Final determination made on STTM Deviations and the Settlement Surplus and Shortfall rule change request

20 June 2013

On 20 June 2013, the AEMC published the final rule determination and final rule, which is a more preferable rule, for the STTM Deviations and the Settlement Surplus and Shortfall rule change request.

The final rule largely adopts the changes proposed by the rule change proponent, the Australian Energy Market Operator (AEMO),  subject to some exceptions. This includes creating a set of principles and parameters in the National Gas Rules (NGR) to guide AEMO in the development of deviation pricing through future STTM Procedures changes and consultation processes.

The final rule will commence on 1 May 2014.
