Tesla "big battery" in Australia is becoming a bigger nightmare for fossil fuel power generators

Tesla's "big battery" utility-scale Powerpack system at the Hornsdale Power Reserve [(HPR)] in South Australia has yielded more than doubled[sic] the savings to consumers in 2019 than the year prior as it dominates fossil fuel generators on quicker demand response for the grid.

Hornsdale Power Reserve saved consumers AUD116 million ($75.78 million) in 2019, a big jump from AUD40 million ($26.14 million) savings in 2018.

The Hornsdale Power Reserve, owned and operated by French renewable energy producer Neoen, is home to the largest lithium-ion battery energy storage system in the world with a 100 MW/129 MWh. Tesla Powerpack [that] has been playing a significant role in grid stability since its installation in 2017, a function previously dominated by fossil fuel generators that bring energy prices high during system faults [or] planned maintenance.

"Hornsdale has just been the best asset for the state, and for us as well, it's a real success story," head of development at Neoen Australia Garth Heron said in an interview with RenewEconomy. We have shown that these kinds of systems can work. It saves consumers a lot of money, and it's something we should be rolling out right across the market."

[...]The HPR also announced plans to expand its capacity by 50%, boosting it by 50MW/64.5MWh. The project is expected to be completed in the first half of 2020 and will provide stabilizing inertia services critical to the shift to renewable energy in the region, and help push Australia closer to its goal of being net 100% renewable by 2030.
