The Transmission Company of Nigeria has announced the successful completion of a new transmission tower in Ajah, Lagos.
It also added that the old 330 kilovolts Egbin – Ajah transmission line as well as a new one has been strung together and energized. They were energized on Saturday 13th March, 2021 and Monday15th March, 2021 respectively.
The statement signed by the General Manager, Public Affairs, Mrs Ndidi Mbah, me explained that the new line increased the transmission lines capacity on the route by 600 megawatts (MW) bringing it to a total of 1,200MW.
Prior to resuscitation of the second Egbin-Ajah Transmission Line, the Aja 330/132/33kV Substation operated through a single circuit 330kV transmission line, after the second line was isolated in 2013, due to Ajah GIS substation insulation failure. Within the period, the lone 330kV line had a maximum capacity of 600MW, but with the resuscitation of the second 330kV line and the diversion of both lines along the new tower line route, the transmission lines capacity doubled.
According to the statement, with the new 330kV line, TCN has fulfilled the N-1 reliability criteria on that line route, providing redundancy. Each of the lines can serve as ‘back-up’ for the other during maintenance thereby translating to increased transmission efficiency and reduced downtime on that line route.
“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 form the listed transmission substations.
