Africa-Press – Nigeria. <\/strong><\/span>The Transmission Company of Nigeria (TCN) on Thursday said restoration of the national grid is almost completed following its collapse on Wednesday.<\/p>\n

Mrs Ndidi Mbah, TCN General Manager, Public Affairs, said this in a statement made available to newsmen in Abuja.<\/p>\n

Mbah said that the national grid experienced system disturbance at about 11:27a.m. on Wednesday, but that its restoration was almost completed as at 11:00p.m.<\/p>\n

\u201dThe incident was as a result of a sudden drop in system frequency from 49.94 Hertz (HZ) to 47.36Hz, which created system instability,\u201d she said.<\/p>\n

Hertz is a unit of frequency which replaces the earlier term of one cycle per second (cps).<\/p>\n

Mbah said that reports from the National Control Centre (NCC), revealed that the collapse was precipitated by the tripping of a unit with a load of 106 Megawatts (MW) in one of the generating stations due to \u201cExhaust over Temperature\u201d.<\/p>\n

She said the tripping pulled out other grid-connected units in the plant, which resulted in aggregated generation loss of 457MW.<\/p>\n

\u201cA train of events ensued, culminating in the collapse of the national grid.<\/p>\n

\u201cAs obtainable in all systems, when a component of the electric power system is defective, the entire configuration is vitiated,\u201d she said<\/p>\n

Mbah said investigation was going on to establish the cause of the failure.<\/p>\n

She said the Nigerian Electricity Supply Industry (NESI) appreciated the understanding of the government and consumers of electricity within and outside the country.<\/p>\n

Mbah said that NESI was committed to leveraging on interventions instituted this far to enhance power supply reliability.<\/p>\n
