South Australia’s Home Battery Scheme

The South Australian Government is delivering on its commitment to provide more affordable, reliable, secure energy for all South Australians.

From October this year, 40,000 South Australian households will have access to $100 million in State Government subsidies and $100 million in loans to pay for the installation of home battery systems.

The subsidy will be available to all South Australians, however Energy Concession Holders will be able to access a higher subsidy, ensuring low-income households are supported to access the Scheme.

While the subsidy will be applied to the battery only, households will be able to apply for finance made available through the Commonwealth Government’s Clean Energy Finance Corporation to purchase new or additional solar panels as well as the battery system.

The subsidy will be scaled in line with the size of the home battery system being installed, calculated on the kilowatt hour capacity of the battery.

Home Battery Scheme subsidy levels


Energy concession holder $600.00 per kilowatt hour (kWh)
All other households $500.00 per kilowatt hour (kWh)

While the subsidy will vary depending on the size of the battery, the subsidy will be capped at a maximum of $6,000 per battery installed.

The subsidy levels and cap are expected to reduce over time as competition in the market increases and the cost of home battery systems goes down.

A set of minimum technical requirements for battery systems has been developed to ensure the batteries are safe, reliable and capable of being recruited into a virtual power plant.

While households will be able to choose whether or not their home battery system operates as part of a virtual power plant, the ability to aggregate home battery systems - either now or at a future point in time - creates opportunities to address network issues and smooth loads by balancing out peak power demands.

The Scheme will directly reduce electricity costs for the 40,000 households that purchase a home battery system. In addition, the installation of these systems will reduce demand on the network (especially at peak periods) and in turn lower prices for all South Australians.

A dedicated website will be available in October to assist homeowners consider their suitability for a home battery system, choose between approved products and system providers, access the subsidy and apply for finance, if required.

Industry participation

To supply and install eligible home battery systems under the Scheme, industry providers will be required to first qualify as a System Provider.

As part of the qualification process, installers and suppliers of home battery storage systems will be required to specify the extent to which their products and services contribute to the South Australian economy.

In assessing applications, priority will be given to System Providers that commit to installing approved battery systems that are manufactured or assembled in South Australia.

These Providers will be afforded a nine-week priority period when the Scheme launches in October.

Register your business

Businesses interested in becoming System Providers can register their contact details below, to be notified when the accreditation process is announced.

A call for businesses who have registered their interest in applying to become qualified System Providers is expected to occur later this month.

Glossary of terms

Home battery storage system
A home battery storage system includes a battery and an inverter, paired with existing or new rooftop solar panels.

System Provider
System Providers are product providers and system installers. They may include manufacturers, distributors, suppliers, retailers and installers who are qualified to supply and install home battery storage systems.

Virtual power plant (VPP)
A virtual power plant is created by a network of home solar panels and battery systems all working together to generate, store and feed energy back into the grid.

Energy from the rooftop solar panels and battery systems installed as a part of this virtual power plant will provide electricity for the houses on which they are installed. Any excess energy generated by the system will be automatically dispatched to the grid. This dispatched energy will be centrally controlled to meet the needs of the grid, providing additional energy to the rest of the state, when it is required.
