Federal Government, through the Transmission Company of Nigeria, says it would investigate the cause of the multiple power grid collapses that occurred on Monday and Tuesday.
TCN said the national grid experienced what it called a partial disturbance on Monday, saying efforts to fully recover the grid were still ongoing as of Tuesday.
However, the Minister of Power, Adebayo Adelabu, said there was nothing like a grid collapse but a trip-off.
TCN spokesperson, Ndidi Mbah, explained in a statement that although the recovery of the grid commenced immediately, with Azura power station providing the blackstart, grid recovery reached advanced stages at about 10.24 am on Tuesday when it encountered a challenge that caused a slight setback in the recovery process.
Business Hallmark reports that the power grid collapsed again on Tuesday amid restoration efforts.
“The slight setback notwithstanding, TCN continued with the grid recovery process, which has reached an advanced stage, ensuring bulk power availability to about 90 per cent of its substations nationwide. Supply has been restored to the Abuja axis and other major distribution load centres nationwide,” she disclosed, even as many areas were still in darkness as of 7 pm on Tuesday.
Mbah explained that the partial disturbance did not affect the Ibom Gas generating station, which was islanded from the grid yesterday, and continued to supply areas in the South Southern part of the country such as Eket, Ekim, Uyo, and Itu 132kV transmission Substations during the period.
“Investigation into the cause of the incident will be carried out as soon as the grid is fully restored,” she noted.
