What is the Cheaper Home Batteries Program?
The federal Cheaper Home Batteries program is a $7.2 billion initiative providing approximately $258 per kWh (about 30% off) on the first 14 kWh of an eligible battery system. It is available to all Australian homeowners with solar when using a SAA-accredited installer.
Since 1 May 2026, tiered rates apply: the first 14 kWh receives 100% of the STC factor, 14 to 28 kWh receives 60%, and 28 to 50 kWh receives 15%. The STC factor steps down again on 1 January 2027 and every six months until the program closes in 2030, so installing sooner secures a larger discount.
- Point-of-sale discount applied directly to your quote.
- All SAA-approved batteries are eligible (Tesla, BYD, Sungrow and others).
- The program runs through 2030 with $7.2B in funding.

No. The NT does not currently offer a territory-level battery rebate or subsidy. However, the federal Cheaper Home Batteries program provides a significant discount and is available to all NT homeowners with solar.
