Nigeria may face a nationwide blackout starting Monday as power generation companies (GenCos) warn of an imminent shutdown of thermal power plants following directives from the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN).

The Executive Secretary of the Association of Power Generating Companies (APGC), Joy Ogaji, confirmed the development in a WhatsApp message on Sunday, September 28, 2025. She disclosed that gas suppliers had already issued notices to halt supply to thermal stations in line with PENGASSAN’s nationwide strike order.

• “Good day, all. Thermal GenCos have received notification from our gas suppliers to shut down our thermal power plants following directives from PENGASSAN. The Nigerian Gas Infrastructure Company has specifically requested GenCos to comply,” Ogaji revealed.

She cautioned that the move could plunge the entire country into darkness, warning that Nigeria’s hydroelectric dams alone cannot sustain the national electricity grid.

“Please all be notified of the imminent darkness, as hydros alone cannot sustain the system,” she added.

This alarming update comes just hours after PENGASSAN announced a total nationwide strike to protest the dismissal of more than 800 Nigerian workers at the Dangote Petroleum Refinery. The union, after an emergency National Executive Council (NEC) meeting on Saturday, directed all members in oil and gas installations to withdraw their services until the sacked staff are reinstated.

Industry experts warn that the strike could paralyze Nigeria’s oil and gas sector, disrupt crude production, halt fuel supply, cut gas distribution, and cripple electricity generation. With thermal plants responsible for over 70% of the nation’s power supply, the shutdown risks widespread blackouts, overstretching hydro plants, and pushing the country toward a possible total system collapse.
