Nigeria’s national electricity grid collapsed again on Tuesday, plunging several parts of the country into darkness and disrupting power supply nationwide.
AIT’s Yemi Adebayo reports that this is the second grid collapse in just four days, following a similar outage last Friday.
A check on the website of the Nigerian Independent System Operator (NISO) showed that all the Discos were not allocated supply as at 10:54 am.
At the time of Tuesday’s collapse, only Delta Gas Power Plant was generating electricity, contributing 39 megawatts to the grid, while all other electricity distribution companies (Discos) were not allocated supply.
The Nigerian Independent System Operator (NISO) had explained that preliminary operational reports indicated the collapse was caused by the simultaneous tripping of multiple 330kV transmission lines, alongside the disconnection of some grid-connected generating units.
The repeated grid failures in a short period have raised serious concerns among consumers, businesses, and industry stakeholders about the reliability of Nigeria’s power infrastructure.
Many businesses reported disruptions in operations, while households were forced to rely on generators and alternative energy sources.
Energy experts have warned that such frequent collapses pose risks to industrial productivity and economic growth, noting that the national grid requires urgent technical upgrades, proper maintenance, and investment in generation capacity to prevent recurring outages.
A detailed investigation into the root and contributory causes of the disturbance is ongoing, as full restoration and stabilization of the national grid remain top operational priorities for NISO and the Transmission Company of Nigeria (TCN).
