The nation’s power generation dropped by 1,682 megawatts on Monday from 4,129.2MW on Sunday.
Data from the Nigeria Electricity System Operator, an arm of the Transmission Company of Nigeria, showed that generation stood at 2,441MW as of 6.00 am on Monday.
Total power generation rose from zero megawatt as of 6.00 am on Friday to 3,235MW on Saturday, according to the data.
The power grid reportedly collapsed on Wednesday and Thursday last week, worsening electricity supply in many parts of the country.
The Managing Director, TCN, Usman Mohammed, described the system collapse as the worst ever since he took over the leadership of the company.
The system operator put the nation’s installed generation capacity at 12,910.40MW; available capacity at 7,652.60MW; transmission wheeling capacity at 8,100MW; and the peak generation ever attained at 5,375MW.
The nation generates most of its electricity from gas-fired power plants, while output from hydropower plants makes up about 30 per cent of the total.
