The Transmission Company of Nigeria said that it has increased the ability of Eko electricity distribution company (Disco) to take more electricity from its transmission network to supply its customers.
TCN said in a statement from its General Manager, Public Affairs, Mrs. Seun Olangunju, that its transformer capacity in its Ajah substation has been upgraded with an additional 60 megavolt amperes (MVA) 132/33kV power transformer.
It explained that the transformer was successfully refurbished, installed and commissioned into service on July 11, 2017, to improve the station transformer capacity at 132kV level to 220MVA.
Olagunju, said in the statement that the newly installed 60MVA 132/33kV power transformer replaced an old 60MVA transformer which failed in the substation in August, 2016.
She added that the TCN has also commenced installation of a 60MVA 132/33kV mobile power transformer in the same station to further increase transmission capacity in the area.
“Installation works have reached advanced stage and on completion, the mobile transformer would increase the transmission capacity in the substation to 280MW, which is above the distribution load requirement in the area.
“The increased capacity of the Ajah transmission substation means that additional power is now available to be wheeled to distribution load centers supplying electricity to Ajah and environs. TCN pledges to continue to work towards expanding and ensuring the nation’s grid stability,” Olagunju explained.
The TCN also said that it has successfully restored electricity supply to Birinin Gwari and Yauri in Kaduna, and Kebbi States respectively, after the collapse of a transmission tower that conveys power to the states.
It said that its 132kV transmission tower no 183, between Tegina and Kontagora in Niger State, had recently collapsed from severe flashflood caused by heavy rainfall which eroded the base of the transmission tower, despite remedial works carried out to fortify its foundation.
TCN noted that its engineering crew were immediately mobilised to the site to construct transmission line by-pass towers that would ensure supply of electricity to the areas affected by the incident. The transmission line by-pass towers, were successfully erected and power supply restored to Birinin Gwari and Yauri.
It further stated that its engineering crew were still working to restore its primary circuit breaker damaged by angry youths in Tegina substation, to enable it supply from the substation, adding that power supply to Kontagora substation would also be restored as soon as it completes repairs on the stations circuit breaker.
With the transmission line by-pass tower, TCN said that it has resumed normal transmission of electricity to Yauri and Birnin Gwari Emirates under Kaduna Disco.
Similarly, it explained that it has commissioned a new 40MVA transformer at its 132/33kV transmission sub-station at Mayo-Belwa, to improve power supply.
The newly constructed station it saw was energised to improve transmission capacity in Yola sub-region by about 32 megawatts (MW).
“The Mayo-Belwa 132/33kV substation connects Ngurore 33kV Feeder and Mayo-Belwa 33kV feeder thus extending power supply to Jada, Toungo, Ganye and several other towns and villages in Taraba State. Prior to the construction of the new station, Mayo-Belwa received power supply from Yola transmission station, through the 33kV Mayo-Belwa/ Numan feeder,” added Olagunju in the statement.
