The Transmission Company of Nigeria (TCN) disclosed on Saturday that line trippings caused the power fluctuations experienced in some parts of the country.
Ndidi Mbah, the TCN spokesperson, while stating in a statement that the national grid did not experience a collapse on Saturday, disclosed that the Ihovbor line tripped at 1:41 pm, which was followed by the tripping of the Benin-Omotosho line.
Mbah, while noting that trippings, which affected bulk power supply to the Lagos axis only, explained that the line tripping disrupted operations at Egbin, Olorunsogo, Omotosho, Geregu, and Paras power stations. While these facilities have since been restored, she added that the restoration of the Benin-Omotosho 330kV line was still ongoing as of Saturday evening.
“Earlier today, at about 13:41 hrs, the Osogbo-Ihovbor line tripped, followed by the tripping of the Benin-Omotosho line. These consequently affected bulk supply only on the Lagos axis.
“It is important to clarify that at about 13:00 hrs today, just before the tripping, total generation on the grid was 4,335.63 MW. After the trippings, however, generation dropped to 2,573.23 MW, showing clearly that the grid did not experience a collapse.
“The transmission line tripping affected Egbin, Olorunsogo, Omotosho, Geregu, and Paras power stations. These have all been restored except for the Benin-Omotosho 330kV line, whose restoration is ongoing,” Mbah stated.
