Nigeria’s electricity sector has entered a new phase of regulatory tightening as the Nigerian Electricity Regulatory Commission introduces sweeping new rules aimed at reducing long-standing inefficiencies in power transmission and improving accountability across the national grid. The latest directive, issued under Order No. NERC/2026/026, represents one of the most structured attempts in recent years to confront the technical and operational losses that continue to weaken electricity delivery despite ongoing reforms in the sector.
At the centre of the new framework is a renewed focus on transparency, data accuracy, and enforceable performance benchmarks. For years, transmission losses have remained a critical challenge in Nigeria’s power system, contributing not only to unstable supply but also to disputes over billing, tariff assumptions, and system planning. The regulator’s latest intervention signals a shift from broad policy guidance to more measurable, enforceable obligations placed on key institutions managing the grid.
Data from the Nigerian Independent System Operator shows that Nigeria’s national average transmission loss factor stood at 8.71 percent in 2024. While this improved to 7.24 percent in 2025, it still exceeds the 7 percent benchmark established under the Multi-Year Tariff Order framework. The gap, though seemingly small in percentage terms, translates into significant financial and energy inefficiencies when applied across the country’s large and complex transmission network.
Transmission losses typically occur when electricity is lost during bulk movement from generation stations to distribution load centres. In practical terms, it means a portion of generated power never reaches end users, despite being accounted for within the system. In Nigeria’s case, these losses are driven by a combination of ageing infrastructure, overloaded transmission lines, weak monitoring systems, and operational inefficiencies within key nodes of the grid.
The new order, which is scheduled to take effect from 13 April 2026, is grounded in the provisions of the Electricity Act 2023, which significantly expanded the regulatory authority of the commission over efficiency standards and market oversight. The Act has been widely viewed as a turning point in Nigeria’s power sector governance, particularly in its emphasis on performance-based regulation and institutional accountability.
One of the most notable provisions of the new directive is the mandatory installation of smart meters at all regional interconnection boundary points by December 2026. These boundary points are critical junctures where electricity flow is transferred between different operational regions of the grid. Historically, these points have been difficult to monitor with precision, leading to disputes over reported losses and actual system performance.
By introducing real-time measurement infrastructure at these points, the regulator aims to eliminate guesswork and replace estimations with verifiable data. The requirement also extends to energy flow measurement at power transformers within transmission substations, a move designed to create a more granular understanding of where losses occur within the system.
Under the new framework, the Transmission Company of Nigeria has been directed to submit a detailed action plan by July 2026. That plan must outline concrete steps to reduce transmission losses to within approved benchmarks, with an additional performance target set at no more than 6.5 percent across all regions by December 2026.
This target is particularly ambitious when viewed against historical performance trends. Nigeria’s transmission infrastructure has struggled for years with underinvestment, maintenance backlogs, and capacity constraints. In many cases, demand growth has outpaced system upgrades, leading to overloading of critical lines and increased technical losses. The new directive effectively places measurable pressure on the system operator to accelerate corrective actions within a relatively short timeframe.
Beyond technical improvements, the order also introduces a stronger reporting regime. The Nigerian Independent System Operator will now be required to submit quarterly regional reports detailing transmission losses across the country. These reports are expected to standardise how losses are measured and presented, reducing inconsistencies that have previously complicated regulatory oversight and policy decisions.
For regulators, one of the key concerns has been the lack of uniformity in loss reporting. Different regions and operational units have often used varying assumptions or methodologies, making it difficult to establish a single, reliable national picture. The new system is designed to address this by enforcing a unified measurement framework supported by digital metering infrastructure.
The implications of these changes extend beyond regulatory compliance. Transmission losses directly influence electricity pricing, particularly under tariff systems that rely on cost-reflective assumptions. When losses are high or poorly measured, the financial burden is often distributed across consumers and market participants, sometimes leading to disputes over fairness and efficiency.
By improving accuracy in loss measurement, the regulator is also aiming to strengthen confidence in tariff-setting mechanisms and improve overall market stability. Better data should enable more precise planning, more efficient investment decisions, and a clearer understanding of where infrastructure upgrades are most urgently needed.
The commission has also emphasised that the reforms are not solely about enforcement but about long-term system improvement. Accurate data, it argues, is foundational to building a stable electricity market. Without it, even well-designed policies risk being undermined by uncertainty and misallocation of resources.
However, industry observers note that implementation will be the true test of the policy. While regulatory frameworks in Nigeria’s power sector have often been well-articulated on paper, execution has historically faced challenges ranging from funding constraints to institutional coordination gaps. The success of the new order will therefore depend heavily on the ability of key stakeholders to meet deadlines, deploy required infrastructure, and maintain consistent reporting standards.
Still, the direction of policy is clear. The Nigerian electricity market is moving toward a more data-driven and performance-monitored system, where inefficiencies are quantified in real time and tied directly to accountability mechanisms. If fully implemented, the reforms could mark a significant step toward reducing one of the sector’s most persistent technical bottlenecks.
For now, attention shifts to the coming months, as institutions begin to align with the new requirements. The rollout of smart meters, submission of action plans, and establishment of quarterly reporting systems will serve as early indicators of whether Nigeria’s power sector is ready to translate regulatory ambition into measurable improvement on the grid.
