The Nigerian Independent System Operator has announced the restoration of the national grid after multiple trippings on the 330-kilovolt transmission network on Monday, as electricity generation plunged from 3,840 megawatts to about 477MW, raising fresh concerns about stability. JUST IN: NISO refutes grid collapse claims, says partial system disturbance restored.
In a statement signed by its management on Monday, the operator said it worked with the Transmission Company of Nigeria to stabilise the system and restore normal operations. The statement read, “The Nigerian Independent System Operator wishes to inform the public that at approximately 12:40 hours on Monday, 19 October 2026, the national grid experienced multiple trippings on the 330kV transmission network.
NISO insisted it was not a total system collapse but multiple line trippings triggered by a fault on the Shiroro-Kaduna line, which caused frequency dip and automatic load shedding. Power was restored to Abuja, Lagos and Kano within three hours, with Minna getting supply at about 4pm yesterday. The incident comes as the Federal Government pushes solar initiatives that have powered 5 million people according to UN assessment published this morning. Energy experts say grid remains fragile due to lack of spinning reserve and call for urgent investment in SCADA.
