Power supply to parts of Lagos is expected to improve after the Transmission Company of Nigeria (TCN) restored the Benin–Egbin 330kV transmission line following a major grid disturbance that disrupted electricity across the Lagos corridor on Thursday.
The incident, which occurred at about 8:19 a.m., triggered voltage instability on the national grid, forcing some generating stations offline and causing outages on key transmission lines supplying electricity to Lagos and neighbouring communities.
To prevent a wider collapse of the grid, the National Control Centre directed several electricity generation companies to reduce their output, a move aimed at stabilising system frequency and containing the disturbance.
Efforts to restore normal supply received high-level government attention as the Minister of Power, Chief Joseph Tegbe, convened an emergency meeting with the leadership of the Transmission Company of Nigeria and the Nigerian Independent System Operator (NISO) to coordinate recovery operations.
In a press statement issued on Thursday by the General Manager, Public Affairs, Ndidi Mbah, TCN confirmed that the Benin–Egbin 330kV transmission line has been successfully returned to service and is once again wheeling bulk electricity to the Lagos complex.
The company, however, said engineers drawn from its Benin and Omotoso sub-regions are still working to repair faults on the Benin–Omotoso 330kV transmission line, describing the exercise as critical to the full restoration of electricity supply to the affected areas.
TCN apologised to residents and businesses affected by the disruption, assuring consumers that every available resource is being deployed to restore normal power transmission as quickly as possible.
The company also reaffirmed its commitment to improving grid stability and strengthening the transmission network to reduce the likelihood of similar incidents in the future, while promising to keep the public updated on the progress of restoration works.
