The Transmission Company of Nigeria (TCN) has announced the restoration of part of the national grid that experienced partial system disturbance at about 10.51am on Monday.
According to a statement issued Monday evening, the incident was a result of sudden drop in system frequency, which created system instability.
The statement added that repair of the affected part of the grid commenced immediately at 11.55am 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 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 statement added that the grid restoration is almost completed and the Nigerian Electricity Supply Industry (NESI) regrets any inconveniences caused as well as appreciates the kind understanding of customers of electricity within and outside the country.
“We are committed to leveraging the concerted interventions instituted so far to enhance power supply reliability so that the issue of system disturbance will soon become outdated,” the statement said.
