Wind power in Australia is clean and renewable and a typical wind turbine can meet the energy needs of up to 1000 homes. The technology is proven, fast to build and economical compared with other renewable energy technologies.[1] In 2006, there were 27 wind farms operating in Australia.

Australia is the highest emitter of greenhouse gases per capita in the developed world[2] [3] and wind power is well placed to grow and deliver greenhouse gas emission cuts on a cost competitive basis. A typical 50 megawatt (MW) wind farm in Australia can reduce greenhouse gas emissions by between 65,000 and 115,000 tonnes a year.[4]

Overview

The information centre near the base of one of the towers at Wattle Point Wind Farm

Australia has excellent wind resources by world standards. The southern coastline lies in the roaring forties and hundreds of sites have average wind speeds above 8 or even 9 m/sec at 50 m above ground (hub height of a modern wind generator). Southwest Western Australia, southeast South Australia, western Victoria, northern Tasmania and elevated areas of New South Wales and Queensland all have very good wind resources. Several states engaged in systematic wind speed monitoring in the 1980s and 1990s, the results of which are publicly available.[5]

At the end of 2006, Australia had installed electricity generation capacity from wind power of 817 MW[6] and nationally wind farms contributed about 1% of total electricity production. In the state of South Australia, this figure was much higher at 9.2% (2005). Australian wind farms produce on average capacity factors of 30-35%, making wind an attractive option in the country.[1]

In 2006, there were 27 wind farms operating in Australia. Some of the largest wind farms in Australia are:

  1. Wattle Point (SA) - 90.75MW
  2. Alinta/Walkaway (WA) - 90MW
  3. Lake Bonney Stage 1 (SA) - 80.5MW
  4. Cathedral Rocks (SA) - 66MW

Australia's first commercial wind farm, Ten Mile Lagoon Wind Farm near Esperance in Western Australia, has been operating since 1993.

Wind turbine efficiency

Typical wind power coefficient

The efficiency of a wind turbine is defined as the proportion of electrical energy that is derived from the kinetic energy available in the prevailing wind. In theory, a 100% efficiency would imply that all of the wind energy is converted to electrical energy, leaving still air on the lee side of the turbine. In practice, this is neither desirable nor achievable. The maximum theoretical mechanical efficiency of 59% is known as the Betz limit. [9]

The horizontal axis turbines of the type commonly used in Australia exhibit varying efficiencies levels at different wind speeds. The maximum efficiency can approach 50%, but the average efficiency over a range of wind speeds is usually closer to 20%.[10][11] Turbines are usually optimised to enable maximum efficiency at a pre-determined wind speed in order to maximise the maximum energy over a long period. This needs to take into account that the available power is proportional to the cube of the wind speed - in other words, a doubling a wind speed increases the available energy eight-fold.

Competitiveness of wind power

Making comparisons between wind and other sources of energy can be difficult because of the cost profiles associated with wind developments. The vast majority of the costs associated with wind developments are upfront capital costs. The operating costs are relatively low, with each additional unit of wind power costing very little to produce. By comparison, conventional gas and coal developments have large capital costs, as well as significant operating costs. The difference in cost profiles creates difficulties when trying to compare the cost of alternative energy sources.[3]

Despite these complexities, most of the data indicate that wind energy is one of the most cost efficient sources of renewable energy and that when the costs associated with pollution are factored in it is competitive with coal- and gas-fired power stations.[4]

Environmental impact

Wind power is one of the most environmentally friendly sources of renewable energy

Australia is the highest emitter of greenhouse gases per capita in the developed world.[12][13] It is one of the major exporters of coal, the burning of which causes CO2. It is also one of the countries most at risk from climate change according to the Stern report. This is partially because of the size of its agriculture sector and long coastline.

A wind farm, when installed on agricultural land, has one of the lowest environmental impacts of all energy sources:[5]

  • It occupies less land area per kilowatt-hour (kWh) of electricity generated than any other energy conversion system, apart from rooftop solar energy, and is compatible with grazing and crops.
  • It generates the energy used in its construction in just 3 months of operation, yet its operational lifetime is 20-25 years.
  • Greenhouse gas emissions and air pollution produced by its construction are very tiny and declining. There are no emissions or pollution produced by its operation.
  • In substituting for base-load (mostly coal power) in mainland Australia, wind power produces a net decrease in greenhouse gas emissions and air pollution, and a net increase in biodiversity.
  • Modern wind turbines are almost silent and rotate so slowly (in terms of revolutions per minute) that they are rarely a hazard to birds.[6]

Landscape and heritage issues may be a significant issue for certain wind farms. However, when appropriate planning procedures are followed, the heritage and landscape risks should be minimal. Some people may still object to wind farms, perhaps on the grounds of aesthetics, but their concerns should be weighed against the need to address the threats posed by climate change and the opinions of the broader community.[7]

Overseas experience has shown that community consultation and direct involvement of the general public in wind farm projects has helped to increase community approval.[14]

Major wind power companies

Pacific Hydro

Pacific Hydro is an Australian company that specialises in electricity generation using renewable energy. Its focus is on hydroelectricity and windpower. Wind power stations owned by Pacific Hydro include:

Suzlon

Suzlon Energy Australia Pty. Ltd. (SEA), is based in Melbourne, and is a subsidiary of Suzlon Energy A/S of Aarhus, Denmark. Suzlon will install 45 units of its S88 – 2.1 megawatt wind turbines for AGL at the Hallett Wind Farm to be located on the Brown Hill Range, which is situated approximately 220 kilometers north of Adelaide.[8]

Wind Prospect

In March 2005 the 46MW Canunda Wind Farm in South Australia, developed by Wind Prospect, was commissioned. A second South Australian wind farm, Mt Millar Wind Farm, was commissioned in January 2006 and this provides a further 70MW of generation. More recently, a third wind farm has reached financial close for Wind Prospect in South Australia. This is the 95MW Hallett Wind Farm which is expected to be fully commissioned late in 2008.

In Australia, Wind Prospect has more megawatts of capacity approved by local councils than any other developer in the country. In all, nine wind farms totalling over 700 MW have planning approval.
