TCN Announces Restoration Of National Grid After Nine Hours Of Nationwide Blackout

The Transmission Company of Nigeria (TCN) on Sunday announced the restoration of the national grid, which experienced a partial disturbance on Saturday.

Naija News earlier reported that the grid, which collapsed for the fourth time this year, had thrown Nigerians into total darkness.

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.

According to her, “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.”
