    Why national grid collapsed – NISO

    The Nigerian Independent System Operator (NISO) said the grid collapsed at 10:48 hours on Tuesday because a voltage disturbance originated from the Gombe Transmission Substation.

    The Nation reported there was a nationwide outage due to grid collapse.

    But the management of NISO in a statement titled: “Update on partial system disturbance on the national grid,” explained: “The Nigerian Independent System Operator (NISO) wishes to state that at approximately 10:48 hours on January 27, 2026, the national grid experienced a voltage disturbance which originated from the Gombe Transmission Substation.”

    NISO further said the voltage disturbance rapidly propagated across the network, affecting Jebba, Kainji, and subsequently Ayede Transmission Substations. 

    The event, said the management, was accompanied by the tripping of some transmission lines and generating units, resulting in a partial system collapse.

    The statement reads in part: “Appropriate corrective actions were immediately implemented to stabilise the system and restore normal operations. Restoration, which began at about 11:11am has since been completed.

    “The incident only affected part of the grid therefore not a total collapse as reported by some media organizations. Additional information can be obtained from our website: www.niso.org.ng.

    “The national grid has been fully restored and electricity supply across the affected areas has since returned to normal.”

    The Nigerian Electricity Supply Industry (NESI) was in a distress state whren generation dipped to 39MW  from only Delta (Gas) plant at 11:00 hours, when The Nation visited the website of the NISO.

    The system crashed from the 3,825MW recorded at 10:00 hours.

    According to its Electricity Distribution Profile, the NISO sent a total of 195MW to only three energy distributors at 11:59 hours.

    The load was allocated as follows: Benin DisCo 65MW, Ibadan DisCo 50MW and Kaduna DisCo 40MW. 

    Eight DisCos were in total blackout as the recorded 0MW allocation.

    With this occurrence, the NESI has recorded the second grid collapse in 2026 after recovering from its January 23 experience.

    Speaking during the inauguration, Gbeleyi said the inauguration of the board  “serves as a crucial pillar in Nigeria Electricity Supply Industry (NESI) by ensuring that the System Operator (SO) and Market Operator (MO) function independently and transparently, fostering, efficiency, as well as boosting investor confidence.”

     “To the newly appointed members of the NISO’s Board, I congratulate you on your eminently deserved appointments and urge you to serve with diligence, integrity, and a deep sense of responsibility.

    “The success of NISO will no doubt play a crucial role in shaping the future of Nigeria’s power sector, and I am confident that with the right approach, focus and unflinching resolve, we will witness remarkable improvements in this regard
