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.

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.

APC has been the biggest mistake of Nigerians in recent memory.

It is a wonder they voted to bring this plague upon themselves.

Excuse to increase useless tariff
Useless IKEDC

Let's forget our brains in the toilet and blame Buhari, blaming Buhari is not blame game at all, it's patriotism especially since it's Buhari that sold NEPA to family and friends in the last minute

. We argued privatizing NEPA was fraud and the objective was bailout funds, this stupid Buhari administration has provided bailout twice to PHCN let's not forget PHCN has its allocation and they never stopped bold, audacious and wicked senseless billings they make money from


Yes again let's blame Buhari

gists:

Thank you jare.
This is the best comment so far today.
Of course we have to blame Buhari that and praise Jonathan that sold phcn to croonies.

But, I hope this is not a pretext to increase tariff.

Nemesis1:



If it is then we should protest, I've paid for their stupid meter over 5 months I'm yet to receive it, they won't even change my direct connection charges from 7k to 2k as stipulated by their own rules, I admit power is a bit stable where I stay but seriously? More charges?


This calls for occupy DISCOS all over again, let them provide meter, find and resolve their problems and be fair to Nigerians

DutchBruh:

They Discos where all sold to corrupt politicians by Goodluck Jonathan who know nothing about power generation. Experts have been telling the cluesless an incompetent APC to reverse the sale and give it to competent power generator companies like General Electric but they refused.

Its still far better than under jonathan unless you want to lie

SHTFguy:



Propaganda days are over.

You can continue deceiving yourself


If power supply is better under this administration, then what of the naira? I guess it is trading nearly equal to the dollar. How about the cost of daily necessities and food? Are the prices of these not double or in some cases three times what they cost prior to this govt?

As I said you can keep believing your silly propaganda.

ProWalker:


We are discussing power supply.
If you want Naira to have a respecful place among world currencies, ibos should stop their unbridled penchant for importation
