Nigeria’s fragile power system suffered another setback on Tuesday after a disturbance on the national grid caused electricity outages in several parts of the country.
The Nigerian Independent System Operator (NISO) has confirmed that the incident was not a total grid collapse, contrary to early reports, but a partial system failure triggered by a voltage disturbance at the Gombe transmission substation.
According to NISO, the problem started in Gombe and quickly spread across the transmission network. As a result, several transmission lines and power-generating units tripped.
Within minutes, the disturbance reached other key substations, including:
Jebba Transmission Substation
Kainji Transmission Substation
Ayede Transmission Substation
At the peak of the incident, power generation dropped to zero megawatts at about 11:00am, a situation that immediately affected supply in many areas.
In simple terms, the grid “shook,” but it did not completely crash.
In a statement issued on Tuesday, NISO moved quickly to clear the air.
“The national grid has been fully restored, and electricity supply across the affected areas has returned to normal,” the system operator said.
NISO stressed that the incident only affected parts of the grid, not the entire system.
“The event resulted in a partial system collapse, not a total collapse,” the statement added.
Technical teams, according to NISO, swung into action immediately and restored supply within hours.
By Tuesday afternoon, electricity had returned to affected areas. However, the incident has once again raised serious concerns about the stability of Nigeria’s power infrastructure.
This latest disturbance is the second grid incident recorded in 2026, and it comes barely weeks after the country ended 2025 with another grid collapse on December 29.
In fact, 2025 alone recorded multiple grid collapses, a trend that has left Nigerians frustrated and tired.
As many Nigerians would say, “Na so we go dey?”
For households and businesses, every grid failure means the same thing: darkness, damaged appliances, higher fuel costs, and lost income.
Small business owners feel it first. Welders, barbers, cold-room operators, and shop owners all suffer once power drops. And when outages happen too often, confidence in the system drops with it.
Despite repeated assurances, grid disturbances have become almost routine.
Experts say Nigeria’s power grid remains overstretched and sensitive to faults. A single voltage issue can now ripple across multiple states within seconds.
Until major upgrades, better coordination, and stronger maintenance culture take place, grid incidents may continue to occur.
For now, power has returned. But for many Nigerians, the bigger worry remains: how long before the next blackout?
As the saying goes, “Light don come, but make we no relax.”
Intensive work should be done to avoid a repeat of this same power grid failures in the future.
