Nigeria could face widespread power outages from September 29, 2025, as gas suppliers prepare to halt fuel deliveries to thermal power plants.
The disruption follows an industrial action by the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN) over a major labor dispute.
Industry Warning
Joy Ogaji, Chief Executive of the Association of Power Generating Companies (APGC), issued an alert on September 28. She said thermal plants had already been told to shut down, following directives from gas suppliers.
According to Ogaji, the Nigerian Gas Infrastructure Company has also instructed operators to comply. She warned this could push the national grid to the verge of collapse.
Union Strike Over Job Losses
PENGASSAN declared an indefinite strike after an emergency meeting on September 27. The union is protesting the dismissal of more than 800 workers at the Dangote Refinery, allegedly for union activity.
It has ordered members at oil and gas facilities to stop work, including gas supply to power plants, until the layoffs are reversed.
Power Supply Under Threat
Thermal plants provide over 70% of Nigeria’s electricity. Energy experts warn that hydroelectric dams alone cannot keep the national grid stable without gas supply. This could result in large-scale blackouts and power instability.
Broader Economic Impact
The strike could also disrupt crude oil production and fuel distribution, worsening Nigeria’s economic challenges. Union leaders claim the refinery has replaced dismissed workers with foreign staff, heightening tensions.
Call for Urgent Action
Ogaji urged the government, industry stakeholders, and union leaders to resolve the dispute quickly. With thermal plants on the brink of closure, the country’s energy security, businesses, and households are at serious risk.
Looking Ahead
If talks between PENGASSAN, the Dangote Group, and federal authorities fail, Nigeria could face a prolonged power crisis by the end of 2025.
