TCN Begins Delta Substation Maintenance, Announces Daily Power Outages

The Transmission Company of Nigeria (TCN), Delta Sub-Region, has announced ongoing preventive maintenance at its Delta 132/33kV Transmission Substation, which began on June 4, 2026, and is expected to continue until June 16, 2026.

According to TCN, the maintenance exercise is being carried out daily between 10:00 a.m. and 5:00 p.m. as part of efforts to improve the efficiency and reliability of the transmission network.

The company explained that the work involves the installation of a bus coupler circuit breaker and the rehabilitation of five isolators on the main busbar.

As a result, several 33kV feeders from the Effurun and Delta 132/33kV transmission substations will be affected during the maintenance period.

The affected feeders include Effurun, Warri, Sapele, Osubi, PTI, PMSL, Refinery I, Refinery II, Enerhen, as well as Isoko/Kwale, Otovwodo/Patani, Ughelli/Shell, Agbarho/Eku, Aladja, Moneyman, and Beta Glass feeders.

However, TCN stated that power supply will be restored daily by 5:00 p.m., allowing the Benin Electricity Distribution Company (DisCo) to resume electricity supply to customers after each maintenance window.

The agency appealed for public understanding, noting that the exercise is necessary to strengthen the transmission infrastructure and improve long-term power stability in the region.

TCN also apologized for the inconvenience caused during the maintenance period.

“TCN apologizes for every inconvenience caused by the ongoing maintenance exercise,” the statement read.
