Amongst the general ‘busyness of business’ I do try to keep an eye on what’s happening in the mainstream media*, related to the broader energy sector.

* it does seem that there’s now seldom an ‘Energy News free day’ these days.

So I had noticed that Akaysha Energy had put itself on the market recently

… for instance, this was noted in the AFR Street Talk on Monday 1st June 2026 via ‘BlackRock’s Akaysha Energy forecasts $600m earnings as data room opens’.

Frequent readers will recall:

1)  that we’ve been progressively documenting the long unplanned outage at Waratah BESS here:

(a)  following the ‘Catastrophic Failure’ of 1 of the 3 transformers on site

(b)  as a result of which the 2nd of 3 transformers was also taken offline pre-emptively as a result

… this one was returned to operations in early April 2026 for testing purposes.

2)  You might also have noticed that, last Saturday (30th May 2026) on RenewEconomy, Giles Parkinson noted that ‘Delays at Australia’s most powerful battery led to a more than $90 million cut in payments’.

3)  Readers here might recall that we’ve been using the ‘Notifications’ widget in ez2view to keep us informed with large changes in output at this unit (one of many we watch):

… that alert has been triggering more frequently in recent times, but our focus has been elsewhere, so looking further’s been pushed onto the ‘to be done later’ listing…

However today (Friday 5th June 2026) a couple of our readers prodded us to noticed the News Update ‘Waratah Super Battery now operating at 700MW’ …

1)  a good news story, for a company that’s selling itself.

2)  with the article noting:

‘The full 700MW SIPS service will be provided when High Voltage Transformer 3 (HVT3) is operating later this year and Waratah’s full 850MW / 1,680MWh capacity is online.’

… i.e. so I’m gathering that this is related to the 2nd transformer that’s passed testing (since early April), with the 3rd transformer (the one being replaced) still on the way.

So I’ve invested a short amount of time this evening to have a quick look at what’s visible in ez2view.

Recapping history over the past ~2 years

Whilst the the ‘Bids & Offers’ widget in ez2view is more commonly used to look at a shorter range of data, it can be used to look back over bids (and dispatch) ranging over a longer range of time – such as in this snapshot:

Interesting to note that:

1)  Since the 2nd transformer came back to service (for testing), the units often been charging at greater than it has been discharging;

2)  From an availability point of view:

(a)  Whilst the ‘PASA Avail’ in the bid has been set at +700MW (discharge) and –700MW (charge).

(b)  The Availability (i.e. to which commercial prices are attached) has tended to be seldom over +406MW (discharge) and seldom below –556MW (charge)

  … although that could well be due to SIPS obligations.

Looking forwards ~3 years

Readers here will recall that we often use the ‘Forecast Convergence’ widget in ez2view:

1)  To look forward through the MT PASA DUID Availability data set;

2)  In order to ‘look up a vertical’ in order to see ‘that other dimension of time’.

So here’s a current view of the unit via that lens:

With this view:

1)  In the interpretation of what this shows, remember the AER’s clarification of how obligations (such as SIPS obligations) should be represented:

(a)  In the MT PASA DUID Availability data set;

(b)  As distinct from the PD-ST PASA Data Set, which has only been visible per unit since July 2025.

2)   We can see that the most recent significant change was actually back in early April 2026, when the second transformer was returned to operations in early April 2026 for testing purposes.

Nothing further, at this point.
