TCN Boosts Asaba Transmission Substation Transformer Capacity



TCN General Manager Public Affairs, Mrs Ndidi Mbah

The Transmission Company of Nigeria (TCN) has successfully completed the installation and commissioning of power transformer in its Asaba Transmission Substation, Delta State, on the 10th of January, 2020.

This is the first time TCN has installed and energized a 300MVA 330/132/33kV capacity power transformer in-house, even though its in-house engineers installed a greater number of the 68 power transformers added to the grid between February 2017 and December, 2019.

The new Asaba 300MVA 330/132/33kV capacity power transformer replaces a disused 150MVA 330/132/33kV Siemens brand transformer, commissioned by NIPP on the 15th of February, 2015. From 2015 to 3rd September, 2019, the 150MVA transformer tripped on two major faults, necessitating the invitation of experts on two occasions by Akay Nig. Ltd (NIPP Contractor) to effect repairs before restoration.

A statement by the TCN General Manager Public Affairs, Ndidi Mbah, explained that another 150MVA Siemens brand transformer was brought into the substation in 2016 and put on plinth, but was also discovered to be faulty.

The contractor then moved the transformer to GTI Workshop in Ikorodu, Lagos for repairs.
Before the newly energized 300MVA power transformer was installed,

TCN temporarily fed the Asaba Transmission Substation through the Onitsha-Asaba 330kV transmission lines connected to the Onitsha – GCM 132/33kV transmission line. This restricted maximum load transmission on Onitisha – Asaba transmission line.

With the commissioning of the new 300MVA power transformer however, TCN now has available 240MW bulk electricity available in Asaba TS, that would enable Benin Electricity Distribution Company (BEDC) distribute more stable and longer hours of electricity to its customers in Asaba Metropolis, Ogwashiukwu, Ibuzor, Agbor, and other towns in Delta North Senatorial Zone.

Meanwhile, TCN already has in place plans to utilize the extra plinth for an additional 150MVA power transformer in the substation as it plans to further expand the capacity of the substation in line with its Transmission Rehabilitation and Expansion Program (TREP).

She restated TCN resolve to continue to implement the incremental power policy of the Federal Government by consistently investing in capacity expansion initiatives, evidenced by several completed and ongoing projects in the transmission network nationwide.
