Abstract
Electrical energy is usually generated long distances from the load centres; therefore, it needs an extensive network of
conductors to bring it to the consumers. Due to the long distance covered by these conductors, power losses occur in the
distribution system. Power losses affect the system's efficiency, reducing grid reliability, voltage instability, needless
switchgear tripping, and blackouts. Power losses could be technical and non-technical. Technical losses are inherent due
to the component on the distribution network; thus, it is unavoidable and can only be reduced, not eliminated. This paper
evaluates the power loss on the 11 kV Igosun distribution feeder, Offa, Kwara State using the backward forward sweep
algorithm implemented in MATLAB platform. The data, extracted from the feeder's topology, were used to calculate the
corresponding real and reactive power load at the respective buses. The results show a total real power loss of 873.5688
kW and a total reactive power loss of 504.3703 kVAR on the feeder. The knowledge of the feeder's power losses will
benefit electric power utilities to improve the quality of the power supply and revenue generation.
