The power generation dropped to just 39 megawatts at 11 am. on Tuesday, down from 3,825 MW as an hour earlier.
Last Friday, power generation fell to zero megawatts on the grid, according to the Nigerian Independent System Operator (NISO), cutting off supply to all 11 distribution companies by 1 pm that day.
Power generation had peaked at 4,762 MW as of 6 am on Tuesday, five hours before the latest development.
In a statement on Tuesday, Eko Distribution Company informed its customers of a system collapse that resulted in power loss.
‘Kindly be informed that there was a system collapse at 10:48 hrs, which has resulted to a loss of power supply across our network.
‘We are currently working with our TCN (Transmission Company of Nigeria) partners as we hope for the speedy restoration of the grid. We will keep you updated as soon as power supply is restored.
‘Kindly bear with us’, it said.
This is the third grid collapse in less than one month after that of 29 December 2025.
As the grid collapsed on Tuesday, load allocation to the distribution companies was 0.00 MW, indicating that no distribution company was supplying electricity at the time of the incident.
NISO is yet to explain the cause of the current grid collapse.
NISO confirmed that the outage occurred at about 12:40 pm., following the simultaneous tripping of several 330kV transmission lines.
