South Australia started their switch to renewables long before anyone else . Well before the rest of the east coast .

With what is relatively old technology .

The South Australians showed the world what is possible for a state sized grid particularly for grid batteries . Remember when your mate ScoMuppet called it the big banana ? The same idiot that claimed evs would wreck the weekend ?

South Australia have set the standard at 75% of annual power generation hence the reference . They are the leader in the space .

The Hornsdale battery was the first of its kind in the world . Now Tesla can't build them fast enough . Tesla's grid battery business is expected to surpass that of their ev business .

Tesla battery business is worth nearly $200 billion, more than any Australian company except BHP
