The Macarthur Wind Farm is a wind farm in Victoria, Australia, located in Macarthur, Victoria on a 5,500 ha site which generates up to 420 MW. It is the largest wind farm in the Southern Hemisphere, generating enough power for 220,000 homes and abating 1.7 million tons of greenhouse gases annually. The wind farm comprises 140 3 MW Vestas V112 wind turbines manufactured in Denmark.
The project cost about A$1 billion and was fully operational in January 2013. It was constructed by Vestas and Leighton Contractors. The first turbines were connected to the grid in September 2012.
The project was developed by a joint venture formed by AGL Energy and Meridian Energy. In 2013, Meridian sold its share to Malakoff Corporation Berhad.
