The Transmission Company of Nigeria (TCN) has increased its electricity wheeling capacity to 8,700 megawatts (MW) in 2025 following sustained efforts to strengthen infrastructure, rehabilitate aging assets, and expand transformer capacity nationwide.
The Managing Director and Chief Executive Officer of TCN, Sule Abdulaziz, disclosed this in his 2025 End-of-Year Goodwill Message titled “Reflecting on a Year of Progress and Powering Our Future Together.”
According to him, the achievements position the company to better support Nigeria’s growing electricity demand.
Abdulaziz highlighted that a major milestone was recorded on March 4, 2025, when TCN transmitted an all-time peak generation of over 5,800MW, alongside a record maximum daily energy delivery of 128,370.75MWh, the highest in the nation’s history within the period under review.
He also noted that the commissioning of 82 new power transformers and adding more than 8,500MVA to the national grid, significantly improved reliability and capacity.
The TCN boss further stated that the company advanced several critical transmission projects valued at over $1.16 billion, funded by development partners.
Key among them is the Abuja Feeding Scheme, which includes the construction of five new substations and a 330kV transmission line aimed at modernising the grid and expanding capacity.
Challenges
Despite the progress, Abdulaziz acknowledged challenges such as vandalism, with 131 incidents recorded between January and November 2025.
He said TCN is collaborating with security agencies, the Office of the National Security Adviser, and host communities to curb the menace and safeguard critical infrastructure.
He also noted that the successful unbundling of TCN and the take-off of the Nigerian Independent System Operator (NISO) marked a turning point for the sector, allowing TCN to focus on transmission infrastructure development while NISO handles system and market operations.
Looking ahead to 2026, Abdulaziz said TCN would intensify efforts to modernise infrastructure, accelerate project implementation, and deepen stakeholder engagement to further strengthen grid stability and efficiency.
