I. Introduction
The electricity supply-demand problems have caused a strain on the centralized power entity. Developing countries like South Africa are finding it challenging to meet the desired outcome for both satisfying the customer needs and covering the operational costs [1]. South Africa has one of the highest energy intensities globally compared with only a few countries having higher intensities. South Africa's primary energy consumption per unit of GDP is among the highest in the world [2]. According to [2], South African's history of low electricity prices substantiated to lower energy efficiency compared to the international standards and other countries. In recent years ESKOM is playing a catch-up game to cover the capital and operational costs. Due to these reasons, electricity prices skyrocket each year and encourage users to think of low-scale alternative methods to meet their electricity demand needs at reduced costs.
