Welcome to Collgar Wind Farm

Collgar Wind Farm is a $750 million renewable power project at Merredin in Western Australia’s central wheatbelt. Merredin farmers have leased portions of their properties to Collgar Wind Farm for the largest single stage wind farm in the southern hemisphere to date.

The giant Collgar project has been developed by international investment bank UBS and the Retail Employees Superannuation Trust (REST), Australia’s largest superannuation fund by membership with 1.8 million members. The UBS International Infrastructure Fund (UBS IIF) retains a 60 per cent ownership of the project with the remaining 40 per cent held by REST.

The Collgar Wind Farm, built over a land envelope of 18,000Ha, has 111 Vestas V90 turbines with a power production capacity of 206MW, generating on average 792,000 MWh per year, enough to provide electricity to power a small city of 125,000 homes. This is more than double the size and power generating capacity of the next two biggest wind farms in WA, at Walkaway near Geraldton and Emu Downs near Cervantes.

The Collgar Wind Farm has almost doubled the level of renewable energy in the South West Interconnected System (SWIS) from 5 per cent to 9 per cent. Government policy has established a target 20 per cent renewable energy by 2020 across Australia.

Collgar Wind Farm generates and delivers clean, renewable electricity into the SWIS each year, therby making a major contribution to Western Australia's greenhouse gas reductions. These reductions will be equivalent to taking 160,000 cars off the road and planting 1,000,000 trees. Collgar Wind Farm will produce enough electricity to power approximately 125,000 Western Australian homes with renewable energy.



  • The Collgar Wind Farm Board of Directors and representatives of Collgar management visited Merredin College on Thursday 4 September to meet the Collgar VET Scholarship winners (Jamieson Mitchell-Smith and Slade Johnston) and to observe first hand some of our pre-primary students putting the primary computer room to good use.

  • Perth-based urban artist Darren Hutchens travelled to Merredin September 12-14, 2014 to take on a new community art project, transforming the changing rooms at the Merredin District Olympic Pool.

  • Study pays off: Merredin College principal Beverley Stanes, proud parent Bruce Smith, scholarship winner Jamieson Mitchell-Smith, Collgar Wind Farm chief executive officer Thomas Scott-Morey, scholarship winner Slade Johnston and Collgar site superintendent Barry Sayers.
