Abstract

Epileptic power supply is a major problem which has great impact on
socioeconomic development of Nigeria. Power Holding Company of Nigeria (PHCN)
is responsible for power distribution in the country and one of the major
challenges is the haphazard distribution of their facilities, most especially,
electrical transformers. In addition, spatial locations of electrical
transformers and other attribute data are kept using manual approach and in
some cases, the records are not available. This study is aimed at using
Geographic Information System (GIS) to take inventory of PHCN electrical
transformers in Ikorodu district of Lagos, in order to assess their spatial
distribution. The research method adopted includes converting the existing map
of the study area into digital format through scanning and digitizing,
collection of spatial locations of electrical 
transformers’ with GPS receivers and attribute data through social
survey. ArcGIS software was employed to create spatial database for forty two
(42) electrical transformers located in the study area and various spatial analyses such
as query, overlay, buffering, etc. were performed to view the spatial
distribution of PHCN facilities. The spatial database created can be easily
updated from time to time at a fast rate and reduced cost, and without passing
through the whole process of map production. Appropriate recommendations were
made for socioeconomic development of the country and effective management of
the PHCN facilities. The outcome of the study can be adopted in other
developing countries with similar challenges.
