Construction has officially begun on the 470 MW Parron Maam Marang Wind Farm in Western Australia, marking the start of the state’s largest wind farm project to date and the biggest wind project to enter construction in Australia in more than two years.
Located near Badgingarra in the Wheatbelt region, about 200 km north of Perth, the project will have 78 Vestas V162-6.2 MW EnVentus wind turbines.
Once operational, the facility is expected to generate enough renewable electricity to power 350,000 homes. This will support Western Australia’s transition towards a cleaner and more diversified electricity supply.
The construction milestone was announced by Western Australia’s Energy and Decarbonisation Minister, Amber-Jade Sanderson, on October 24, 2026. The project is expected to become operational by late 2028.
The developer’s community framework also proposes a benefit fund based on A$1,000 per MW over the project’s life. This is the equivalent of A$470,000 annually (calculated against the planned 470 MW capacity). Additionally, the final funding arrangements and distribution would depend on the scheme’s implementation.
Parron Maam Marang Wind Farm construction and project team
Atmos Renewables, which developed the project in partnership with Parron Developments, now owns the wind farm outright. The project is also expected to create up to 400 jobs during peak construction. This will provide opportunities for local workers, contractors and suppliers.
Additionally, a key construction contract was awarded in September 2026 to GenusPlus Group. GenusPlus secured a contract worth A$135 million to design and construct the project’s 330 kV terminal and associated transmission lines. The contractor’s scope covers the grid connection infrastructure. It will, however, not cover the wind farm’s internal balance-of-plant works.
Parron Maam Marang Wind Farm transmission connection will also link the project to Western Australia’s South West Interconnected Network. This will help deliver the electricity generated by Atmos’ Parron to the state’s grid.
Furthermore, the grid connection is particularly significant because Western Power proposed a major transmission network augmentation to facilitate the project. The Economic Regulation Authority of Western Australia also approved a waiver of the regulatory test for the proposed works on June 4, 2026. This marked an important regulatory step towards accommodating the new generation capacity.
Danish wind turbine manufacturer Vestas will supply the project’s 78 V162-6.2 MW turbines. The company has also been involved in other wind energy developments across Western Australia. This includes the Waddi project and the Warradarge Wind Farm expansion.
Synergy power purchase agreement supports construction
The Parron Maam Marang Wind Farm project’s construction also follows a long-term power purchase agreement (PPA) signed with Synergy in March 2026. Synergy is the Western Australian government-owned electricity generator and retailer. The agreement also provided greater revenue certainty for the project and helped secure the private investment needed to proceed.
The wind farm is also supported by the Australian Government’s Capacity Investment Scheme (CIS). CIS is designed to encourage investment in new renewable energy generation and storage capacity.
Parron Maam Marang is also among several wind energy projects progressing in Western Australia as the state prepares for the retirement of its remaining coal-fired power generators by the end of the decade.
Other developments include Neoen’s Narrogin Wind Farm, Bright Energy Investments’ Warradarge Wind Farm Stage 2 and the Kondinin Wind Farm. Alinta Energy’s proposed Marri Wind Farm, which has a planned capacity exceeding 550 MW, could also become a major addition to the state’s renewable energy pipeline.
Parron Maam Marang Wind Farm to support Western Australia’s energy transition
The project is also expected to provide employment and supply-chain opportunities throughout construction. This will be followed by about 15-20 skilled operations and maintenance positions during its anticipated 30-year operating life.
Atmos Renewables has also committed to working with local suppliers and First Nations businesses. This is while a community benefit fund is planned to support broader social and economic outcomes in the Shire of Dandaragan and surrounding Wheatbelt communities.
Furthermore, Parron Maam Marang Wind Farm project will complement Atmos Renewables’ other investments in Western Australia, including the 100 MW/400 MWh Merredin Battery Energy Storage System. Merredin has progressed into commissioning.
With construction now underway, Parron Maam Marang represents a significant addition to Australia’s renewable energy construction pipeline. This will be alongside others such as the Amazon-backed Winton North Solar and Battery Project. Its delivery also will increase Western Australia’s wind generation capacity. It will also help replace electricity supply expected to be lost as coal-fired generation retires.
