On 28 March 2013, the AEMC published the draft rule determination and draft (more preferable) rule for the gas STTM Deviations and the Settlement Surplus and Shortfall rule change request.

The Commission has proposed to make a more preferable rule that largely adopts the changes proposed by the rule change proponent, the Australian Energy Market Operator (AEMO), in their rule change request. In addition, the draft rule also creates a set of principles and parameters in the National Gas Rules (NGR) to guide AEMO in the development of deviation pricing.

Stakeholders are invited to make submissions in response to the draft rule determination, including the draft rule, by no later than the close of business on Thursday, 9 May 2013.
