Lagos, Feb.7, 2019 (NNN) The Transmission Company of Nigeria (TCN) on Thursday said it had successfully repaired and energised the 150MVA 330/132kv transformer which got burnt five years ago in Kumbotso Transmission Substation in Kano State.
Mrs Ndidi Mbah, the General Manager Public Affairs, TCN, in a statement said this was in line with the President Muhammadu Buhari-led administration’s policy on incremental power.
According to Mbah, this is the first time TCN in-house engineers are successfully undertaking such repair work on a badly burnt 150MVA capacity power transformer and restoring it to service.
“It is also an indication of the growing capacity of its engineers under the present administration.
“The Kumbotso Transmission Substation had four 150MVA power transformers. Five years ago, one of the transformers got burnt and was considered irreparable.
“On Jan.1, a second 150MVA tripped on fault with investigations revealing that its winding coil had spoilt and it had to be moved to a transformer repair factory in Lagos.
“The engineers opened the burnt transformer and removed the yellow, blue and red phases of the burnt diverter switches, replaced them and carried out other works inside the transformer before it was re-energised.
“With the successful repair of the 150MVA power transformer, the capacity of the substation has been restored to three 150MVA power transformers,” she stated.
Mbah said that the company had equally taken delivery a brand new 150MVA power transformer from Lagos Port which was currently in Lokoja en route Kombtso substation.
“TCN plans to install the transformer immediately it gets to the substation.
“The company can now supply normal bulk power to Dakata Transmission substation and Kano distribution load centres, taking supply from this substation to Katsina, Kankia and environs.
“Installation of the new 150MVA will provide the necessary redundancy in the substation,” she said.
The general manager promised that TCN would do everything possible to ensure that it continued to expand the network as well as maintain existing infrastructure in the transmission grid. (NNN)

TCN dismisses claim of free electricity to Nigerians 

Published

on

Transmission Company of Nigeria (TCN) has dismissed the claim that Federal Government was providing free electricity to Nigerians as government does not own all sections in the power sector.

The Managing Director of TCN, Mr Usman Mohammed, made this known in an interview in Abuja on Thursday.

“There is also the information that power is going to be free, that is going to affect us because some customers who get this information may not likely pay. The Federal Government cannot make power free because it does not own the power.

“Apart from the transmission (TCN) which is just the transporter of electricity that belongs to the Federal Government, all the other chains are in private hands.

“As at now that the Federal Government is providing subsidy, and that is not coming enough as we still have huge unpaid bills,” he said.

He said that electricity supply services significantly improved in the first 14 days of the lockdown across Lagos, Ogun states and Abuja.

Mohammed said that what the country need to do at this stage was to sustain electricity supply.

“That is what we are doing and in the last two weeks that we have been on lockdown, we have performed very well,” he said.

He lamented that the ongoing lockdown may affect revenue generation for the power sector.

According to the TCN boss, the company has scaled down operations to the extent that only the senior staff are working along with technical staff who run shifts.

He said that TCN was observing all preventive measures on the COVID-19 as directed by National Centre for Disease Control (NCDC).

Mohammed also commended the Federal Government for steps taken to contain the pandemic and urged Nigerians to abide by all directives of government to save lives.

The TCN boss said that the company in the first three months of 2020 made a lot of successes.

“We installed a 300 Mega Volt Amp (MVA) transformer in less than a month and this has never happened in the history of TCN.

“We also connected the protection system through fibre which we have not done before too.

“During this lockdown period, we also installed seven bulk power transformers across the network all using our TCN engineers,” he said.

The News Agency of Nigeria reports that the House of Representatives is to consider a fresh Stimulus Bill that would allow Nigerians to enjoy electricity supply for two months without any charge.

Published

on

The Transmission Company of Nigeria (TCN) says its engineers have completed repairs on its 60 Mega Volt Amp (MVA) 132/33 kilo Volt (KV) power transformers in Sokoto Transmission Substation.

Mrs Ndidi Mbah, the General Manager Public Affairs, made this known in a statement in Abuja on Tuesday.

Mbah said that the transformer developed fault on March 18 due to frequent circulation of 33kV feeder fault currents within the transformer, oil filtration.

She said that the transformer would commence operation on Thursday.

According to her, work is also ongoing on one of the 30MVA 132/33kV power transformers in the substation which was shut down by TCN to take care of transformer oil degradation and leakage.

“Consequently, TCN has been unable to supply bulk electricity from the transformers to Kaduna Disco for onward distribution to its customers,

“TCN has not been able to also supply electricity around Sokoto environ who take supply from the faulty transformers in the substation.

“As soon as the oil filtration is completed, the 60MVA power transformer will be energized.

”Work is on-going to urgently seal the oil leakage problem on the 30MVA transformer,” she said.

Mbah said that TCN sincerely regret the inconveniences caused the government and electricity customers in Sokoto State.

It also pledged to expedite ongoing works on the transformers, to ensure normal bulk supply was restored to the substation.

Low gas supply responsible for power shortage – TCN

Published

on

The Transmission Company of Nigeria (TCN) says the nation’s power sector is experiencing power supply shortage due to low gas supply.

A statement on Sunday in Lagos by Ms Ndid Mbah, General Manager, Public Affairs of the company, said the gas shortage has restrained the ability of many thermal power stations to generate optimally.

