The AEMC has published a rule change proposal by the Australian Energy Market Operator that relates to the determination of deviation payments and charges in the Short Term Trading Market (STTM). The AEMC has also published a consultation paper to facilitate stakeholder feedback on the proposed rule change. Submissions are requested by 20 December 2012.

In addition the AEMC has given notice that it has extended the period of time for making a draft determination and if needed a draft rule under s. 317 of the National Gas Law. This extension of time is required due to the complex issues raised by the rule change proposal, including issues related to what matters should be contained in the National Gas Rules and what should be in the Procedures. The draft determination will be published by 28 March 2013.
