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This page reports information on the capacity of existing, withdrawn, committed, and proposed generation projects in the National Electricity Market (NEM).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 three months, or as required.

Expected closure years

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.

NEM Generation information publications

Generation information data is published within one consolidated "NEM" data file, and provides 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.

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

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).

Generation Information Guidelines

Purpose and scope

  1. These are the Generation Information Guidelines (Guidelines) made under clause 11.117.3(a) of the National Electricity Rules (NER).
  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.
