The Transmission Company of Nigeria (TCN) has rejected claims by the Abuja Electricity Distribution Company (AEDC) that a trip on 330kV transmission lines supplying Abuja from Shiroro Transmission Substation was responsible for the sharp reduction in power allocated to the distribution company.
AEDC had, in a notice to its customers dated August 26, 2026, attributed prevailing electricity supply constraints and a reduction in its allocation from about 641 megawatts (MW) to 314MW to the alleged tripping of transmission lines supplying the Abuja axis.
However, TCN, in a statement signed by its management on Wednesday, described the claim as “inaccurate and misleading,” insisting that the reduction in AEDC’s allocation was caused by low electricity generation on the national grid.
TCN stated that there had been no tripping of the 330kV transmission lines supplying Abuja from the Shiroro Transmission Substation.
“Contrary to the information contained in AEDC’s publication, all 330kV transmission lines within Abuja Region are currently in circuit, and no such tripping of the 330kV transmission lines supplying Abuja axis, as alleged by AEDC, has occurred,” the company said.
The transmission operator therefore maintained that the reduction in AEDC’s power allocation and the resulting load shedding across its feeders could not be blamed on any tripping of TCN’s 330kV transmission lines in the Abuja Region.
According to TCN, the development was instead linked to insufficient generation available on the national grid, which affected the amount of bulk electricity allocated to AEDC.
The Company called for accurate and clear communication of information concerning electricity supply challenges, stressing that misleading attribution could create confusion among electricity consumers.
TCN assured Nigerians of its continued commitment to transmitting available bulk electricity efficiently across the country while maintaining the stability, reliability and integrity of the national transmission grid.
Abuja Times reports that the clarification comes as residents and electricity consumers within the Abuja Electricity Distribution Company franchise area continue to experience supply constraints following the reported reduction in available power allocation.
