Controlling electrical power losses in transmission and distribution networks in Nigeria

Abstract

Electrical power losses in Transmission and Distribution (T&D) networks in Nigeria have been examined to det-ermine the high technical and non-technical losses associated with the system, and the control measures to man-age the losses. Very long and over-aged T&D lines, unequal phase loads, inadequate reactive compensation and energy theft contributed to the high energy losses in the networks. The measures proposed to control the losses, enhance efficiency and strengthen reliability of the networks were using conductors of appropriate sizes, realig-ning the lines, introducing more substations, undertaking regular energy audit and implementing pre-paid meter-ing systems. The policies on deterring energy theft, meter tampering, fully accounting for energy generated and distributed and strategic marketing of power should be enforced. The re-branding of the Power Holding Comp-pany of Nigeria for satisfactory services would restore confidence of the customers.
