The Transmission Company of Nigeria (TCN) achieved a historic milestone in March 2025, generating an all-time peak of 5,801.84 megawatts (MW) of electricity, marking the highest ever recorded in the country’s history. This achievement reflects significant improvements in Nigeria’s power sector, driven by deliberate investments in infrastructure rehabilitation, expansion of transformer capacity, and sustained maintenance of transmission assets.
The TCN’s Managing Director, Sule Abdulaziz, attributed this success to the dedication of engineers across the power sector, including generation, transmission, and distribution companies. The achievement was accompanied by a maximum daily energy delivery of 128,370.75 megawatt-hours (MWh) nationwide, showcasing the country’s growing energy demands.
Between January 2024 and November 2025, TCN commissioned 82 new power transformers, adding over 8,500 megavolt-amperes to the national grid, boosting reliability and capacity. The company has also advanced several donor-funded projects valued at over $1.16 billion, including the Abuja Feeding Scheme, which involves constructing five new substations and a 330kV transmission line.
Despite these achievements, TCN faces challenges, including 131 vandalism incidents across its network between January and November 2025, threatening grid stability. The company is working with security agencies and community vigilante groups to curb this menace and has intensified sensitization campaigns and community engagement to safeguard critical infrastructure.
TCN’s wheeling capacity has grown to 8,700MW, positioning the company to support Nigeria’s increasing electricity demand. The Federal Government aims to increase this capacity to 10,000MW within two years, driven by ongoing investments in grid infrastructure and upgrades.
The achievement marks a significant step forward for Nigeria’s power sector, but experts note that the country still requires at least 30,000MW to meet its energy needs. Would you like to know more about Nigeria’s power sector reforms or TCN’s plans to address energy challenges?
