Standalone System

Meaning statusEstablishedSource recordDirect document linkedWhy these are different

Definition

A standalone system is an autonomous energy installation that operates without connection to an electricity grid, combining generation (typically solar PV, sometimes wind or diesel hybrid), battery storage and power management to serve a home, institution or facility. The category spans pico-products (solar lanterns), solar home systems, and larger standalone power systems for telecom towers, clinics and remote properties, and is one of the three recognised routes to electricity access alongside grid extension and mini-grids.

Overview

How it is used

The category structures energy access planning (least-cost geospatial modelling), off-grid regulation, humanitarian energy provision and rural development programmes.

Why it matters

Standalone systems made electricity access a retail product rather than a grid engineering project — the key that opened the last mile.
