Clough, as a project contractor to GE Vernova, delivered the engineering, procurement, and construction scope for Tallawarra Stage B, Australia's first net zero emissions hydrogen and gas capable power station in Yallah, New South Wales.

Tallawarra Stage B is a 300+ megawatt expansion of the existing Tallawarra A power station, involving the construction of a 420 megawatt Open Cycle Gas Turbine Power Plant. Works include the construction of a high voltage switchyard, an unloading station, a distillate tank, connecting gas pipelines, gas receiving and conditioning stations, transformers, switchgear, a control room and an administration building.

At the peak of construction, the project created hundreds of jobs and injected about $300 million into the local economy. The plant is capable of generating electricity for 150,000 homes with only 30 minutes’ notice. The project addresses the need for fast-start flexible capacity, to complement renewables coming into the system.
