Australian Tesla battery owners may lose out on significant revenue opportunities due to the company's restrictions on local third-party interactions. 

The company is imposing a limitation that hinders the ability of the $15,000 Powerwall 2 batteries to adjust power usage during peak periods, which could otherwise generate income by supplying electricity back to the grid.

In the United States, Tesla is required to enable interoperability in many states, but this feature is disabled in Australia. 

Industry experts suggest that Australian authorities should enforce similar mandates to those in the US, adhering to the international standard IEEE1547-2018 Clause 10. 

The Australian Energy Market Operator (AEMO) says coordinated consumer energy resources (CER) storage could be essential for a cost-effective transition to renewable energy. 

AEMO predicts CER storage will grow to 37 gigawatts by 2049-50, making up two-thirds of the national electricity market's storage. Without proper coordination, an additional $4.1 billion investment would be required for grid stability.
