The Nigerian government has announced that restoration of the national grid has commenced hours after its collapse on Tuesday, the second such incident since Friday last week.
The Nigeria Independent System Operator (NISO), in an update on Tuesday, said nationwide electricity restoration began around 11:00 a.m. following the collapse at about 10:48 a.m. the same day.
NISO clarified that the grid disturbance originated from the Gombe Transmission Substation. However, restoration began at about 11:11 a.m. and has since been completed.
“The national grid experienced a voltage disturbance which originated from the Gombe Transmission Substation.
“The disturbance rapidly propagated across the network, affecting Jebba, Kainji, and subsequently Ayede Transmission Substations. The event was accompanied by the tripping of some transmission lines and generating units, resulting in a partial system collapse.
“Appropriate corrective actions were immediately implemented to stabilise the system and restore normal operations. Restoration, which began at about 11:11 a.m., has since been completed.
“The incident only affected part of the grid; therefore, it was not a total collapse as reported.”
He added that the national grid has been fully restored and electricity supply across the affected areas has returned to normal
