Distributed Energy Resource Register

Introducing Australia's world-first DER Register

Australia’s first DER Register launched on 1 March 2020. The DER Register is a database of information about DER devices that is foundational to AEMO’s Distributed Energy Resources (DER) Program.

AEMO is dedicated to sustaining a reliable, secure and affordable energy supply for all Australians. Given the rapid uptake of small-scale energy generation devices (such as rooftop solar PV), AEMO needs visibility over these DER devices to better manage the electricity grid and ensure that consumer-led investments in DER devices deliver their expected value.

The DER Register stores information about a DER device installed on-site at a residential or business location. This information will be requested by Network Services Providers (or network operators) from qualified electrical contractors and solar installers at the time of the DER installation.

The WEM DER Register – coming soon

Large amounts and continuing growth of DER is also prevalent in the Wholesale Electricity Market (WEM). As outlined in the Western Australian Government’s DER Roadmap, AEMO is implementing a DER Register for the WEM to collect and make data available on DER installed across the South West Interconnected System. 

The benefits of the expansion of the DER Register to cover the SWIS are improvements in:

  • Planning where the increased visibility of DER and their associated performance characteristics will increase confidence in planning and design, reducing the need for conservative decisions.
  • Operation of power systems with enhanced load forecasting and modelling capability.
  • DER asset and installation integrity.
  • Data records and reporting.

The WEM DER Register is a collaboration between AEMO, Western Power and the Western Australian Government, and will be launched in 2021. 

For more information on how the WEM DER Register will be implemented, please see the WEM DER Register Information Procedure. 

DER Register Reporting

Under the National Electricity Rules, AEMO has an obligation to provide reports on the number of DER devices installed across the NEM.

The reports section is now available here.

The information included in these reports provides insight into the number of DER devices by region, down to a postcode level where data meets the requirements of AEMO’s privacy policy and the requirements set out in the Rules. For any questions relating to the data, you can contact SupportHub@aemo.com.au

Following the launch of the WEM DER Register, data on DER in the SWIS will also be made publicly available, when combined with NEM data this will provide the first national view of DER devices installed across Australia.

Helpful information for DER installers and other stakeholders

Updating the DER Register

The DER Register is updated with information from DER installers and Network Service Providers or Network Operators. For further information on how to update the DER Register please refer the DER Register Portal.

In WA, electrical contractors will be expected to provide DER data with their Notice of Completion to the Building and Energy Department’s portal, once the system is online during 2021.

Please use Google Chrome to ensure compatibility with the DER Register Installer Portal.
