The Transmission Company of Nigeria (TCN) says that recorded 131 cases of infrastructure vandalism across its network in 2025, despite achieving a historic milestone in electricity transmission.
The Managing Director and Chief Executive Officer of TCN, Sule Abdulaziz, said in his end-of-year message to staff, partners, and stakeholders, that 2025 was a “remarkable and historic year” for the company and Nigeria’s electricity industry.
He noted that despite the challenges posed by vandalism and other operational constraints, the company recorded an all-time peak electricity transmission of 5,801.84 megawatts on March 4, 2025.
According to him, the achievement was accompanied by a maximum daily energy delivery of 128,370.75 megawatt-hours nationwide, the highest ever recorded on Nigeria’s national grid.
He explained that the milestone was driven by deliberate investments in infrastructure rehabilitation, expansion of transformer capacity, and sustained maintenance of transmission assets.
“Dear colleagues, valued partners, and stakeholders, as we come to the end of another challenging and remarkable year at TCN, I want to take a moment to express my heartfelt gratitude and appreciation for the incredible dedication and resilience you have all shown,” Abdulaziz said.
“No doubt, this year has presented its unique set of challenges, from evolving regulatory landscapes to the persistent issues of infrastructure vandalisation and liquidity constraints that affect our operations. Yet, it is in overcoming these obstacles that the true strength of our team shines through.
“This year, we made deliberate strides to strengthen our infrastructure, rehabilitate ageing assets, and expand transformer capacity across the country. With these efforts, TCN’s wheeling capability has grown to 8,700MW, ensuring that we are better prepared to support the nation’s increasing demand for electricity.
“A highlight of our progress came on March 4, 2025, when TCN transmitted an all-time peak generation of 5,801.84MW with a maximum daily energy of 128,370.75MWh delivered nationwide; the highest ever recorded in the country’s history,” he added.
Between January 2024 and November 2025, Abdulaziz said 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.
He, however, 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.
