Our Story

Producing it's first energy on 14 May 2011, Collgar is a $750m renewable energy project located 25km south east of Merredin in Western Australia.

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 .

The wind farm is built over a land envelope of 18,000 hectares and has 111 Vestas V90 wind turbines with a total power production capacity of 222 megawatts (MW), generating between 630-750 gigawatt hours (GWh) per year, which is enough to provide electricity to power 160,000 homes.

The project location was selected for its unique topography, world class wind resource, favourable community rapport and proximity to the power grid. Wind Power provides a natural, renewable source of energy and is playing an increasing role in reducing global greenhouse gas emissions.

 

The wind farm when first commissioned almost doubled the level of renewable energy in the South West Interconnected System (SWIS) from 5 percent to 9 percent.
 

Collgar 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 210,000 cars off our roads or planting nine million trees.

Collgar also produces major economic benefits for Merredin and its surrounding regions. During the construction phase, Collgar employed up to 150 people over a period of two years, which had a large spin-off for local services. The ongoing financial boost during the life of the project is seen through land rent payments and community projects and sponsorship.

 

The wind farm provides ongoing employment for a team of 10-20 locally based staff. 


Collgar is committed to the local community and is working collaboratively to ensure community expectations are met.
