A substation to link the Coopers Gap wind farm near Kingaroy to the power grid has been completed and energised by Powerlink.
Coopers Gap will be one of Australia's largest wind farms, generating up to 440 megawatts of renewable energy.
The project is expected to create up to 200 jobs during construction, while 52 jobs were supported by the connection to the grid.
Energy minister Anthony Lynham said the substation's completion was a major milestone for the project.
"Queensland has led the way with large-scale solar farm development, but ongoing work at the Coopers Gap Wind Farm highlights the expansion of wind power," he said.
"The economic benefits of large-scale renewable projects are far-reaching.
"Coopers Gap is just one of more than $5 billion worth of large-scale renewable energy projects that are operational, committed or underway in Queensland, creating more than 4600.
Once the 23 wind turbines are installed and generating power later this year, the substation will step up the voltage generated from 33kV to 275kV.
Electricity will then be transported via Powerlink's existing Western Downs to Halys transmission line and into the statewide transmission network.
Powerlink Acting Chief Executive Kevin Kehl said Powerlink was proud to play a key role in connecting one of Australia's largest wind farms to the electricity grid.
