The aim of this paper was to assess the socio-economic impact of access to solar mini-grids on the livelihoods of end-users in Zambia. The study employed a qualitative and quantitative research design, utilising control and experimental groups. The study demonstrated that access to solar minigrids contributed to the reduction of the average monthly household lighting energy expenditure. Additionally, the access to solar min-grids also positively contributed to the increase in household income through the engagement in different economic activities.
