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, in July 2016, the Government awarded ZEN Energy with a $1 million tender to install lithium-ion batteries at three Government-owned sites around the city. The sites offer the greatest potential for high demonstration value, low technical risks and opportunities to achieve energy cost savings.
