The Tesla’s big battery in South Australia has already taken a 55 per cent share in the state’s frequency and ancillary services market, and lowered prices in that market by 90 per cent, new data has shown.

And the 100MW battery has achieved over 55 per cent of the FCAS revenues in South Australia. So it’s 2 per cent of the capacity in South Australia achieving 55 per cent of the revenues in South Australia.

…

Various estimates have put the cost savings to consumers from the FCAS market alone at around $35 million, just in the first four months of its operation.

That’s a pretty good bang for the buck for the estimated $50 million investment by the South Australia government. South Australia is the only state that has experienced a decline in FCAS prices over the past few months.
