Change Start Date & Time: 30/05/2016 10:00:00 AEST
Change End Date & Time: 30/05/2016 12:00:00 AEST
Change Description:
This change is to support the new generator ramp rate rules starting on 1st July 2016.
As part of this change AEMO will publish data informing Participants of their Minimum Ramp Rates including Generator DUID and individual unit max capacities. (Refer to the AEMO Tech Spec 931 issued 18th March 2016 for more information.)
The new minimum Ramp Rates will become effective and be used in validation from trading day 08/06/16 in Pre-Production and from 01/07/16 in Production.
