You can't transform the way energy is produced, distributed and traded without answering a few key questions. Find answers to common questions below.

1. Introducing deX

What is deX?

Conceptually, deX is an open exchange where energy capacity can be transacted between businesses, households, communities and utilities.

Practically, deX is a software platform that helps to drive coordinated development implementation of distributed energy resources (DERs) like solar panels and batteries into electricity markets.

Functionally, deX brings DERs online to deX participants, making them visible in the network and dispatchable when required. Agreements can be formed and capacity from DERs can be aggregated.

What does deX stand for?

The Decentralised Energy eXchange.

What does the deX platform help me do?

Like any marketplace, deX facilitates the exchange between various market participants. deX lists buyers and sellers, records agreements between them, manages event handling and ultimately verifies whether both parties met their obligations.

With deX you can:

  • Publish your energy capacity requirements
  • Respond to an energy tender
  • Create contracts ready for energy events
  • Install and register deX ready devices
  • Aggregate devices
  • Dispatch devices for an energy event
  • Validate dispatches
  • Settle energy transactions

When would I consider using deX?

As a electricity network operator, retailer or governing body there are are a whole range of circumstances that deX can help with. For example;

  • High DER penetration especially if uncoordinated or not visible to the network/government
  • The network is difficult or expensive to upgrade especially residential low voltage
  • If network is forecasting high network capital expenditure markets
  • The area is seeing ageing infrastructure
  • Centralised energy generation no longer makes economic sense. Traditional generation no longer able to secure investments both public and private.
  • High peak demand growth on the system
  • Customers are frustrated at energy providers who are installing increasing amounts of battery and solar systems (voting against traditional generation by doing).
  • Government/regulators wants networks to innovate

Who is behind deX?

The deX platform is an initiative of global energy-tech company GreenSync in collaboration with leading energy industry partners and policy makers and regulators to develop the platform.

2. The deX pilot

What is the deX pilot?

Australian Renewable Energy Agency (ARENA’s) A-Lab provided $450K to technology partner GreenSync for the design and build of a digital exchange for DER’s.

The pilot saw the project team test how an online marketplace for trading capacity from DER’s would be used by customers, utilities and energy technology businesses. Two experiment sites were selected, the Mornington Peninsula and the ACT.

The pilot established a reference group with leading academic and government agencies to ensure independent review and effective knowledge sharing.

Who are the pilot project partners?

3. How to get involved

I am a network utility, energy retailer and or a technology vendor and want to become a partner, what next?

Your first step is to express your organisations interest in becoming a partner.

I am a homeowner and would like to participate in deX. How do I become involved?

We understand that you are excited about deX—we are too. Unfortunately, the deX team are not equipped to manage enquiries from homeowners just yet.

The best way for you to get involved is to contact your energy retailer who will be able to walk you through the options available for your home. Or you can subscribe to deX newsletter to stay up to date on deX news.

What does it mean when technology is deX Ready, deX Registered or deX Contracted?

deX Ready

Being deX Ready means a device is certified to work with the deX. The deX Ready specification looks at;

  • the type of device
  • the device’s energy characteristics
  • the device’s communication and control ability.

A deX Ready device has the potential to be registered, connected and dispatched using the deX.

deX Registered

A deX Registered device has been installed and information on its characteristics, location, and National Meter Number (NMI) have been recorded on the deX platform. The device has been tested to confirm it is able to be communicated with and controlled.

deX Contracted

deX Contracted defines the agreement(s) between a device owner and the person or organisation buying the capacity. This contract stipulates the terms and conditions associated with the registered device.

4. What can deX do

Can deX provide firm capacity through connected / aggregated DER assets?

Yes, it can, but not just yet. deX provides the ability to see and transact with known assets (and known characteristics). With future API developments, a network will be able to publish a request for services or for energy capacity.  With many devices connected, firmness will come through a portfolio of devices being available. This feature set will continue to develop, providing a level of trust and certainty necessary for network companies, retailers and market operators.

Can deX facilitate real-time transactions?

During the first platform release, deX will facilitate long-term contracts. Over time, with more partners and devices connected to deX, shorter and shorter time-frames will become available in transaction contracts, moving towards real-time capabilities.

5. Roll out

Where will deX first roll out?

deX is rolling out first on the southern tip of the Mornington Peninsula in Victoria (as part of The Community Grid Project).

When will deX be ready in my area?

The deX journey is just starting. We are rolling out in a number of regions of Australia (Victoria, the ACT, Queensland and others), but we are aiming to change this and come to an area near you in the future. Learn more about deX project milestones.

6. The technology

Is deX open source?

All of the communication protocols will be documented and open access for API integration. The deX platform was created by GreenSync and is proprietary technology.

What communication protocols does deX use?

The deX API is a RESTful API (over HTTPS) using JSON payloads.

Does deX require smart-meters to be installed?

While smart meters make things a bit easier for deX, it is not a deal-breaker. We take all meters but would require the installation of additional communications for the distributed energy asset to talk to deX and help with market verification.

Is deX a blockchain-based platform?

No, it’s not. deX is a proprietary software product, created and developed by GreenSync. deX is built to enable integration with other technology vendors – those using block-chain and those not using it.

How is deX different to blockchain?

Blockchain is a ledger and deX is a marketplace. deX’s open API and marketplace allows a range of transaction services, such as blockchain and peer to peer to be hosted. Blockchain and deX can work hand in hand.

7. Policy and social equity

Are there any near-term barriers that you see in the current (Australian) regulatory settings or policy environment?

To date, we have not found barriers to the initial release of deX.
