NISO Attributes Generation Drop to Gas Supply Shortage

December 17, 2025

The Nigerian Independent System Operator (NISO) has informed the general public and sector stakeholders that the electricity generation on the National Grid dropped due to gas supply constraints arising from the incident of gas pipeline vandalization within the upstream gas supply network.  Saying that the incident affected gas availability to a number of power generation facilities.

According to NISO’s statement, 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 generation, 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 operations.

“NISO wishes to assure the public of its commitment to proactive grid management and the application for appropriate operational standard to ensure a secure, stable, and reliable electricity supply nationwide.
