The Yambuk wind farm is the first stage of Pacific Hydro’s four-stage Portland Wind Energy Project (PWEP) in southwest Victoria.\nLocated next to the Codrington wind farm, near Port Fairy, the site was chosen for its ideal wind conditions – it’s average annual wind speed of 30km/h is perfect for producing clean, non-polluting electricity.\nCompleted in 2007, the 30MW Yambuk wind farm comprises 20 wind generators which produce enough energy to meet the annual needs of 35,000 homes per annum, with an average electricity generation of 100GWh per year.
Hampton Wind Park is the first wind energy development in Australia to be initiated, developed and operated privately by a landholder. Founding Hickory Hill Wind Energy after a career operating coal-fired power generation, Hugh Litchfield originally identified the site on his family's farm, initiated the project and conducted wind monitoring for over 18 months, helped by sharing costs of the resource assessment with Integral Energy.\nHampton Park is at Hickory Hill just off the Jenolan Caves road near Hampton, which is atop the Great Dividing Range about 115 km west of Sydney.
Hampton Wind Park has a capacity of 1.32 MW. The wind park consists of two wind turbines each with a maximum capacity of 660 kW. Each wind turbine stands 50 m high and the rotors have a diameter of 47 m. Each rotor consists of three blades and rotates at 28.4 revolutions per minute. The rotors do not turn in very low winds. They start turning when the wind sustains 4 metres per second (14 km/h) and reach nominal generation at 13-16 m/s (46-58 km/h). They stop turning at over 25 m/s (90 km/h) to avoid damage.
During the planning phase, all environmental impacts were assessed in collaboration with the local council. The community was involved in the planning process through regular consultations and several public meetings. Environmental issues such as impact on local flora and fauna, electromagnetic interference, visual amenity and noise were addressed.
Wattle Point wind farm, near Edithburgh on Yorke Peninsula, used to be Australia's largest. Covering an area of 17.5 square kilometres, with 55 wind turbines, and costing AU $180 Million Dollars to construct. The Wattle Point wind farm was officially put into operation in June 2005. It has 55 Vestas V82 Wind Turbines, that produce 91 MW of clean, green renewable energy, or 312,000 MWh or 2% of South Australia's Electricity per year, which is enough to power 52,000 homes. Construction on the site commenced in July 2004 and the site was completed by April 2005, where further tests were carried out before its official opening.
During its peak, there were 162 people employed on the project, while today, there are five full time service technicians employed to operate and maintain the wind farm. The expected life of the wind farm should be 25 years. The towers are 67 metres tall and the blades are 40 metres tall giving the towers a total height to the tip of the blades of 110 metres. Electricity generated by the wind farm is fed directly into Electronet's 132KV main transmission system, and then into the national electricity grid. 3 kilometres from Edithburgh on Sheoak Beach Road, there is a free public viewing area.
The Walkaway Wind Farm, is located in the central west region of Western Australia, near the town of Walkaway, approximately 30 km south east of Geraldton and 12 km inland from the Indian Ocean. The area surrounding Geraldton is one of the windiest regions in Australia. Wind speeds average 20-25 km/h during the cooler months and 25-35 km/h from October to March; a result of the strong seasonal sea breeze coupled with a consistent easterly breeze in the morning – perfect ingredients for wind power.
The Wind Farm is located in open farming country, allowing for optimum spacing of turbines. There are minimal obstructions in the landscape and smooth topography, which is beneficial to the output of the wind farm. Wind farming is compatible with agricultural activities such as stock grazing and broad acre crops. The wind turbines occupy less than one per cent of farm land within the site. Construction of Walkaway began in late 2004, with the wind farm becoming fully operational in January 2006
