Generation information

This page reports information on the capacity of existing, withdrawn, committed, and proposed generation projects in the National Electricity Market (NEM). AEMO collects generation information reported here from generation industry participants, via a web-based online system, and is committed to publishing updates of information collected every six months, or as required.

Interim Generation Information Guidelines

Purpose and scope

  1. These are the interim generation information guidelines (Guidelines) made under clause 11.117.3(b) of the National Electricity Rules (NER). The interim Guidelines will remain in effect until AEMO publishes generation information guidelines developed in accordance with the rules consultation procedures, to be completed by 31 July 2020 (under NER 11.117.3(a)).
  2. NER clause 3.7F(e) specifies four topics that must be addressed in the generation information guidelines, to which the sections below correspond. These are:
    1. the categories of information to be published on AEMO’s generation information page;
    2. the intervals at which updates to the generation information page will be published;
    3. the manner, timing and format in which key connection information will be provided by transmission network service providers (TNSP) to AEMO; and
    4. guidance regarding the evidence that AEMO may require to register a project developer and NER clause 3.13.3AA(c).
  3. These Guidelines have effect only for the purposes set out in the NER. The NER and the National Electricity Law prevail over these Guidelines to the extent of any inconsistency.

Key Connection Information (KCI)

The following Key Connection Information (KCI) is required to be published on the Generation Information Page under NER 3.7F(3). The information is part of a series of changes to the National Electricity Rules (NER) to improve the transparency of new generation projects in the National Electricity Market (NEM).

If any party has additional information they believe should be included on this generation information page, or believes a change is required to the information currently reported, please direct that information to generation.information@aemo.com.au

From 18 July 2019, the Generation Information data will be published within one consolidated "NEM" data file, and continue to provide information for each region in the NEM about:

  • Existing and committed scheduled and semi-scheduled generation capacities over the next 10 years.
  • Changes and limitations to existing generation.
  • Proposed developments.
  • Existing non-scheduled generation.
  • Expected closure year (values are correct at the time of "NEM" data file publication).

Any updated expected closure years provided following the publication of the “NEM” data file (as per NER 2.2.1(e)(2A)) are found in the "Generating Unit Expected Closure Year" file below.

This file represents the most up to date collection of closure timings.

October 2019 update

Contrary to media reports in October 2019, CS Energy has not changed the retirement date of Callide B that is now recorded in AEMO's 'Generating Unit Expected Closure Year'. The design life of Callide B is 40 years, ending in 2028-29.

AEMO acknowledges the 2018 Integrated System Plan (ISP), published in mid-2018, used a generic NEM-wide coal-fired generation fleet assumed operating life of 50 years from full operation, or announced retirement date, as part of its expedited modelling methodology.

AEMO has been formally advised of Callide B's 40 year design life, and will reflect this timing in the 2019-20 ISP.
