The Project will be an offshore windfarm, generating electricity that will be fed into the Victorian electricity grid within the National Electricity Market (NEM) utilising both subsea and overhead transmission cables.
The Project will comprise up to 75 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 (40), which will result in less construction activity and reduced visual impact.
The proposed 600MW of installed electrical capacity is expected to generate approximately 2,600 gigawatt hours (GWh) of power output each year from a clean, renewable energy source. This is enough power to supply the equivalent of over 400,000 South Australian homes each year for the lifetime of the project.
The project has reached the ‘scoping’ stage of the Environmental Impact Assessment (EIA). The project has been deemed by the State Government to be Impact Assessed and will require that an Environmental Impact Statement (“EIS”) be prepared to consider the environmental, social and economic effects of the project. Once the Scoping Requirements for EIS have been agreed, the EIA leading to the EIS can begin, involving surveys and wider stakeholder engagement. Australis aims to achieve planning permission, and the necessary consents and permits, in order to commence detailed design and procurement in 2023.
The Project will be located approximately 10kms off the coast from Kingston SE, and 230kms to the south of Adelaide. The exact offshore layout of the wind farm 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 wind farm. These investigations will cover an area of around 135 sq km.
The proposed 15MW turbines are approximately 150m tall to the centre of the rotor (nacelle). The blades are around 108m each in length, giving a base to blade tip height of around 260m.
Yes. The closest point of the windfarm would be around 7kms from the coast and over 12kms from the nearest built up area (Kingston SE). Although they will be in the distance, the turbines will be a visible from the coast.
The proposed grid connection is to the Black Range or South East substation.
