The Nigerian Independent System Operator (NISO) has announced a decline in electricity generation on the national grid, attributing the drop to gas supply constraints caused by a reported incident of gas pipeline vandalism within the upstream gas supply network.
In a statement issued on Tuesday, NISO said the incident disrupted gas availability to several power generation facilities, leading to low output at a number of gas-fired power stations and a consequent reduction in available generation capacity on the national grid.
The system operator said it promptly activated established contingency measures to maintain grid stability and reliability following the development.
According to NISO, the measures include increased dispatch from available hydroelectric power stations, continuous generation re-dispatch, voltage control interventions and other operational actions required 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 operator stated.
NISO noted that the incident underscores the importance of coordinated efforts to address gas supply disruptions, particularly as the country approaches the festive season, a period traditionally sensitive for grid operations.
The operator assured that it would continue to engage relevant industry players to minimise disruptions and ensure the stability of electricity supply nationwide.
