NISO Restores National Grid After Power Disturbance
On October 19, 2026, at approximately 12:40pm, the Nigerian Independent System Operator (NISO) reported multiple trippings on the 330-kilovolt transmission network, leading to a significant drop in electricity generation from 3,840 megawatts to about 477 megawatts. NISO clarified that the incident affected only a section of the grid and did not constitute a nationwide grid collapse, contrary to media claims.
In collaboration with the Transmission Company of Nigeria (TCN), NISO implemented corrective measures to stabilize the power system and successfully restored normal operations. The statement emphasized that the reported outages could be attributed to local issues rather than a grid-wide failure.
NISO urged the public to rely on its official communication channels for updates and reaffirmed its commitment to maintaining grid stability and providing timely information.
