Tranny Company associated with Nigeria (TCN) has said that it had restored full power supply to the national grid at 4: 54 pm on the 9th regarding November, 2019, after the partial system collapse which occurred in 11. 15 pm on Friday, 8th November, 2019.
The company announced that during the entire period however, the nation did not experience complete loss of supply at the same time.
In a statement signed by the General Manager (Public Affairs), Mrs Ndidi Mba the particular TCN said that 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 involving the Onitsha – Alaoji transmission line on overcurrent.
“These made the main 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.
According to the exact statement, since “TCN went on to fully complete the very restoration of the Western/Northern axis, it equally began a restoration connected with supply to the Eastern axis of the main grid. When the power was nearly fully normalized, there has been a fire event at the Onitsha Substation which usually necessitated finally, the isolation with that substation, to save lives and properties.
“At this stage, because the grid had not fully stabilized, that shutting down of Onitsha substation, led to one of the tripping for some power stations connected to the grid and supply loss in the North plus Western axis.
“Through the period of any power restoration process however, some other energy stations similarly tripped while others continued to provide the main grid.
‘This means that there was no one time that the entire grid had been down simultaneously as TCN effectively utilized power from the power generating stations not directly affected by the occurrence to attempt to stabilize the power.
“TCN further noted that will what experienced been described in the actual media while a 2nd collapse does not exist as the process about restoration seemed to be still ongoing, during which often technical hitches are expected.
‘TCN expressed appreciation towards the governments and citizens from the nation for their patience while the episode lasted in addition to pledged not really to be deterred in working to be able to further strengthen the nation’s transmission grid. ”
