What it is
A discount applied at the time of purchase, not a separate claim
The Cheaper Home Batteries Program is a federal discount on the upfront cost of an eligible battery system (5-100 kWh usable capacity). Your installer applies it directly to your quote — you don't claim it separately afterwards.
Worked example
10 kWh battery, Sydney (Zone 3)
At the current Zone 3 rate of approximately $252 per usable kWh, a 10 kWh battery (under the 14 kWh full-rate cap) works out to roughly $2,520 off the upfront cost — commonly summarised as around a 30% discount on typical system pricing.
This is an illustration of how the rate applies to one size, not a product this business sells at exactly that size or a quote.
How the rate tapers
The rate steps down as the battery gets bigger
| Battery size | Rate |
|---|---|
| 0 – 14 kWh | Full rate (100%) |
| 14 – 28 kWh | 60% of the full rate |
| 28 – 50 kWh | 15% of the full rate |
The per-kWh rate itself also steps down roughly every 6 months until the scheme ends in 2030 — the next change is expected 1 January 2027.
Good to know
- Eligible battery size range: 5-100 kWh usable capacity.
- Applied by your installer at time of purchase — not something you claim afterwards.
- The exact current rate, eligible battery list and taper depend on your installation date.
