AEMO’s DER Register
By 2029, distributed energy resources will be the largest installed capacity of any generation technology in Australia. And on a global scale, Australia is gaining ground in the decentralisation ratio, forecast to overtake Italy and Germany by 2024 and continuing to outpace Japan, Brazil, the US, India and China in coming years. “We live in exciting times” said AEMO’s Scott Chapman at this week’s Smart Energy conference, “we are driving proactive changes to the energy market.”
Those changes have triggered the need for building a two-way electricity system and establishing a two-sided marketplace to trade services from consumers and one that enables open access to essential device information across Australia to gain better visibility of the capacity of distributed energy resources, he said.
“To achieve that, it’s now necessary to integrate a DER register into the system and market to maximise customer value though price greater choice and the provision of a secure and reliable system,” Chapman explained.
AEMO is now on track to launch Australia’s first DER database which will include all forms of small grid-connected generation and storage at the start of December 2019.
“With better knowledge and visibility of DER, AEMO can better manage the grid and ensure that consumer-led energy investments can deliver their expected value to consumers and the energy system,” Scott Chapman said.
The AEMO fact sheet spells out the work with stakeholders across the electricity sector to design the DER Register, agree on DER data sets and data collection processes into the register.
The DER Register database will enable AEMO to:
· Forecast, plan and operate the grid more efficiently, ensuring the system and market can deliver energy at an efficient price for all customers,
· Be more prepared for major disruptions to the system with a greater understanding of how DER assets will behave during these events,
· Prepare the grid for major innovations with DER such as virtual power plants, and enabling customers to consider and participate in new markets with their DER, and
· Allow networks to make better-informed decisions about network investment options in the future as demand changes and DER increases.
The system kicks off from 1 December when the new rules require Network Service Providers to provide information on every small generating or battery system within 20 days of the system commissioning or activation, which will feed into AEMO's DER Register.
The fact sheet goes on to explain the importance of capturing information on the equipment installed on site, data that can be provided through existing processes or straight into AEMO’s portal or via mobile applications.
Systems developed by AEMO are “designed to minimise the effort from DER installers and electrical contractors”.
“The new system and approach represent a change to the way small-scale solar, batteries and other forms of DER are deployed in Australia, but the benefits for all Australian’s will be large,” AEMO says.
Critically, installers will be mostly be asked to confirm information, rather than enter it.
