Submissions closing tomorrow (Wed 13th Aug 2025) to AEMO consultation on ‘Primary Frequency Response Test Guidelines for Semi-Scheduled Plant’

Posted by Paul McArdleTuesday 12th August 2025  3:55 PM   Topic: Obligations of Semi-Scheduled Units, Primary Frequency Response (PFR)

As noted 7 days ago (Tue 5th July), I’ve just returned from over a month away (and disconnected from the NEM), and have been striving to catch up.

One of the things I think everyone in our team missed – and you might have as well – is that the AEMO’s been working through Primary Frequency Response (PFR) Test Guidelines for Semi-Scheduled Plant:

1)  They have a sub-site here dedicated to this;

2)  And released the following two drafts in early July 2025

 

The draft Report Consultation Questions

There’s a short (9-page) draft report here:

2025-07-02-AEMO-PFR-TestGuidelines-SemiSched-draftReport

There’s also the draft (16-page) Guidelines document here:

2025-07-02-AEMO-PFR-TestGuidelines-SemiSched-draft

 

3)  With submissions closing tomorrow … Wednesday 13th August 2025.

 

So now I know, and you know as well …

    Hi Paul, you have probably got this a hundred times already, but in case it was missed; in the headline you have Fri 13th instead of Wed 13th. Spooky.
