We have decided to amend the Code to ensure that constrained on and constrained off payments made to dispatchable load purchasers align with the intended economic purpose of such payments. The amendment provides for the situation when a dispatch bid for a dispatch-capable load station is revised during the 30 minutes prior to the start of the relevant trading period. The amendment will promote the efficiency limb of our statutory objective by ensuring that constrained on and constrained off payments are made for the intended reasons.

We have published a paper outlining the reasons for this decision and a summary of the submissions received. We will publish the Gazette notice shortly and the amendment will come into force on 1 December 2015.
