Energy access
Mini-Grid
Definition
A mini-grid is a decentralised electricity system — one or more generation sources, a distribution network and consumers within a defined area — that can operate independently of the national grid or in conjunction with it. Generation may be solar PV, small hydro, wind, biomass, diesel or hybrids, increasingly paired with battery storage.

Overview
What it means
Mini-grids serve rural and remote communities where grid extension is uneconomic. Quality of access matters as much as connection: hours of supply, reliability, affordability and capacity for productive use determine real development benefit.
How it is used
Development finance institutions and governments fund mini-grid programmes as a least-cost electrification route under SDG 7; regulators create licensing and tariff frameworks; developers build solar-hybrid village systems.
Why it matters
Hundreds of millions of people lack electricity; mini-grids are often the cheapest way to reach them with clean power, enabling education, health services, enterprise and displacement of kerosene and diesel.
