Nigeria has once again emerged as the country with the largest number of people living without access to electricity, a distinction no government wants to hold. According to the World Bank’s latest energy access data, around 86.8 million Nigerians still lack electricity, the highest figure globally despite years of investment and reforms in the power sector.
Globally, nearly 92% of the world’s population now has access to electricity, yet more than 666 million people remain without power, with Sub-Saharan Africa accounting for the overwhelming majority of that deficit.
The headline is alarming, but the deeper issue is what this means for Nigeria’s economic future.
Conversations about electricity often focus on households sitting in darkness, but unreliable power affects far more than daily convenience. Every factory relying on diesel generators produces goods at a higher cost. Every small business spends more on fuel than expansion.
Every hospital, school and technology startup faces operating costs that competitors in other countries simply don’t have to bear. Electricity is no longer just a utility. It is economic infrastructure.
Nigeria’s economy has continued to grow in sectors such as fintech, digital services and manufacturing, yet many of those industries are forced to create their own power solutions.
Estimates suggest businesses spend billions of naira annually running generators, costs that are ultimately passed on to consumers through higher prices. That makes Nigerian products less competitive while discouraging investment from companies looking for predictable operating environments.
The irony is that Nigeria is not a country lacking energy resources. It possesses some of Africa’s largest natural gas reserves, abundant sunshine suitable for solar generation and significant hydroelectric potential.
The challenge has consistently been converting those resources into reliable electricity that reaches homes and businesses. Transmission bottlenecks, aging infrastructure, distribution losses, vandalism and policy inconsistencies have all contributed to a system that struggles to meet demand.
The ranking also exposes a growing development gap.
Countries with reliable electricity tend to attract more manufacturing, create more industrial jobs and build stronger digital economies. Nations that fail to expand access risk falling behind even if they record positive GDP growth. Reliable electricity influences everything from education outcomes to healthcare delivery and investor confidence.
There are reasons for cautious optimism. The federal government has expanded rural electrification programmes, private investment in solar energy has increased, and initiatives such as Mission 300 aim to accelerate electricity access across Africa. Still, progress in Nigeria has remained slower than required to significantly reduce the country’s deficit compared with peers.
Until Nigeria significantly improves electricity access and reliability, every conversation about industrialisation, digital transformation and economic diversification will continue to run into the same obstacle. The country’s biggest power challenge is no longer proving that it has the resources. It is proving that it can deliver them consistently.
