Abstract
Losses are always present in every power distribution system from the source of supply to the point of utilization. The Nigerian electricity industry experiences so many challenges which contribute to the poor electric power supply to the citizens and many losses to the industry. The purpose of this dissertation work is to evaluate technical and commercial losses on power distribution networks in Nigeria using Statistical Analytical Method with Microsoft excel. The procedures followed in order to achieve the purpose of this work centered on the history of power sectors (Generation, Transmission and Distribution) in Nigeria, the theoretical review and the review of previous work done on the topic and different methods used to achieve the results. This work also centered on the data collected from a power distribution industry and its presentation, distribution loss equations and percentage distribution losses, calculations made on the 11kV distribution feeders and its billing efficiency. Monthly technical and commercial revenue losses and its net revenue losses for a period of one year were achieved. The percentage distribution losses and a chart of distribution losses against the supplied energy on the feeder were also achieved in this work with the challenges encountered. At the end of the work, summary of findings and conclusions were drawn with better contributions and recommendations to improve power industries in Nigeria.

Presentation of Data The results of these six 11 feeders obtained for a period of one year; distribution losses and its percentage losses, technical losses %h, non-technical losses %h and its percentage losses, monthly revenue losses and total annual revenue losses are stated below
It is observed that the evaluated technical loss between 2017-2018 gave 6634805.34 %* #204,484,700.6 for Glass factory network, 6946517.28 %* #214,091,662.60 for
Summary
Electric power growth in Nigeria started in the year 1896 when the earliest electricity producing plant was set up in Lagos state. From until 1929, the Nigeria Electric Supply Company (NESCO) was created as the first power utility company. After twenty-two years (22yrs), the Electric Corporation of Nigeria (ECN) was formed to inherit the assets of Nigeria Electric Supply Company and thereby took the responsibility to generate and distribute electric power to the entire nation. On carrying out the functions, the ECN believed that the electric power supply would on a very good day be available to the whole Nigerians because more power stations were being constructed [18].
