The WA battery rebate (and loan)

In May 2026, Synergy finally removed this clause in their contract.


As a result we feel that the WA rebate, which we refused to offer up until now, is more acceptable.
We might start to offer it once some other issues are resolved.
These partly relate to slow payment by the loan administrator, Plenti.

The Federal battery subsidy.
The $2.3 billion allocated for the Cheaper Home Batteries Scheme will run out by May/June 2026.
It was meant to expire in 2030 but people have been installing much larger batteries than expected.

The Government has announced (13th December 2025) that they are putting another $5 billion into the scheme.
But they are radically changing how the subsidy will operate.
It's quite a complicated formula, so to make things easier, I've created the calculator below.

You can select from a range of popular batteries, or just enter your own value.
(The subsidy is paid on the 'usable energy' not the rated energy and sometimes these are 5-10% different).
