Decentralised Energy Exchange (deX)
- $450k Funded by ARENA
- $983k Total project cost
Summary
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.
Need
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.

This report will focus on the technology vendor led approach to registering DER in deX and, specifically, on the insights gained from a recent customer enrolment campaign, in partnership with Enphase.
Report: deX Project Progress Report
deX is a digital platform that allows electricity networks to better coordinate the increasing volume of distributed energy resources in the electricity grid, while helping consumers get more value from assets such as solar, batteries and electric vehicles.

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.

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.
