The nation’s power grid has suffered a total collapse for the first time in three months, latest data from the Ministry of Power, Works and Housing have shown. The grid collapsed on December 21, increasing the number of collapses recorded so far this year to 12 – one was partial while the rest were total. The total collapses occurred in January (five), February (one), June (one), July (one), September (two) and December (one), while one partial collapse was recorded in April. According to the Nigerian Electricity Regulatory Commission, a total system collapse means total blackout nationwide, while partial system collapse is a failure of a section of the grid.
Total power generation stood at 4,214.30 megawatts as of 6 pm on Monday, December 24, down from 4,402.20MW on Sunday. Six power plants, namely Sapele I, Alaoji NIPP, Olorunsog NIPP, Odukpani NIPP, AES and ASCO, did not generate any megawatts on Monday. Total generation capacity of 626.4MW was unutilised on Monday, as a result of low demand by electricity distribution companies.
The Nigeria Electricity System Operator, an arm of the Transmission Company of Nigeria, put the nation’s installed generation capacity at 11,165.40MW; available capacity at 7,139.60MW; current transmission capacity at 7,000MW; network operational capacity at 5,500MW, and the peak generation ever attained at 5,222.3MW. The nation generates most of its electricity from gas-fired power plants, while the output from hydropower plants makes up about 30 per cent of the total. NERC, in its latest quarterly report, said the power sector recorded a significant improvement in the stability of the grid network during the second quarter of this year. According to the report, the improvement in the grid stability achieved in the quarter was attributed to the commission’s and TCN’s commitment to ensuring stable electricity supply.
