The Transmission Company of Nigeria (TCN) said on Tuesday efforts to fully repair the national grid are almost complete following a partial disturbance on Monday.
The power grid collapsed at 7:00 p.m., on Monday, prompting immediate recovery efforts.
The national grid collapsed again on Tuesday to throw the country into a complete blackout.
The system collapse was also the fifth this year.
The TCN’s General Manager for Public Affairs, Mrs. Ndidi Mbah, said in a statement on Tuesday the recovery process commenced swiftly with Azura Power Station providing the necessary “blackstart.”
She added that by 10:24 a.m. on Tuesday, the grid recovery had reached advanced stages despite encountering a brief challenge that caused a minor setback.
The GM said: “Notwithstanding the setback, TCN continued its recovery efforts, achieving significant progress.
“Bulk power availability has been restored to approximately 90 percent of its substations nationwide, with supply reinstated to the Abuja axis and other major distribution load centres.
“The partial disturbance did not affect the Ibom Gas generating station, which continued to supply power to areas in the South-South part of the country, including Eket, Ekim, Uyo, and Itu 132 kilovolt transmission substations.”