Mbah said: “The thermal power plants affected by gas supply constraint include; Sapele NIPP, Olorunsogo NIPP, Ihovbor NIPP and Azura Edo power plants which generated zero Megawatts on March 6.

“Other thermal power plants equally affected but generated at lower capacities include Egbin (Steam), Sapele (Steam), Delta (gas), Geregu (gas), Omotosho (gas), Olorusogo (gas), Geregu NIPP, Alaoji NIPP, Omotosho NIPP, Odukpani NIPP, Okpai (Gas/Steam) and Omoku (gas) power generating plants”.

She said  as a result of the prevailing gas constraints, there had been significant reduction in the quantum of power transmitted to the various distribution companies for onward supply to electricity consumers in the country.

“TCN, however discussed with the management of some of the affected power plants and many of them attributed their challenges to gas pipeline and processing maintenance being carried out by their gas suppliers.

“According to the management of some of the affected power plants, the maintenance of gas facilities are expected to last for ten days.

“Therefore, it is expected that the gas supply challenges will ease before the end of next week,” Mbah said.

Nigerians should be prepared to pay more for electricity — TCN boss

Published

on

Mr Usman Mohammed, Managing Director, Transmission Company of Nigeria (TCN) has said that consumers should be prepared to pay more for electricity in order to ensure regular power supply in the country.

The TCN boss said this on Friday in Lagos during the Groundbreaking for the Replacement of old wires on the Ikeja West-Alimosho-Ogba-Alausa-Ota Transmission Lines.

According to him, Nigerians have to be prepared to pay more for electricity because there is no relationship between poverty and payment of electricity.

“I want to tell the Nigerian public that we cannot move forward if we do not pay more for electricity.

“There is no relationship between poverty and payment for electricity.

“For the poor, give them electricity and a means of measurement and manage their cost.

“But if we don’t initiate a cost reflective tariff system and the situation continue like this, public funds would continue to sink in the sector in futility,” Muhammed said.

The TCN boss also urged the government to stop subsidizing the power sector in order to move the sector forward.

“We have to be prepared to remove government in the middle, this issue of government guaranteeing everybody won’t work.

“The facts is that contracts are not effective and government cannot continue guaranteeing the Generation Companies (GENCOs) where it already sank over N1.5 trillion.

“The expenses can only be stopped when contracts become effective through cost reflective tarrifs.

“We have to stop this government intervention and we can only stop it when contracts become effective.

“Contracts can only be effective when you have cost-reflective tariffs.

“When contracts are effective, everybody is binded by certain agreements,” he said.

According to him, Nigeria has the cheapest electricity in West Africa and we can’t say we are the poorest.

“Even Burkina Faso is having collection efficiency of 98 per cent, despite their location within the sub region, we therefore have to  solve the problem of market issues,” said the TCN boss.

Mohammed said that the issue of load rejection by Discos could also be resolved once bilateral contracts were effective.

Speaking on the cable replacement project, the TCN boss said that the power transmission lines were built many years ago with limitations on the quantity of electricity they were carrying, making the upgrade inevitable.

“So, we are in the process of replacement of old wires on the Ikeja West-Alimosho-Ogba-Alausa-Ota transmission lines.

“Due to the current management quest of improving availability of electricity in the country, there have been series of transformer installations across the country, and there is need for a line that can supply power to all the transformers.

“This installation will increase the current capacity of this station to about two and half capacity compared to the old capacity of 200mw.

“The line to be re-conducted has 664MW capacity of transformer, and the current line has only 200MW of capacity, so the re-conducting would increase the capacity by 2.5 per cent which would upgrade it to 500MW.

“That means all transformers the line Ikeja West is covering between Abeokuta and Lagos will be energised.

“The project would improve power supply to residents under Ikeja Electric  network,” he said.

Mohammed said that the timeframe for the reconstruction of the line was six months, adding that re-conducting was also taking place at other locations such as the line from Alagbon transmission to Ikorodu down to Maryland, among others.

The TCN boss said that being the largest TCN Sub Station in Nigeria, there were likely to be outages along the network connected to the transmission line.

IBEDC pleads with customers over TCN-Ayede fire outbreak

Published

on

The management of Ibadan Electricity Distribution Company (IBEDC) has pleaded for understanding and patience of its customers in Ibadan, Ijebu-ode, Sagamu, Iseyin, Ejigbo and parts of Ede, currently experiencing minimal supply of power.

The company’s acting Chief Technical Officer, Mr Felix Abiodun, made the pleal in a statement on Friday.

Abiodun said the poor supply was the aftermath of the TCN-Ayede Sub-station fire incident that happened on Jan. 5.

“The fire destroyed the TCN 150 MVA 330/132/33 kV power transformer that cannot be easily replaced.

“Shortly after the bulk restoration of supply, one of the remaining three transformers (3x150MVA) gave a caution sign, which led to its shut down and eventual oil filtration.

“Few days later, another transformer began tripping spuriously; the cause of this is traced to the effect of the fire and associated heat on the control cables linking the transformers,” he said.

Abiodun said the only way TCN could supply power to IBEDC’s numerous customers was through load shedding and rationing of power supply for now.

He assured the customers that TCN and IBEDC engineers were working round the clock to ensure better supply of power to the affected areas in the shortest possible time.
