The Transmission Company of Nigeria (TCN) says it has boosted power supply to Asaba, the Delta State capital, with a new 300MVA transformer located at the Asaba Transmission Substation.
TCN said the new transformer doubles the one that had existed at the facility.
A statement by the transmission company’s General Manager, Public Affairs, Ndidi Mbah in Abuja said the transformer was energized on Jan. 10.
Mrs. Mbah explained that “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”.
She said the new 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. 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”.
The company noted that 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”, she added.
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).
