The Willogoleche Wind Farm is located on Willogoleche Hill, just 5km from the town of Hallett in South Australia. The development rights were purchased by Willogoleche Power Pty Ltd, a subsidiary of ENGIE Australia & New Zealand in 2008.
This immense project involved 41 tonnes of steel and 345m3
of concrete for each of the turbine foundations, 17km of internal roads built with 170km of underground cabling that connects to a new ElectraNet substation. Each unit has a tip height of 150m above ground level, with a blade rotor diameter of 130m.
The 32 turbines have a combined generation capacity of 119 MW, giving the wind farm the capability of powering 80,000 homes across the state.
The wind farm is located in one of the windiest areas in South Australia. The area has an average wind speed of 8.6 metres per second. Due to its ideal location, it is surrounded by four neighbouring wind farms; The Bluff, Brown Hill, North Brown Hill and Hallett Hill. After development approval was granted in 2011, native grass species in the area became an Environment Protection and Biodiversity Conservation listed species which involved further studies to be conducted on the site in order to preserve and manage the vegetation.
The Willogoleche Wind Farm was a $250 million project for ENGIE that provides further energy security for South Australia and the National Electricity Market (NEM), further highlighting the company’s commitment to a renewable future.
ENGIE has completed the annual monitoring report under the Environment Protection and Biodiversity Conservation Act for the Willogoleche Wind Farm. You can read it here
