TCN Boosts National Grid with Commissioning of Ihovbor 330kV Transmission Lines in Edo

The Transmission Company of Nigeria (Transmission Company of Nigeria) has commissioned the Ihovbor/Benin and Ihovbor/Ajaokuta 330kV Turn-In Turn-Out transmission lines at its Ihovbor Substation in Edo State, in a move aimed at strengthening power evacuation across the national grid.

The project, commissioned on May 14, 2026, was described as a key infrastructure upgrade that will improve grid stability and enhance electricity supply to distribution companies nationwide.

Strengthening Transmission Capacity

Managing Director/CEO of TCN, Sule Ahmed Abdulaziz, said the 14km double-circuit transmission line links the existing Benin/Ajaokuta 330kV corridor to the Ihovbor substation, creating additional routes for power flow and improving system flexibility.

He explained that the development enhances TCN’s capacity to evacuate electricity from major generation plants, including Azura and Niger Delta Power Holding Company assets, while easing transmission constraints within the Benin corridor.

According to him, the project adds about 600MW of wheeling capacity, enabling distribution companies to access more bulk power for both residential and industrial consumers.

Technical Scope and Execution

The project was executed by Energo Nigeria and includes 30 transmission towers fitted with twin Bison conductors capable of handling up to 1.5GW of electricity load.

The contractor noted that the successful completion was achieved through close coordination with TCN and relevant stakeholders.

Overcoming Longstanding Delays

TCN’s General Manager (Engineering), Engr. Mojid Akintola, disclosed that the project was awarded in 2017 but was delayed due to right-of-way disputes and funding constraints, which have now been resolved.

He commended the collaboration between engineers, contractors, and host communities that made the commissioning possible.

Clarifying Roles in the Power Sector
The General Manager of the Benin Region, Engr. Charles Iwuamadi, reiterated that TCN operates strictly as a bulk electricity transmitter, while distribution companies handle delivery to end-users.

He stressed that the new infrastructure will increase available bulk power for distribution companies to serve customers more effectively.

Community Appeal

Representing the Ihovbor/Evbueka community, Mr. Elliot Imafido welcomed the project but appealed for improved electricity supply to the host community and greater inclusion of indigenes in employment opportunities.

The commissioning marks another step in ongoing efforts to expand Nigeria’s transmission network and improve overall power sector reliability.
