ABSTRACT This research project presents a method of planning for the electrical loads requirements using load estimation method rather than measurement method because of its simplicity, flexibility, sustainability and cost reliability and the recommendation of the appropriate transformer size to avoid incessant blow off and damages to 500kVA 11/0.415kV substation even for other substations with related specifications. The proposed electrical model designs of Emiloro Community ,off Oda road was used to show a typical design with 500kVA implemented using AutoCAD 2012 Version Software. It aims at the design of 500kVA, 11/0.415kV substation with respect to voltage and frequency deviation with maximum efficiency and at moderate running and maintenance cost, the required quantities of the major substation components required for implementation of developed electrical model designs were obtained.
