Decentralised Energy Exchange (deX) is a prototype online marketplace that will provide a way for households and businesses with rooftop solar and battery storage systems to be paid for allowing electricity network businesses to access their rooftop solar and stored electricity to strengthen the grid.


The Australian electricity market is being challenged by significant change, and is evolving quickly away from a traditional electricity model based on large power generators and long networks. Innovative energy products and services are rapidly emerging that are giving consumers greater choice and control over their relationship with the energy market, including how their electricity is delivered and consumed.

A good example of this is the use in Australian homes of rooftop solar and battery storage systems, also known as distributed energy resources (DER).

This trend is expected to continue, creating a complex, less predictable and more interactive electricity market where the old ways of managing the power system may no longer work.

However, if harnessed correctly, the power generated and stored by Australian households and businesses can help to strengthen the grid, making it more secure and reliable.

Project innovation

The Project aims to increase the value of renewables by making it possible for the owners of DER (solar PV, batteries and demand response) to engage in market transactions with electricity network businesses who will pay.

Network businesses can use this power to strengthen the grid, and to postpone the construction of costly additional networks, benefitting all consumers through reduced electricity network bills.

This will be achieved through deX, a world-first online exchange platform for buying and selling grid-services such as power from DERs. deX is being developed with open-source software, drawing on the knowledge of leading technology businesses, energy start-ups and electricity market participants.

The project will trial the use of deX and test how an online marketplace for buying and selling power from DER would be used by customers and energy technology businesses.

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.

$12.5 million boost to virtual power plants

Nearly $12.5 million in funding for two projects will aim to improve the way that rooftop solar and other distributed energy resources (DER) are integrated into the electricity system.

deX: buy and sell electricity

deX is a new way to buy and sell electricity in Australia.

Revolutionising the grid: ARENA invests in Adelaide’s second virtual power plant

Extreme heatwaves put tremendous pressure on the electricity grid as demand for energy outstrips supply. As temperatures soared above 40 degrees in Adelaide in February 2017, a blackout caused by load shedding left 40,000 households without power for over half an hour.

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.

Virtual power plants and digital energy marketplaces. These are some of the less tangible, unseen elements of the energy revolution yet they’re central to Bruce Thompson’s working life.
