The Transmission Company of Nigeria (TCN) has said the blackout affecting parts of Northern Nigeria will persist due to security challenges hindering repairs on critical transmission lines.

 

Despite efforts to restore electricity through alternative means, the TCN said the situation will not be fully resolved anytime soon.

 

The ongoing blackout, which has lasted over four days, initially stemmed from vandalism of the Shiroro-Mando transmission line, which provided bulk electricity to the northern states.

 

Engr. Nafisatu Asabe Ali, Executive Director of the Independent System Operator at TCN, explained during a public hearing by the Nigerian Electricity Regulatory Commission (NERC) that the repair of the Ugwuaji-Apir line would only provide limited solution.

 

She noted that while the line could carry up to 750 megawatts (MW) of power, only 350 MW could be safely transmitted to Kano, Kaduna, and parts of Niger Republic due to voltage stability issues in Kano.

 

The larger Shiroro-Mando transmission line, which supplies more power, remains out of service due to insecurity in the area where it was damaged.

 

Engr. Nafisatu said the TCN had received security advice from the Office of the National Security Adviser (NSA) indicating that the area where three towers were destroyed are currently inaccessible due to ongoing security issues.

 

Despite having the materials needed for repairs, TCN cannot proceed until the security situation improves, she noted.
