Nigeria entered 2026 with a familiar paradox: more generating plant than its grid can use. In January the Minister of Power, Adebayo Adelabu, said the country was drawing only a fraction of what its stations could produce, putting the stranded balance in the thousands of megawatts. Weeks earlier, at the Nigeria Energy conference in Lagos, he had described more than 10 GW of capacity as idle, a waste he called a drain on an economy starved of power.
The shortfall is structural rather than a lack of plant. Nigeria’s grid-connected stations carry an installed capacity of between roughly 13,000 and 15,500 MW, yet the Association of Power Generation Companies says generators can make only about 7,000 MW available, of which the transmission and distribution companies have been able to take just 4,000 to 4,500 MW, a ceiling that has barely moved since 2013. Average generation through January 2026 sat around 4,500 MW.
Two shocks deepened the squeeze early in the year. Between February and March, output slid below 3,000 MW as gas suppliers throttled deliveries to thermal plants over unpaid invoices and pipeline disruption, before recovering to about 4,300 MW by mid-April as gas supply climbed back above 700 million standard cubic feet per day. The system operator, meanwhile, put the cost of transmission inefficiencies at between ₦5bn and ₦8bn a month.
The sharpest verdict on grid reliability is the exodus from it. NERC data indicate that more than 250 manufacturers, tertiary institutions and large commercial users have left the public network to generate their own power, together producing an estimated 6,500 MW, more than the grid was delivering to the entire country at the time.
Why this matters
Why this matters for industrial and commercial users
For factories, hospitals and commercial estates, the question is not how much capacity Nigeria has built, but how much actually arrives, reliably, at the point of use. When generators can offer 7,000 MW and the grid evacuates barely half of it, and when more than 250 large users have already walked away to self-generate, grid supply reads as a planning risk rather than a planning assumption. That gap is what diesel and self-generation have filled for a decade, at considerable cost.
Embedded and captive generation answers the bottleneck directly. By siting power at or near the load, it sidesteps the transmission ceiling that strands capacity upstream. This is precisely what Nova Utilities builds: modular gas and solar plant that delivers to a defined customer rather than competing for room on a constrained grid. The stranded-capacity problem is, in effect, the business case for distributed power.
