Every month we publish small-scale renewable energy installation data files.

These data files provide a list of:

  • small generation units (small-scale solar panel, wind and hydro systems) and kilowatt (kW) capacity by installed postcode
  • solar water heaters and air source heat pumps by installed postcode.

The data represents all systems that have had certificates validly created against them. The data includes new installations, upgrades to existing systems and stand-alone (off-grid) systems.

This data is not publicly available via the REC Registry and does not include systems that are pending registration or have been failed.

Note: A 12-month creation period for registered persons to create small-scale technology certificates applies under the Renewable Energy (Electricity) Act 2000. Therefore, the 2024 and 2025 figures will continue to rise due to the 12-month creation period.

Total investment in wind and solar generation capacity, including Small-scale Renewable Energy Scheme capacity for 2016 to 2025 is available under large-scale renewable energy data.

Summary of postcode data

This data is current as at 31 March 2025.

The collection of grid-connected installations with disclosed battery data commenced in September 2014.

The public register of small-scale technology certificates in the REC Registry allows users to search and view details of small-scale technology certificate creation.

New file structure including historical data

The historical month-to-month downloadable data for 2001 to present is now available in a new format.

We have changed the format of the current and historical Small-scale Renewable Energy Scheme postcode data. Instead of hundreds of historical individual spreadsheets, we have consolidated the data to present all current and historical data into 4 spreadsheets.

Each column will show data for a month and there are no more aggregated data columns.

Please note all file names have changed to reflect the new data structure.

This will save time for users by:

  • removing the need to link 20+ files together to create a full month-to-month time series
  • presenting a clearer source of truth with no data overlap between our historical data files.

Please email enquiries@cer.gov.au if you have any questions.
