I snapped this picture today of these giant turbines at the Canunda Wind Farm between Mount Gambier and Caprneter Rocks near Tantanoola.

There are 23 turbines and the farm has a total capacity of 46 megawatts, which yields approximately 135,000 megawatt-hours of electricity per year.

This provides clean electricity for about 30,000 South Australian homes and reduces carbon dioxide pollution by around 135,000 tonnes per year.

Each turbine consists of a 67-metre high tower and 40-metre long blades, making it 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. They weren’t moving at all in the still conditions today.

The distribution line is 16km long and transports the generated electricity from the wind farm to a nearby substation at Snuggery. The distribution line traverses mostly roadside verges.

There are some pictures here of the $92.5 million project during construction.

The wind farm was opened in March 2005.
