The Nigerian Independent System Operator has warned that the nation’s economy hemorrhages approximately ₦40.1 trillion ($29 billion) annually due to a chronic and unreliable electricity supply that forces businesses and households into costly self-generation
The Nigerian Independent System Operator (NISO), a Federal Government agency, has sounded a grave alarm regarding the state of the nation’s power sector, revealing that Nigeria loses approximately ₦40.1 trillion ($29 billion) annually to poor electricity supply. According to the agency’s latest industry report, this staggering figure—calculated at a prevailing exchange rate of ₦1,385 to the dollar—represents one of the single biggest constraints to Nigeria’s economic growth, industrial productivity, and job creation. The operator noted that the unreliable nature of the national grid forces a massive reliance on self-generation, effectively creating an expensive “shadow grid” that siphons billions of naira from manufacturers and households every year
The agency emphasized that while there is significant demand and potential for expansion, structural bottlenecks across the entire value chain—spanning generation, transmission, and distribution—prevent generated electricity from reaching the final consumer. “Reliable electricity is one of Nigeria’s most important economic priorities. Power outages cost Nigeria an estimated $29bn annually. Businesses, manufacturers, and households spend billions each year generating their own electricity,” the system operator stated. The report further highlighted that a stable national grid is the primary key to unlocking latent economic opportunities, noting that current outages impose a “liquidity black hole” that sta crves the sector of necessary investment.
The impact of this energy deficit is felt most acutely in the industrial sector, where manufacturers are often forced to operate at a fraction of their installed capacity due to the high cost of diesel and petrol-powered generators. As of late March 2026, operational data indicated that power generation remains significantly below the required levels, with transmission limitations and gas supply disruptions cited as recurring hurdles. The NISO reiterated that bridging the gap between generation and delivery is critical for the country’s survival, stressing that “a stable national grid unlocks economic growth, industrial productivity, and job creation,” while the current failure continues to serve as a self-inflicted competitive disadvantage on the global stage.
