There are a range of methods and technologies to store energy. This can include batteries, flywheels, compressed air, thermal and pumped hydro. Learn more about energy storage.
Coupling energy storage with renewable energy provides stability services and emergency back-up power if a shortfall in energy is predicted. This helps overcome intermittent power generation (i.e. solar power is only generated when the sun shines), and can provide energy when it is needed.
South Australia has the world’s largest lithium-ion battery. Following an Expression of Interest process, the South Australian Government announced Tesla in conjunction with Neoen to build a lithium-ion battery in Jamestown. The battery delivers power to the National Electricity Market, providing system security services.
The Government of South Australia supports energy storage projects through programs and funding. For instance, the $50 million Grid Scale Storage Fund, the $100 million Home Battery Scheme and South Australia’s Virtual Power plant are key components of the South Australian Government’s energy policy.
