In the past 10 hours, Nigerians have been in darkness, following the total system collapse of the national grid today.
The system collapse which occurred at about 11:01am was caused by voltage collapse at some parts of the national grid
The national grid is controlled and operated by government-owned Transmission Company of Nigeria.
Power system collapse is the process by which the sequence of events accompanying voltage instability leads to an unacceptable voltage drop in a significant part of power system.
According to TCN General Manager, Ndidi Mbah told vanguard in a chat that at about 11.01 am today, 12th of May, 2021, there was a total system collapse of the grid, as a result of voltage collapse at some parts of the grid.
She stated that TCN has commenced grid recovery immediately after the collapse, from Shiroro Generating Station to Katampe TS, Abuja through the Shiroro – Katampe line at 11:29 am, and also through Delta Generating Station to Benin Transmission Substation and has reached Osogbo and parts of Lagos.
“While the grid restoration and power restoration gradually progress to other parts of the country, the cause of voltage collapse that precipitated this failure is equally being investigated.
“TCN appeals for patience as it works assiduously to ensure full restoration of the grid and consequently power supply to the remaining parts of the country,” she added.
Meanwhile, in separate messages to their customers, the electricity distribution companies have called for calmness, stressing that they are working with TCN to resolve the development.
Eko Electricity Distribution Company Plc, in a text message to its customers, said, “Dear customer, there is a partial system collapse on the national grid. Our TCN partners are working to restore supply immediately. Please bear with us.”
