THE Transmission Company of Nigeria, TCN, has reinstated that localising tripping in the power sector chain is not the company’s affair.
This is coming against the backdrop of the recent allegation by Benin Electricity Distribution Company, BEDC, allegation that the NationalGrid was highly unstable, with over 2,000 tripping in its network between January and July 2018.
Tripping occurs when the power grid experiences a fault or overload which causes protection switch operation and subsequent interruption in power supply. The causes of power grid trips could be short circuits in power systems, overloading by too large power consumption or failure of generation in power plants.
However, the TCN in a statement signed by the General Manager, Public Affairs, Mrs. Ndidi Mbah, noted that, “The alleged statement was clearly misleading because in the subsequent part of the same report, BEDC claimed significant improvement in its services which could not have been possible if the National Grid was weak as alleged.”
She also stated that, the BEDC has no imbedded generation hence it depends entirely on the National Grid and could not have recorded such improvement if the National Grid has not also improved.
The statement reads: “Since BEDC does not have embedded generation and does not own its own transmission network, achievements like improved electricity supply to over 54 communities, provision of 24-hour supply covering over 20km in Asaba among others though commendable, clearly cannot happen if the National Grid was as problematic as alleged in the report.
“TCN has good working relationship with BEDC Management, we are working towards improving power supply to BEDC consumers.TCN therefore will not join issues nor engage in unnecessary blame game with BEDC; however, for the sake of clarity, most of the so called 2,000 tripping were actually on33/11kV feeders in BEDC’s network due to faults.
“Despite significant improvement recorded by the company within the last one and half years, there are still issues being addressed by its Transmission Rehabilitation and Expansion Program supported by several Multilateral and Bilateral donors.
“There are also pressing issues in BEDC which being addressed, such as the 40MVA transformer issue at Oghara caused by failure of NNDC to comply with TCN specifications.”
The statement also revealed that TCN never directed BEDC to reduce load due to Transmission capability as alleged in the report. Infact, it is common knowledge that load reduction is directly related to inability of DISCO’s nationwide to take the load.”
