The Macarthur Wind Farm is a wind farm in Victoria, Australia, located in Macarthur, Victoria on a 5,500 ha site and it has been permitted to generate up to 420 MW. The wind farm comprises 140 3 MW Vestas V112 wind turbines manufactured in Denmark. It is expected to be 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 project is estimated to cost 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.
