Transmission Company of Nigeria (TCN) on Thursday said it had successfully completed the installation and commissioning of two 66MVA 132/33kV power transformers in its Katampe and Alagbon transmission stations in Abuja and Lagos, respectively.
TCN in a statement signed by Ndidi Mbah, who is the company’s assistant general manager, public affairs, said the 132kV voltage level section of the Katampe sub-station, which operates with 2x60MVA capacity transformers, had in the past six weeks functioned with only one 60MVA 132/33kV power transformer.
The government-held power company said the Katampe facility suffered low performance because its second transformer had developed an internal fault, which eventually necessitated its replacement.
This resulted in load shedding experiences in areas within the Federal Capital Territory, such as Gwarimpa, Jabi, Lifecamp, Maitama and Wuse II, beginning from March 1 to April 10, 2017.
With the successful installation and energising of a 66MVA 132/33kV power transformer at Katampe by TCN engineers on Tuesday April 11, the company noted that the bulk load wheeling capacity of the transmission sub-station at 132kV voltage level increased from 120MVA to 126MVA.
This means that the substation now has the capability to wheel power at full capacity across distribution load centres.
Also, with the installation and commissioning of a 66MVA 132/33kV power transformer last week at the Alagbon transmission station, Ikoyi, the station now has a total of 3x60MVA and 2x66MVA power transformers, bringing the total capacity of the substation to 312MVA on 132kV voltage level.
Consequently, TCN said, there has been an improved power supply in Lagos State, particularly around Ikoyi, Victoria Island, Dolfin Estate and Marina.
TCN also reiterated its resolve to continue to further expand its grid capacity and ensure that it continues to efficiently move bulk electricity from generating companies to distribution companies nationwide.
