WA Offshore Windfarm

The proposed offshore windfarm will have a generation capacity of up to 300 megawatts (MW) and is proposed to be located approximately 5.5 kilometres off the WA coast between Preston Beach and Binningup, 20 kilometres north of Bunbury. The facility will comprise up to 37 wind turbines and is proposed by WA Offshore Windfarm, a subsidiary of Australis Energy. 

Key features of the Western Australia Offshore Windfarm project include:

  • an offshore windfarm with up to 300MW of generation capacity
  • 1,300 gigawatt hours (GWh) of power output each year
  • up to 37 offshore wind turbine generators, and 
  • supporting offshore and onshore electrical assets. 

Electricity generated from the windfarm will be fed into the WA South West Interconnected System (SWIS) electricity grid using both subsea and overhead transmission cables, with the proposed grid connection at Kemerton substation.
