In January 2023, the Fitzroy River peaked at 15.81 metres — the highest flood level in recorded Western Australian history. The Great Northern Highway bridge at Fitzroy Crossing, which had stood since 1974, was severely damaged and closed. Communities across the Fitzroy Valley were cut off from road access for weeks, exposing a critical vulnerability in the region's energy supply chain.
When the roads flood, the fuel stops
Remote communities in the Fitzroy Valley receive their power from diesel and gas generation. That fuel is delivered by road — the same roads that flood when the Fitzroy River rises. When the 2023 floods cut road access, fuel resupply for diesel generators was disrupted across multiple communities, threatening power continuity for health clinics, schools, water pumps and households relying on powered medical equipment.
For communities like Bayulu, located just 10 kilometres south of Fitzroy Crossing, the experience was a stark demonstration of what happens when energy supply depends entirely on road-based logistics. Climate science projects that severe flood events of this scale will occur more frequently in the Kimberley region as temperatures rise and weather patterns intensify.
The human cost of energy insecurity
The impact of power disruption in a remote community is not an inconvenience — it is a health and safety emergency. When power fails in a community where wet-season temperatures routinely exceed 40 degrees Celsius, the consequences fall hardest on the most vulnerable: elderly residents, people with disabilities, those dependent on refrigerated medications and powered medical equipment, and families with young children.
During the 2023 floods, disability support providers operating in the valley observed the direct impact of energy insecurity on NDIS participants — highlighting the link between energy reliability and the delivery of essential services that are normally taken for granted in metropolitan Australia.
Solar and batteries change the equation
A solar and battery system generates power from sunlight — which is available regardless of road conditions. When roads flood, a community with solar and battery storage continues to generate electricity. The diesel generator becomes a backup rather than the primary supply, and the community's vulnerability to supply chain disruption is fundamentally reduced.
This is not a theoretical argument. Communities across the Kimberley and Northern Territory with solar and battery systems maintained power during weather events that would have caused extended outages under diesel-only supply. The Cockatoo Springs community near Kununurra, for example, now operates on 63% renewable energy following its standalone power system upgrade — with diesel consumption reduced by approximately 35,000 litres per year.
Energy resilience is climate adaptation
The 2023 Fitzroy River floods were not a one-off event. They were a preview of the Kimberley's climate future. For communities in flood-prone areas, solar and battery systems are not just about saving money on power bills — they are critical climate adaptation infrastructure that keeps the lights on, the water pumping and the clinic running when the roads are under water. A feasibility study is the first step to understanding what that system would look like for your community.
The experience of the 2023 floods has become a powerful narrative in grant applications for Fitzroy Valley communities seeking funding for renewable energy feasibility studies. It demonstrates, in concrete terms, why energy independence matters — and why communities cannot afford to wait for someone else to solve the problem for them.
