This study investigates the role of infrastructure maintenance in addressing persistent electricity outages in the eThekwini Municipality, in Metropolitan Municipality in KwaZulu Natal, South Africa.  The research identifies that aging infrastructure, poor maintenance practices, and inadequate resource allocation are significant contributors to the rising frequency and duration of power disruptions across the municipality.  The impact of these outages includes economic losses, traffic disruptions, increased crime, and health risks, particularly for residents reliant on home-based medical care.  The study adopted a Systematic Literature Review (SLR) methodology, using thematic analysis to identify recurring patterns, themes, and knowledge gaps related to electricity infrastructure maintenance. Key findings revealed that poor planning, limited budgetary support, skills shortages, infrastructure vandalism, and theft exacerbate the crisis.  The research achieved its objectives by highlighting the relationship between infrastructure reliability and effective maintenance practices its father proposed a set off extendable recommendations including increased investment and preventative maintenance workforce training the adoption of smart grid technologies and community engagement to reduce vandalism and illegal connections these strategies aim to improve network reliability and service delivery while addressing the social political tensions that result from frequent power failures.

This paper examined the effect of power supply and the performances of Small and Medium Scale Enterprises (SMEs). In doing this, the paper used durations of public power supply, bills paid for public power and cost paid for private power supply as measures of power supply on the performances index of the SMEs in Port Harcourt. The performance indexes are employed in the models as the dependent variables while the power supply indexes are the explanatory variables. The data were sourced primarily through a well-structured questionnaire and the samples determined by the Cochran sampling techniques. The data were analyzed with the Qualitative Respond Model. It was revealed that a lower duration of public power supply significantly reduces the profitability, productivity and revenue, as well as the storage of products of the SMSEs, examined. Hence, the study recommended among others that there is a need to allocate more electric power to the industrial area of Rivers state- Port Harcourt, especially in the day light to encourage productivity, profitability and employment generation in the state.
