Local time September 14, many power distribution companies in Nigeria reported that they were unable to provide power to users since the early morning of the 14th due to the collapse of the national grid system. It is said that the country’s power supply dropped from an average daily 4,100 megawatts to 273 megawatts in the early morning of that day, a 93.5% reduction in power supply, causing widespread power outages across Nigeria for several hours.

From noon that day, power supply was gradually restored in many places. The Transmission Company of Nigeria (TCN) later disclosed that the accident was caused by a fire on the line and said that the national power grid had been operating stably for 421 days.

Nigeria is Africa’s major oil and natural gas producer, but the power grid is unstable, forcing households and businesses to generally purchase diesel and gasoline generators for backup.
