Parts of Port Harcourt and its environs are experiencing electricity supply disruption following a labour related incident at the Afam IV Power Station, the Transmission Company of Nigeria (TCN) has 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.
TCN said the action was linked to an ongoing labour dispute between the management of Afam IV Gas Power Station and NUEE.
According to the transmission company, the incident caused the 150MVA 330/132kV inter bus transformer at Afam IV to trip, disrupting bulk electricity transmission to parts of Port Harcourt and surrounding areas.
The 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 said it is engaging relevant stakeholders, including the Nigerian Independent System Operator (NISO), to restore the affected facilities as soon as conditions permit safe restoration.
The company expressed regret over the inconvenience caused to electricity consumers in the affected areas and said it would continue to provide updates as the situation develops.
