UNIDO A mini-grid is a set of small-scale electricity generators interconnected to a distribution network that supplies electricity to a small, localized group of customers and operates independently from the national transmission grid. Mini-grids are a critical tool for achieving universal electricity access. The new Clean Energy Mini-Grid Policy Development Guide aims to help policymakers navigate the renewable mini-grid market, providing them with tools and recommendations on how to approach policies and regulations in this space. The guide outlines the various forms and models that public-private cooperation could take and reflects on the outcomes of policy decisions on mini-grid deployment.
