Integrating Energy Storage Systems (ESS) into the NEM

On 23 August 2019, AEMO submitted its Integrating Energy Storage Systems into the NEM rule change proposal to the AEMC. Relevant documents can be found below.

This rule change proposal seeks to more efficiently accommodate increasing numbers of grid-scale connections where bi-directional electricity flows occur and business models where a mix of technology types are connecting behind a connection point.

AEMO proposes to create a new registered participant category, termed a Bi-directional Resource Provider, in Chapter 2 and integrate this through the rest of the NER. A person with a stand-alone ESS or ‘hybrid’ facility would register and participate under this new category. 

For further information on AEMO’s rule change proposal stakeholders can refer to the key documents below and will be available on the AEMC’s website.
