Power systems are extremely complex systems, comprising of generators, transformers, buses, lines, loads (motor) and the associated protection & control devices/circuitry. Power system engineering or operations in Nigeria deals with the business of generation, transmission and distribution of electric power (electricity). Each components of the power system of generation, transmission & distributions have losses inherent in them which affect the efficiency &reliability of the entire power system operations. Therefore, there is an urgent need to reduce these losses not just for operational and revenue gain but also for economic growth/infrastructure as a stable & affordable electricity is the backbone of industrialization. This study highlights the various components of Aggregate losses in Distribution Sector; the impact of these distribution losses on power delivered by grid; and offers the way forward to reduce these losses for optimal grid performance and accelerated socio-economic/infrastructural development.
Key words: DISCOs, Electricity, HVDS, Distribution Losses, Power Systems.
