Three transmission towers collapsed
According to TCN, investigations conducted after the line tripped showed that Towers T78, T79 and T80 had collapsed.
The company said it immediately isolated the affected transmission line to ensure the safety of its personnel and the public.
TCN said the development has affected electricity supply through the Keffi and Akwanga Transmission Substations.
The company said in a statement issued on Thursday:
“Consequently, all 33kV outgoing feeders at the Keffi and Akwanga Transmission Substations are presently unavailable."
The transmission company added that no load could be nominated on the affected feeders until further notice.
The outage is expected to affect electricity customers supplied through the affected substations in Keffi, Akwanga and surrounding areas.
TCN begins restoration assessment
TCN said its engineers were already at the site to assess the extent of the damage caused by the collapsed towers.
The assessment will help the company determine the materials and other requirements needed to commence restoration work on the affected transmission line.

TCN gives reason as power blackout hits 2 Nigerian states
Earlier, Legit.ng reported that parts of Rivers and Abia states lost electricity on Monday, September 28, 2026, after members of the National Union of Electricity Employees (NUEE), Rivers State Chapter, triggered a disruption at a critical transmission point during an ongoing labour dispute.
TCN confirmed the incident in a statement, saying NUEE members opened the Afam–Alaoji 330kV Transmission Line 2 at the Alaoji 330kV Transmission Substation.
The development followed a disagreement between the union and the management of the Afam IV Gas Power Station.
According to TCN, the line was opened during the incident, triggering the 150MVA 330/132kV inter-bus transformer at Afam IV and disrupting bulk power transmission to Port Harcourt and nearby areas.
