Following nationwide strike directives from the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN), Nigerians may face a nationwide blackout from Monday.

Naijaonpoint reports that this is coming after power generation companies raised the alarm over an imminent shutdown of thermal plants.

The alarm was raised on Sunday by the Executive Secretary of the Association of Power Generating Companies, Joy Ogaji, in a WhatsApp message.

According to The PUNCH, Ogaji revealed that gas suppliers had issued notices to halt supply to thermal power stations in line with PENGASSAN’s strike resolution.

She said: “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.”

According to her, the development could lead to nationwide blackout, as hydroelectric dams alone cannot sustain the national grid.

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

Recall that PENGASSAN had on Saturday night declared a nationwide strike.

In a statement following the Association’s National Executive Council (NEC), PENGASSAN instructed all its members in various offices, companies, institutions, and agencies to cease all services starting at 12:01 AM on Monday, September 29, 2025.

The union also directed all members stationed in various field locations to cease their duties starting at 6:00 a.m. on Sunday, September 28, 2025, and begin a round-the-clock prayer vigil.

According to PENGASSAN, the prayer is a call to God to make those in authority to rein in Dangote and his co-travelers on the need to obey Nigeria’s law.

It stated that during the strike period, no intervention whatsoever would be entertained across field locations except where the safety of personnel and assets is at risk, adding that such clearance must be obtained from the National Secretariat.

The action could cripple crude production, fuel supply, gas distribution and now electricity generation, worsening the hardship faced by Nigerians.

Thermal stations account for more than 70 per cent of Nigeria’s electricity supply.
