Grid systems are key focal points for energy debates in the Global South. Off-and on-grid realities, with a plethora of microgrid systems in between, exist simultaneously with differing under-explored consequences for rights, responsibilities, opportunities and constraints. We argue that a conceptualisation around macroand micro-levels of justice helps to elucidate this complexity. A comparative philosophical approach ensues through a spatial exploration of justice in relation to the Democratic Republic of Congo (DRC) and the grid systems derived from hydropower. Original qualitative data is presented, analysed and reflected upon with concluding insights into conducting energy justice in the Global South.
