With large subsidies on the cost of a battery and low interest finance available if needed, there has never been a better time to invest in solar and a battery for your home.

South Australia’s Home Battery Scheme means cleaner, more affordable, reliable power for every household that purchases a system. In addition, the installation of these systems will reduce demand on the network (especially during peak periods) and in turn, lower energy prices for all South Australians.

$2,000 Subsidy

The Home Battery Scheme is currently offering $2,000 off a new Home Battery, which is available to qualifying South Australian households. The Home Battery Scheme has been made possible by the $100 million in state Government Subsidies allocated by the South Australian Government.As the Home Battery Scheme only subsidises the purchases of eligible Home Batteries, the Clean Energy Finance Corporation has matched the $100 million in State Government Subsidies to make low-interest finance options available for both Solar and Battery purchases, which is facilitated through Plenti and CommBank Green Loan.

The intent of a home battery system is to reduce one’s reliance on the grid, to get more usage from your solar system, access to blackout power and to reduce energy bills.

How is the Home Battery Scheme Subsidy calculated?

The subsidy is available to all South Australians, and calculated on the kilowatt hour capacity of the battery purchased. Furthermore, Energy Concession Holders are eligible for a higher subsidy, ensuring low-income households are supported to access the Scheme.

Energy concession holder $250 per kWh
All other households $150 per kWh
Maximum subsidy per battery installation $2,000

The subsidy will continue to be phased down as uptake of the Scheme increases.

What is a home battery system?

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

The system works by storing excess generation from your solar panels ready for use at other times – such as during cloudy periods or when the sun goes down. By storing and using more of the energy generated by your solar system, your household can draw less energy from the grid, saving you money on your energy bill. This means lower electricity costs for the households who purchase a system.

Home Battery Scheme FAQ’s

Dont Own Home 0 01

Am I eligible for a Home Battery Subsidy?

The Home Battery Scheme is accessible to all SA households, who have or are willing to get sufficient solar, that are connected to the SA Power Network’s grid?

How much will a Home Battery save me?

Home Batteries store energy produced by roof top solar panels to use at a later stage, such as in the evenings or early mornings when solar is not as efficient. A Home Battery also allow you to use grid energy when tariffs are low and switch to battery storage when energy rates are high, which reduces electricity usage at peak hours, therefore reducing energy bills. On average, batteries can contribute 30% of a household’s energy usage.

Is a Home Battery Affordable?

A Quality Home Battery is expensive, however, the Home Battery Scheme and CEFC have made efforts to assist with reducing the costs of a home battery to a home owner. These efforts include the introduction of the Home Battery Subsidy of up to $2,000 off a new Home Battery and low-finance options from CEFC, and others. In addition to this, eligible Home Battery owners have the option to join the Virtual Power Plant (VPP) via various providers.

I already have a Solar System. May I add more panels when purchasing a battery?

Yes. As we analyse clients on an individual basis, we do find that clients may require an upgrade/expansion to their solar system to meet their energy requirements. Please keep in mind that the home battery subsidy only applies to the Home Battery and not solar or separate inverters, however the low-interest finance options may be used for the purchase of batteries and / or solar.

May I access the subsidy if I do not own my home?

Yes, However you will need to get owner’s consent and demonstrate the owner’s consent to the Home Battery System Provider before installation. You may not remove the battery from the property in the even that you move to another property.

May I live Off-Grid with a Subsidised Battery?

No. The Home Battery Scheme was developed so that home battery systems can become affordable and can also feed the grid to form part of the Virtual Power Plant. Therefore, subsidised home battery systems need to remain connected to the SA Power Network’s electricity network.

np application 168505 BCD321 01

Can I access the subsidy more than once?

Yes. If you own multiple properties, you can access the Home Battery Scheme’s Subsidy more than once. However, the property must be a residential property and you can only access the battery subsidy once per property. You will be required to provide the National Metering Identifier (NMI) of the property when applying for the Home Battery Scheme subsidy (this can be found on your bill).

Will I have to change my energy retailer?

Not necessarily. Many System Providers will be offering battery systems which are not tied to a program operated by a particular energy retailer. However, it is anticipated that energy retailers who offer eligible home batteries as part of a virtual power plant program may apply to become qualified System Providers. If you choose to purchase a home battery system that will be part of a virtual power plant, a condition of purchasing the home battery system may be that the System Provider becomes your energy retailer.

I’ve signed up to a virtual power plant, am I eligible for the subsidy?

Yes, if the operator of the virtual power plant has been approved as a qualified System Provider and the home battery system meets the Equipment Eligibility Criteria of the Scheme, and you will own the battery system. However, the subsidy cannot exceed the amount you pay for the system. You should enquire with the operator of the virtual power plant for more information.

Do I need council approval to install a battery?

If you live in a multi-storey residential flat or apartment building, where a dwelling sits vertically above another dwelling, you may need council approval to install a home battery system. Enquire with your local council as to whether a development approval is required prior to purchasing a home battery system. It is also recommend you seek written approval from your body corporate and/or building manager for the installation prior to agreeing to the purchase of a home battery system.

Can I get the subsidy for a battery installed before the Scheme launched?

Batteries purchased and installed prior to October 29, 2018 will not be eligible for the subsidy.

Home Battery Scheme Subsidy Changes

Since its launch in October 2018, the response to the Home Battery Scheme has been incredibly positive. The Scheme has supported the installation of thousands of home batteries, paved the way for a number of virtual power plants to enter the market, and reduced the average price of a battery system in South Australia.

As a direct result of the Home Battery Scheme and other government-supported programs such as South Australia’s Virtual Power Plant and Batteries for Bushfires, there are now over 26,000 batteries installed or approved for installation at homes in South Australia. According to industry analysts Sunwiz, 29% of all home batteries installed in Australia in 2020 were installed at South Australian homes – leading all states and territories.

The Scheme means cleaner, more affordable, reliable power for every household that purchases a system. The installation of these systems also reduce demand on the network (especially during peak periods) and in turn, lower energy prices for all South Australians.

Following continued uptake of the Scheme, the subsidy levels and cap of the Home Battery Scheme have decreased.
