“Between July 1 and Aug. 11, TCN installations have experienced numerous vandalism attacks. These incidents are widespread, affecting every transmission region.
“On Aug. 11, vandals attacked towers T377, T378, and T379 along the Gombe-Damaturu 330kV transmission line, which is undergoing rapid and urgent repair,” she said.
She said that the repair followed a previous vandalism incident involving IEDs on towers T193 and T194, adding that two of the vandals were killed by hunters at the Damaturu end of the line.
”On Aug. 3 and Aug. 5, vandals attacked towers along two transmission line routes under Enugu Region of TCN.
“The first attack targeted tower T9 on the Apir-Aliede 330kV transmission line, and the second one targeted tower T12 on the Apir-Otukpo-Yandev 123kV transmission line, both passing through Ikpayango Village.
”In response to the first incident, the local vigilante group acted promptly, preventing the vandals from stealing the skywire after it had been brought down.
”Also on August 5, vandals managed to cut off and stole the yellow phase conductor from towers T11 to T12 along the Apir-Otukpo-Yandev line.
“This caused a tripping of the 150 Mega Volt Ampere (MVA) power transformer at the Apir transmission substation,” Mbah said.
She said that TCN engineers responded swiftly by removing the remaining conductors on tower T11, allowing the continued supply of bulk electricity to Yandev, Otukpo, and Takum through the 132kV New Haven-Otukpo transmission line.
She said that TCN team had successfully sectionalised the affected towers to facilitate repairs.
Accordimg to her, they have also stabilised both ends of the sectionalised network that supply power to Otukpo, Yandev, and Takum from the New Haven Substation, while the 150MVA transformer has been tested and restored.
“On July 24, in Osogbo Region, Tower T328 along the 330kV Osogbo-Ganmo line in the Oba-Oke area of Osogbo, Osun State, was also vandalised.
“The incident caused severe structural damage to the tower, leaving it twisted and bent, with insulators at a dangerous angle of 65° to 70°.
“The damaged and bent tower T328 also affected towers T327 and T329 on either side.
“Despite the precarious condition of T328, the cables remained supported by the bent towers, preventing power outage.
“The Osogbo Region of TCN has since carried out emergency repair work on the affected towers to prevent their collapse, while awaiting permanent reconstruction of Tower T328,” she said.
The TCN spokesperson said that the incidents in Osogbo have all been reported to security operatives, including the Military, Police, DSS, and Civil Defence.
”Additionally, more local vigilantes have been employed to monitor the facilities,” she said.
Mbah also disclosed that on July 19, in the Benin Region of TCN, tower T449 at Oluku Community along the Ihovbor/Benin 330kV transmission line was vandalised.
She said that the three legs and supporting members were cut off, adding that TCN engineers swiftly carried out temporary repairs to prevent collapse.
“Also, on July 25, tower T72 along the Benin/Egbin 330kV transmission line, also in Oluku Community, was vandalised.
“The four legs of the tower (B6N) were cut off. TCN’s engineers again reinforced the tower legs to prevent collapse.
”In the Port Harcourt Region, vandals attacked Towers T98 and T99 along the Ahoada-Yenagoa 132kV line on July 29, causing them to collapse.
“These towers were located in the Igbogene Community of Bayelsa State.
”On August 3, Tower T97 along the same line also collapsed due to instability from the adjacent collapsed towers, compounded by storm and wind effects.
”Repair work has commenced, including cracking and clearing the affected tower bases to facilitate the complete reconstruction of the towers,”she said.
According to her, transmission lines in the North East, under the Bauchi Region of TCN have suffered multiple vandalism attacks at various points.
