Market impact of transmission congestion report 2005-06 (February 2007)

Network service provider performance
Release date: 
1 February 2007


On 13 June 2006, the Australian Energy Regulator released its decision to publish indicators of the impact that transmission networks can have on the rest of the electricity market. The AER has adopted a two stage process for the improvement of the current service standards regime, by moving towards a regime that was directly linked to market outcomes. The first stage of that process is the publication of three annual reports covering the market impacts of transmission congestion for the financial years 2003-04, 2004-05 and 2005-06.

This report is the third annual report in response to that decision. As a second stage, in early 2007, the AER will consult with the market in order to develop a service standards regime based on the understandings gained through these reports.

The aim of this report is to:

  • identify the market impact and causal elements of constraints
  • provide information to participants that will be used as a tool for guiding behavioural decisions, therefore promoting efficient market participant behaviour
  • be used as a tool to develop possible economic incentives
