Powerlink calculates prices in accordance with the framework set out in the National Electricity Rules (NER) and its pricing methodology.

Powerlink's revenue for owning and operating its regulated transmission network is set by the Australian Energy Regulator (AER). Each year we publish the regulated transmission service prices for directly connected customers, in accordance with the National Electricity Rules (NER).

These prices, quoted in Australian dollars, consist of the following components:

  • Prescribed Connection charge
  • Prescribed TUOS (Locational) charge
  • Prescribed TUOS (Non-Locational) charge, and
  • Common Transmission Service charge.

Inter-regional Transmission Use of System Charges

The Australian Energy Market Commission published its Final Determination and Rule to implement inter-regional transmission charging arrangements in February 2013. Consistent with these amendments to the Rules1, the AER’s Pricing Methodology Guidelines2 and Powerlink’s Pricing Methodology3, Powerlink is required to publish the modified load export charge (MLEC) payable for the following financial year for use of the Queensland transmission network by adjacent regions by 15 February each year.

Powerlink has calculated the MLEC amount payable by TransGrid to Powerlink as follows:
