NISO Reports 330kV Grid Trippings After Power Drop
On October 19, 2026, the Nigerian Independent System Operator (NISO) confirmed that multiple trippings occurred on the 330-kilovolt transmission network at approximately 12:40 PM. This incident followed a dramatic plunge in electricity generation, which fell from about 3,840 megawatts at 7 AM to just 476.70 MW by 1 PM.
NISO stated that while there were disturbances, the incident did not result in a total system collapse, affecting only a section of the national grid. In response, NISO collaborated with the Transmission Company of Nigeria (TCN) to implement corrective measures, successfully restoring normal operations.
NISO urged the public to disregard misleading reports suggesting a total grid collapse and to rely on official communication channels for accurate updates regarding the power system. The organization reaffirmed its commitment to maintaining grid stability and providing timely information on developments affecting the national electricity transmission system.
