Energy access
Mini-Grid
A local electricity network combining generation, distribution and often storage to supply a defined community, operating independently of or connected to the main 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.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
