Utilities are infrastructures such as electricity, water, telephone etc that provide a common good for individual and the society. Utility networks in a country are vital for the proper and smooth functioning of the modern society. A breakdown of the services of these networks can cause serious economic damage. This study focuses on proper working of electricity distribution infrastructure that can only be assessed and monitored by using Geographic Information System. To accomplish this, geometric data on electricity distribution network in the study area was acquired which involved updating the existing map of the area with GPS observation, georeferencing and digitizing the map. Attribute data was acquired through questionnaire and oral interview. Designing and creation of database for electricity distribution in the study area was then carried out using relational database management approach. Spatial analyses were used to solve spatial problems such as getting the locations of the transformers and the electricity poles, identifying where faults are which aid in decision making and in proper keeping of records. Geometric and Attribute databases were linked using the ArcGIS 9.3 which was also used for Spatial Analyses and information presentation. The result of the analysesrevealed that 113 and 359 buildings are connected to transformers 1 and 2 respectively. 64 buildings use prepaid meter while 121 buildings use analog meter. Buffering operation was also utilized in this project to determine buildings that contravene the setback rule of 6m. Only one of such buildings exists within the study area. Best route analysis was also performed from a building to transformer 2 in case of any fault or fire outbreak that affects electrical facility or buildings. It was recommended that Ibadan Electricity Distribution Company (IBEDC) should establish GIS departments in all its sections and divisions to be handled by competent personnel who are versatile in using GIS software and training and retraining of IBEDC staff working in the department of Geoinformation should also be encouraged especially in areas of computer knowledge and in the use of GIS software.
