Synergy Renewable Energy Developments Pty Ltd has proposed a landmark renewable energy project known as the Tathra Wind Farm, situated approximately 15 kilometres east of Eneabba in Western Australia’s Mid West region.
The ambitious development aims to integrate up to 140 wind turbines with a generation capacity of 1,000 megawatts (MW), alongside 500 MW of solar power generation, a battery energy storage system with a capacity of up to 500 MW, and all necessary supporting infrastructure.
This project will connect to the South West Interconnected System (SWIS) through the existing 330 kV transmission line intersecting the development area.
Covering a development envelope of 15,847 hectares, the project is designed to minimise its ecological footprint, with only 1,595 hectares disturbed and no more than 3.44 hectares of remnant native vegetation cleared.
The site spans several farming properties in the Shire of Carnamah, helping to reduce land impact and leverage existing agricultural landscapes.
The proposed turbine blades will reach heights up to 250 metres, matching the height of Perth’s Central Park building, symbolising the project’s scale and the technological advancement of wind generation in the region.
The Tathra Wind Farm is poised to become the largest wind farm in Western Australia, with the combined wind and solar capacity offering a diversified renewable energy solution.
The Mid West region is recognised as one of the best locations in Australia for renewable energy due to its strong wind resources and exceptional solar radiation.
The hybrid nature of the project — incorporating wind, solar, and advanced battery storage — allows for maximised utilisation of the energetic assets, ensuring more consistent power supply and efficiency by storing energy for peak demand periods.
The project is a key component of the Western Australian government’s strategy to transition away from coal-fired power generation by 2030, aligning with the state’s decarbonisation and clean energy goals.
Synergy, a state-owned utility, estimates the cost of the development at $4.5 billion and plans to complete the project in stages.
The use of the existing 330 kV transmission line linking Eneabba to Three Springs will facilitate integration with the SWIS, supporting grid stability and effective power distribution throughout the region.
