Western Sydney has become one of the fastest-growing markets for home batteries in the country, as households look for ways to reduce soaring energy bills ahead of a looming deadline.
VoltX Energy Chief Operating Officer David Sedighi said households were becoming increasingly focused on controlling recurring household expenses before generous government rebates were further reduced.
“We’ve seen a marked 350% increase in households inquiring about a home battery installation before the federal Cheaper Home Batteries Program discount falls by 16% or around $900 from January 1, 2027,” said Mr Sedighi.
“Homes in suburbs like Marsden Park, Rouse Hill, Baulkham Hills, Liverpool, Blacktown, Werrington and Campbelltown are now leading home battery uptake, while neighbouring leafy suburbs such as Ryde are only now beginning to get on board.
“Gosford on the Central Coast is also emerging as a major battery market outside of Sydney.”
The surge comes as Australia records unprecedented demand for household energy storage with new figures showing 276,011 home batteries were installed in the first half of 2026, 52 per cent more than in the previous six months.
“With family budgets under pressure, people start looking very closely at where they can save money every month,” Mr Sedighi said.
“You can now install a 28kWh battery set up for under $4000, which would make the average household completely self-reliant from the grid immediately and the return on investment realised in around two years.”
Mr Sedighi warned households considering a home battery not to wait or risk missing out.
“When the rebate dropped earlier this year we saw many consumers miss the deadline, because the battery has to be installed, not just ordered. There’s about 10 weeks to get yourself sorted and it’s not a lot of time.”
NSW is Australia’s leading state for household battery capacity, with homes holding 2,911 MWh of battery storage at the end of March 2026.
“With a Virtual Power Plant (VPP), we are seeing many households not only fully eliminate their power bills, but actually sell to the grid.”
Mr Sedighi said they were also seeing early adopters return to increase their storage.
“People who installed solar several years ago are now coming back and adding storage because they want to use more of the electricity they’re already generating.”
Mr Sedighi warned consumers to be wary of the fine print.
“Not everyone installs lithium iron phosphate battery systems with 10-year performance and workmanship warranties, using CEC-accredited technicians like we do,” he said.
