Yesterday (Friday 13th June 2025), amongst the discussions about recent market events during the early winter cold snap, the AEMO published both of the following documents:
| Draft Report | Draft of the Proposed ‘Security Enablement Procedures’ |
|---|---|
|
There’s a 34-page Draft Report on the Security Enablement Procedures available here:
From within this document, Figure 1 (on p8/34) was helpful, and so I’ve copied in here for readers:

There’s a draft of the proposed ‘Security Enablement Procedures’ (SO_OP_3720) available here:
This draft contains, on p6/30, the following Figure 1 that might be useful to some readers, so I’ve copied in:

But readers should read both documents above themselves!
Noted by the AEMO
We’re on the AEMO distribution list for emails relating to these reforms, and I thought it would be useful to copy in here some of what was in the email we received on Friday afternoon:
‘Today, AEMO published the draft report of the Security Enablement Procedure (Procedure) in accordance with new NER 4.4A.6(a) introduced by the AEMC’s Improving Security Frameworks (ISF) rule change.
Commencing on 2 December 2025, the rule introduces a new capability for AEMO to enable (or ‘schedule’) security services with a whole-of-NEM perspective and this draft report follows the Consultation paper, published 7 April 2025.
With this draft report, AEMO has considered stakeholder submissions and provided updated content in the draft Procedure, which includes a methodology for determining system security requirements along with processes to enable system security services to meet these requirements. In addition, guidance has been provided on minimum and recommended requirements for system security services agreements entered into by TNSPs.
<< SOME DATES BELOW>>
In addition, AEMO is consulting on minor administrative and consequential amendments to:
(a) SO_OP_3708 Non-market Ancillary Services (including the Guide to Ancillary Services in the NEM)
(b) SO_OP_3704 Pre-Dispatch Procedure
(c) Spot market operations timetable
(d) SO_OP_3718 Outage Assessment, and
(e) SO_OP_3715 Power System Security Guidelines
(f) Schedule of Constraint Violation Penalty Factors.’
