NOTICE OF ONGOING MAINTENANCE AT 132/33kV DELTA TRANSMISSION SUBSTATION The Transmission Company of Nigeria, TCN, Delta Sub-Region, wishes to inform the public that the ongoing preventive maintenance at its Delta 132/33kV Transmission Substation, which commenced yesterday, 4 June 2026, is progressing as scheduled. The work will continue daily from 10:00 a.m. to 5:00 p.m. until 16 June 2026. The maintenance is to facilitate the connection of a bus coupler circuit breaker and the rehabilitation of five isolators on the main busbar. Consequently, 33kV feeders emanating from transformers at Effurun and Delta 132/33kV Transmission Substations, including Effurun, Warri, Sapele, Osubi, PTI, PMSL, Refinery I, Refinery II, and Enerhen feeders, as well as Isoko/Kwale, Otovwodo/Patani, Ughelli/Shell, Agbarho/Eku, Aladja, Imoniyame, and Beta Glass feeders, will be out of service during the maintenance period. However, power supply will be restored daily at 5:00 p.m., enabling Benin DisCo to offtake electricity for its customers, following the completion of each day’s maintenance activities. TCN apologizes for every inconvenience caused by the ongoing maintenance exercise. Ndidi Mbah GM, Public Affairs 5/6/26

SIX TCN TOWERS VANDALIZED ALONG APIR–LAFIA 330KV TRANSMISSION LINES The Transmission Company of Nigeria, TCN, wishes to inform the public that six transmission towers, from T125 to T130, on Apir–Lafia 330kV Transmission Lines I and II have been vandalized. The collapse occurred at about 1:15 a.m. on 30th May 2026, during a heavy downpour. Trial reclosure of these line II was made at 2:08 am following the initial tripping and failed. The tripping of lines prompted a physical line trace to determine the fault which revealed damage to critical components of towers T125 to T130, confirming acts of vandalism on the affected sections of the transmission corridor. As a result, both Apir–Lafia 330kV Transmission Lines I and II remain out of service pending reconstruction of the affected towers. TCN engineers have been mobilized to site to assess the extent of damage and ascertain materials required to commence to restore normal transmission along the corridor. Meanwhile, the Lafia 330kV Transmission Station is being supplied through the Lafia–Jos transmission line as a temporary measure to minimise the impact of the outage on affected electricity customers within the franchise areas of Abuja Electricity Distribution Company (AEDC) and Jos Electricity Distribution Company (JEDC). TCN strongly condemns the continued vandalism of power transmission infrastructure as it undermines years of investment in the sector. We appeal to host communities and the general public to remain vigilant and report any suspicious activities around transmission installations to security agencies or the nearest TCN office. Collective action is essential to protect national grid assets and ensure reliable power supply. Ndidi Mbah GM, Public Affairs 3/6/26 #tcnnigeria #electricity #vandalism
