The Transmission Company of Nigeria (TCN), on Tuesday, announced that the labour-related incident at the Afam IV Gas Power Station has disrupted electricity supply to parts of Port Harcourt and its environs in Rivers State.
TCN in a statement issued in Abuja, said the disruption began on Monday, September 28, 2026, after 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.
According to TCN, the action was linked to an ongoing labour dispute between the management of Afam IV Gas Power Station and NUEE.
The company said the development subsequently caused the 150MVA 330/132kV inter-bus transformer at Afam IV to trip, affecting bulk electricity transmission to parts of Port Harcourt and surrounding areas.
TCN said the affected transmission facilities included 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.
The company said it was engaging relevant stakeholders, including the Nigerian Independent System Operator (NISO), towards restoring the affected facilities.
“TCN is engaging relevant stakeholders, including the Nigerian Independent System Operator (NISO), to restore the affected facilities as soon as conditions allow safe restoration,” the statement said.
The company expressed regret over the inconvenience caused to electricity consumers in the affected areas, and assured that it would continue to provide updates as the situation develops.
