AEDC tackles TCN over load dropping allegation

By Chris Ochayi
The management of Abuja Electricity Distribution Company, AEDC, yesterday, described allegation of load rejection in Kogi state raised against it by the Transmission Company of Nigeria, TCN, as untrue, unfounded and unfortunate.

The AEDC, while rejecting the allegation, explained that the recent outage in Lokoja and environs which lingered for about 72 hours resulted from a planned maintenance work, by TCN, which was scheduled to start and end on Friday, 23rd of February, 2018, but had to be extended to the evening of Monday, February 26, 2018.

Head of Corporate Communications, Oyebode Fadipe, AEDC, said in a stsment in Abuja that, “The TCN had duly notified our Area Office in Lokoja that it was carrying out a maintenance work on its 150MVA transformer at the 330/132 transmission station in Lokoja on Friday, February 23, 2018.

According to the statement, “Our attention has been drawn to a statement issued on Monday by the Transmission Company of Nigeria (TCN), in which it alleged that excessive dropping of load by our company was responsible for the shattering of its equipment and the subsequent 72-hour outage which occurred in Lokoja, the Kogi State capital from Friday, 23rd February, 2018 to Monday, 26th February, 2018.

“We wish to state categorically that this allegation by the TCN is not only untrue and unfounded, but also unfortunate, especially coming at a time when all stakeholders in the Nigerian Electricity Supply Industry (NESI) are joining hands to ensure sustainable improvement in power supply across the country.

“For the records, AEDC hereby states that it neither drops load in its Lokoja network nor any other part of its operational area, which comprises the Federal Capital Territory (FCT), Kogi, Nasarawa and Niger states, stressing that it has in fact been yearning for more electricity allocation to enable it meet the demands of its customers.”

“The TCN had duly notified our Area Office in Lokoja that it was carrying out a maintenance work on its 150MVA transformer at the 330/132 transmission station in Lokoja on Friday, February 23, 2018, but we later got to know that the maintenance had been extended beyond that day, and by Sunday, February 25, 2018, it was all too obvious again that TCN could not conclude its upkeep on the transformer, forcing yet another extension to Monday, February 26, 2018”.

“It said further that: “It is rather unfortunate that the TCN will also turn round to blame the lingering outage in Lokoja on AEDC, when the actual reason for the outage was quite obvious”.

“Commenting further on the allegations, AEDC said the TCN’s statement implies insufficient resilience in the transmission system especially when the small load of Lokoja is considered relative to the entire load on the transmission network.

“Assuming the TCN’s allegation was correct, the implication is that every time a load was dropped due to faults and other causes a TCN equipment will be blown up because of the high voltage”. The distribution company said that: “Root cause analysis approach backed by system simulations is what should be used to inform causes of failures on the system”.

“While reiterating its concern about the TCN’s allegation, the AEDC concluded by appealing to all stakeholders in the NESI against buck passing, saying that “we should all work towards building on the successes that have been recorded so far in the power sector, in order to win greater public confidence in our capacity to turnaround the sector”.
