ABUJA—POWER supply in Nigeria has dropped, as the Transmission Company of Nigeria, TCN and Nigerian National Petroleum Corporation, NNPC, record system collapse and pipeline shutdown respectively.
TCN disclosed in a statement that: ‘’TCN regrets to report another System Collapse at about 14.19 hours today January 3, 2018. Preliminary information from NCC indicated that the tripping of Odukpani-Ikot Ekpene 330kV line cut off generation from Odukpani Power Station to the grid. Restoration of the grid has reached advanced stage. TCN has also commenced investigations to determine the exact cause of the system disturbance and the outcome will publicised.
‘’The system disturbance happened at a time when work on the Western Gas Pipeline by NGC which caused system collapse at about 21.17Hours yesterday, is yet to be completed. The grid would have withstood the Odukpani infraction, if generation along Lagos Region were available.”
‘’NGC indicated that a contractor has been mobilised to reconstruct the affected segment of the Western Gas Pipeline, so that gas supply to Omotosho, Egbin, and Olorunsogo I and II can be restored. According to NGC the work would be carried out day and night and is expected to be completed within 24 hours.
‘’TCN noted that with the support of the Federal Ministries of Power and Finance, it has embarked on the implementation of Transmission Rehabilitation and Expansion Program that seeks to expand, rehabilitate and stabilize the Grid. TCN appealed for patience and understanding.”
NNPC shuts down gas pipeline in S-West
Also, the Nigerian National Petroleum Corporation, NNPC, yesterday, warned of power outage in some states in the South-West, mainly in Lagos, Ogun, Ondo states following the shutdown of its gas pipeline for maintenance.
The NNPC, in a statement in Abuja, by its Group General Manager, Group Public Affairs Division, Mr. Ndu Ughamadu, said that the outage will be as a result of plan to completely shut down the Escravos to Lagos Pipeline, ELP, to enable it extinguish the fire which engulfed the pipeline and repair the pipeline.
It said the shutdown of the pipeline will affect gas supply to customers in the three listed states, leading to the shutdown of a number of power plants in the states, with a combined capacity of 1,143 megawatts, MW, of electricity, effectively ensuring that the three states suffer a drop in electricity supply until the repair is completed.
Ughamadu said that the Group Managing Director of the NNPC, Mr. Maikanti Baru, had ordered an immediate assessment of the damage caused by the fire on the ELP, a natural gas pipeline which supplies gas from Escravos region of the Niger Delta area to Lagos.
He said, “NNPC firemen were drafted to the scene and were able to contain the fire from the leak point of the pipeline incident. However, the fire could not be extinguished due to the high pressure of the line.
“To put out the fire, the line will require being isolated and depressurised, which might lead to a complete shutdown of the pipeline segment for repair works to be carried out. The exercise will affect gas supply to customers in Ondo, Ogun and Lagos State with subsequent shutdown of the following power plants with a combined generating capacity of 1,143 megwatts, MW: Egbin, Lagos, Olorunshogo, PEL Olorunshogo, Ogun, Paras Power Plant, Ogun and Omotosho plant, Ondo State.”
He noted that the pipeline also supplies gas to power plants in the South West, in addition to feeding the West Africa Gas Pipeline System.
According to Ughamadu, the incineration of the ELP, which was built in 1989, was suspected to have been caused by a bush fire, January 2, 2018 at Abakila, in Ondo State.
3,182MW lost to fire
Meanwhile, the Ministry of Power disclosed in a statement that Nigeria’s power sector lost 3,182 megawatts, MW, as a result of a fire incident on the Escravos-Lagos Pipeline System which is close to Okada, Edo State.
It stated that the fire incident required a shutdown of the pipeline supplying gas to Egbin, 1,320MW; Olorunsogo NIPP, 676MW; Olorunsogo, 338MW; Omotosho NIPP, 450MW; Omotosho, 338 MW; and Paras, 60MW on Tuesday.
It said that the sudden loss of generation due to interruption in gas supply from these stations caused the national transmission grid to trip off around 8:20p.m., on Tuesday.
“Regrettably, after a sustained period of increasing production and distribution of power since September 2017 to date, the Nigerian Gas Processing and Transportation Company Ltd, NGPTC, has reported a fire incident on its Escravos Lagos Pipeline System near Okada, Edo State on January 2, 2018
‘’The incident requires a shutdown of the pipeline supplying gas to Egbin 1,320MW; Olorunsogo NIPP 676MW, Olorunsogo 338MW, Omotosho NIPP 450MW, Omotosho 338 MW and Paras 60MW power stations.
“The sudden loss of generation due to interruption in gas supply from these stations caused the national transmission grid to trip off around 20:20 on January 2, 2018. The national transmission grid is owned and operated by the Transmission Company of Nigeria.
“Most of Nigeria’s power generation is from thermal power stations that require gas for fuel. The gas is produced by oil and gas companies overseen by the Ministry of Petroleum Resources. The gas is delivered to the power stations through pipelines owned and operated by Nigerian Gas Processing and Transportation Company Limited, a subsidiary of Nigerian National Petroleum Company.
“TCN and the generation companies are working to restore operation of the national grid. Once the national grid is restored output from the hydroelectric power stations and all other unaffected gas fired thermal power stations will be increased to the extent possible to minimize the impact of loss of generation from the affected power stations while NNPC takes necessary steps to restore gas supply.
“We urge members of the public to bear with us as we work to overcome this set back which should be temporary.”
