On 2 December 2021 the Australian Energy Market Commission (AEMC) made a Final Determination on the Integrating Energy Storage Systems (IESS) Rule change. The change seeks to better integrate storage and hybrid systems into the National Electricity Market (NEM).

Under the Rule, there will be significant changes to registration and dispatch arrangements as well as in areas such as non-energy cost recovery, performance standards, and participation options for aggregated portfolios of small resources.

High Level Design for the implementation of the IESS Rule Change

The high-level design outlines proposed arrangements for the implementation of the IESS rule change. The purpose of the document is to:

  • Outline AEMO’s system and operational changes, in order to allow for efficient planning of the IESS implementation project.
  • Enable participants and other stakeholders to understand and plan for system, process and operational changes required to implement the Rule Change.
  • Provide an opportunity for feedback from industry on proposed arrangements for the implementation of the IESS rule change.
