Wind power has become a significant energy source within South Australia over the past decade. As of October 2011, there is an installed capacity of 1,205 MW, which accounts for 21 per cent of electricity production in the state.[1] This represents around half of the nation's installed wind power capacity. The rapid growth of wind power in South Australia has enabled the state to achieve its target of sourcing 20% of electricity from renewable energy sources three years ahead of schedule.[2]
The development of wind power capacity in South Australia has been encouraged by a number of factors. These include the Australian Government's Mandatory Renewable Energy Target, which require electricity retailers to source a proportion of energy from renewable sources, incentives from the South Australian Government including a supportive regulatory regime and a payroll tax rebate scheme for large scale renewable energy developments. Also the state's proximity to the Roaring forties means there are high quality wind resources for wind farms to exploit.
The load factor (or capacity factor) for South Australian wind farms is usually in the range 32-38%. This means that a wind farm could typically produce between 32 and 38% of its nameplate capacity averaged over a year.[3]
Renewable energy context
South Australia leads the nation in terms of renewable energy investment. Being a leader in green energy South Australia with 8% of nation’s population captured 56% of nation’s grid connected wind power, 30% of solar power and 90% of its geothermal developments.[4] With the advantage of being known for having some of the windiest and sunniest places in Australia, South Australia is considered to be a target for green energy investors.
Already the federal government has spent AUD 1 million dollars to hire Macquarie Capital, WorleyParsons and Baker & McKenzie to investigate the state’s electricity transmission capacity and project plans for the expansion of renewable energy in South Australia.[5]
Wind energy is a popular alternative to the fossil fuels like coal, gas and oil in terms of better sustainability, economically feasible and environmental friendly. The Australian Energy Market Operator (AEMO) 2010 SA Supply Demand Outlook estimates that in 2009-10, 18% of the state’s energy production came from wind power.[6]
South Australia is the largest producer of wind energy in Australia, as of April 2011 hosting 49% of the nation’s installed capacity.[7] There are currently 13 wind farms operating across the state with an installed capacity of 1018 MW of power. A further 184 MW of wind farm projects are under construction. South Australia has been highly successful in attracting a significant portion of the investment in wind energy in the country. In mid-2009, RenewablesSA was established to encourage further investment in renewable energy to the state.[8]
Wind farm overview
![](http://upload.wikimedia.org/wikipedia/commons/thumb/7/7a/Lake_Bonney_wind_farmDKC1.jpg/220px-Lake_Bonney_wind_farmDKC1.jpg)
In 2003 the only large wind turbine in South Australia was a 0.15 MW unit at Coober Pedy and by early 2004 there was 34 MW of installed wind power capacity.[3]
As of December 2010, South Australia had thirteen operational wind farms, with an installed capacity of 1,018 MW. South Australia had half of the nation's installed wind capacity, despite only making up 8% of Australia's population. A further 184 MW of projects were under construction. It is estimated that wind power provided 14% of South Australia's energy demand in 2008/09.[9][10][11]
AGL Energy is a major developer of wind farms in Australia with many new projects in production or planned. By 2011 the company expects to produce 460 MW using 232 wind turbines in South Australia, supplying an estimated 250,000 households with electricity.
As of October 2011, South Australia had an installed capacity of 1,205 MW, accounting for 21 per cent of electricity production.[1]

South Australia has provided regulatory certainty for wind farms, and the government has implemented land use planning policies which represent national best practice for accommodating wind farms.[10] On 2 June 2009, Premier Mike Rann announced plans to increase South Australia's renewable energy production target to 33% by 2020, well above the national target of 20% by 2020.[10]
Completed wind farms
![](http://upload.wikimedia.org/wikipedia/commons/thumb/5/51/Hallett_wind_farm_2010.jpg/220px-Hallett_wind_farm_2010.jpg)
Hallett Wind Farm (350 MW)
Hallett 1 wind farm, consists of 45 Suzlon S88 turbines each of a rated 2.1 megawatt (MW) for a total of around 95 MW. It is in the Mid-North of South Australia adjacent to an existing 180 MW gas fired peaking power plant.[13] The wind farm construction was carried out by Suzlon Energy Australia Pty. Ltd. Hallett 2, 4 and 5 are also complete.
