Interview with SK, not sure when this was done (pre investment decision maybe) but it's recent article and some hints at Rockhampton battery supplier.

Simon Kidston: We've partnered with a global Tier 1 battery supplier. A well-known US firm will be supplying the battery systems and energy trading systems. We're putting in place the pre-connection process at the moment. Concurrent with that, we're working on the project financing. The project has been sized as 50 megawatts or 75 megawatt hours, which means the 50 megawatts can generate for 1.5 hours before the battery's been discharged.And interestingly, from a revenue perspective, it has two forms of revenue. One is energy arbitrage, which is the delta between peak and off peak energy prices. That's the first revenue stream. The second revenue stream is what they call auxiliary services, or FCAS services, which has proven to be a very, very profitable revenue stream for other battery developments that are operating in the Australian market. So we'll be targeting both revenue streams. The beauty of battery projects is they can be built very quickly and we would expect that project to be operating by early 2022.
