Generation information pages

Prior to the 18 July 2019 update, separate data files were published for each region, as shown in the links in the following table.  

From 18 July 2019, the data will be published within 1 consolidated 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.

The consolidated file includes many enhancements, in response to requests from external stakeholders during the revision of the Generator Survey process, which became effective from March 2019.

The enhancements include:

• the publication of Expected Closure Year/Date year for existing scheduled and semi-scheduled generators in the NEM,
• the ‘Summary’ chart and associated data table now enabling the user to select:
  • either 1 or all NEM Demand Regions, and / or
  • 1 or a select combination of Generator Dispatch Type(s),
• presentation of the ‘Change Log’ in a tabular format for easier filtering of entries,
• merging of the 3 previously separate 'Existing S & SS Generation', 'Existing NS Generation', and 'New Developments' data tables into 1 'Existing Generation and New Developments' data table,
• merging of the 2 previously separate 'Summer Scheduled Capacities' and 'Winter Scheduled Capacities' data tables into 1 'Scheduled Capacities' data table,
  the inclusion of many new data fields within the data tables mentioned above, to provide greater transparency to the NEM, and easier analysis of the data, for all users.

Expected closure date/year

The data file publishes the expected closure date/year for scheduled and semi-scheduled generators in the NEM. Data is expected to be updated when AEMO receives notification of major changes to closure dates.
