Background to previous rule changes
Rule change March 2014
In late 2013 and early 2014, AEMO consulted on the following minor amendments to the Settlements Residue Auction Rules:
- Including the method for calculating auction expense fees, and updating the formula to reflect that these are calculated over three years.
- Describing the process AEMO uses to reconcile auction expense fees.
- Allowing auction dates to be changed either earlier or later.
- Removing the requirement to publish several notifications on NEMNET.
The Settlement Residue Committee approved the changes to the Settlements Residue Auction Rules in March 2014, and the amended Auction Rules were published on 12 March 2014.
Rule change May 2010
The Australian Energy Market Commission (AEMC) published its final report of the Congestion Management Review on 16 June 2008. The report recommended changing the design of Settlements Residue Auctions (SRA), so auction units would be available up to three years in advance.
During late 2009, AEMO undertook a full consultation on amendments to the SRA Auction Rules, to facilitate auctioning of units up to three years in advance. The amended Rules would be due to come into force on 1 May 2010 in time for the June 2010 auction, where for the first time units would auctioned three years in advance. In addition, AEMO introduced a number of miscellaneous amendments to reflect current auction practices.
The miscellaneous changes included:
- Removing the concept of concurrent auctions, which was no longer required with inter-temporal linking.
- Removing the option for accelerated auctions, as this was no longer considered necessary.
- Correcting a number of Rule references.
- Removing the remaining references to Snowy interconnectors.
The Settlement Residue Committee approved the changes to the Settlements Residue Auction Rules in December 2009, noting the Rules were due to come into force on 1 May 2010.
