NT Home and Business Battery Scheme finished its funding
The Territory scheme that funded home and business batteries has reached its $6 million cap and is closed to new grants. Since 1 December 2024 the scheme paid $400 for every kWh of usable battery capacity, capped at $12,000. The NT Government scheme page confirms that only installs holding a formal grant notification are still covered.
So there is no Territory money to stack onto a new battery today. Your discount comes only from the federal scheme, which makes your install date matter a lot.
How much does the federal discount give you in the Territory?
The federal discount shaves roughly 30% off a battery, and it is identical across all states. It works through certificates, credits your battery generates depending on its size. Each certificate is worth up to $40 via the Clean Energy Regulator's clearing house.
Every 6 months the certificate count shrinks, so waiting means the same battery earns less.
Here is what the discount is worth at different battery sizes. A 10 kWh battery earns $2,720 if it is in by the end of 2026, then $2,280 in the first half of 2027 and $2,080 after July 2027. A 13.5 kWh battery gets $3,640, $3,040 and $2,800 across those same periods. For a 20 kWh battery the figures are $4,760, $4,000 and $3,640, and a 30 kWh battery earns $6,160, $5,160 and $4,720.
Any battery's first 14 kWh earns the full discount. Capacity above that earns less, and anything past 50 kWh earns nothing. Seeing a few real quotes side by side is the easiest way to pick the size that suits your home and your budget, so send the short form and let installers do the sums for you.
Will your battery qualify?
To be eligible, the battery has to follow a few rules from the Clean Energy Regulator:
- It goes in alongside solar panels, either new or ones you already have, on or after 1 July 2025.
- Its size falls between 5 and 100 kWh, and just 1 battery per home can earn certificates.
- It appears on the Clean Energy Council approved list, the register of battery models accepted under the scheme.
- If connected to the electricity grid, it must be capable of joining a virtual power plant — a network of household batteries an energy retailer can tap when demand spikes. You do not have to take part.
- It is fitted by an installer who holds Solar Accreditation Australia accreditation plus a battery endorsement, proof they are qualified to fit batteries.
How the discount reaches your quote
There is no government application for this one. Instead you assign your certificate rights to the installer, who deducts their value from your quote and handles the claiming and selling. All discount amounts assume certificates sell for $40 each, but market prices range from about $37 to $40, so compare the final installed prices.
Common questions
How much is a 10 kWh battery in the Territory after the rebate?
According to CHOICE, a 10 kWh battery runs $7,000 to $11,000 installed once the federal discount is applied. A 20 kWh battery lands between $14,000 and $19,000.
Is the federal battery rebate closing soon?
No. The scheme runs until 31 December 2030, though it keeps getting smaller. In late 2030 the discount on a 10 kWh battery falls to just $840.
Is there a separate rebate for new solar panels in Darwin?
Yes. A 6.6 kW set of panels on a Darwin roof earns about $2,000 if fitted in 2026, dropping to about $1,600 in 2027, and that comes off on top of the battery discount. Both step down in January 2027, so having panels and battery fitted together in 2026 gets the larger amount for each.
