Nigeria’s national power grid reportedly suffered another collapse on Tuesday, impacting several regions and plunging parts of the country into darkness.

Around 1:39 p.m., the grid’s power generation began to decline sharply, with reports showing an initial drop from 2,711 megawatts at 1 p.m., compared to an earlier peak of 3,631 MW.

Before this, the grid had reached 3,934.77 MW early in the morning around 6 a.m., indicating that power output was fluctuating even before the collapse.

However, the situation deteriorated further between 2 p.m. and 3 p.m., when power generation dropped completely to zero, according to industry monitors.

The Transmission Company of Nigeria (TCN) later issued a statement acknowledging what it described as a “partial disturbance” in the national grid at 1:52 p.m. Ndidi Mbah, TCN’s spokesperson, attributed the incident to a sequence of line and generator failures that led to significant instability in the grid system.

She explained that while a major section of the grid experienced a power disruption, data from the National Control Centre indicated that not all areas of the grid were impacted equally, with some areas maintaining minimal service.

TCN officials noted that efforts were underway to restore power supply to the affected regions as quickly as possible.

Engineers were reportedly dispatched to assess and stabilize the disrupted lines and generator units.

By 2:49 p.m., power had been successfully restored to the Abuja area, with ongoing efforts to gradually bring other affected areas back online.

“We are working to reinstate bulk power supply across the country and hope to have full service soon,” Mbah said, adding that they regretted any disruption caused to households, businesses, and essential services dependent on consistent electricity.

This incident follows a series of recent power instability issues in Nigeria, where grid failures and inconsistent electricity supply have long been a challenge for both the government and private sectors.

Over the years, these disruptions have sparked conversations on the urgent need for energy sector reforms.
