Nigeria’s long-standing electricity challenges have come into sharp focus again, as the national grid recorded a drop in power generation to 3,940 megawatts in March 2026—an amount widely considered inadequate for a population of over 220 million.
Despite over a century of electricity generation dating back to 1896, the country continues to struggle with limited and unstable power supply. Official data indicates that while Nigeria has an installed generation capacity of about 13,000MW, only between 4,000MW and 5,000MW is typically transmitted on a good day due to infrastructural and operational constraints.
In comparison, South Africa produces over 48,000MW for a population of around 60 million, while Egypt boasts approximately 59,000MW installed capacity serving about 110 million people.
The national grid remains fragile, having recorded 12 collapses in 2024 alone, according to industry data. Over a 12-year period between 2010 and 2022, the Nigerian Electricity Regulatory Commission (NERC) documented at least 222 partial and total system collapses—averaging one every three weeks.
Infrastructure vandalism has further compounded the crisis. In 2024, no fewer than 128 transmission towers were destroyed, costing the government approximately N8.8 billion in repairs.
Restarting key power plants after grid failures also carries significant financial implications. Rebooting facilities such as Azura Power Plant, Delta Power Plant, and Shiroro Hydropower Plant costs an estimated $25 million (about N42.5 billion) per incident.
The sector is also grappling with mounting debt. As of February 2026, liabilities owed to generation companies stood at N6.8 trillion and are projected to hit N7 trillion by the end of March. Of this amount, about N3.3 trillion is owed to gas suppliers, leading to a sharp reduction in gas supply to thermal plants. Current supply stands at less than 43 percent of required levels, severely limiting electricity generation.
In response, the federal government approved N4 trillion in bonds to stabilize the sector, although only N590 billion has been issued so far.
Meanwhile, Nigerians continue to rely heavily on alternative power sources. It is estimated that about 22 million generators are in use nationwide, with a combined capacity of roughly 42,000MW—significantly higher than the output of the national grid. Annual spending on generators and fuel is estimated at $14 billion.
The unreliable power supply has had a devastating impact on businesses. In 2023 alone, 767 manufacturing companies shut down, while 335 others became distressed, resulting in approximately 18,000 job losses. The situation worsened in 2025, with manufacturers spending N676.6 billion on backup power in the first half of the year, yet still facing operational challenges that led to nearly 19,000 additional job losses.
According to the World Bank, power outages cost Nigeria an estimated $29 billion annually—equivalent to about 10 percent of the country’s Gross Domestic Product.
Experts argue that the crisis is less about capacity and more about governance and systemic inefficiencies. While countries such as Ghana have stabilized and now export electricity, and South Africa has made progress in reducing outages, Nigeria continues to face persistent challenges despite multiple reform efforts and over $4 billion in international loans since 1999.
Industry stakeholders warn that without comprehensive reforms and sustained investment, Nigeria’s ambition to become a globally competitive economy may remain out of reach, as reliable electricity remains a critical foundation for industrial growth and development.
