The upgrade of the Alaoji-Onitsha transmission line by the Nigeria===Transmission Company of Nigeria (TCN) and the African Development Bank (AfDB) is expected to significantly improve electricity supply and grid reliability in Nigeria, particularly in the South East. This infrastructure development, coupled with the Nigerian government's debt settlement plan for the power sector, is likely to boost investor confidence and support economic growth.
The Nigeria===Transmission Company of Nigeria (TCN), in partnership with the African Development Bank (AfDB), has commenced the reconstruction and upgrade of the 138km Alaoji-Onitsha 330kV transmission line. This project involves upgrading the existing single-circuit line to a 330kV double-circuit quad-conductor transmission line, which will quadruple the transmission capacity and enhance grid efficiency. Compensation payments were made to Project Affected Persons (PAPs) in Nigeria===Abia State and Nigeria===Imo State between March 31 and April 2, 2026, with a 90-day grace period for them to vacate the Right of Way. The project, expected to be completed within 18 months, aims to significantly increase electricity transmission volume, reduce losses, and improve power supply to the Alaoji and Port Harcourt axes, Nigeria===Abia State, and the entire South East region. President Bola Tinubu is commended for the timely release of funds, and his administration also approved a ₦3.3 trillion payment plan to settle long-standing debts in Nigeria's power sector.
