The Nigerian Independent System Operator has reported a drop in electricity generation on the national grid, attributing the decline to gas supply disruptions caused by the alleged vandalism of a pipeline in the upstream network.

In a statement released on Tuesday, NISO said the incident affected gas delivery to multiple power plants.

“The Nigerian Independent System Operator (NISO) wishes to inform the general public and sector stakeholders that 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,” the statement reads.

In response to the situation, NISO stated that it promptly activated its established contingency measures to maintain the stability and reliability of the power system.

“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,” the operator said.

NISO reassured the public of its dedication to proactive grid management and strict adherence to operational standards, aiming to deliver a secure, stable, and reliable electricity supply nationwide.
