Power transmission in Nigeria’s South-South has received a major lift, with the Transmission Company of Nigeria (TCN) installing 635MVA of new transformer capacity at key substations in its Port Harcourt Region, while work continues on further projects to make the grid more reliable.
The General Manager of the Port Harcourt Region, Engr. Nasiru Bello, announced this in an exclusive interview with TCN Transmission News.
He outlined the region’s infrastructure progress, capacity upgrades and ongoing projects designed to ease transmission constraints.
Engr. Bello said the added capacity allows the network to carry more power and deliver bulk electricity more effectively to distribution load centres, which then supply consumers.
The 635MVA is made up of one 125MVA power transformer at Port Harcourt Town Transmission Substation, two 125MVA transformers at Port Harcourt Main Transmission Substation, one 125MVA transformer at Alaoji Transmission Substation, one 75MVA transformer at Aba Transmission Substation and one 60MVA transformer at Itu Transmission Substation.
Other projects are also under way. In the Calabar Sub-Region, construction is continuing on the 2x160MVA Ekori and 2x160MVA Obudu Transmission Substations, and the Ogoja Transmission Substation is about 90 percent complete.
Engr. Bello added that plans for a new transmission substation in Oron, Akwa Ibom State, have been finalised, with site mobilisation and project execution due to start soon.
He noted that these expansion works are backed by routine maintenance and rehabilitation of assets across the region.
According to him, such efforts improve equipment reliability, reduce avoidable downtime and cut technical losses on the network.
They also support TCN’s wider mandate to expand and modernise the national transmission system so that bulk power reaches distribution load centres across the South-South and the country as a whole.
