Labor Dispute Halts Power Supply in Port Harcourt Areas

Power supply disruptions have occurred in parts of Port Harcourt and surrounding areas following a labor-related incident at the Afam IV Power Station. The Transmission Company of Nigeria (TCN) reported that the disruptions began on September 28, 2026, when members of the National Union of Electricity Employees (NUEE), Rivers State Chapter, opened the Afam–Alaoji 330kV Transmission Line 2 at the Alaoji 330kV Transmission Substation.
This action was linked to an ongoing labor dispute between NUEE and the management of Afam IV Gas Power Station. As a result, the 150MVA 330/132kV inter-bus transformer at Afam IV tripped, impacting bulk electricity transmission to Port Harcourt and nearby areas.
Affected facilities include the Port Harcourt Town 132kV Transmission Substation, Elelenwo 132kV Transmission Substation, and the 60MVA 132/33kV transformer at the Port Harcourt Mains 132kV Transmission Substation. TCN is engaging stakeholders, including the Nigerian Independent System Operator (NISO), to restore services as soon as conditions permit.
