Investigating the Impact of Electricity Supply Interruptions on the Expansion of Small and Medium Size Enterprises (Smes): A Systematic Literature Review

This paper aims to investigate the factors that impact electricity supply interruptions on small and medium-sized enterprises (SMEs) in Cameroon and the theories used by researchers in preventing electricity supply interruptions. The method used is a systematic literature review of empirical studies on factors responsible for various forms of electricity supply interruptions and their impact on businesses worldwide. The author of this study examined 70 publications from 2012 to 2022 within the scope of the subject and analyzed the factors responsible for interruptions and prevention techniques used to curb the interruption of electricity supply. The results revealed that human factors, technological factors, and atmospheric & environmental factors have impacts on the interruption of electricity supply. Further, the study found that most of the publications on the subject were case studies (74%), while the remaining studies comprised Quantitative studies (19%), Qualitative studies (7%), and 0% for mixed studies research. It was also revealed that technological, human, atmospheric, and environmental factors are more responsible for electricity supply interruptions in developing countries than in developed countries. The results imply that electricity network designers need to mitigate electricity interruptions by employing modern techniques. The study recommends that alternative electricity supply sources could be used to help reduce interruptions, especially using other renewable energy sources like solar electrification systems and generators as backup or supplementary systems to enhance the electricity supply.
