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. I have persistently highlighted that 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. More than 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 unreliable power supply has become staggering. Manufacturers spent N676.6 billion on alternative energy in the first half of 2025, only slightly lower than the N708.1 billion spent in the second half of 2024. This represents an extraordinary outflow of resources dedicated solely to generating electricity that should have been provided by the national grid. More disturbingly, despite this expenditure, manufacturers have still been unable to meet their power needs because of the country’s unreliable and unaffordable electricity supply. The paradox is stark: manufacturers are spending billions on generators while still operating below capacity and struggling to reliably serve their customers. The true cost of Nigeria’s power crisis extends far beyond generator expenses. The lack of reliable electricity supply has hampered business growth in the manufacturing sector, leading to annual economic losses estimated at $26.2 billion (N10.1 trillion). To put this figure into perspective, it is comparable to the annual GDP of several African economies and exceeds the budgets of key sectors of government. These are resources that could otherwise be invested in education, infrastructure, healthcare, or poverty reduction. Instead, they are lost to inefficiencies arising from the failure to provide reliable electricity. The African Development Bank’s assessment is equally damning: power outages cost Nigerian businesses approximately three per cent of their annual sales, while more than 70 per cent of firms rely on generators because of the country’s unreliable electricity supply. This three per cent loss, when aggregated across the economy, translates into hundreds of billions of naira that could otherwise support growth, employment, and poverty reduction. Understanding why power supply is so critical to manufacturing requires an examination of the sector’s cost structure. Manufacturing firms in Nigeria spend, on average, 90 per cent of their variable costs on infrastructure, with electric power accounting for roughly half of that amount. This means that electricity costs represent approximately 45 per cent of a typical manufacturer’s variable costs—a burden that few competitors in more developed economies face. When grid electricity becomes unreliable, manufacturers are forced to operate their own generation facilities, effectively increasing their energy costs while simultaneously reducing their competitiveness in both local and international markets. I have noted that manufacturers spend several billions of dollars annually on alternative energy sources, costs that are inevitably passed on to consumers. This cost transfer leads to higher prices for goods and services, dampening consumer demand and slowing economic growth. The cycle becomes self-reinforcing: high manufacturing costs lead to higher consumer prices, reducing purchasing power and demand, which in turn results in underutilised production 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 disconnecting from the grid entirely. These are not merely statistics; they represent families losing income, communities losing economic anchors, and skilled workers being pushed into unemployment or the informal economy. The employment crisis extends beyond direct manufacturing jobs. When large industrial consumers exit the grid, they also reduce demand for supporting services such as transportation, logistics, packaging, and raw-material processing. The multiplier effect of manufacturing decline ripples throughout the economy, destroying livelihoods and reducing the tax base upon which governments depend to fund essential services. The gap between installed capacity and actual generation reveals the fundamental problem. Nigeria’s average generation capacity increased marginally by 12.59 per cent, rising to 4,633.79 MW in 2025 from 4,050.07 MW in 2020. While this represents progress, it masks deeper structural deficiencies. The power sector reportedly achieved a 35 per cent improvement in generation, transmission, and distribution performance in 2024, yet actual generation increased by only about 600 MW, suggesting that progress has stalled or plateaued. More critically, the national grid reportedly collapsed at least 11 times by November 2024, largely due to deteriorating infrastructure. Each collapse triggers a cascading crisis for manufacturers: production halts, goods spoil, contractual obligations are breached, and confidence in the system erodes further. Such unreliability makes long-term business planning difficult and discourages both domestic and foreign investment. I have consistently called on the Federal Government to create conditions that encourage industries and organisations that have exited the grid to reconnect. This would help stabilise electricity supply while reducing production costs and, ultimately, the prices of goods and services. The solution is not merely to generate more electricity but to create an ecosystem in which large industrial consumers find it economically attractive to return to the grid. This requires tariff stability, guaranteed supply reliability, and transparent regulatory frameworks. As I have previously noted, the sector remains adrift and lacks a clear policy direction. The government has taken some steps toward reform. Power sector revenue grew by 70 per cent, from N1.05 trillion to approximately N1.7 trillion in 2024, reflecting improved collections and tariff implementation. However, these gains remain modest relative to the scale of the challenge. The Federal Government’s release of the National Integrated Electricity Policy represents a welcome acknowledgment that structural reform is necessary, but implementation remains the ultimate test. The fundamental truth is that Nigeria cannot achieve the manufacturing-led growth required to lift millions out of poverty without resolving its power sector crisis. If large-scale consumers return to the grid and manufacturers channel their billions of naira in energy spending through the national electricity system rather than private generators, the government could provide electricity at significantly lower costs to all consumers. This observation captures the essence of the solution: a functional power sector creates virtuous cycles of growth, while a dysfunctional one creates vicious cycles of decline. The challenge is not merely technical. Nigeria possesses the financial and natural resources necessary to generate abundant electricity. The real challenge lies in governance, regulatory consistency, and the political will to prioritise long-term structural development over short-term political considerations. Until policymakers and regulatory authorities demonstrate a sustained commitment to creating a reliable, affordable, and transparent power system, the manufacturing sector will continue to struggle, economic growth will remain constrained, and millions of Nigerians will continue to bear the cost of systemic failure. As my advocacy through PowerUp Nigeria underscores, the power sector is not simply 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 catalyst 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.
