The Transmission Company of Nigeria (TCN) has said that it has completed the construction of a new transmission tower in the Ajah axis of Lagos state.
The newly constructed transmission line has increased the transmission lines capacity on that route, which was 600 Megawatts (MW), by an additional 600 MW, bringing it to a total of 1,200 MW.
This disclosure was made in a public statement issued by the TCN’s General Manager, Public Affairs, Mrs. Ndidi Mbah, on Thursday, March 18, 2021.
Mbah said that TCN has also strung the old and a new 330 kilovolts Egbin – Ajah transmission lines, adding that both lines have been energised.
Mba in her statement said, “The old line was re-energised on March 13 while the new line was energised on March 15. Prior to resuscitation of the second Egbin-Ajah Transmission Line, the Aja 330/132/33kV Substation operated through a single circuit 330kV transmission line. Within the period, the lone 330kV line had a maximum capacity of 600MW.’’
Mbah said with the resuscitation of the second 330kV line and the diversion of both lines along the new tower line route, the transmission lines capacity has doubled.
She said that with the new 330kV line, TCN has fulfilled the N-1 reliability criteria on that line route, providing redundancy.
Mbah said that each of the lines can serve as ‘back-up’ for the other during maintenance as this has increased transmission efficiency and reduced downtime on that line route.
She said, “The 13.8-kilometre transmission line receives power supply from Egbin 330kV Transmission Substation and supplies the Ajah 330kV Substation; Lekki 330kV Substation and Alagbon 330kV Transmission Substation.
“The additional 330kV transmission line equally means that more bulk power is now supplied to the substations of Eko Electricity Distribution Company taking supply from the listed transmission sub-stations.’’
