Nigeria’s electricity crisis has taken a troubling turn as Electricity Distribution Companies (DisCos) recorded a staggering ₦2.4 trillion in financial losses over a two-year period, further weakening the already fragile power sector.

The losses, driven largely by poor billing systems and weak revenue collection, highlight deep structural inefficiencies in the Nigerian Electricity Supply Industry (NESI). Data shows that DisCos lost about ₦1.015 trillion in 2024, with the figure rising sharply by over 31 percent to ₦1.334 trillion in 2025, bringing the cumulative total to approximately ₦2.349 trillion.

A closer breakdown reveals that billing inefficiencies accounted for about ₦649.87 billion of the 2025 losses, while collection challenges contributed ₦684.28 billion, underscoring persistent leakages in the system.

The financial strain has worsened liquidity across the power value chain, where the entire sector is already burdened with debts estimated at over ₦6 trillion. This has significantly affected power generation, as generation companies (GenCos) struggle with unpaid invoices, forcing many plants to operate below capacity due to inadequate gas supply.

As a result, electricity generation has declined, dropping from an average of about 4,600 megawatts in 2025 to below 3,500 megawatts in early 2026. This sharp decline has led to widespread blackouts and increased load shedding across the country.

Consumers nationwide are bearing the brunt, with many households and businesses experiencing prolonged outages. In several areas, electricity supply has fallen to less than 12 hours daily, while some communities receive as little as four to six hours of power, forcing residents to rely heavily on alternative energy sources.

The worsening situation has sparked growing frustration among consumers, who continue to decry estimated billing, lack of transparency, and poor service delivery by DisCos. Calls for mass metering and urgent sector reforms have intensified as Nigerians demand accountability and improved performance.

Meanwhile, the crisis has reached critical levels, with even government institutions exploring alternatives. The Presidential Villa in Abuja, for instance, is reportedly moving toward an independent solar power system to guarantee uninterrupted electricity supply—an indication of declining confidence in the national grid.

Industry experts warn that without urgent reforms—including improved metering, cost-reflective tariffs, and better financial discipline—the power sector risks further deterioration, leaving millions of Nigerians in prolonged darkness.
