Infigen to supply Tesla, page-18

OkAY Andrix, so you tell me how the Lake Bonney Big Battery feeding into the SA grid can power Tesla supercharging stations up the east coast of Victoria, New South Wales and south Queensland.
As I think you could be stumped for an answer, here is what I suggest might have happened. Infigen PR tells the Minister BESS will supply enough energy to power all the Tesla recharging stations and one of the Minister's staffers translates this as a contract for Infigen to supply the supercharging stations. Does that sound plausible or have you another explanation (maybe the Lake Bonney power flying through the atmosphere?)
PS I did read the other posts, none of which explained this energy miracle.
