The Transmission Company of Nigeria (TCN) has disclosed that it recorded 131 cases of infrastructure vandalism across its network in 2025.
Managing Director and Chief Executive Officer of TCN, Sule Abdulaziz, disclosed this in his end-of-year message to staff, partners, and stakeholders.
He described 2025 as a “remarkable and historic year” for the company and Nigeria’s electricity industry as it achieved a historic milestone in electricity transmission.
Despite the challenges posed by vandalism and other operational constraints, Abdulaziz said the TCN recorded an all-time peak electricity transmission of 5,801.84 megawatts on March 4, 2025 and a maximum daily energy delivery of 128,370.75 megawatt-hours nationwide, the highest ever recorded on Nigeria’s national grid.
He stated that the milestone was driven by deliberate investments in infrastructure rehabilitation, expansion of transformer capacity, and sustained maintenance of transmission assets.
Abdulaziz said between January 2024 and November 2025, TCN commissioned 82 new power transformers, adding more than 8,500 megavolt-amperes to the national grid in a bid to boost reliability and capacity.
However, he lamented that vandalism remains a major threat to grid stability, noting that the company recorded 131 vandalism incidents across its network between January and November 2025.
“From January to November 2025 alone, the company recorded 131 vandalism incidents across its network. Management is working closely with the Office of the National Security Adviser, security agencies, and community vigilante groups to curb this menace,” he said, adding that TCN would continue sensitisation campaigns and community engagement to safeguard critical infrastructure.
Abdulaziz also highlighted key sector reforms recorded in 2025, including the unbundling of TCN and the successful launch of the Nigerian Independent System Operator.
He further disclosed that donor-funded projects valued at over $1.16bn were advanced during the year, including the Abuja Feeding Scheme, which involves the construction of five new substations and a new 330kV transmission line.
“TCN also advanced several critical projects funded by our development partners valued at over $1.16bn. This partnership has resulted in projects such as the Abuja Feeding Scheme, which includes the construction of five new substations and a new 330kV transmission line. Some of these projects are already completed, while others are ongoing, aimed at modernising the grid, expanding capacity, and preparing TCN to meet the energy needs of a growing economy,” he said.
The managing director commended staff for their dedication, describing them as the company’s “greatest asset,” and expressed gratitude to President Bola Ahmed Tinubu, the Minister of Power, Chief Adebayo Adelabu, security agencies, development partners and other sector stakeholders for their support. He also expressed condolences to the families of staff who lost their lives in 2025.
Looking ahead to 2026, Abdulaziz said TCN would intensify efforts to increase grid capacity, stability, and efficiency, while deepening collaboration with NISO and other stakeholders to strengthen Nigeria’s electricity supply industry.
