Australia is building the world's biggest battery — and it's not even the most ambitious storage project the country has underway.
The Victorian Big Battery near Geelong — 300 MW / 450 MWh of Tesla Megapack units — became one of the world's largest battery installations when it came online in 2021. It was overtaken almost immediately by South Australia's Hornsdale Power Reserve expansion. Then came Western Australia's Kwinana Big Battery. Australia is engaged in a continuous competition with itself to build larger and smarter grid storage systems.
But Snowy 2.0 dwarfs them all. The pumped hydro expansion of Australia's Snowy Mountains scheme is the largest energy storage project in the Southern Hemisphere — 2,000 MW of generation capacity connected to 350,000 MWh of storage in the form of two reservoirs linked by 27 kilometers of underground tunnels bored through the Australian Alps. When complete, it will store enough energy to power Sydney for a week.
Australia's storage buildout is driven by a grid undergoing one of the fastest renewable energy transitions in the world. Coal plants are retiring faster than anywhere else on Earth — 7 GW retired in 2023 alone — and the National Electricity Market needs storage at every timescale: seconds for frequency, hours for daily solar cycling, and days for extended low-generation weather events.
No country is learning faster how to integrate massive renewable generation with massive storage. Australia is running the experiment the entire world needs data from.
