TCN Strengthens National Grid With New Transmission Lines

The Transmission Company of Nigeria has strengthened the national grid with the commissioning of new transmission line connections at the Ihovbor corridor, aimed at improving power evacuation and enhancing grid stability.

The project involves the turn-in-turn-out connections for the Ihovbor/Benin and Ihovbor/Ajaokuta 330kV transmission lines, which were successfully commissioned at 19:05 on Wednesday, April 23, 2026.

According to a statement by the General Manager, Public Affairs at TCN, Ndidi Mbah, on X on Friday, the development provides additional evacuation capacity for the Niger Delta Power Holding Company (NDPHC) and Azura Power plants, improving the ability to transmit generated electricity to the national grid.

The company confirmed that the Ihovbor/Benin transmission line is currently carrying about 200 megawatts, while the Ihovbor/Ajaokuta line is transmitting around 90 megawatts.TCN said the new infrastructure is expected to enhance the reliability of electricity supply by reducing transmission constraints in the corridor and strengthening overall grid performanceSpeaking on the development, TCN described the project as a key step in improving power evacuation capacity and supporting more efficient distribution of generated electricity across the network.

“The commissioning delivers the Ihovbor corridor and provides additional evacuation capacity for NDPHC and Azura Power.’’It added that the new lines will “strengthen power evacuation from the Ihovbor generating plant and improve grid stability and reliability in the affected regions.”

The company noted that the intervention aligns with ongoing efforts to expand and modernise Nigeria’s transmission infrastructure to support growing electricity demand.