Lake Bonney Wind Farm (278.5 MW)
Lake Bonney Wind Farm was built in three stages. Stage 1 consisted of 46 turbines each having a rated capacity of 1.75 MW (total 80.5 MW) and was finished in March 2005. Construction of Stage 2 began in November 2006 and was finished around April 2008. Stage 2 consisted of 53 turbines of 3 MW (total 159 MW). Stage 3 consists of 13 turbines of 3 MW (total 39 MW). The combined capacity of the three stages are 278.5 MW making it the biggest wind farm in Australia at the time of completion. [14]
Waterloo Wind Farm (111 MW)
The Waterloo Wind Farm is a 111 MW wind farm which was completed in 2010 at an estimated cost of $300 million.[12] Thirty-seven Vestas V90 3 MW turbines stretch over the 18 km wind farm site and are connected through a 33 kilovolt (kV) internal reticulation network to the wind farm substation. The wind farm is approximately 30 kilometres south-east of the township of Clare and 100 km north of Adelaide.[15]
Snowtown Wind Farm (99 MW)
The first stage of the Snowtown wind farm, was substantially completed by October 2008. First power went to the grid in December 2007. The official opening took place on 2 Novembernd, 2008.[16] It is located on the Barunga Range of hills west of Snowtown in the Mid-North of South Australia and around 150 km north of the state capital, Adelaide.
Wattle Point Wind Farm (91 MW)
![](http://upload.wikimedia.org/wikipedia/commons/thumb/2/20/Wattle_Point_wind_farm.jpg/220px-Wattle_Point_wind_farm.jpg)
Wattle Point Wind Farm is near Edithburgh on the coast of South Australia. When it was officially opened in June 2005 it was Australia's largest wind farm at 91 MW. The installation consists of 55 wind turbines and was built at a cost of 165 million Australian dollars. In April 2007, Alinta sold Wattle Point Wind Farm to a wholly owned subsidiary of the ANZ, Energy Infrastructure Trust, for 225 million Australian dollars.[3]
The District Council of Yorke Peninsula approved a second wind farm near Wattle Point, but the development has not proceeded due to insufficient capacity in the main power transmission line.[3]
Mount Millar Wind Farm (70 MW)
![](http://upload.wikimedia.org/wikipedia/commons/thumb/f/f1/Mt_Millar_wind_farm_DKC1.jpg/220px-Mt_Millar_wind_farm_DKC1.jpg)
Mount Millar Wind Farm (previously called Yabmana) is situated on an escarpment between the towns of Cowell and Cleve located 100 kilometres southwest of Whyalla. The 35 wind turbines are positioned on the elongated Mount Millar site (about 7 kilometres in length) to maximise wind exposure. The wind farm can generate up to 70 megawatts of electricity and will provide enough energy to meet the needs of about 36,000 typical households.[17]
The Mount Millar Wind Farm is different from other SA wind farms, due to the turbines being a direct drive machine that don't have gear boxes. This is why the nacelle of these turbines has a larger diameter than most.[3] The wind farm connects to ElectraNet’s existing transmission network at Yadnarie Substation, via a new 33 km 132kV overhead transmission line and substation.[17]
Construction of this wind farm started in late 2004 and was completed in December 2005. Power production started in February 2006.[3] The $130 million project was developed by Tarong Energy Corporation Ltd and is owned by Meridian Energy.[17]
Cathedral Rocks Wind Farm (66 MW)
Cathedral Rocks Wind Farm is in a remote coastal area located near the southern tip of the Eyre Peninsula in South Australia, about 30 km south west of Port Lincoln. The site covers an area of about 29 km², with a coastal exposure of nearly 11 km and is private farming land.[18] Cathedral Rocks Wind Farm has 33 wind turbines, with a combined generating capacity of 66 MW of electricity. The wind farm was commissioned in September 2005.[3]
Before the wind farm was built, extensive environmental and cultural studies were conducted. Surveys undertaken included the assessment of potential impacts to Aboriginal and European cultural heritage, flora, visual amenity, noise levels, birds and other animals. Construction of the wind farm was undertaken with consideration for the environment.[18]
Clements Gap Wind Farm (56 MW)
In February 2010, Pacific Hydro opened the 56.7 MW Clements Gap Wind Farm. The opening ceremony was overseen by South Australian Premier Mike Rann.[11][19]
The wind farm is located in South Australia’s mid-north. The project has 27 x 2.1 MW Suzlon wind turbines, which generate enough electricity for 30,000 homes.[19]
Canunda Wind Farm (46 MW)
![](http://upload.wikimedia.org/wikipedia/commons/thumb/a/ac/Canunda_wind_farm_DKC1.jpg/220px-Canunda_wind_farm_DKC1.jpg)
