What it does
The federal battery discount — commonly called the Cheaper Home Batteries program — extends the same certificate mechanism used for solar to battery storage. You install an eligible battery, certificates are created against its capacity, and the value is deducted from your price at the point of sale.
Like the solar scheme, it is not a payment you claim afterwards. It arrives as a lower invoice.
The capacity cap
The discount is calculated on usable battery capacity, and it is capped. Beyond the cap, additional capacity is not subsidised — you can install a larger battery, you just do not get a larger discount for the part above the limit.
Usable capacity is the figure that matters, and it is lower than the nameplate figure printed on the box. A battery advertised at a given size will have a usable capacity somewhat below it, because running lithium cells to absolute empty shortens their life. Make sure your quote states which figure it is using.
Confirm the current cap and per-kWh rate These numbers are set by regulation and step down annually. Check the Clean Energy Regulator's current figures before quoting them to a customer.
The VPP-capable requirement
To qualify, the battery must be capable of being connected to a virtual power plant — a scheme where a retailer can discharge your battery into the grid at peak demand in exchange for payments.
Capable is not the same as enrolled. You are not obliged to join a VPP to receive the discount. If a salesperson tells you a VPP contract is compulsory to get the rebate, that is wrong, and it is worth asking what else they have told you.
VPPs can be worth joining. They can also mean less control over your own stored energy and a minimum contract term. Treat it as a separate decision made on its own merits.
It also steps down each year
Like the solar scheme, the battery discount reduces annually on a published schedule through to 2030. The same logic applies: waiting reduces what you receive.
What makes a battery eligible
- Listed on the Clean Energy Council approved battery list.
- Installed by an accredited installer to AS/NZS 5139.
- Within the scheme's capacity range.
- VPP-capable.
- Connected to a compliant, approved grid connection.
How this changes the maths
Before this scheme, a home battery in Victoria generally did not pay for itself within its warranty period on electricity savings alone. Taking roughly a third off the installed cost changes that calculation materially, particularly for households with high evening consumption and a feed-in tariff worth very little.
It does not make a battery right for everyone. If you are out all day, use very little power in the evening, and have no interest in blackout protection, storage may still not be your best spend. We will tell you that rather than sell you one.
