The ministry of Power has identified vandalism on a transmission tower as the immediate cause of the national blackout.

The ministry in a statement Saturday evening said the attack on the Odukpani Ikot Ekpene 330kV double circuit transmission line resulted in a sudden loss of about 400MW of generation.

It added that the incident thereafter led to a cascade of plant shut down across the country.

The ministry however assured Nigerians that the power on the grid is being restored sequentially by the System Operator as other on-grid power plants are being dispatched to cover the lost generation capacity from the Calabar power plant owned by the Niger Power Holding Company Ltd.

This consequently led to a cascade of plant shut down across the country.

We wish to notify the public that power on the grid is being restored sequentially by the System Operator as other on-grid power plants are being dispatched to cover the lost generation capacity from the Calabar power plant owned by the Niger Power Holding Company Ltd.
