National Grid: NISO Confirms Power Restoration
The Nigerian Independent System Operator, NISO, has said it has fully restored power supply to all parts of the country, and system stability normalised.after a system disturbance.
The management of NISO made this known in a statement in Abuja on Monday.
According to NISO, investigations into the cause and sequence of events leading to the system disturbance are currently ongoing.
It added that appropriate measures shall be put in place to forestall future reoccurrence of such major system incidents.
“We wish to inform the general public and relevant stakeholders that the national grid experienced a system disturbance at 2.01pm. on Monday, that led to a partial collapse.
”It would be recalled that the Lagos–Escravos-Lagos gas pipeline was vandalised on December 10 , which led to the shortage in power generation in the country.
”This has further led to the fragility and weakness of the national grid,” it said.
The system operator said that preliminary reports indicated that the disturbance involved the tripping of several generating units and critical 330 Kilo Volt (KV,) transmission lines.
It said that the disturbance resulted in a widespread impact on electricity supply across parts of the country.
”However, the Delta generation complex successfully operated on island mode at the 132kV sub-transmission voltage level.
”This enabled the continued supply of electricity to Oghara, Amukpe, Benin, and Efunrun 132kV substations, with a total generation of 114 megawatts from four units at the Delta Thermal Power Station,” it added.
According to NISO, in line with established operational procedures, it promptly initiated system response measures using its dispatch and monitoring tools at the National Control Centre, NCC, Osogbo.
The system operator, however, reassured Nigerians of its continued commitment to proactive grid management, and the application of best operational practices to ensure the stability and reliability of the national grid.
