Total electricity blackout affects Rivers and two other Nigerian states.

Rivers, Bayelsa and Imo states are experiencing a complete blackout after the Transmission Company of Nigeria (TCN) reported a forced outage on its Alaoji 132‑kilovolt transmission line.

TCN spokesperson Ndidi Mbah stated that the outage began at approximately 3:39 am on Tuesday.

TCN cited an earth fault and a failure of distance protection on the Alaoji line as the cause.

Consequently, the Port Harcourt Electricity Distribution Company (PHEDC) cannot off‑take power for its customers in Owerri (Imo), Yenagoa (Bayelsa) and Ahoada (Rivers).

“The Transmission Company of Nigeria (TCN) informs the public that a forced outage occurred on the Alaoji 132 kV Transmission Line at about 3:59 am today, Tuesday, June 23, 2026, due to an earth fault and distance protection failure. TCN’s maintenance crew has already begun work on the line to restore normal bulk power supply as quickly as possible. As a result, the Port Harcourt Electricity Distribution Company (PHEDC) has been unable to off‑take electricity for distribution to its customers in Owerri, Yenagoa, and Ahoada. TCN apologizes for any inconvenience caused to affected customers.”
