Mini-grids - Wikipedia mini-grid is an off-grid electricity distribution network involving small-scale electricity generation. Often conflated with microgrids, a mini-grid is sometimes defined as having a power rating less than 11kW and as being disconnected from utility-scale grids. The United Nations Framework Convention on Climate Change (UNFCCC) defines a mini-grid with a power rating below 15MW and ...
