Energy is the bedrock of development and a necessary derivative to improve the quality of life in unserved communities of sub-Saharan Africa. However, over 500 million people in rural areas of sub-Saharan Africa continue to lack access to energy. The extension of the National grid to sparsely populated rural communities incur high extension costs and is economically unviable. Renewable off-grid solutions such as solar mini-grids offer a faster and more feasible approach to energy access in rural communities. In addition to basic lighting, a range of social and economic benefits which include improved healthcare services, education, security, and economic prospects are expected to uplift existing limitations. Conceptually, the IEA’s definition of energy access offers a holistic and fundamental insight into factors that influence effective energy access, entailing that a base connection is not sufficient to improve a household’s quality of life because the dynamics of development and electrification in remote communities are complex and involve many underlying forces. Hence, a one-way linear assessment of impacts is insufficient as projections rarely match reality. Successful deployment of off-grid systems requires a conducive enabling environment, which includes supportive government policies, access to financing, and opportunities for further investment. This review paper revisits the current state of energy access in sub-Saharan Africa through the lens of a detailed outlook aimed at highlighting the factors that challenge socio-economic opportunities, thereby informing energy policies and investments in off-grid rural electrification. It provides an insight into the current energy situation of rural electrification across countries in SSA. The findings suggest that renewable off-grid technologies can be a transformative technology for rural electrification but must be accompanied by holistic development strategies to maximize its benefits for unserved communities.
