A collation of articles written on WattClarity pertaining to the design, implementation and operation of various System Integrity Protection Systems (SIPS) in relation to Network Support.
A short post to note that the Waratah Super Battery tested its full SIPS capacity of 700MW for around two hours yesterday morning — the first time it was able to do this since last October's transformer failure.
Another* of our keen readers (and ez2view users) flagged some more machinations to us with respect to Waratah BESS that occurred yesterday (Monday 23rd March 2026).
One of our keen readers and ez2view users has pointed this out to us, so we’re sharing this with you now that the Victorian Big Battery was operated for SIPS on Friday afternoon/evening 9th January 2026 (appears to have been on 3 occasions).
On Friday afternoon we asked the question ‘What’s up with Waratah BESS (unplanned outage till 3rd May 2026)?’. It was great to see (on Monday evening) Angela MacDonald-Smith answer some of these questions in the AFR, and then a media update from Akaysha Energy.
Relevant to today's questions, we belatedly note now that it was back on Friday 29th August 2025 that the AER published its PASA Compliance Bulletin and Checklist.
The Waratah Super Battery System Integrity Protection Scheme (SIPS) was enabled by TransGrid at last Friday 1st August 2025. This prompts this look back on operations thus far.
In this article we circle back to Tuesday 13th February 2024 to tick off a few more of the long list of questions about the 'Major Power System Event' - in this article with respect to operations of the Victoria Big Battery.
Prompted by the other article today, I've taken a look at published information about the required operations of the Victoria Big Battery (VBB) under the System Integrity Protection System (SIPS).
Six observations from a chart summarising how capacity, availability and volumes enabled have changed over the early phase of the very fast FCAs markets, since commencement on October 9, 2023.
