Energy Economist Warns Nigeria's Electricity System Is Collapsing Under Its Own Weight
Energy economist Obianuju Ezenwanne has issued a stark warning that Nigeria's electricity system is under severe strain, describing the sector as a complex network of failures that reinforce each other, making persistent power outages almost inevitable. In a detailed statement, Ezenwanne emphasized that many Nigerians underestimate the scale of the crisis, noting deep structural weaknesses across generation, transmission, and distribution infrastructure.
"Most people do not realize how deep the problem goes," she said. Ezenwanne, who studies power system planning and regulation at the Missouri Public Service Commission in the United States, reviews utility filings, electricity demand forecasts, and long-term infrastructure investments. Drawing from this experience, she explained that Nigeria's power sector reveals troubling patterns when analyzed through a similar lens.
Systemic Failures Across the Electricity Value Chain
According to Ezenwanne, the challenge is not merely a shortage of power plants or fuel supply. "The problem is not just a lack of power plants or fuel. It is a system problem. Generation, transmission, and distribution all have weaknesses, and they interact in ways that make outages unavoidable," she elaborated. She highlighted that although Nigeria has over 13,000 megawatts of installed generation capacity on paper, the national grid in reality delivers less than 4,000 megawatts to a population exceeding 200 million people.
This large gap between installed and delivered capacity reflects multiple failures across the electricity value chain. Ezenwanne detailed the issues:
- Most Nigerian power plants rely on natural gas, but pipelines are frequently vandalized or sabotaged, disrupting fuel supply and forcing facility shutdowns.
- Several plants underperform due to ageing infrastructure and inadequate maintenance.
- Even when electricity is generated, it must pass through an overstretched and failure-prone high-voltage transmission network.
- At the distribution stage, wires, feeders, and transformers are often outdated, inefficient, and poorly maintained.
Cycle of Instability and Economic Impact
The result, she said, is a cycle of instability that Nigerians have grown accustomed to. Repeated grid collapses compel businesses and households to rely heavily on diesel-powered generators. While these generators keep hospitals running, restaurants operating, and small businesses afloat, they also raise operating costs and contribute to inflation across the economy.
Ezenwanne stressed that a clear understanding of how the electricity system functions is the first step toward addressing the crisis. "When you look at where the bottlenecks are—the gas supply, the transmission lines, and the distribution networks—you can see what needs urgent attention," she noted.
Opportunities and Challenges Amidst Reforms
Her analysis comes at a critical moment for Nigeria's power sector. The Electricity Act of 2023 has decentralized parts of the industry, granting states greater authority to regulate their own electricity markets. States such as Lagos, Edo, and Enugu are now exploring state-level electricity frameworks, a development that presents both opportunities and challenges as they attempt to balance affordability, reliability, and long-term investment.
Ezenwanne said lessons from her work in Missouri highlight the importance of carefully analyzing the entire electricity ecosystem, from power plants and fuel supply to transmission infrastructure and customer metering systems. For Nigeria to resolve its electricity crisis, she asserted that reforms must occur simultaneously across several areas:
- Gas pipelines need to be repaired and secured.
- Power plants must be properly maintained and upgraded.
- Transmission networks should be expanded and reinforced.
- Distribution infrastructure requires modernization.
"Nigeria's electricity crisis affects every part of daily life. Every business, every hospital, every home feels it. Understanding the system is the first step toward making sure the lights stay on for everyone all the time," she concluded.
