The Nigerian Independent System Operator (NISO) has announced a significant reduction in electricity transmission losses, marking a notable improvement in the efficiency of Nigeria’s power grid.
According to the agency, transmission losses have dropped to 7.05 per cent, down from levels close to 10 per cent recorded at its inception. The development was disclosed by NISO’s Managing Director, Abdu Bello, during the organisation’s first anniversary in Abuja.
The reduction is the result of targeted operational reforms aimed at improving coordination across the electricity value chain, including generation, transmission, and distribution. Officials say these interventions have helped address inefficiencies that previously cost the sector between ₦5 billion and ₦8 billion monthly.
Beyond cutting losses, NISO is also pushing broader grid stability reforms. A key measure is the enforcement of “free governor mode” operations among power generation companies, ensuring that power plants automatically respond to fluctuations in system frequency. This has already led to improvements in grid reliability and reduced system instability.
The agency is further investing in technology to modernise the grid, including the rollout of Internet of Things (IoT) systems and advanced monitoring tools that will allow real-time tracking of electricity flow across the network. These upgrades are expected to improve transparency, efficiency, and response time to faults.
While the current progress is being described as a milestone, NISO says it is working to reduce transmission losses even further to around 5–6 per cent, in line with regulatory targets.
