Solar powered light emitting diode distribution in developing countries: An assessment of potential distribution sites in rural Cambodia using network analyses

The objective of this research is to use geographic information systems and spatial analyses to create a template for distributing lighting, particularly light emitting diodes, in developing countries. Approximately 1.6 billion people do not have access to traditional electrical systems; therefore, a significant number of people do not have access to safe, efficient, and inexpensive lighting technologies. This research addresses the need for lighting in one developing country. As an introductory case study area for the distribution of lighting products, Cambodia has a population that is considerable, rural, and without electricity. In addition, a significant percentage of Cambodia’s population will not have access to grid-quality electricity by 2030. To help alleviate this lighting deficiency, eliminate inappropriate distribution areas, and create a list of potential locations, the authors use geographic information system techniques to address four site-specific characteristics (grid electricity access, water inundation potential, hazardous landmine locations, and extreme poverty levels). To select among potential locations, the authors combine spatial analyses, service area delineations, and origin-destination cost matrices into a heuristic method for determining one location. These analyses identify the commune of Kantreang as the most appropriate location for lighting distribution.
