About Transmission Company of Nigeria (TCN)

In response to the increase in Nigeria’s demographic figures over the decades which is put at about 160 Million and the lack of commensurate increase in energy supply to meet the country’s growing economic and infrastructural development objective, the Federal Government of Nigeria realized that there was the need to break up defunct National Electric P

ower Authority (NEPA) into small, effective units, as adequate and efficient electric power is a major factor in modern industrial development. The unbundling of NEPA started when President Olusegun Obasanjo signed into law the Electric Power Sector Reform Act (EPSR Act) which led to the formation of the Power Holding Company of Nigeria (PHCN) with a transitory framework in March 2005. By this act, NEPA was unbundled into 18 companies: Six Generation Companies, One Transmission Company, and Eleven Distribution Companies. On its part, TCN was on July 1st, 2006 issued a Transmission License with the responsibilities of wheeling power at high Voltage, operate the National Grid and Market Operation Service
Coverage Area

TCN is spread across the country with 10 transmission regions in Lagos, Osogbo, Kaduna, Kano, Bauchi, Shiroro, Enugu, PortHarcourt, Benin, and Abuja; a National Control Center at Osogbo; 3 Supplementary National Control Centres at Shiroro, Benin, and Lagos, and 10 Regional Control Centers.

TCN, Police Arrest Suspect Over Vandalism of Six Towers Along Yola–Jalingo 330kV Transmission Line

The Transmission Company of Nigeria (TCN) wishes to inform the public that six of its transmission towers, T995, T998, T999, T1002, T1003, and T1004, along the Yola–Jalingo 330kV Transmission Line have been vandalized.

The incident was discovered during a routine line patrol by TCN Engineers on 29th July 2026, when it was observed that vandals had stripped critical bracing members from the affected towers, carting away an estimated 130 pieces of tower members. The act posed a severe structural threat to the towers.

Following the discovery, TCN, on 30th July 2026, conducted a joint raid with the Nigeria Police Force within the host community. During the exercise, the team engaged the village head and youth leadership, demanding their full cooperation in identifying and producing the perpetrators.

August 1st, 2026, the Police notified TCN that a principal suspect linked to the vandalism had been apprehended, and a that a portion of the stolen tower members had been recovered. TCN officials visited the site to verify the recovered materials and reiterated the call for the full prosecution of the suspect to ensure justice is served.

The Police have obtained solid leads from the suspect in custody and remain committed to tracking down the remaining members of the syndicate, investigations are ongoing.

We strongly condemn the continued vandalism of power transmission infrastructure as it undermines years of investment in the sector.

We appeal to host communities and the general public to remain vigilant and report any suspicious activity around transmission installations to security agencies or the nearest TCN office. Collective action is essential to protect national grid assets and ensure reliable power supply.

PRESS STATEMENT

The Nigerian "Stranded Power" Narrative, Reconsidered: What NERC's Own Q1 2026 Data Show

(All bracketed citations refer to the Nigerian Electricity Regulatory Commission's First Quarter 2026 Report ("the Report"), by section and printed page number, except where an external source is indicated. A full citation index follows the statement.)

The attention of the Transmission Company of Nigeria (TCN) has been drawn to a report published by THISDAY on 28 July 2026, titled "Gencos: Over 2,500MW Generated Power Wasted Due to Grid Unreliability," in which the Association of Power Generation Companies (APGC) is quoted as stating that "Nigeria's stranded power crisis is a transmission failure, not a generation failure," and that an installed capacity of "over 15,500MW" is being throttled by a grid that "can only wheel around 4,500MW."

TCN respects APGC's standing as a voice for Generation Companies (GenCos) and shares its concern for the millions of Nigerians without reliable power. However, the Commission's own First Quarter 2026 Report, published at the same time and covering the same period the THISDAY report describes, contains audited data for each plant that place the source of the "gap" referenced in the article at the power station fence, not the transmission gate.
