Unfortunately it is only happening quite slowly in Australia despite a successful trial in South Australia some years ago with Nissan Leafs leading to the first commercial application last year.

Elon may have to be dragged to the table with legislation if he doesn't act soon because the opportunity to assist our grid is way too important to ignore.
