Nigeria was plunged into a nationwide blackout on Friday, January 23, 2026, following the total collapse of the national electricity grid. This incident marks the first system-wide failure of the new year, occurring less than a month after a similar breakdown on December 29, 2025. The collapse has effectively paralysed economic activities and domestic life across the country’s 36 states and the Federal Capital Territory.
The system failure occurred at approximately 12:40 PM, according to data from the Nigerian Independent System Operator (NISO). In a matter of minutes, electricity generation plummeted from an average of 4,500 megawatts (MW) to zero. All 23 power generation plants connected to the national grid reportedly lost output, leaving the 11 electricity distribution companies (DisCos) with no power to supply their customers.
NISO confirmed the disturbance in an official statement, citing a "system-wide disturbance" that affected the entire interconnected network. Preliminary operational reports indicate that the collapse was triggered by the simultaneous tripping of multiple 330 kV transmission lines. This technical failure was compounded by the sudden disconnection of several grid-connected generating units, creating a cascading effect that the system’s safety mechanisms could not contain.
The Nigerian Independent System Operator stated that a detailed investigation into the root and contributory causes of the disturbance is currently ongoing. The management emphasised that "the full restoration and stabilisation of the grid remains a top operational priority." Following the outage, restoration activities officially commenced at about 1:15 PM in accordance with established recovery procedures.
By early evening, some progress had been reported in the "black start" restoration process. NISO announced that supply had been successfully returned to key nodes, including Abuja, Osogbo, Benin, Onitsha, Sakete, Jebba, Kainji, and Shiroro, as well as parts of Lagos. However, many major cities remained in darkness as engineers worked to synchronise the rest of the network.
The Abuja Electricity Distribution Company (AEDC) issued a public notice to its customers, confirming the 12:40 PM disturbance and apologising for the inconvenience. The company noted that while gradual restoration had begun, full stability would take time. Similarly, the Eko Electricity Distribution Company (EKEDC) informed its subscribers that it was working closely with partners at the Transmission Company of Nigeria (TCN) to restore supply to the Lagos axis.
