There was blackout across the country on Tuesday as a result of the collapse of the national grid.
The situation was caused by a fire incident on one of the pipeline systems in the country, the ministry of power said in a statement.
It identified the pipeline system as Escravos Lagos Pipeline System near Okada, Edo state.
The ministry, which also includes works and housing sectors, said it was working to restore power distribution nationwide.
The statement released on Tuesday night read: “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 Tuesday, 2nd January, 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 2nd January 2018. The national transmission grid is owned and operated by the Transmission Company of Nigeria (TCN).
“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 Ltd (NGPTC), a subsidiary of Nigerian National Petroleum Company (NNPC).
“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.”
In his New Year speech, President Muhammadu Buhari had celebrated landmarks in the power sector under his watch.
He said: “Generation has now reached 7,000MW. On December 8, 2017 the country achieved 5,155MW of power delivered to consumers, the highest level ever recorded.
“Several moribund projects have been revived. Repairs of Afam Power Station added 110MW in 2017 and another 240MW will be added this year through a private investment partnership.
“Katsina Power Project is now being tested and producing 10MW of power from wind for the first time in Nigeria. It should be fully operational this year.
“The Zungeru 700MW Hydroelectric Power Project, stalled by court cases is due for completion in 2019. The transmission and other requirements to operate the 30MW Gurara Phase 1 Hydroelectric Plant, the 40MW Kashimbilla Hydroelectric Plant and the 215 MW Kaduna Gas/LPG/Diesel Power Plant will also be completed this year.
“A landmark project, Mambilla Hydroelectric Power Project is at last taking off. This project has been on the drawing Board for 40 years, but now the engineering, procurement and construction contract for the 3,050MW project has been agreed with a Chinese joint venture Company with a financing commitment from the government of China. Completion is targeted for 2023.”
