WA households flock to energy saving scheme as cost of living soars

More than 500 batteries to store excess solar power are being installed in homes across Western Australia each week, new figures reveal.

The figures show that, since it was first introduced in July 2025, more than 20,000 households have made use of the state government’s $337 million WA Residential Battery Scheme.

The batteries have created more than 300 megawatt hours of energy storage – enough to power the daily needs of 15,000 households. The move tipped to save households as much as $1500 a year on energy costs.

On May 9, home batteries contributed 37.2 per cent of peak demand across the grid, a record amount in WA.

Working with the federal $2.3 billion Cheaper Home Batteries Program, the state government is shooting for a target of 100,000 households to take up the scheme.

Synergy customers receiving a rebate of up to $1300 while Horizon Power customers can receive up to $3800 to install the batteries. More than 5000 homes have also received no-interest loans to help with the costs of installation.

Energy and Decarbonisation Minister Amber-Jade Sanderson said the latest figures showed the state was “on track to become a renewable energy powerhouse”.

“This is an incredible achievement in just over 10 months and proof that people really want to play their part in WA’s energy transition,” she said.

“It also means that consumers are unlocking the full potential from their rooftop solar panels by using less energy from the grid.

“That means real bill savings that have never been more important.”

The government has also tipped $50 million into its Local Battery Manufacturing Program, which provides local battery manufacturers with grants to grow their capacity to provide competitive residential battery products.
