AEMO published the Final Determination and MASS on 1 June 2020. The files are located in the ‘Consultation Documents’ section below. Note that the revised MASS will take effect from 1 July 2020.

AEMO wishes to thank participants for their involvement in the consultation, and for their time and effort spent in making submissions.

Causer Pays

As flagged in the consultation notice, the proposed changes to the Causer Pays procedure were contingent on the AEMC making a rule on ERC0263 “Removal of disincentives to primary frequency response”. The AEMC has deferred a draft determination on this rule to 24 September 2020. Therefore AEMO is halting further consideration of the matters flagged under this Causer Pays consultation until a later date to be advised. 

The dates in this revised timetable below apply only to the MASS consultation.
