Located 175km north of Perth, the 214MW wind farm has been built with an A$450m ($348m) investment.
The site was chosen because of its abundant local wind resources and proximity to the grid.
Featuring 51 Vestas turbines, the wind facility can generate enough renewable energy to power more than 200,000 Western Australian homes a year.
In its construction phase, which took almost a million hours, the project created almost 150 jobs and opportunities for businesses in the region.
Energy Minister Bill Johnston said: “Congratulations to Alinta Energy, RATCH-Australia and the Dandaragan community on the launch of the Yandin Wind Farm, Western Australia’s largest renewable energy facility.
“With the many challenges faced around Covid-19, it was fantastic to see this project completed, which reflects the hard work and dedication of everyone involved in the project.
“Projects such as this wind farm illustrate the great potential we have in Western Australia to take advantage of the worldwide transition to clean energy technologies.”
Johnston said that renewable energy technologies must be developed in order to minimise energy costs and meet the government’s target of net-zero emissions by 2050.
South West Interconnected System, Western Australia’s main electricity grid, currently has around 1.6GW of renewable energy capacity, including wind farms and rooftop solar systems.
Last October, the Australian Government granted ‘major project status’ to the proposed Asian Renewable Energy Hub, an A$36bn ($25.7bn) wind and solar project.
The project would initially focus on developing 15GW of capacity, before increasing this to 26GW at a later stage.
According to Reuters, the hub would be developed in a 6,500km² area of the Pilbara region.
