The Commission has determined to make a rule in regard to the timing requirements for STTM participants to submit market schedule variation (MSV) transactions to the STTM market operator, for inclusion in the market settlement process.
The effect of this rule is to remove the provision relating to the MSV timing requirements from the National Gas Rules (NGR), with the intention that the Australian Energy Market Operator (AEMO), the STTM market operator, will insert an equivalent provision into the STTM procedures.
This rule will transfer responsibility for consideration of any future changes to this provision to the STTM market operator. The framework for managing changes to STTM procedures is set out in the NGR. The main provision, establishing the MSV mechanism and the parameters within it may they operate in the STTM, is to be retained in the NGR.
