The Project will be an offshore windfarm, generating electricity that will be fed into the Western Australia South West Interconnector System (SWIS) electricity grid utilising both subsea and overhead transmission cables.
The Project will comprise up to 37 offshore wind turbine generators (WTGs) as well as the supporting offshore and onshore electrical assets to allow the transfer of energy generated by the wind farm to the existing electricity network. The size of individual WTG’s is yet to be determined, with an anticipated capacity ranging between 8 MW and 15 MW. The preferred turbines are the larger (15 MW) WTGs, as fewer will be required (20), which will result in less construction activity and reduced visual impact.
The proposed 300MW of installed electrical capacity is expected to generate approximately 1,300 gigawatt hours (GWh) of power output each year from a clean, renewable energy source. This is enough power to supply the equivalent of over 200,000 Western Australia homes each year for the lifetime of the project.
The project is currently in the pre-planning application stage. If approved, early construction work would begin in the summer 2024/25 and the project would be completed and operational in summer 2026/27.
The Project will be located approximately 5.5kms off the coast between Preston Beach and Binningup, 20kms to the north of Bunbury. The exact offshore layout of the windfarm will be designed after site surveys.
As the project is in early stage, site investigations still need to be conducted which will help to determine the exact offshore layout of the windfarm. These investigations will cover an area of around 60 sq km.
The proposed 15MW turbines are approximately 150m tall to the centre of the rotor (nacelle). The blades are 108m each in length, giving a base to blade tip height of around 260m.
Yes. The closest point of the windfarm would be around 5.5kms from the coast and over 7km from the nearest built up area (Binningup). Although they will be in the distance, the turbines will be a visible from the coast.
The proposed grid connection is to the Kemerton substation.
