Clough has been awarded Rio Tinto's Cape Lambert power station contract following former contractor Forge Group's collapse.
Clough will be providing the engineering, detailed design, and provision of procurement services for the power station.
The contract includes a 130MW combined cycle power station comprising two dual fuel DLE GE LM6000 gas turbines, waste heat boilers, and a steam turbine air cooled condenser.
It will carry out the work over a period of 12 months.
The former contractor Forge collapsed earlier this year, after declaring insolvency.
