Karratha Tender Outcome, page-4

West Australia Alternative Energy doesn't have much battery references (they're mostly doing solar installations), but they have trial deployment with Tesla batteries in Mandurah (Meadow Springs).

So quite likely this will be Tesla Powerpack batteries, with some wasted electricity for A/C system to keep them cool in Karratha summer, so Teslas don't go Geelong.

Their accepted proposal has budgeted cost of $2.15M for batteries, so there will be battery installation, not just solar.
