Ann: Q2 FY22 Investor Update Webinar Presentation, page-12

I'm unsure how they plan to add 3-4 more batteries to the portfolio in the next five years though...BBP was first announced in Aug '20, and 18 months later we're not at FID. It'll likely be 2.5 years between first announcement and operation of the BBP. If that is the general time frame for such projects, since we haven't had any more battery announcements, the next battery won't be operational until around when K2H is completed at the end of 2024.
