TCN investigates latest national grid collapse, restores power

The Transmission Company of Nigeria (TCN) has commenced investigation into the collapse of the national grid  early Monday that plunged the country into total darkness.

TCN’s General Manager, Public Affairs, Ndidi Mbah, said this in the statement, “The National Control Centre (NCC) said a full-scale investigation is being conducted to establish and ascertain the cause of the partial disturbance as this unwholesome event has resulted in aggregated generation loss.”

The company also disclosed that it had restored power across the country hours after the grid collapse.

It stated, “The restoration of the affected parts of the grid commenced immediately at 11.55 am with Osogbo/Ihovbor back to the grid followed by Jebba/Osogbo, Kainji/Jebba, Benin/Onisha, Shiroro/Kaduna, Shiroro/Katampe, and Alaoji/Ikot-Ekpene.

“Others are Lokoja/Gwagwalada, Odukpani/Ikot Ekpene, Benin/Omotosho, Oke-Aro/Ikeja west, Egbin/Oke-Aro and Kaduna/Kano.”

The TCN said the immediate report from its officials showed “a sudden drop in system frequency, which created system instability”.

Earlier, electricity distribution companies had informed their customers of the disruption of power, citing the collapse of the national grid.

Ikeja Electric said the national grid collapsed at 10:50am on Monday, noting that “this has affected the transmission stations within our network and resulted in the loss of power supply to our customers”.

The DISCOs equally apologised to them, saying work was being done to fix the issue.

“We are working with our TCN partners to restore supply as soon as possible,” Eko Electricity Distribution Company also said.

The national grid had collapsed seven times this year with the last one coming in July. It equally collapsed in June, March and April 2022.
