Projects
The EMMS Energy Market Management System (formerly MMS); software, hardware, network and related processes. – Technical Specification – Data Model The definition of the interface to participants of data published by AEMO for gas or electricity. A database conforming to the Data Model can contain a local copy of all current participant-specific data recorded in the main database. The Data Model includes database tables, indexes, and primary keys. v5.2 – March 2023 provides the data model table details for the following projects.
NEM reform
AEMO Australian Energy Market Operator, together with industry, is delivering a number of the Energy The unit must be a generator for the service type: ‘energy’. Loads cannot bid for mandatory restrictions capacity. Security Board’s (ESB) Post 2025 and other energy market reforms. The reforms provide for changes to key elements of the market design to facilitate a transition towards a modern energy system.
For details, see NEM Reform Program.
Direction and RERT Recovery Data Reconciliation
For release May 2023.
Changes to reconcile the Direction/RERT Recovery Data:
- Calculate the Excluded Energy from Scheduled Loads and capture it separately.
- Add extra participant information.
- Publish new and modified information to the participants in the Data Model. For details, see Data model changes summary.
Fast Frequency Response (FFR)
Part of NEM2025 for release 9 October 2023.
Fast frequency response (FFR Fast Frequency Response) introduces two new market ancillary services: very fast raise and very fast lower. Fast frequency response refers to the delivery of a rapid active power increase or decrease by generation or load in a time frame of two seconds or less, to correct a supply demand imbalance and assist in managing power system frequency. FFR is a relatively new service offered by inverter-based technologies such as wind, solar photovoltaics (PV), batteries and demand-side resources.
For more information on FFR changes, see Fast frequency response market ancillary service.
Integrating Energy Storage Systems (IESS)
Part of NEM2025 for release August 2023.
The Integrating Energy Storage Systems rule seeks to better integrate storage and hybrid systems into the NEM. There are significant changes to registration and dispatch Energy Rules Terms arrangements as well as in areas such as non-energy cost recovery, performance standards, and participation options for aggregated portfolios of small resources as a part of IESS Integrating Energy Storage Systems.
For details, see Integrating Energy Storage Systems project.
MT PASA
Part of NEM2025 for release October 2023.
Changes for Scheduled and Semi-Scheduled Generators See Relevant Rules or Procedures when submitting MT PASA Medium Term Projected Assessment of System Adequacy. A 24-month supply demand forecast, published weekly, with daily resolution. Offers. For details, see EMMS – Technical Specification – October 2023.
Stand-alone Power Systems (SAPS)
Part of NEM2025 for release May 2023.
Stand-alone power systems are an electricity supply arrangement not physically connected to the national grid. The new framework ensures the customers who receive SAPS Standalone Power Systems retain their existing consumer protections, including access to retail competition and existing reliability standards. As such, individual customers are not disadvantaged where a DNSP Distribution Network Service Provider. A business that owns, operates or controls an electricity distribution network. determined it is more efficient to supply them on a stand-alone basis. The cost savings arising from the use of lower cost stand-alone systems flows through to all distribution network users, through lower network prices.
