The wind farm generates and delivers clean, renewable electricity into the SWIS each year, thereby making a major contribution to Western Australia’s greenhouse gas reductions.


These reductions are equivalent to taking 150,000 cars off our roads each year, or planting up to nine million trees. Collgar Wind Farm produces enough electricity to power between 125,000 and 150,000 Western Australian homes with renewable energy.

Collgar Wind Farm is wholly owned by the Retail Employees Superannuation Trust (Rest).


Rest is one of the largest profit-to-member industry superannuation funds in Australia, with over 1.8 million members and around $66 billion in funds under management (as at 30 June 2021). Rest was established in 1988 and is open to all Australians. For more information visit www.rest.com.au .
