Distributed energy resources are consumer-owned devices that can generate such as rooftop solar or store electricity such as batteries and electric vehicles, or have 'smart' capabilities to actively manage energy usage like air conditioners and pool pumps.
The register comes at a time when Australia's energy ecosystem is rapidly transforming, according to AEMO executive general manager of emerging markets Violette Mouchaileh.
The register will be used to help AEMO understand the location and operational capability of DERs installed across the country.
"More and more Australians are investing in distribute energy devices, creating an opportunity to develop a world-leading system that harnesses electricity and energy-related services from DER in homes throughout Australia," Mouchaileh said.
"With increased knowledge of DER, AEMO can better manage the grid and ensure that consumer-led energy investments support energy system reliability and security, while maximising value for Australia's energy consumers."
With the new register now in place, AEMO will have the ability to forecast, plan and operate the grid more efficiently. This could lead to cheaper electricity prices, according to the operator.
The register also has the added benefit of allowing AEMO to better predict major outages and disruptions, and subsequently use DERs to support the grid during these events.
