The Transmission Company of Nigeria (TCN) recorded a historic milestone in electricity transmission, reaching an all‑time peak of 5,801.84 MW on 4 March 2025. Despite challenges such as infrastructure vandalism, the company has made notable progress in expanding capacity and improving grid stability.
In his end‑of‑year message, Managing Director and Chief Executive Officer Sule Abdulaziz highlighted several achievements. Between January 2024 and November 2025, TCN commissioned 82 new power transformers, adding more than 8,500 MVA to the national grid and enhancing reliability and efficiency. However, vandalism remains a major concern, with 131 incidents reported across the network during the same period. To combat this, TCN is collaborating closely with security agencies and community groups to protect critical infrastructure.
The company has also advanced donor‑funded projects worth over $1.16 billion, including the Abuja Feeding Scheme, which involves constructing five new substations and a 330 kV transmission line. These initiatives aim to modernize the grid, expand capacity, and prepare TCN to meet the energy needs of a growing economy.
Abdulaziz commended TCN staff for their dedication and expressed gratitude to stakeholders, including President Bola Ahmed Tinubu and the Minister of Power, for their support. Looking ahead to 2026, TCN plans to intensify efforts to increase grid capacity, stability, and efficiency, while deepening collaboration with stakeholders to strengthen Nigeria’s electricity supply industry.
The record peak achieved in 2025 reflects growing stability and expanded capacity in Nigeria’s power sector, despite persistent challenges. As the backbone of the nation’s electricity transmission, TCN’s progress is crucial for economic growth and development. With continued investment in infrastructure and stakeholder collaboration, TCN is poised to play a vital role in Nigeria’s energy future.
