The northern region is marking its eighth consecutive day without electricity.
The outage was triggered on Monday after the tripping off of the 330kV circuit transmission line between Benue and Enugu.
The transmission line between Shiroro and Kaduna was also affected, affecting Kano, Gombe, Kebbi, Jos, Kaduna, Benue, Bauchi, Adamawa, Taraba, Borno, Kwara, Nasarawa and Yobe.
The Transmission Company of Nigeria (TCN) has acknowledged the ongoing outage, assuring residents that they are taking “every possible measure” to restore power to the Northern region.
According to the company, the 330kV DC Ugwaji-Apir double circuit tripped due to a fault.
The latest fault in the 330kV DC transmission line occurred just days after Nigeria experienced three national grid collapses within a single week.
The TCN on Sunday said it is doing everything possible to restore power in Northern Nigeria.
The company attributed delays in restoration to infrastructure challenges worsened by vandalism and insecurity.
TCN in a statement by its spokesman, Ndidi Mbah, said it is working with the Office of the National Security Adviser to repair the vandalised Shiroro-Kaduna line that led to a reduction of bulk electricity to Kaduna, Kano and other major cities in the north.
Mbah, TCN’s General Manager of Public Affairs, said the company is confident that the bulk power supply will be restored as quickly as possible.
