The term mini-grid refers to (relatively small) electric networks that are used to distribute alternate electric current within a village or neighbourhood. Such distribution solutions are mostly used in areas that are remote from national or regional grids.

Mini-grids are usually supplied by a single power generation station (e.g. Micro-Hydro power plant, Wind turbine, combustion engine running on Biogas or a Photovoltaic array). However, the combination of two or more generation technologies (hybrid power systems) attracts greater interest, as this is an option to improve the reliability of the electricity supply.
