Offshore Wind farms in Australia

Australia has 6 offshore wind farm projects of which none currently operating, none where construction has progressed enough to connect the turbines and generate electricity, none are in the build phase, and none are either consented or have applied for consent. You can access over 80 data sets on each wind farm subject to your access level and drill down to see items such as:

on project 'Australis WA' on Friday, 09 April 2021, the following was announced: 'WA Offshore Windfarm Pty Ltd submitted a referral to the Western Australian Government under Part IV of the Environmental Protection Act 1986 (EP Act). A Preliminary Environmental Risk Review was conducted to identify EPA environmental factors that the Project may have a potentially significant impact on.

The 300 MW wind farm is expected to generate approximately 1,300 gigawatt hours (GWh) of power output each year. This is enough power to supply the equivalent of over 200,000 Western Australia homes.

Initial design plans include:
· 20 to 37 turbines anticipated 8-15 MW unit capacity. Max. rotor diameter: 220m. Max. hub height 154 m.
· Monopile (or similar) foundations. Monopile foundations dimensions 6.5 – 8 m. Monopile foundations depth 30 – 50 m.
· An offshore substation (66 - 132 – 330 kV) with monopile (or similar) foundations. Platform size 800m2.
· Total length 66kVarray cables (dependent upon WTG size) 150 – 280 km
· 330 kV Export Cables. Length 15 km. Burial depth 1-4m.
· Onshore cables
· An onshore substation, which may include new transformers. Footprint 300 x 250 m (20 m high).
· New overhead transmission line supplying energy generated from windfarm to the South West Interconnected System (SWIS), with additional equipment as required, which may include battery storage for fast frequency response to provide stability to the grid.

The windfarm will be located approximately 5.5kms off the coast between Preston Beach and Binningup, 20kms north of Bunbury. The offshore Project area is currently around 26,000 ha and the onshore Project area is 3,300 ha (totalling approx. 29,300ha). The Project area will be refined during future design stages. The onshore Project area covers residential, industrial and farm land near Binningup, Myalup and the Kemerton Strategic Industrial Area (SIA).

The area benefits from consistent wind resource (mean wind speeds greater than 8.5 m/s at 150m elevation), favourable bathymetry with water depths <20m (Max. water depth at turbine locations 16 m), and existing infrastructure that enables effective connection to Western Australia's South West Interconnector System (SWIS) electrical grid. In addition, the location is of preference due to the low population density.

Site selection for the landfall site and onshore infrastructure is ongoing although it will most likely be located at the southern end of the windfarm towards Myalup. The proposed connection point to the Western Australia's South West Interconnector System (SWIS) electrical grid is to the Kemerton substation (330 kV). The substation is located approximately 14 km east of nearest WTG (and 7.5km from the coast).

The project will require a range of environmental and statutory planning permits and consents. It is likely the project will be deemed a significant proposal and assessed under Part IV of the Western Australian Environmental Protection Act 1986 (EP Act) through a Public Environmental Review (PER). Planning approval will also be required under the Western Australian Planning and Development Act 2005 (P&D Act). The project will also require approval under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) for impacts to matters of national environmental significance (MNES).'
