Raw historical load data for zone substations is provided where information is available, and data is not confidential or commercially sensitive.

Information includes zone substation name, the date and time of the measurement in Australian Eastern Standard Time (AEST), kW and kVAr measurements in half hourly intervals.

Data is collated for a yearly period from 1 October to 30 September. Each year is available as a separate compressed download, each zip containing a single .csv file of all zone substations.

You can find zone substation names in our Distribution Annual Planning Report.

The available datasets are updated by 31 December each year.
