Nigeria’s electricity transmission losses have fallen to 7.05 per cent, down from nearly 10 per cent recorded earlier, according to the Nigerian Independent System Operator (NISO). Managing Director Abdu Bello announced the improvement during NISO’s first anniversary event in Abuja, citing targeted operational interventions aimed at boosting efficiency across the transmission network.
The reduction is significant, as high transmission losses had previously drained between N5 billion and N8 billion monthly from the electricity market. Bello attributed the progress to better coordination among generation, transmission, and distribution segments, alongside stricter monitoring of grid operations.
A key factor in the improvement has been the enforcement of free governor mode of operation for generating companies, which allows power plants to automatically adjust output in response to fluctuations in system frequency. This measure has enhanced grid stability and reduced frequency deviations, though full compliance from all operators is still pending. Bello noted that enforcement actions would be taken against defaulting generation companies to ensure continued progress.
NISO is also advancing its digital transformation by scaling up Internet of Things (IoT) technology across the electricity value chain. Distribution companies have been mandated to install IoT meters on their 33kV and 11kV feeders. Combined with ongoing SCADA/EMS implementation, these upgrades will enable real-time grid monitoring, improve data accuracy, and accelerate market settlements.
The improvements come as part of broader efforts to stabilise Nigeria’s power sector, which has long struggled with inefficiencies and financial losses. NISO aims to further reduce transmission losses to between five and six per cent, signalling a continued push toward a more reliable and cost-effective electricity supply for the country.
