The Transmission Company} of Nigeria, TCN, said it had restored full electricity supply to the national grid 18 hours right after partial system collapse.
The particular system collapse which occurred at exactly 11. 15 pm on Friday, 8th November 2019, was fully restored at 4: 54 pm on the 9th of November, 2019.
According to the company}, during the entire period however , the particular nation did not experience complete loss associated with electricity provide at the same time.
In a statement signed by the General Manager (Public Affairs), Ndidi Mbah, the incident was caused by the tripping of typically the Lokoja – Gwagwalada transmission lines 1& 2 upon power swing, due to causes yet in order to be determined, and this tripping regarding the Onitsha – Alaoji transmission line on overcurrent.
“These made the grid to operate in two parts, with the second part which is the Western and Northern axis experiencing an outage. Efforts immediately commenced to bring the Traditional western and North axis back into the circuit, and as soon because that was almost complete, meaning supply was available most of often the areas, your Eastern axis went out. ”
The declaration further stated that TCN went on to be able to fully complete the restoration of the exact Western/Northern axis, it equally began the very restoration involving supply for you to the Eastern axis of the grid.
“When the main grid was nearly fully normalised, there has been a fire event at the Onitsha Substation which necessitated a isolation connected with that substation, to save lives and properties.
“At this stage, because the power had not completely stabilized, the main shutting down of Onitsha substation, led to finally, the tripping with some power stations connected to the grid and supply loss in the North plus Western axis.
“Through the period of that power repair process however, some other energy stations similarly tripped while others continued to source the grid. This means that there was no one time that the entire main grid was straight down at one of the same time as TCN effectively utilised power from the strength generating stations not directly affected by any incident to help attempt towards stabilize the actual grid, ” the assertion added.
