Transmission Company of Nigeria reports power disruptions in Port Harcourt

Parts of Port Harcourt and surrounding areas in Rivers State have experienced electricity supply disruptions following a labour dispute. The Transmission Company of Nigeria (TCN) reported that the outage began on Monday, September 28, 2026.

The disruption was caused by members of the National Union of Electricity Employees (NUEE), Rivers State Chapter, who opened the Afam–Alaoji 330kV Transmission Line 2 at the Alaoji 330kV Transmission Substation. This action was linked to an ongoing dispute between the union and the management of the Afam IV Gas Power Station.

The incident caused the 150MVA 330/132kV inter-bus transformer at Afam IV to trip, affecting bulk electricity transmission. Impacted facilities include the Port Harcourt Town 132kV Transmission Substation, the Elelenwo 132kV Transmission Substation, and the 60MVA 132/33kV transformer at the Port Harcourt Mains 132kV Transmission Substation. TCN is working with the Nigerian Independent System Operator (NISO) to restore services as soon as it is safe to reconnect.
