimately dampens demand and slows economic growth. The cycle becomes self-reinforcing: high manufacturing costs lead to high consumer prices, reducing purchasing power and demand, which in turn leads to underutilization of manufacturing capacity and job losses.

The consequences for employment have been severe. The manufacturing sector recorded 18,935 job losses in the first six months of 2025, a direct consequence of firms reducing operations, relocating, or exiting the grid entirely. These are not merely statistics; they represent families losing income, communities losing their economic anchors, and skilled workers being forced into informal sectors or unemployment.

The employment crisis extends beyond direct manufacturing jobs. When large industrial consumers exit the grid, they also reduce demand for supporting services—transportation, logistics, packaging, and raw material processing. The multiplier effect of manufacturing decline ripples through the entire economy, destroying livelihoods and reducing the tax base that governments rely upon to fund essential services.

The gap between installed capacity and actual generation capacity reveals the fundamental problem. Nigeria’s average generation capacity increased marginally by 12.59 percent to 4,633.79 MW in 2025 against 4,050.07 MW recorded five years ago (2020), representing modest progress. However, this progress masks deeper structural issues. Nigeria’s power sector achieved a 35 per cent improvement in capacity, generation, transmission, and distribution in 2024, yet generation increased by about 600MW in one year, indicating that progress has stalled or plateaued.

More critically, the national grid was reported to have collapsed at least 11 times by November 2024, primarily due to deteriorating infrastructure. Each grid collapse represents a cascading crisis for manufacturers—production halts, goods spoil, contracts are breached, and trust in the system erodes further. This unreliability makes long-term business planning impossible and deters foreign and domestic investment.

I have called for the Federal Government to bring back exited industries and organisations to the national grid to help stabilise electricity supply and reduce costs of goods. This perspective recognises that the solution is not merely to generate more electricity but to create an ecosystem where large industrial consumers find it economically attractive to reconnect to the grid. This requires tariff stability, guaranteed supply reliability, and transparent regulatory frameworks—areas where Adegbemle has noted that the power sector is “adrift” and “lacks policy direction”.

The government has taken some steps toward reform. Power sector revenue grew by 70 per cent, from N1.05 trillion to about N1.7 trillion in 2024, indicating improved collections and tariff implementation. However, these gains remain modest relative to the scale of the challenge. The Federal Government’s release of a National Integrated Electricity Policy represents a belated acknowledgement that structural reform is necessary, but execution remains the critical test.

The fundamental truth is that Nigeria cannot achieve the manufacturing-led economic growth necessary to lift millions out of poverty without solving its power sector crisis. If large-scale consumers return to the grid and large manufacturers spend their billions on the national grid instead of generators, the government could easily provide electricity at significantly reduced costs to all consumers. This observation captures the essence of the solution: a functioning power sector creates virtuous cycles of growth, while a broken one creates vicious cycles of decline.

The challenge is not merely technical—Nigeria has the resources, both financial and natural, to generate abundant electricity. The challenge is governance, regulatory consistency, and the political will to prioritise long-term structural development over short-term political considerations. Until Nigeria’s policymakers and regulatory authorities demonstrate commitment to creating a reliable, affordable, and transparent power system, the manufacturing sector will continue to decline, economic growth will remain constrained, and millions of Nigerians will continue to bear the cost of a failed system.

As my advocacy through PowerUp Nigeria underscores, the power sector is not a technical problem awaiting an engineering solution—it is a development challenge requiring sustained policy commitment, transparent implementation, and unwavering focus on the ultimate goal: using electricity as a tool to unlock Nigeria’s vast productive potential and transform millions of lives. Until that commitment materialises, Nigeria’s economy will continue to operate far below its potential, constrained by the very infrastructure that should be setting it free.
