The Transmission Company of Nigeria (TCN) has successfully commissioned the turn-in-turn-out connections for the Ihovbor/Benin and Ihovbor/Ajaokuta 330kV transmission lines, strengthening electricity evacuation capacity and grid stability.

The development, confirmed in a statement by the General Manager, Public Affairs, Mrs. Ndidi Mbah, marks a significant milestone in Nigeria’s power infrastructure upgrade, according to The Business Bureau.

The commissioning was completed at 19:05 hours on Wednesday, April 23, 2026.

Improved Power Transmission Capacity

Mbah stated that the newly completed connections deliver the Ihovbor transmission corridor, enabling improved power evacuation from key generation sources.

“Presently, the Ihovbor/Benin Transmission Line is transmitting 200MW, while the Ihovbor/Ajaokuta line is transmitting 90MW,” she said.

The upgrade is expected to enhance electricity supply efficiency across the network while supporting growing energy demand.

Support for Power Generation Companies

The improved infrastructure provides additional evacuation capacity for major generation companies, including Niger Delta Power Holding Company (NDPHC) and Azura Power.

Industry analysts note that efficient evacuation remains a critical bottleneck in Nigeria’s electricity value chain, often limiting the full utilisation of available generation capacity.

Boost to Grid Stability and Reliability

According to TCN, the new transmission links will significantly improve grid stability and reliability, particularly in regions connected to the Ihovbor power plant.

The project forms part of broader efforts to modernise Nigeria’s transmission network and reduce system disruptions.

The Business Bureau analysis indicates that continued investments in transmission infrastructure are essential to unlocking Nigeria’s full power generation potential and improving electricity supply nationwide.
