Why national grid collapses again – TCN
Following an embarrassing experience faced by Nigerians over the fresh collapse of the national grid, the Transmission Company of Nigeria has explained that the ongoing repair works in the power sector were the critical factor responsible for Thursday’s grid collapse.
According to a statement by TCN spokesperson Ndidi Mbah, the national grid experienced a disturbance at approximately 11:29 am on Thursday, caused by a sudden rise in frequency from 50.33Hz to 51.44Hz.
She said, “Recovery efforts began immediately, and the Abuja Axis was restored within 28 minutes. Recovery is still ongoing,” she said, even though many residents reported they had yet to receive power supply since the first grid collapse on Tuesday.
“The frequency spike was caused by issues encountered at one of TCN’s substations, which had to be shut down to prevent further complications. In addition, we are actively engaged in significant repair works on several critical transmission lines and substations.
“This includes the 330kV transmission lines along the Shiroro–Mando axis, major upgrades at the Jebba Transmission Substation, and the restoration of the second Ugwuaji–Apir 330kV transmission line.
“Furthermore, following the submission of the investigative report on the causes of previous grid collapses, we have begun addressing the identified weaknesses in the transmission system.
“Efforts are being made to close the gaps highlighted in the report and to enhance the overall stability and resilience of the grid. These efforts include both technical upgrades and strategic interventions based on the committee’s recommendations,” Mbah added.
However, she noted that while the repairs and improvements are underway, some degree of instability in the system is likely to persist until all major works are completed.
“We acknowledge the impact of these disruptions and ask for the understanding and patience of the public during this challenging period.
“TCN remains committed to improving the reliability of electricity supply, recognising the vital role that stable power plays in Nigeria’s socio-economic development.
“We assure the public that all necessary measures are being taken to ensure the grid’s long-term stability, in line with the recommendations of the investigative committee, while also addressing infrastructure damage, such as vandalised transmission lines,” she said.
The Informant247 had earlier reported how the National Grid suffered another collapse three days after experiencing the ugly incident.
The recent collapse, around 11:28 am on Thursday, is the second this week and the 10th in 2024.
A check on Independent System Operator, an autonomous arm of the Transmission Company of Nigeria (TCN), showed all power plants connected to the grid didn’t produce any electricity around 12 pm.
