Blackout Looms as National Grid Output Falls Massively Amid PENGASSAN Strike
Nigeria’s electricity generation has dropped to 3,200MW after PENGASSAN’s strike disrupted gas supply.
NISO said hydro plants and system safeguards are cushioning the impact to prevent nationwide blackout.
The Nigerian Independent System Operator (NISO) has disclosed that electricity generation on the national grid has fallen to 3,200 megawatts (MW) due to the ongoing strike by the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN).
NISO explained that the industrial action disrupted gas supply to power plants, reducing available generation from over 4,300MW. To stabilize the grid, the agency said it activated contingency measures, including ramping up output from major hydro stations, which contributed an additional 400MW to offset the shortfall from gas-powered facilities.
The operator noted that real-time load management is being carried out to maintain balance between supply and demand. It added that system protection measures, such as reactive power support and reserve monitoring, are also in place to safeguard the grid.
According to the agency, selective load shedding is only considered as a last resort, aimed at preventing a nationwide collapse and ensuring fair distribution of electricity.
NISO emphasized that these interventions have helped cushion the impact of the strike, keep critical services powered, and avert a total blackout. The agency further reiterated its commitment to proactive grid management and steady electricity delivery nationwide.
