More families across Western Australia's Kimberley region will soon benefit from a joint government program providing rooftop solar, lower energy bills, and clean power.

The first switch was flicked on Horizon Power's Kimberley Communities Solar Saver (KCSS) initiative in June 2024 in the town of Warmun, where 0.42 megawatts of rooftop solar was installed, reducing reliance on costly diesel generation and lowering electricity costs for 80 homes with pre-paid meters.

KCSS has since expanded to Bidyadanga, Ardyaloon, Yungngora and Beagle Bay, with 1.38 megawatts of rooftop solar installed across 125 systems in the five communities.

Energy‑saving credits to more than 430 homes in five remote communities have saved each on average $450 per year.

Now the KCSS is rolling out its sixth Kimberley clean energy hub in Mowanjum - expected later this year - for residents there unable to afford individual rooftop solar.

Almost $200,000 of energy-saving credits have been invested since June 2024 by the federal and state Labor governments in five First Nations communities across the Kimberley.

Solar panels are installed in selected homes, with credits shared across the community.

Kimberley MLA Divina D'Anna said she was proud to help families ease a much-needed financial burden, and also ensure reliable power was available for more and more remote communities.

"We are supporting remote communities in the Kimberley with cleaner, more affordable energy," she said.

The KCSS project is funded via the $10.56 million state and federal government Community Solar Banks partnership.

Commonwealth climate change and energy assistance minister Josh Wilson said such programs were essential as the energy transition accelerates and renewables start to outpace fossil fuel generation.

"We are making sure the shift is equitable and accessible to all Australians," he said.

WA energy and decarbonisation minister Amber-Jade Sanderson said houses traditional in the most remote parts of the country had struggled to pay for rooftop solar.

"We are seeing real benefits now, with cleaner, more affordable and reliable power," she said.

Horizon Power CEO Krystal Skinner said the program is "delivering practical benefits for households that historically had been unable to access rooftop solar".

"Our approach is based on sustained engagement with community leaders and Traditional Owners to ensure energy solutions meet local needs and improve long term reliability."
