MAY 1ST BATTERY REBATE CHANGES - EVERYTHING YOU NEED TO KNOW

So far, the federal battery subsidy has been wildly successful in bringing affordability to the table when it comes to investing in energy storage. But with upcoming changes in how much customers can save on their installation, many are anxious about missing out on this savings opportunity.

What’s changing about the Cheaper Home Batteries Program? To put simply, the upcoming changes to the Australian battery subsidy are going to reduce the amount you can save on your battery investment.

Firstly, the STC factor will be adjusted to help incentivise more realistic battery sizes for more Australians with STC factors ranging from 100% for 0-14kWh, 60% for 14-28kWh, and 15% for 28-50kWh. (more on this later) 

Instead of yearly deductions in STC value, the changes will instead bring the Cheaper Home Batteries program to drop every 6-months. This is designed to better fall in line with the deductions in battery costs over time and help give more Australians access to battery storage.

MORE DELAYS INCOMING FOR BATTERY STORAGE INSTALLATIONS: WHY?

On the 5^th of February, the Federal battery rebate regulatory changes were approved and will come into effect on May 1st, 2026.

Since the release of the Australian federal solar battery subsidy (the Cheaper Home Batteries program), there has been constantly increasing demand from Australians wanting to install batteries for their homes and maximise their savings and the incentive.

Towards the end of last year going into 2026, high demand was accompanied by supply issues in various battery brands and models which caused significant worldwide delays. Since then, supply of batteries has increased again which has enabled a massive uptake of battery storage units all over Australia.

However, as the rebate alteration deadline fast-approaches, the industry faces another issue. With such a strong uptake of battery demand, local battery installers are most likely to struggle to keep up and fit everyone in before the May cut off.

WHAT'S THE RUSH? GETTING IN BEFORE MAY 1

Assisted by clever, high-urgency marketing and a low awareness of what’s actually changing about the scheme, customers who want battery storage are now scrambling to get in before rebates drop in price.

Even though most think it will be a dramatic reduction in value, it may not be as much as you think initially. Because of the urgency, installers all over the Newcastle and Hunter region have booked out their calendars to and past May.

How much is the federal battery rebate in 2026? If you compare the same 20kWh battery both installed now and after, you'd be able to get $5,145 off now, but you'd also be able to get $4,165 after May 1. That's a difference of $980.

How much can you save on Tesla Powerwall 3? Using Tesla Powerwall 3 as an example, claiming the federal battery subsidy from January to April will give you a $3,955 discount, and if it’s post-May 1, a $3,185 discount. Whilst the $770 difference could be worth it for some, getting your battery installation after May still provides some valuable discounts of energy storage which would stay the same until the end of December.
This means that not everything is lost if you run out of time before May 1^st hits, where you will only lose a portion of the savings.

WHY IS THE CHEAPER HOME BATTERIES PROGRAM CHANGING?

This means that the higher energy capacities won’t earn as much as the lower end, so the higher you go, the less your discount accumulates.

RED FLAGS: WHAT SHOULD YOU LOOK OUT FOR?

When looking into finding the right battery for you and your household, it can be tempting to just go with any battery installer that says they can do it; but this can be risky.

Here are a few red flags to watch for throughout the federal rebate changes:

• Promising the pre-May discount when the installation is in or after May: Some installers may do this to secure work early when the customer is shopping around. However, they will either ask you for money to cover the differences or have to cover it themselves.
• Choosing an Installer who is not SAA-Accredited: Only SAA-accredited battery installers can provide installations that are eligible for the subsidy.
• Inflating Installation Costs: Some questionable installers may hike their prices so they can absorb more, if not all the rebate value.
• Non CEC-approved battery: The federal battery subsidy is only eligible for CEC-approved energy storage units.
