The electricity National Control Centre (NCC) in Osogbo, Osun State has commenced a full-scale investigation to establish and ascertain the cause of the partial disturbance that resulted in Monday power system collapse, the Transmission Company of Nigeria (TCN) has announced.
The collapse, TCN said, has resulted in aggregated generation loss.
Recall that nearly 10 hours after a blackout, the national power grid, which collapsed for the eighth time this year, was restored in parts of the country, including the Federal CapitalTerritory, Abuja.
The Transmission Company of Nigeria (TCN) General Manager, Public Affairs, Mrs Ndidi Mbah, explained that the incident was as a result of sudden drop in system frequency, which created system instability.
“The restoration 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.”
However, she said the grid restoration is almost completed and the Nigerian Electricity Supply Industry (NESI) regreted any inconveniences caused and appreciates the kind understanding of electricity consumers within and outside the country.
She assured the commitment of leveraging the concerted interventions instituted so far to enhance power supply reliability so that the issue of system disturbance would soon become outdated.
Reports from electricity distribution companies showed restoration resumed hours after the collapse at 10.51 a.m. on Monday. Ibrahim Sani Shawai, a deputy general manager, Kano Electricity Distribution Company (KEDCO), said, “This is to inform our numerous customers that the system collapse at the national grid that led to power outage is being addressed,” the statement reads.
“As at 3:26 pm, 50MW of electricity was wheeled to KEDCO which is being distributed equitably across our franchise.
“We are expecting improvement in supply in the coming hours and days and we will ensure speedy supply as soon as we get more megawatts.”
On the South-Eastern flank, the Enugu Electricity Distribution Company (EEDC), in a separate statement, said, “This is to inform you that after the system collapse earlier today, September 26, 2022, two of our interface TCN stations at Nibo and Awada received supply at 12:36 pm and 12:37 pm respectively, with a directive by NCC to maintain only 7MW,” it said.
“We are still on standby, hoping that full and normal supply will be restored to all other interface TCN stations.”
