The national grid has collapsed again, causing a nationwide outage.
The collapse happened on Monday at 10:51am with the grid crashing to zero megawatts (MW).
The development is coming weeks after electricity consumers claimed they had enjoyed improved supply.
The national electricity grid as of 10am on Monday had 3,712MW generated from 21 Generation Companies (GenCos) before it dropped to 0MW one hour after.
According to the information from the System Operations, only a section of the Transmission Company of Nigeria (TCN), Afam IV, was on the grid but with zero supply as of 12noon.
As of Sunday, the highest generation was 4,100MW while the lowest was 3,652MW with the frequency hovering between 49.04 Hertz (Hz) and 50.34Hz.
Since July 1 this year, consumers said power supply had increased in their various areas.
The Nigerian Electricity Regulatory Commission (NERC) had attributed the improvement in power supply nationwide to the partial activation of contracts that seeks to hold sector operators liable for deliberate incompetence.
The national grid collapsed twice, in July and in August but was quickly restored and power supply improvement was sustained before the latest system collapse on Monday.
According to records, this is the seventh system collapse this year, much more than the three recorded last year.
Although TCN, the national grid manager was yet to establish the cause of the crash, some insiders said it could be as a result of a maintenance of the 330 kilovolts Jos – Bauchi transmission line maintenance slated for Monday.
Some DisCos including Kaduna Electric, Enugu, and Kano, had already communicated the nationwide outage to their customers noting that efforts were ongoing to restore supply.
