Goal
The Integrating Energy Storage Systems (IESS) rule seeks to better integrate storage and hybrid systems into the NEM. As a part of this rule change, the following changes are proposed:
- Introduces a new registration category, the Integrated Resource Resource is individual component assigned to a role for an admin, user, or service account. It defines what the account can do at a system level such as access, view or maintain, and include the actions such as create, read, update, etc. Resources are created and maintained in the SAM database directly, and can be viewed within the IDAM application for creating a role. Provider (IRP Integrated Resource Provider. Any person who owns, controls or operates an integrated resource system connected to a transmission or distribution network must register as an Integrated Resource Provider). The IRP allows storage and hybrids to register and participate in a single Registration Category Generating units modelled in the EAAP are categorised into Baseload, Intermediate or Peaking generation groups. rather than under two different categories.
- Clarity for scheduling obligations that apply to different configurations of hybrid systems. This includes for DC coupled systems (which have different technologies behind a single inverter) allowing them the flexibility to choose whether those technologies are scheduled or semi-scheduled.
- Transferring existing Small Generation Energy Rules Terms Aggregators to the new category and enabling new aggregators of small generating units and/or storage units to register in this category. Market Customers are still able to include small generating and storage units in their portfolios.
- Enabling aggregators registered in this new category to provide market ancillary services from generation and load.
- Amending the framework to recover non-energy costs based on a participant’s consumed and sent out energy over relevant intervals, irrespective of the participant category in which it is registered.
A part of these changes are effective as per the dates below. These include:
- Allowing aggregators of small generating and storage units to provide ancillary services. These changes are effective from 31 March 2023.
- Hybrid systems to use aggregated dispatch conformance (ADC) effective from 08 August 2023.
