Oil Workers’ Strike: Operator Maintains Grid Stability Amid Gas-fired Electricity Disruption

The Nigerian Independent System Operator (NISO) said it has successfully maintained stableness connected the nationalist grid contempt experiencing important procreation shortfalls triggered by concern enactment by the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN).

The strike, which disrupted cardinal operations wrong the state proviso chain, led to wide state shortages, adversely impacting the procreation capableness of gas-fired powerfulness plants crossed the country.

According to NISO, powerfulness procreation connected the National Grid fell sharply from implicit 4,300 megawatts (MW) successful the aboriginal hours of Sunday, September 28, 2025, to astir 3,200 MW astatine the lowest point, representing a important simplification successful disposable electricity.

This abrupt shortfall threatened to destabilise the grid, raising concerns astir imaginable nationwide blackouts.

In effect to this captious challenge, NISO swiftly activated an array of contingency interventions to safeguard the grid’s stability, security, and reliability.

Central to these measures was the optimisation of hydropower resources, with large hydroelectric stations expanding output by implicit 400 MW.

This strategical ramp-up provided important further capacity, cushioning the shortage caused by the faltering gas-fired powerfulness plants.

Furthermore, the System Operator implemented real-time procreation dispatch and load balancing adjustments to guarantee that proviso continuously matched request portion preventing the strategy frequence from collapsing, which could person led to wide outages.

Constant voltage and frequence enactment were besides provided done reactive powerfulness compensation and rigorous reserve monitoring to support the integrity of the powerfulness strategy nether strain.

Acknowledging the severity of the situation, NISO besides deployed demand-side absorption strategies. Selective load shedding was introduced arsenic a past edifice measurement to debar full strategy breakdown, enabling a controlled and just organisation of disposable power.

These cautiously calibrated efforts helped avert the hazard of a system-wide blackout, peculiarly protecting captious infrastructure and indispensable services.

The National Control Centre, led by NISO management, praised the timely and effectual effect that minimised disruption and ensured continuous powerfulness proviso amid unprecedented operational challenges.

The occurrence underscores NISO’s committedness to proactive grid management, operational excellence, and adherence to planetary champion practices successful energy strategy operations.

NISO reaffirmed its dedication to guaranteeing a secure, stable, and reliable energy proviso that supports economical maturation and improves lives nationwide.
