The Transmission Company of Nigeria (TCN) has rejected claims that a tripped transmission line caused the recent drop in electricity supply to Abuja, insisting that all 330kV lines feeding the region remain fully intact and operational.
TCN was responding to an August 26, 2026 notice from the Abuja Electricity Distribution Company (AEDC), which informed customers of ongoing supply constraints and attributed a drop in its power allocation, from about 641MW to 314MW, to an alleged tripping of transmission lines from the Shiroro Transmission Substation.
Describing this claim as inaccurate and misleading, in a statement on Wednesday, TCN said the real cause was low power generation on the national grid, not any fault on its transmission network. The company stressed that no 330kV line supplying the Abuja axis has tripped, and that all lines in the Abuja Region are currently in circuit.
TCN said the reduced allocation to AEDC, and the load shedding that followed on its feeders, should not be linked to any failure on TCN’s part, and called for greater accuracy in public communications about the state of the grid.
The company reaffirmed its commitment to transmitting available electricity efficiently across the country and to maintaining the stability, reliability, and integrity of Nigeria’s transmission network.
