Blackout: Nigeria’s national grid collapses
Blackout: Nigeria’s national grid collapses

ON SEPTEMBER 29, 201710:58 PMIN NEWSCOMMENTS

The Transmission Company of Nigeria (TCN) said a total system collapse of the national grid was recorded on Sept. 28 at 8:03 p.m., resulting in temporary loss of electricity generation for the nation’s power grid.

A statement from TCN’s management on Friday in Abuja said that reports obtained from power stations and the sequence of events generated by the Supervisory Control and Data Acquisition (SCADA) had revealed the cause of the collapse.

It said the SCADA system report indicated that the system collapse was triggered by the tripping of Egbin power plants Units ST4, ST6 and ST5.

It, however, said that restoration of grid system had also commenced at 8:22 p.m. on Sept. 28.

According to the statement, a post mortem analysis of the issue indicated that grid generation was curtailed to about 4,262.7 Mega Watts (MW) before the disturbance.

It explained that the capacity under-utilisation and the operational capability required to maintain grid stability, which had waned, made the grid system vulnerable.

It said the vulnerability and disturbance of the system resulted in severe system frequency dip that culminated in the system collapse.

It further revealed that the analysis conducted clearly showed that there was insufficient level of rotating reserve provided by grid-connected generation companies arising from low tariffs for providing ancillary services.

It said TCN had filed an application to the Nigerian Electricity Regulatory Commission (NERC) for an extraordinary tariff review to avert further occurrence of such incident.

It said the proposal for a tariff review would ensure that Generation Companies (GENCOS) were given the necessary incentives to provide sufficient spinning reserves and other ancillary services critical for managing the national grid.

“TCN hereby solicits for the understanding of all Nigerians as it continues with efforts to provide the electricity industry with a world class national grid.

“It will strive to ensure that the stride attained recently in frequency control is sustained in line with world industry standards and codes,“ the statement further stated.

fashola once said electricity generation is not rocket science.. Lol lawyer telling engineers what to do. Misplaced priority

The grid went down for 30mins n una no allow person hear word?!

Truly, he hasnt been exceptional(yet), but did d so called engineers perform any better?

So you now think a Lawyer will outperform an engineer in his own field??... well ion blame you sha... na d mumu COREN cause all these...

U seriously are a joker!? How many engineers run all these tech/oil n gas coys?

We need results not certificate!

Without Engineers those coys etc won't go far... that's why I blame COREN.... so you think Nigerian engineers are only about certificate??

Nope!

Just that, we dont need phcn to be headed by an engineer to make it successful.

Pple like Barth Nnaji(engineer cum administrator) are not common!

No electricity in Abuja for the past 48hrs
