The Nigerian Independent System Operator (NISO) has stated that electricity generation on the National Grid has dropped to 3,200 megawatts (MW) due to the industrial action by the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN).
A statement by NISO said the disruptions by PENGASSAN triggered widespread gas shortages, reducing available generation from over 4,300 MW.
It, however, said it has deployed contingency measures to preserve the stability, security, and reliability of the National Grid through strategic ramp-ups from major hydro stations, contributing over 400 MW of additional output to cushion the shortfall from gas-fired plants.
The statement reads, “There are now real-time load adjustments to match available generation with system demand, while preventing a system frequency collapse. While continuous deployment of reactive power compensation and reserve monitoring to safeguard system integrity is strengthened.
“There is selective load shedding, applied as a last resort, to avert a system-wide collapse and ensure fair power distribution. These timely actions enabled the NISO NCC to minimize the impact of the labour-induced gas shortages, sustain operational security, and maintain supply to critical loads, thereby averting a nationwide blackout.”
The agency assured its commitment to proactive grid management, operational excellence, and the application of best-in-class practices to guarantee a secure and reliable electricity supply for the nation.
