TCN restores collapsed national grid

By JOY ADARA, Abuja –

The Transmission Company of Nigeria (TCN) has said the nation’s collapsed grid has been fully restored.

TCN’s General Manager, Public Affairs. Mrs Ndidi Mbah, who revealed this in a statement in Abuja on Thursday, said that the collapse which occurred at about 12:20 p.m. was restored the same day at 4:59 p.m.

According to TCN, the collapsed Nation grid was triggered by a sudden drop in system frequency to 47.21Hz.

Mrs. Mbah said that reports received from Supervisory Control and Data Acquisition (SCADA) and other power generating stations showed that at about 12:20 p.m., two generating units tripped in one generating station.

“While four equally tripped in another generating station, causing a loss of 261MW and 350MW respectively, bringing the total loss of electricity on the grid to 611MW”.

“It is suspected that the sudden loss of 611MW from the grid caused system instability and its eventual collapse”.

“After the collapse, TCN’s system operators immediately commenced the restoration of the grid and by 12:46 p.m., power supply in Abuja was fully restored from Shiroro Generating Station at 1:05 PM”.

“TCN equally commenced grid restoration from the Delta Power Station, and at 4:59 p.m, a full restoration of the entire grid was achieved,’’ he said.

Mrs. Mbah said that TCN appreciates the government, electricity customers’ nationwide and international customers for their patience.

She said that TCN would continue to work hard to expand and maintain stability of the national grid.
