Developer Behind Australia’s Biggest Operating Wind Farm Advances Plans for New 50-Turbine Project

Why It Matters

Bottle Tree’s 400 MW capacity could significantly boost clean generation in a coal‑heavy region, while its approval will signal how renewable projects fare under a less renewables‑friendly state administration.

Key Takeaways

• Westwind submitted 1,168 pages to EPBC for 400 MW Bottle Tree project.
• Project located 16 km NE of Roma, near coal‑seam‑gas fields.
• State approval granted 2023; federal review still pending.
• Eight turbines removed and routes altered to protect koala habitat.
• Westwind also pursues 1.5 GW Cameron Downs wind‑battery venture in Queensland.

Pulse Analysis

Westwind Energy, the firm behind Victoria’s 1.3 GW Golden Plains wind farm, is now steering its attention to Queensland with the Bottle Tree Energy Park. The 400 MW, 50‑turbine scheme sits in the Maranoa region, a landscape dominated by coal‑seam‑gas extraction. By advancing the project through the federal Environment Protection and Biodiversity Conservation (EPBC) process, Westwind aims to secure the green light needed to connect the farm to existing transmission corridors that stretch west from Brisbane. Success would diversify the region’s energy mix and add a sizable chunk of renewable capacity to Australia’s national grid.

The EPBC review focuses heavily on biodiversity, as the site hosts koalas, migratory birds such as white‑throated needletails, and several endangered reptiles. Westwind’s submission includes detailed flora and fauna surveys, and the company has already responded by dropping eight turbines and realigning access roads to spare critical habitat trees. These mitigation steps illustrate a growing industry trend: developers are pre‑emptively redesigning projects to address ecological concerns before they become regulatory roadblocks, thereby shortening approval timelines and reducing community opposition.

Political dynamics add another layer of complexity. Queensland’s recent shift to a Liberal government led by Premier David Crisafulli has seen a rise in call‑in notices that subject approved projects to ministerial review, especially in regions with strong fossil‑fuel interests. For Westwind, navigating this environment will be as crucial as meeting environmental standards. The outcome of Bottle Tree could set a precedent for future large‑scale wind‑battery ventures, such as the 1.5 GW Cameron Downs Energy Park, influencing investor confidence and the pace of Australia’s transition to a low‑carbon economy.
