Workers at the $480 million Lincoln Gap wind farm near Port Augusta have been sent home after International contractor Senvion filed for self-administration proceedings.
The company is reportedly entering a restructuring plan after talks with lenders failed.
Nexif Energy, who own the site, is still committed to completing the project and are ensuring minimal changes to the progress of the wind farm.
The CFMEU says it had up to 100 members on the project that have been stood down with no word on when they can go back to work.
Lincoln Gap Wind Farm was to house 59 turbines, generating 212MW of electricity.
This devastating blow follows the collapse of SolarReserve’s proposed $650 million Aurora solar thermal project in Port Augusta.
