Egbin ? Ajah transmission lines and tower construction in Lagos Nigeria complete

The construction of 330 kilovolts Egbin – Ajah transmission lines and transmission tower at Ajah, in Lagos, Nigeria is complete according to the Transmission Company of Nigeria (TCN).

TCN is one of the 18 companies that was unbundled from the defunct Power Holding Company of Nigeria (PHCN) back in April 2004 and is a product of a merger of the transmission and system operations parts of PHCN. The company’s main job is to manage the electricity transmission network in the West African country.

According to the General Manager of Public Affairs, at TCN, Mrs.  Ndidi Mbah, both the old and the newly build transmission lines have been energized. The old line was re-energized on Saturday the 13th of March this year while the new line was energized two days later, on the 15th of March to be precise.

Mrs. Mbah explained that the new line increased the transmission capacity on that route by 600 megawatts (MW) bringing it to a total of 1,200MW.

N-1 reliability criteria on Egbin – Ajah route fulfilled

With the new 330kV line, according to Mrs. Mbah, TCN has fulfilled the N-1 reliability criteria on that line route. Each of the lines (the old and the new) can serve as a ‘back-up’ for the other for example during maintenance. This will significantly increase transmission efficiency and reduce downtime on that line route.

“The 13.8-kilometer route receives power supply from Egbin 330kV Transmission Substation and supplies the Ajah 330kV Substation, the Lekki 330kV Substation, and the Alagbon 330kV Transmission Substation.

The additional 330kV transmission line means that more bulk power will now be supplied to the substations of Eko Electricity Distribution Company taking supply from the listed transmission substations,” she concluded.
