Underground cables, turbine parts: Fresh construction milestones for WA’s largest wind farm

Construction on a 103-megawatt (MW) expansion of one of Western Australia’s best performing wind farms continues to hit new milestones on its way to delivering the state’s largest wind farm.

Leading WA energy generator and retailer Synergy recently confirmed on LinkedIn that eight wind turbines have now been erected at the Warradarge Wind Farm Stage 2 project, located approximately 260 kilometres north of Perth in the Shires of Coorow and Carnamah in the Mid West Region of Western Australia.

The $400 million, 100 MW expansion was confirmed in January 2025 by Bright Energy Investments, a joint venture between Synergy and Potentia Energy, with construction of the 30 new Vestas V136-3.6 MW wind turbines beginning in the middle of last year.

The 30 new wind turbines are being installed among the existing 51 already in operation and will increase the total capacity of the Warradarge Wind Farm to 283 MW.

Wind turbine tower sections, hubs, nacelles, and turbine blades are being transported by truck via the Brand Highway from the Port of Henderson, 300 kilometres away, just south of Perth.

In addition to the eight turbines already erected, Synergy also confirmed that all underground cables have also now been installed.

Once completed next year, the Warradarge Wind Farm will be the biggest wind farm in the South West Interconnected System (SWIS).

Already one of the best performing wind assets in Australia – recording an impressive capacity factor of 60.5 per cent in February and 55 per cent in January, for example – completion of its second stage expansion will help to cement Warradarge Wind Farm as one of Australia’s most important wind farms.
