Indicative timetable

As required by the National Electricity Rules (NER), AER is preparing to undertake the next transmission determination for the Victorian electricity transmission network service provider (TNSP) — AusNet Services. The AER’s transmission determination will cover the next regulatory control period (1 April 2027 to 31 March 2032). AusNet Services' regulatory proposal is due by 31 October 2025.

The AER must publish a framework and approach paper in anticipation of the transmission determination. The framework and approach paper will set out the AER’s likely approach in the transmission determination for AusNet Services on such matters as:

  • application of incentive schemes
  • expenditure forecast assessment guidelines, and
  • whether depreciation will be based on forecast or actual capital expenditure.

Interested parties are encouraged to consider the key dates.
