Understanding Nigeria’s power challenge

The common Nigerian exclamation "Up NEPA!", uttered whenever electricity returns after an outage, encapsulates the nation's enduring relationship with its power sector, even years after the National Electric Power Authority (NEPA) ceased to exist. This simple phrase underscores a deeper public struggle to comprehend the intricate journey of electricity from generation plants to household outlets, a journey fraught with complexities that often complicate debates on tariffs, privatization, and sector reforms.

To foster public understanding, this article clarifies fundamental concepts within Nigeria's electricity sector. The national grid is described as an interconnected network linking power generation to consumers, analogous to the national road network. Power is measured in megawatts (MW) and kilowatts (kW), with installed capacity representing a plant's maximum potential output, which often differs significantly from actual generation. Nigeria's installed capacity is around 14,000 MW, yet average delivery typically ranges between 4,100–5,000 MW.

Further definitions address critical issues like grid collapse, a widespread blackout triggered by supply-demand imbalance, and Aggregate Technical, Commercial, and Collection (ATC&C) losses. These losses, encompassing technical inefficiencies in aging equipment, commercial issues like unmetered customers and energy theft, and collection shortfalls, significantly impact distribution companies' revenue. The concepts of cost-reflective tariffs, which aim to cover the full cost of electricity provision, and alternative supply solutions like mini-grids and embedded generation, are also explained to provide a comprehensive overview of the sector's challenges and potential pathways forward.
