Blackout as national grid suffers fresh collapse

By Sabiu Abdullahi

Nigeria was thrown into darkness on Monday after the national electricity grid experienced another system failure following a sharp drop in power generation.

Findings showed that the disruption occurred at about 3 pm when major power stations supplying electricity to the grid suddenly lost generation, forcing the system to shut down.

Data obtained from industry sources indicated that electricity output earlier rose to about 4,800 megawatts on Monday. The figure later fell steeply to 139 megawatts as of 3 pm, which triggered the collapse of the grid.

The immediate cause of the failure was not confirmed at the time of reporting. However, the incident happened while the Nigerian Independent System Operator was working to increase electricity supply after recent gas shortages that followed cases of pipeline vandalism.

Checks further revealed that as of the time this report was filed, all 22 power plants connected to the national grid had dropped off from electricity generation.

The development left several parts of the country without power supply, as distribution companies struggled to restore electricity to affected areas.

More details are expected as authorities continue to assess the situation.

Vandals strike again, damaging Lokoja–Gwagwalada transmission line

The Transmission Company of Nigeria (TCN) has reported another act of vandalism, this time targeting its 330kV Lokoja–Gwagwalada transmission line. 

This attack comes as Nigerians await the restoration of power following the recent sabotage of the 330kV Shiroro-Kaduna lines.

In a statement issued on Sunday by TCN’s General Manager of Public Affairs, Ndidi Mbah, the company revealed that the incident occurred in the early hours of Saturday, November 9, 2024. 

Vandals destroyed transmission towers T306, T307, and T308, disrupting power transmission along the affected route.

Efforts by TCN engineers to restore the line earlier on Saturday were unsuccessful when the line tripped. 

A subsequent inspection by TCN’s patrol team confirmed the vandalism, which included the theft of two spans of aluminium conductors. 

Although the double-circuit transmission line remains operational through line two, the company is working to replace the stolen components.

This incident is part of a worrying pattern of increasing vandalism targeting Nigeria’s power infrastructure, particularly in the Gwagwalada area. 

Previous attacks include the Gwagwalada–Kukuwaba–Apo transmission line on December 10, 2023, and the Gwagwalada–Katampe line on February 26, 2024. 

Such ongoing disruptions are severely hindering the stability and expansion of the national power grid.

TCN has once again called for cooperation from local communities and security agencies to address the rising threat of vandalism. 

The company stressed that these criminal activities undermine efforts to strengthen Nigeria’s transmission system and serve as a disservice to all citizens.

Power restored after temporary grid disturbance – TCN

By Uzair Adam

The Transmission Company of Nigeria (TCN) has addressed reports of a national grid breakdown on Saturday, describing the incident as a “temporary grid disturbance.”

The grid collapse, which occurred early Saturday morning, marks the third disruption this week, leaving many states in a total blackout.

According to data from the Nigerian System Operator’s portal (niggrid.org), the grid recorded zero Megawatts (MW) as of 8:16 a.m. on Saturday, with all 22 generation companies (GenCos) down.

This latest incident is the eighth grid disturbance recorded in 2024.TCN’s General Manager, Public Affairs, Ndidi Mbah, confirmed that power has since been restored, explaining that the disturbance was triggered by an explosion in the bus section of a current transformer at the 330kV Jebba Transmission Substation.

“The protection system responded immediately, opening the busbars to prevent further damage and the outbreak of fire,” Mbah said.

Engineers at the Jebba station were able to isolate the faulty transformer and reconfigure the busbar arrangement, restoring power to the station and other parts of the grid.

TCN nears full recovery of national grid after partial disturbance

By Uzair Adam  

The Transmission Company of Nigeria (TCN) has made significant strides in restoring the national grid after a partial disturbance on Monday evening.  

The incident, which occurred around 6:48 p.m., triggered an immediate response. 

In a statement on Tuesday, Mrs. Ndidi Mbah, TCN’s General Manager of Public Affairs, confirmed that recovery efforts began swiftly, with the Azura Power Station providing the essential blackstart to stabilise the grid. 

By 10:24 a.m. on Tuesday, the recovery process was in its advanced stages, despite a minor setback that briefly slowed progress.  

Mbah reassured the public that the TCN continued working to restore full power, with about 90% of the country’s substations already receiving bulk electricity.  

Power has been fully restored to Abuja and other key distribution centres. 

She added that the disturbance did not impact the Ibom Gas generating station, which remained functional and continued to supply power to areas in the South-South, including Eket, Ekim, Uyo, and Itu transmission substations.
