National Grid Restored After Nine Hours Of Nationwide Blackout

The Transmission Company of Nigeria (TCN), on Sunday, announced that the national grid, which experienced a partial disturbance yesterday, has been fully restored.

THE WHISTLER had previously reported that the grid collapse, which occurred for the fourth time in 2024, threw Nigerians into total darkness.

The incident, which occurred at approximately 15:09PM on July 6, 2024, and restored by 21:57PM, marked the third partial disturbance and the fourth overall grid disturbance this year.

However, TCN in a statement issued by its General Manager of Public Affairs, Ndidi Mbah, in Abuja, said the grid disturbance was triggered by the unexpected tripping of three units at a power generating station, resulting in a sudden loss of 313MW from the grid.

She said the restoration efforts began immediately after the incident, adding that by 21:57 hours on the same day, the affected sections of the grid were successfully restored.

“The Transmission Company of Nigeria, TCN, hereby states that there was a partial disturbance of the grid at about 15.09 hours yesterday, 6th July 2024.

“The system disturbance, which brings to three, the partial grid disturbances, with one total disturbance this year, is suspected to have been triggered by the unexpected tripping of three (3) units of a power generating station, which suddenly removed 313MW from the grid, causing system instability that led to the loss of bulk supply to a section of the national grid.

“Meanwhile, the System Operator reacted to the sudden drop in generation which led to a dip in frequency, by islanding a section of the grid which includes the Ibom Power Station through which the company continued to feed Uyo, Aba, Itu, Eket, Calabar e.t.c even when the other section of the grid had no supply.

“Also, the operators commenced grid restoration efforts immediately after the incident. At about 21.57 hrs yesterday, the entire part of the grid that was affected by today’s incident was successfully restored”, she said.
