Emu Downs Wind Farm (WA)

Originally completed in 2006 and acquired by APA in 2011, the Emu Downs Wind Farm is one of Western Australia's largest green energy initiatives. Located 30 kilometres east of Cervantes and approximately 200 kilometres north of Perth, Emu Downs generates electricity from wind powered turbine technology. The wind farm has a capacity to produce 80 megawatts of electricity at peak, and to supply 50,000 homes per year.

Emu Downs is providing a sustainable energy solution for Western Australia. Electricity and renewable energy certificates are purchased by Synergy Energy and Origin Energy.

Emu Downs Solar Farm (WA)


APA Group has developed the Emu Downs Solar Farm (EDSF) in Badgingarra, Western Australia. The solar farm comprises the Photovoltaic (PV) array and associated works, such as electrical, civil and supervisory control and data acquisition (SCADA). The output from the EDSF has the potential to save 35,000 tonnes of greenhouse emissions annually.

The EDSF has resulted in the formation of Western Australia’s first co-located wind and solar farm. The EDSF was designed to fill the energy gap between the stronger wind patterns in the morning and afternoon within the region. The energy produced from the combined renewables facility, will have the potential to provide nearly 60,000 Western Australia homes with energy.

The EDSF utilises the NEXTracker single axis tracking system to optimise the efficiency of the PV panels. The expected Operational Design Life for EDSF is at least 25 years.

Key project statistics:

  • 75,168 PV panels.
  • 10,480 piles.
  • 340-kilometre Direct Current (DC) cabling.
  • 10-kilometre High Voltage (HV) cabling.
  • 38,000 PV panel clips.
  • PV panels covering 70 hectares of land.

Sustainability and environmental conservation were at the forefront in the construction of Emu Downs Solar Farm. All personnel were dedicated to achieving the highest standards of environmental care on site.

Environmental statistics:

  • 960 cubic metres of cardboard recycled.
  • 15 tonnes of metal removed.

APA is committed to providing a safe work environment with zero harm to employees, contractors and visitors. This ethos underpinned all activities no matter how small.

Safety statistics:

  • 73,000 man hours.
  • Over 200 personnel onsite.
  • No Lost Time Incidents.
  • Over 260 hazards reported.
  • 178 safety conversions.

Badgingarra Wind Farm (WA)

The Badgingarra Wind Farm is being constructed just to the north of APA’s existing 80-megawatt Emu Downs Wind Farm, and the recently completed 20-megawatt Emu Downs Solar Farm. The Badgingarra Wind Farm will consist of 37 Siemens 3.6-megawatt wind turbines installed with a hub height of 85 metres and tip height of 150 metres.

The new wind farm will generate 130 megawatts of power into the Western Power electricity grid, creating a 230-megawatt renewable energy precinct near Cervantes, approximately 180 kilometres north of Perth, in Western Australia.

The $315 million APA development is underpinned by an agreement with Alinta Energy for the purchase of all the energy, and the Large Scale Renewable Generation Certificates generated by the wind farm through to December 2030.

The potential energy output from Badgingarra Wind Farm is equivalent to the power required for more than 115,000 Western Australian homes. This clean energy initiative will also have the ability to save more than 420,000 tonnes of greenhouse gas emissions annually.

In addition to the positive environmental impacts, the wind farm will also positively impact the residents of surrounding local towns and communities. This will stem from the creation of local employment opportunities and local businesses stimulation due to increased construction traffic and personnel.

Construction of the wind farm commenced in November 2017 and is expected to be complete in early 2019.

North Brown Hill Wind Farm (SA)

North Brown Hill Wind Farm at Hallett, South Australia consists of 63 wind turbines with a total capacity of 132.3 megawatts. It is owned by EII2, in which APA has a 20.2% interest with ICG (39.9%) and Osaka Gas Company Ltd (39.9%). The wind farm has a 25-year offtake arrangement with AGL Energy for both the electricity generated and the renewable energy credits produced.
