The blackout that was experienced across Nigeria on Tuesday persisted till Wednesday after efforts by the Transmission Company of Nigeria (TCN) to restore electricity failed, following a second system collapse of transmission network at about 16 hours interval.
It was learnt that the first collapse of the power transmission grid occurred on Tuesday, January 2, 2018 at about 10.20pm, while the second happened at 2.19pm on Wednesday.
Top officials of the Transmission Company of Nigeria told newsmen that the first collapse contributed largely to the second shutdown, as the country lost about 3,000 megawatts of electricity due to the incidents.
The first grid collapse was due to a fire incident on the Escravos Lagos Pipeline System of the Nigerian Gas Processing and Transportation Company Limited.
It was gathered that the fire outbreak on the ELP, a natural gas pipeline that supplies gas from the Escravos region of the Niger Delta area to Lagos, would affect the supply of gas to three states in the South-West.
A statement Wednesday by the company’s General Manager, Public Affairs, Mrs. Ndidi Mbah, however, assured Nigerians that restoration of the grid had reached an advanced stage.
TCN added that it had also commenced investigations to determine the exact cause of the system disturbance.
“The system disturbance happened at a time when work on the Western Gas Pipeline (Ecscavos-Lagos Pipeline System) by the Nigerian Gas Processing and Transportation Company Ltd (NGPTC), which caused a system collapse at about 21.17 hours on Tuesday was yet to be completed.
“The grid would have withstood the Odukpani infraction, if generation along Lagos region was available,” said TCN in the statement.
TCN explained that NGPTC, the gas supply and marketing subsidiary of the Nigerian National Petroleum Corporation (NNPC), had indicated that a contractor had been mobilised to repair the affected segment of the Escravos-Lagos pipeline, so that gas supply to the Omotosho, Egbin, and Olorunsogo I and II thermal power stations could be restored.
“According to NGC, work would be carried out day and night and is expected to be completed within 24 hours,” TCN assured the public.
