A federal authorities program that provides a 30% subsidy on house batteries has sparked an “off the charts” surge in installations, with greater than 11,500 purposes to the scheme in its first three weeks.
Trade analysts stated the battery growth was paying homage to the surge in rooftop photo voltaic 15 years in the past, and that it was ushering in a second revolution in house electrical energy.
In response to information supplied to Guardian Australia by the Clear Power Regulator (CER), 11,536 batteries have been put in because the authorities’s $2.3bn Cheaper Dwelling Batteries Program opened for connections on 1 July. Greater than 1,000 batteries have been being put in each day.
The managing director of photo voltaic consultancy SunWiz, Warwick Johnston, stated on some days extra battery programs had been registered than stand-alone photo voltaic programs – a primary for Australia.

“Before the scheme was announced, there were about 75,000 battery installations in 2024 compared to 300,000 solar PV systems. So to go from one in six, to one [for] one, shows this [program] has unleashed a wave of interest,” he stated.
The CER information confirmed about 40% of the installations since 1 July have been in New South Wales, 20% in Queensland, 17% in South Australia and 12% in Victoria.
Residents in NSW can even declare a whole bunch of {dollars} in opposition to a battery from a state-based scheme in the event that they join it to a digital energy plant supplier that aggregates obtainable energy after which makes use of it to maintain the electrical energy system steady.
The CER information confirmed the common measurement of the batteries below the scheme was 17 kilowatt hours, which Johnston stated was a lot greater than the continued common of 10-12 kWh.
Eligible batteries are between 5 kWh and 100 kWh, though charges below this system are solely paid as much as the primary 50 kWh.
The chief government of the Power Effectivity Council, Luke Menzel, stated curiosity within the battery program was “off the charts”.
“It underlines just how hungry households are for solutions that can help them manage their energy costs,” he stated.
Spike in batteries
In current months firms have been allowed to promote and set up batteries below the scheme, so long as they weren’t turned on till after 1 July.
Andre Scott, a director at photo voltaic and battery installer 1KOMMA5, stated in Might and June, whole gross sales of photo voltaic and batteries have been up 76% on the identical interval in 2024.
“We’ve also seen a significant spike in battery-only purchases – a 459% increase. If we include July, the demand has been at unseen levels across the board,” he stated.
Scott stated the surge in battery-only installations had come from folks with current photo voltaic programs.
Typical costs for a battery have been between $1,000 and $1,200 a kWh earlier than reductions, he stated. Most batteries have been put in in a method that would offer properties with back-up energy within the case of outages.
Demand ‘has gone nuts’
The director of study and advisory at Inexperienced Power Markets, Tristan Edis, stated the “demand for batteries has gone nuts”.
He stated if the present charge of installations was maintained then inside 5 years there could be about 10,000MW of battery capability put in.
“That’s a big deal when you think we have 20,000MW of coal capacity [in Australia].
He said adding batteries in homes would help to spread the use of solar energy into the evening and cut electricity demand during peak periods – a time, he said, when gas turbines traditionally ramp up.

“[The boom in batteries] completely destroys the business case for a gas turbine and also the high evening prices that coal generators rely on.”
One other revolution
Johnston stated the degrees of curiosity in house batteries was paying homage to a interval between 2008 and 2010 when the rooftop photo voltaic growth took maintain.
“There’s been a latent interest in batteries and people have been waiting for them to get cheaper. This program has improved the financials of it,” he stated.
Because the photo voltaic growth, the quantity that households are paid for feeding electrical energy again to the grid has dropped considerably.
The overall supervisor of distributed vitality on the renewable business’s Clear Power Council, Con Hristodoulidis, stated it had taken 4 years to build up 185,000 put in batteries, however that determine might be at 300,000 by the top of the yr.
“Solar was the first wave with people realising they could have energy independence. I think this is the second wave of a revolution,” he stated.
Menzel stated Australia had grow to be a world chief within the adoption of rooftop photo voltaic with greater than 4m programs now put in.
“The early interest in home batteries echoes the early ramp up in solar.
“This is a sign that with the right support the suburbs will step up again to invest in the efficient, electric technologies that will help them drive down their bills.”
However he stated contemplating the demand up to now, it was “very unlikely the $2.3bn that has been allocated by the government will last through to 2030 as advertised.”
The federal government allotted $2.3bn in ahead estimates for this system, and an additional $1.2bn to 2030-31. The low cost worth per kWh will fall annually as battery costs are additionally anticipated to fall.
In an announcement, the federal vitality minister, Chris Bowen, stated greater than 10,000 folks had already claimed on the scheme “to cut their power bills for good – slashing up to 90% off their energy bill from day one.”
