NISO restores national grid after multiple trippings on 330kV transmission network

Spread the wordThe Nigerian Independent System Operator (NISO) has announced the restoration of normal operations on the national grid following multiple trippings on the 330-kilovolt (kV) transmission network on Monday.

The system operator said the incident occurred at approximately 12:40 p.m., prompting the immediate implementation of corrective measures to stabilise the power system and restore normal operations.

In a statement published on its verified X handle, NISO assured Nigerians that restoration efforts had been successfully completed and that the national grid had returned to normal operation.

The development comes amid concerns over the stability of Nigeria’s electricity transmission system, with disruptions to the national grid capable of affecting electricity supply to homes, businesses and industries.

Corrective measures implemented to stabilise grid

NISO said its management and technical teams responded promptly to the incident by implementing appropriate corrective measures aimed at stabilising the electricity transmission network.

According to the operator, the interventions were necessary to restore normal operations following the multiple trippings recorded on the 330kV transmission network.

“NISO wishes to inform the public that at approximately 12:40 p.m. on Monday, the grid experienced multiple trippings on the 330 kilovolt (kV) transmission network,” the statement said.

The agency added that it immediately implemented the necessary measures to stabilise the power system and restore normal operations.

It subsequently confirmed that the restoration process had been completed successfully, with the national grid returning to normal operation.

The system operator also clarified the extent of the incident, saying it affected only a section of the national grid.

It warned against reports and claims circulating in the media that could create the impression that the entire electricity network had been affected.

“NISO wishes to clarify that the incident affected only a section of the grid, contrary to unverified reports and claims currently circulating in the media,” it said.

The clarification was aimed at addressing public concerns and distinguishing verified information from unconfirmed reports about the incident.

NISO urged Nigerians to exercise caution when receiving or sharing information about the state of the national grid, particularly where such reports had not been confirmed through official channels.

The agency advised members of the public to disregard misleading information and rely on its official communication platforms for accurate and verified updates on the status of the national grid.

It stressed the importance of obtaining reliable information about developments affecting the electricity transmission system.

NISO further reaffirmed its commitment to maintaining grid stability and ensuring the reliable operation of Nigeria’s national electricity transmission network.

The operator also pledged to continue providing timely and accurate information to the public regarding incidents affecting the grid.

Although NISO confirmed that normal operations had resumed, its statement did not provide further details about the specific causes of the multiple trippings or identify the affected sections of the 330kV transmission network.

The incident underscores the importance of effective grid management, rapid technical intervention and transparent communication in maintaining the stability of Nigeria’s electricity transmission system.
