Indicators of the market impact of transmission congestion - Final Decision & Report for 2003-04

The Australian Energy Regulator (AER) has released its final decision - Indicators of the market impact of transmission congestion and first report for 2003-04 of the same title. The AER's decision is to publish indicators on the market impact of transmission congestion.

This decision results from significant work: initially commenced by the Australian Competition and Consumer Commission (ACCC) and then progressed by the AER. In undertaking this work the AER has been assisted by input from many stakeholders. The primary objective of this decision is to publish information to improve understanding about transmission congestion.

Data on each of the indicators relating to 2003-04 has been released in conjunction with this decision. Results for 2004-05 and 2005-06 will be released in the third quarter of 2006.

The AER cautions against drawing conclusions from a single year's data. The AER considers that as more data is published and stakeholders can provide feedback, reliable conclusions may be reached.
