The National Low-Voltage Feeder Taxonomy Study aims to produce the first national low-voltage network taxonomy that outlines the real-world characteristics of the distribution system.

Depicting how low voltage power flows through the system will help with the design and assessment of the technologies and systems that can maximise the hosting capacity of distributed energy resources (DER) across Australia. It will also enable users to test the value proposition of innovative technological solutions by highlighting how they contribute to the stability, reliability and performance of networks across Australia.

How the project works

The CSIRO will work with Energy Networks Australia and distributed network service providers across Australia to collect data and information on the state of the low-voltage network. The CSIRO will coordinate the data and develop a standard representation of low-voltage network characteristics for Australia, and a distributed energy resources model. The project will result in the publication of the final low-voltage taxonomy power-flow models for use by the energy sector through the Energy Use Data Model (EUDM).

Area of innovation

The National Low-Voltage Feeder Taxonomy Study project identifies ways to reduce barriers to renewable energy uptake by providing the dataset and tools to move towards evidence-based hosting capacity limits. By providing rich low-voltage network data for free to the wider community, the project grows the capacity for industry, researchers and decision makers to explore the relationship between emerging distributed renewable energy technologies and the operation and performance of Australia’s electricity distribution system.


This project will produce the first national low-voltage network taxonomy that clearly articulates the real-world characteristics of the distribution system in relation to the impact of higher levels of solar PV penetration. The grid stands to benefit from efficiently deployed demand response and distributed storage. It also provides the ability for industry to test how their distributed energy technologies interact with, improve and add value to Australia’s low voltage networks.

Plotting next steps in distributed energy transformation

As Australians embrace rooftop solar at world-leading rates, work is underway to create a modern, fairer electricity system for the future.

$9.6 million to support distributed energy revolution

To support the transition to an electricity network that is increasingly powered by small-scale energy assets, ARENA has announced $9.6 million funding for 12 new projects and studies.

What are distributed energy resources and how do they work?

According to the twentieth century model of energy distribution, large power plants fuelled by coal, hydro or gas, generated electricity that was distributed via a centralised grid.
