We can provide individuals or businesses with raw historical load data for specific zone substations upon request.

Information will only be provided when Essential Energy deems the request as reasonable, information is available and data is not confidential or commercially sensitive.

Data is collated for a yearly period from 1 October to 30 September - for example – 1 October 2012 to 30 September 2013.

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

The available datasets are updated by 31 December each year.
