TCN Explains Port Harcourt Power Disruption, Blames Labour Dispute
Electricity supply has been disrupted in parts of Port Harcourt and its environs following a labour-related incident at the Afam IV Power Station in Rivers State.
The Transmission Company of Nigeria (TCN), in a statement, 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 explained that the development caused the 150MVA 330/132kV inter-bus transformer at Afam IV to trip, thereby affecting bulk electricity transmission to parts of Port Harcourt and surrounding areas.
TCN said the affected transmission 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.
The transmission company said it is engaging relevant stakeholders, including the Nigerian Independent System Operator (NISO), to facilitate the restoration of the affected facilities as soon as conditions permit safe restoration.
TCN expressed regret over the inconvenience caused to electricity consumers in the affected areas and assured the public that updates would be provided as the situation develops.
