A new study has demonstrated that electricity generation in Broome, Western Australia, can be achieved with over 80% renewable energy at three-quarters of the price of gas-fired (LNG) generation, resulting in total lifetime savings of $321 million.

The study, by advocacy body Sustainable Energy Now (SEN), assessed the feasibility of shifting Broome’s electricity generation to a renewable source.

The study’s release comes at a time when Australia is increasing its efforts to transition to renewable energy, with a target of net-zero emissions by 2050.

The WA Government has committed to reducing its own emissions by 80% by 2030.

Dr Rob Phillips from SEN said the plan would enable any landowner in Broome to install solar on their own rooftop.

He added: “High penetration of renewables with batteries in the Kimberley will drastically reduce the amount of fuel required for generation, increasing resilience in flood events.”

The report was commissioned by the Kimberley’s peak conservation group Environs Kimberley and Lock the Gate.

Environs Kimberley spokesperson Martin Pritchard said: “Broome has the potential to become a leader in renewable energy, and this study shows that the transition to a clean energy future is not only feasible but also cheaper.

“This is a perfect opportunity for the McGowan government to support the transition to renewables in Broome – it fits in perfectly with the State Government’s commitment to emissions reduction.”

The study showed there was an excellent opportunity to move from mostly gas to predominantly renewable energy generation at the conclusion of the existing LNG generation contract in 2027.

This could be achieved by a mix of rooftop PV and solar farms, with substantial battery storage.
