But I don't think Horndale has a PPA for its battery output (ignoring the part that is contracted by the SA Govt) - it will only be supplying power when they can get a good price in the market. This may be during the day when there are power shortages (as was the case in SA and VIC earlier this week) but most likely concentrated in the evening peak. I assume it has a PPA for the wind farm itself.

With Kidston, they have both Solar and PHES for stage 2. So they have the choice as to whether they use the solar to "recharge" the PHES during the day, or use cheap baseload power overnight after the evening peak has ended (or a combination of both) and sell some or all of the solar into the market during the day. Then the PHES - do they have a PPA in place for that, or sell on market like Horndale battery? If the NEG ever happens, then retailers will want a contracts for dispatchable power, and the Kidston PHES should qualify there, being able to generate 2GWh of power per day.

Ouch - fries my brain thinking about the options.
