Mahinerangi Wind Farm – Stage 1

Mahinerangi Wind Farm lies 7km north of Lake Mahinerangi, in the South Island of New Zealand. Stage one was completed in 2011 and consists of twelve Vestas V90 turbines, each producing 3MW, for a total capacity of 36 MW. Estimated annual production is 101 GWh. Other infrastructure includes meteorological masts, a 33kV interconnection network, a substation, transmission lines, about 6km of access tracks and operations facilities. Less than 2% of the site’s land area is affected, which is why it can remain a productive farm.

Location: 50km west of Dunedin, Otago | Commissioned: 2011 | Max capacity: 36MW | Average annual output: 101GWh


Tararua Wind Farm – Stage 1 & 2

The Tararua Wind Farm stands on 700 hectares of private farmland in the Tararua Ranges, in the lower North Island of New Zealand. Across all three stages, it is New Zealand’s largest wind farm. Stages one and two have 103 Vestas V47-660 kW wind turbines. Stage one began generating in 1999 and stage two began commercial operation in 2004. These European-made turbines have a 40m hub height and three 23.5 metre (m) blades that turn at 29 revolutions per minute (rpm).

Location: Tararua Ranges, Manawatu | Commissioned: 1999, 2004 | Max Capacity: 68MW | Average annual output: 245GWh

Tararua Wind Farm – Stage 3

Stage three of the Tararua Wind Farm began operating in 2007, utilising 31 Vestas V90-3.0 turbines. These wind turbines have a hub-height of 65m, three 45m blades turning at up to 16rpm, and a total height to the blade tip of 110m. Each turbine has a capacity of 3MW. Together, all three stages of the Tararua Wind Farm produce an average annual power output of over 560GWh.

Location: Tararua Ranges, Manawatu | Commissioned: 2007 | Max Capacity: 93MW | Average annual output: 318GWh



Blayney Wind Farm

Located near Lake Carcoar, south of Blayney, the Blayney Wind Farm consists of 15 Vestas V47-660kW wind turbines. Each of these is 45 metres high with a rotor diameter of 47 metres. The capacity of each turbine is 660kW with a total generation capacity of 9.9MW.

Location: Carcoar Lake, New South Wales | Commissioned: 2000 | Max capacity: 10MW | Average annual output: 18GWh

Crookwell Wind Farm

Crookwell was commissioned in 1998 and utilises 8 Vestas V44-600 kW wind turbines. Crookwell was the first wind farm in New South Wales to be connected to the electricity network in July 1998.

Location: 30km north-west of Goulburn, New South Wales | Commissioned: 1998 | Max capacity: 5MW | Average annual output: 8GWh

Snowtown Wind Farm – Stage 1

The Snowtown Wind Farm sits on the Barunga and Hummocks Ranges, 170km north of Adelaide, in South Australia. Stage one has been generating electricity since 2008. The 47 Suzlon S88-2.1MW turbines have a hub height of 80m and a blade length of 43m. A single Suzlon S95-2.1MW prototype turbine was added in 2011. This S95machine has a hub height of 80m and has a blade length of 46.5m. The electricity generated from Stage one is connected into the Para-Hummocks national electricity line from the stage one substation located Northwest of the Snowtown township.

Location: Near Snowtown, South Australia | Commissioned: 2008 | Max capacity: 101MW | Average annual output: 357GWh

Snowtown Wind Farm – Stage 2

In October 2013, the first power was exported from Snowtown Stage two with final commissioning in October 2014. The 270MW of installed capacity produces an average of 875GWh of electricity per year and offsets the equivalent of 700,000 tonnes of CO2. Stage two is comprised of 10 Siemens SWT-101-3.0MW and 80 Siemens SWT-108-3.0MW turbines. Both turbines utilise permanent magnet generators and direct drive technology. The 10 SWT-101 turbines have a hub height of 80m and a blade length of 49m. The 80 SWT-108 turbines have a hub height of 80m and a blade length of 53m.

The combined Snowtown stage one and stage two wind farm output is 1,232GWh of renewable energy per year. This is enough electricity to power over 200,000 South Australian homes and offset nearly one million tonnes of CO2 produced by thermal electricity generation every year. This CO2 reduction is the equivalent of removing around 225,000 cars from South Australia’s roads. The combined Snowtown Wind Farm is the second largest, and one of the best performing wind farms in Australia.

Location: Near Snowtown, South Australia | Commissioned: 2014 | Max capacity: 270MW | Average annual output: 875GWh
