The Transmission Company of Nigeria (TCN) has restored the Alaoji–Owerri 132kV Transmission Lines 1 and 2, bringing the transmission corridor back to full operation and enabling electricity distribution companies to resume full load supply to customers.
In a statement issued on Thursday by the General Manager Public Affairs Ndidi Mbah, TCN disclosed that Line 1 was energized at 7:05 p.m., while Line 2 was restored at 7:06 p.m. following the successful completion of repair works on both lines.
The company explained that the transmission lines had tripped on Tuesday, June 23, 2026, prompting its maintenance crew to immediately mobilize to the fault location for repairs.
According to TCN, after repairs were completed on Line 1, the line was restored at about 7:25 p.m. on Tuesday, allowing partial restoration of bulk electricity transmission to Imo State, Yenagoa in Bayelsa State, and parts of Rivers State, including Ahoada.
The company noted that Line 1 was later temporarily de-energized to ensure the safe repair of Line 2.
The statement explained that the close proximity of the two high-voltage lines could have resulted in electromagnetic induction on the faulty line if the adjacent line remained energized, thereby posing a safety risk to maintenance personnel.
TCN said the temporary outage of Line 1 was approved by the Nigerian Independent System Operator (NISO) and carried out with the concurrence of the Enugu Electricity Distribution Company (EEDC) and the Port Harcourt Electricity Distribution Company (PHEDC).
The measure, it added, provided the safe working environment required for engineers to complete repairs and restore Line 2 to service.
With both transmission lines now fully operational, TCN said EEDC and PHEDC can resume full load offtake for distribution to consumers within their franchise areas.
The company expressed appreciation to electricity consumers affected by the outage for their patience and understanding, while apologizing for the inconvenience caused.
TCN reaffirmed its commitment to maintaining a reliable and efficient transmission network for the evacuation and delivery of bulk electricity across Nigeria.
