The Transmission Company of Nigeria (TCN) has dismissed claims that the reduction in electricity allocation to the Abuja Electricity Distribution Company (AEDC) was caused by the tripping of 330kV transmission lines supplying the Federal Capital Territory from the Shiroro Transmission Substation.
TCN, in a statement signed by its Management on Wednesday, said the reduction in AEDC’s allocation was instead caused by low power generation on the national grid.
The clarification followed a publication by AEDC dated August 26, 2026, in which the electricity distribution company informed its customers of prevailing supply constraints and attributed the reduction in its allocation from approximately 641 megawatts (MW) to 314MW to the alleged tripping of transmission lines supplying Abuja from Shiroro.
TCN described the claim as “inaccurate and misleading,” stressing that no 330kV transmission line supplying the Abuja axis had tripped.
“Contrary to the information contained in AEDC’s publication, all 330kV transmission lines within Abuja Region are currently in circuit,” TCN stated.
The transmission company maintained that the reduction in AEDC’s allocation, and the resulting load shedding across its feeders, could therefore not be attributed to any tripping of TCN’s 330kV transmission lines within the Abuja Region.
TCN urged stakeholders to ensure accurate and clear dissemination of information, particularly on issues affecting electricity supply and the stability of the national grid.
The company reaffirmed its commitment to efficiently transmitting available bulk electricity across the country while maintaining the stability, reliability and integrity of Nigeria’s transmission network.
