NISO Explains Why Electricity Generation On National Grid Dropped, How It Prevented Grid Collapse

The Nigerian Independent System Operator (NISO) has disclosed that gas pipeline vandalisation disrupted gas supply to a number of power Generation Companies (GenCos) resulting to reduction in electricity generation to the national grid.

NISO explained that following the incident, several gas-fired power stations recorded low output, which resulted in reduced available generation capacity on the National Grid.

These were disclosed in a statement by NISO management informing stakeholders of the incident and subsequent remedial measures taken to prevent national grid collapse.

According to the statement, “Electricity generation on the National Grid has dropped due to gas supply constraints arising from the reported incident of gas pipeline vandalization within the upstream gas supply network.

” The incident affected gas availability to a number of power generation facilities.

“Consequently, several gas-fired power stations recorded low output, which resulted in reduced available generation capacity on the National Grid.

” In response to the development, NISO promptly activated established contingency measures to maintain system stability and reliability. These measures included increased dispatch from available hydroelectric power stations, continuous generation re-dispatch, voltage control interventions, and other necessary operational actions to balance electricity supply with system demand.

“We are closely monitoring grid conditions, including system frequency and voltage profiles, while working with relevant stakeholders to mitigate the impact of the gas supply constraints.

“The situation highlights the importance of coordinated efforts to address gas supply disruptions, particularly as we approach the festive season, which is traditionally sensitive for grid operations.”

NISO  assured the public of its commitment to proactive grid management and the application of appropriate operational standards to ensure a secure, stable, and reliable electricity supply nationwide.