Canunda Wind Farm is a $92.5 million, 46 MW wind power project located on grazing land approximately 16 kilometres south of Millicent.[20] The wind farm is made up of 23 Vestas 2.0 MW wind turbines, together with an underground electrical cable network, access tracks, crane hardstandings, wind monitoring masts and a 33kV double-circuit distribution line. Each turbine consists of a 67 metre high tower and 40 metre long blades, and so are 107 metres in height to the tip of the blade. These wind turbines rotate at speeds between 9 rpm and 19 rpm, depending on the wind speed. The Canunda Wind Farm was opened by the Premier of South Australia, Mike Rann, on 31 March 2005.[20]
The Canunda Wind Farm provides a number of benefits to the local and wider community, including clean electricity generation, enhanced agricultural viability of the farms involved and increased diversity of electricity supply for South Australia and the south east in particular. There has also been widespread community interest in the project and site tours have commenced.[20]
Starfish Hill Wind Farm (34.5 MW)
![](http://upload.wikimedia.org/wikipedia/commons/thumb/f/f6/StarfishHill.jpg/220px-StarfishHill.jpg)
Starfish Hill Wind Farm is near Cape Jervis on the Fleurieu Peninsula. It comprises 23 turbines of 1.5 MW each, with 8 turbines on Starfish Hill and 15 on the nearby Salt Creek Hill, with a combined generating capacity of 34.5 MW of electricity. Starfish Hill Wind Farm was commissioned in September 2003.[21]
Starfish Hill Wind Farm provides enough energy to meet the needs of about 18,000 households, representing 2% of South Australia’s residential customers, and adds about 1% to the available generation capacity in South Australia. The Project was developed by Starfish Hill Wind Farm Pty Ltd, recently sold by Tarong Energy.[21]
Impacts
The increasing proportion of renewable energy in the state has caused a significant decrease in the emissions intensity of electricity generation in South Australia. This means that, even though electricity demand is increasing, the total emissions from generation has been in decline.[22]
The rapid development of wind power in South Australia has led to direct economic effects from the construction and operation of wind farms. There has been a total of $2.8 billion in wind power investment up to October 2011 which is estimated to have created 3000 direct and indirect jobs.[23] Recent studies into the economic effects of wind farms have reported that a 50 MW installation pays host landholders some $250,000 per year, is constructed by workers who spend up to $1.2 million locally and contributes up to $80,000 annually to community projects.[24]
Policies to streamline the approval process for wind farm developments have met with some community opposition. Specific concerns have been raised by rural residents who claim that wind farms have an unacceptable impact on property values, health and the environment.[25] However, a study by the CSIRO based on data collected on developments in New South Wales, Victoria and South Australia concluded that there is a high degree of community support for wind farm developments from those who do not seek media attention or political engagement to express their views.[26]
South Australian electricity prices are the 3rd-highest out of Australia's five states.[27] The 2013 South Australian Electricity Report noted that increases in prices were "largely driven by transmission and distribution network price increases".[28] In contrast, the Australian Energy Market Operator (AEMO) has noted that the South Australian wholesale prices are lower than they have been since the start of the national electricity market, and that the wind “tends to depress the South Australian regional prices”.[29] The Government stated that the price increase due to the Carbon Tax was approximately half of that experienced by other States due to the high installed capacity of wind and gas-fired generation.[30]
2011 Renewable Energy Plan
In October 2011 the South Australian state Government released a renewable energy plan proposing a range of measures including:
- a revised renewable energy target of 33% of the state's electricity production coming from renewable sources by 2020
- a ban on new coal-fired power stations
- greater involvement of local government in the development approval process to promote more effective community engagement
- investigations into increasing the capacity of transmission lines to support renewable energy developments including wind energy
- no wind farms allowed within one kilometre of any home unless agreement is reached between the developer and the home owner.
