July 25 Energy Storage Update:
How Long Could Australia’s $2.3B Battery Rebate Last?
​
Following our July 19 post about the Federal Government’s $2.3 billion home battery rebate program, interest has surged and industry chatter is everywhere. Here’s the latest snapshot based on this week’s installation and STC submission data.
​
📊 STC Activity & Installation Volumes
-
July 19: 1.44 million STCs lodged, covering 8,918 battery installations.
-
Some asked whether July could hit 3 million STCs — early signs now confirm it’s likely.
-
By July 25: Submissions have climbed to 2.248 million STCs across 13,877 systems. With 4 days to go, the 3 million milestone is well within reach.
​
âš¡ Average System Sizes & Supply Constraints
-
Current average: 162 STCs per install → roughly 20kWh systems.
-
Limiting factors are battery stock levels and inverter compatibility, not consumer demand.
-
August outlook: As new shipments arrive, average installs are expected to rise to 25kWh+.
​
📅 Projected Life of the $2.3B Scheme
-
If 25kWh remains the norm, the rebate could cover around 236,000 systems.
-
Manufacturer forecasts point to 5M+ STCs claimed in August–September.
-
At the fixed $40/STC rate and a total pool of 57.5 million STCs, funding could be fully used by April 2026 — possibly sooner if demand accelerates.
​
Bottom line: This isn’t a permanent program. The clock is ticking.
​
🧰 Installer Capacity
-
Australia currently has enough licensed battery installers to meet demand — supply, not labour, is the pinch point.
​
🔄 Will Prices Just Keep Dropping?
While solar panel prices declined over years, the battery rebate works differently:
​
Solar STC Scheme
-
Ongoing program.
-
STCs are traded by electricity retailers under carbon offset rules.
-
No fixed expiry.
​
Battery Rebate Scheme
-
Direct federal funding — $2.3B capped budget.
-
When the pool is spent, the program ends — no extensions.
​
✅ Key Insights
-
Generous rebates are available now — but limited.
-
July alone is set to hit 3M STCs.
-
Current trends suggest the scheme could end by early 2026 — or sooner with strong uptake.
-
Installing larger systems (30–50kWh) now maximises your rebate before supply balances and funding runs out.
​
If you’ve been holding off, the numbers make it clear
- act now. Once the rebate fund is exhausted, it’s gone for good.
