The Nigerian Independent System Operator (NISO) has explained reason behind the recent national grid failure which occurred on Wednesday.
NPO earlier Reported that the national grid had again collapsed, resulting to power outage in several parts of the country.
While the several electricity distribution companies (DisCos) had attributed the outage to the grid collapse which occurred around 11:20am, they were however unable to confirm the cause of the collapse.
NISO, in a statement issued on Wednesday afternoon, however disclosed that the national grid collapse was caused by the tripping of a Generating Company (GenCo).
This, according to the operators, resulted to a significant load drop which extended to other GenCos.
NISO disclosed embarking on immediate restoration of the grid which had seen power restored across the country.
It assured that the remote causes of the incident will soon be identifed as investigation is underway.
“The disturbance was caused by the tripping of a GenCo, resulting in a significant load drop, which cascaded to other GenCos, leading to a system disturbance.
“NISO immediately commenced restoration of the grid at 11:45 hrs, beginning with supply to Abuja from the Shiroro power plant, and substantial restoration has been achieved across the country.
“A full investigation into the immediate and remote causes is underway.
“The outcome (s) of the investigation report would determine the remedial and proactive actions to be taken to forestall future occurrences.
“We crave your indulgence to bear with us as restoration is still ongoing.” The statement partly read.
