‘How rehabilitation of key power infrastructure will aid electricity supply’
The Transmission Company of Nigeria (TCN) is expecting improvement in the supply of electricity across the country as the government begins rehabilitation of key power infrastructure.
Specifically, the government-owned agency is expected to rehabilitate and replace old circuit breakers in the nation’s transmission network.
Reportedly, the transmission link has been described as part of the basic challenges facing the wheeling of electricity across the country.
If properly done, experts believe that recurring collapse of the electricity grid may subside as Nigeria’s Osogbo-based national electricity grid has failed electricity consumers more than 128 times since the nation’s power sector was privatised in 2013.
TCN in a release said the project is geared towards further improving bulk power transmission to distribution load centers nationwide.
Circuit Breakers protect power transformers from any abnormal conditions or faults that may occur within or from outside the network. They also provide power supply flexibility in the substations’ switchyard when maintenance work is ongoing, without interrupting bulk power supply to distribution load centres in the grid.
Already, the rehabilitation and replacement work has been officially flagged off at the 37 years old 330/132kV Ajaokuta Substation, Kogi State.
General Manager in charge of Public Affairs at TCN, Ndidi Mbah, said the agency would ensure that all circuit breakers in its network are certified healthy and perform optimally.
According to her, the decision to start with the circuit breakers in Ajaokuta substation was due to the strategic role the substation plays in transmitting bulk electricity to distribution load centers of Abuja Distribution Company and Benin DisCos, covering areas such as; Abuja, Lokoja, Ayangba, Okene, Okpila, and Benin among others.
“TCN’s efforts at rehabilitating the circuit breakers, despite routine maintenance undertaken by in-house engineers, are to ensure that they continue to perform optimally and eliminate any incident of sudden breakdown due to age. The exercise will be extended to all substations in the country whose circuit breakers are 20 years and above,” Mba said.
She said TCN engineers would be working directly with the contractors to ensure hands-on training and practical skills transfer.
Mba said proper retrofitting or replacement of the circuit breakers would ensure that they operate optimally for the next 15 to 20 years.
She said the agency would not relent in its efforts to maintain, repair, and replace power transmission equipment, as well as install new ones to ensure a more stable and efficient transmission of bulk power to the distribution substations nationwide.
