She said, this includes the 330kV transmission lines along the Shiroro–Mando axis, major upgrades at the Jebba transmission substation, and the restoration of the second Ugwuaji–Apir 330kV transmission line.
Furthermore, she said following the submission of the investigative report on the causes of previous grid collapses, the TCN began addressing the identified weaknesses in the transmission system.
She explained that efforts are being made to close the gaps highlighted in the report and to enhance the overall stability and resilience of the grid.
“We assure the public that all necessary measures are being taken to ensure the grid’s long-term stability, in line with the recommendations of the investigative committee, while also addressing infrastructure damage such as vandalised transmission lines,” she said.
Nigerians were on Thursday morning thrown into darkness due to ‘system outage’.
