TCN Boosts Capacity of Port Harcourt Main Substation with 100MVA Transformer, Expands Capacity Across the Region
The Transmission Company of Nigeria (TCN) has commissioned a 100MVA 132/33kV power transformer at its Port Harcourt Main Substation, enhancing the bulk transmission capability of the substation by 80MW.
In a statement signed by the spokesperson of the transmission company, Ndidi Mbah, noted that the initiative, which is a TCN-World Bank project, also includes the complete rehabilitation and expansion of the 132/33kV transmission substation and the addition of three feeders and associated accessories.
“With the installation of the 100MVA power transformer, the substation’s installed capacity increased from 180MVA to 280MVA. Notably, industries in the Trans Amadi industrial environment and communities beyond Port Harcourt city will benefit significantly from this capacity expansion.
“Within the first quarter of this year, TCN has executed a number of projects in its Port-Harcourt Region, and currently has several ongoing projects which are at various completion stages, including a 100MVA transformer installation in Port Harcourt Town which will soon be completed and commissioned. Transformer projects are equally ongoing in Port -Harcourt Town, Itu, Umuahia, Aba, and Alaoji, aimed at bolstering bulk power transmission within the region.
“In its Port Harcourt Sub-region, TCN recently received four power transformers including two units of 100MVA capacity transformers, one each at Port Harcourt Main and Port Harcourt Town transmission substations, two units of 60MVA power transformers, one each were also sent to Rumuosi and Port Harcourt Main transmission substations. Collectively, these will increase available capacity within TCN’s Port Harcourt region for Port Harcourt Distribution company to offtake for its customers. 
“At the Uyo Work Centre, TCN is also currently upgrading the Itu Substation with a 60MVA 132kV transformer and associated switch gears. Upon completion, the station’s capacity will increase by 48MW.
“Ongoing new substation projects within the region include the construction of a 2x60MVA 132/33kV transmission substation at Oron and a 2×30/40MVA 132/33kV Substation at Ididep both in Calabar”, TCN stated.
According to the transmission company, “To increase maintenance efficiency and invariably reduce downtime, the Regional Store received bulk consignment of spare parts, including circuit breakers, 33kV lighting arresters, battery chargers, battery banks, toolboxes, and safety kits.
“TCN remains steadfast in its effort to put in place a robust and more efficient transmission grid through strategic initiatives and project implementation across regions. It is also committed to swift maintenance and fault response by ensuring it has available, necessary spare parts in its stores nationwide”, the company said.
