The affected areas were the Lagos axis, elements of the South West place, components of the North significant, and Abuja.
in the meantime, other regions, consisting of the South japanese vicinity, North East, and different elements of North significant and South West, had complete energy supply.
As an replace, TCN stated bulk strength were restored within the affected regions round 6:10 p.m. on Monday.
“The Transmission organisation of Nigeria (TCN) hereby notes that at approximately 6:10 p.m. the day past, fifth August 2024, electricity deliver became restored to areas tormented by the arcing on the Benin-Egbin 330kV isolator, which triggered line tripping and a consequent lack of supply to a few areas. but, opposite to media reviews, the incident did no longer motive a machine crumble.

This brought on tripping on the Egbin generating Station, leading to the loss of strength deliver to all of the Egbin Transmission Substation’s outgoing lines.
“This led to an exponential boom in load at the Osogbo-Ihovbor 330kV line 1, with serious arcing of isolator terminals at the Osogbo-Ihovbor 330kV line 1. To save you the series of occasions from affecting the countrywide grid, the Osogbo-Ihovbor 330kV line became opened to briefly reduce off the float of electricity on that line.
